INTERCHANGEABLE ATTACHMENT FOR COMPACT LOADER

BACKGROUND

The present disclosure is related to implements and accessories for implements that are attachable to power machines. More particularly, the present disclosure is related to an implement machine mount that is useable with a variety of power machine implement interfaces, including either a Bob-Tach® (BT) mounting system (commercially available from Doosan Bobcat North America, Inc. of Bismarck, ND) or a Common Industry Interface (CII) style mounting system without the need for adapters.

Power machines, for the purposes of this disclosure, include any type of machine that generates power to accomplish a particular task or a variety of tasks. One type of power machine is a work vehicle. Work vehicles are generally self-propelled vehicles that have a work device, such as a lift arm (although some work vehicles can have other work devices) that can be manipulated to perform a work function. Some examples of work vehicle power machines include loaders, excavators, utility vehicles, tractors, and trenchers, to name a few.

Unlike skid steers and full-size track loaders, Compact Utility Loaders (CUL), also known as a Mini Track Loader (MTL), do not have a common attachment mounting interface across brands. The consequence is that attachments designed for use on one brand of CUL do not work on all other brands. Over 90% of market volume uses one of two options for an attachment interface. These two options are the ‘Bob-Tach®’ (BT) style of mount and the ‘Common Industry Interface’ (CII) style of mount. There are additional, though less common, styles of mounting interfaces.

Known solutions to this problem use a stand-alone product to adapt from a compact utility loader's mounting style to a dissimilar attachment's mounting style. Other earlier attempts require an operator to remove and/or replace part of an attachment tool in order to make it compatible with the compact utility loader. The disclosure describes an apparatus that eliminates the need for an adapter or for such intrusive retrofitting.

The discussion in this Background is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

SUMMARY

In one aspect, an apparatus is configured for mounting to an implement and configured for coupling to a first implement carrier of a first power machine, and configured for coupling to a second implement carrier of a second power machine. The apparatus comprises a first bracket, a first engagement plate portion, a first lip, a second engagement plate portion and a second lip. The first bracket extends rearward and is configured for attachment to the implement. The first engagement plate portion is configured to contact the first implement carrier. The first lip is configured for engagement with a top edge of the first implement carrier, wherein the first lip is angled with respect to the first engagement plate portion. The second engagement plate portion is configured to contact the second implement carrier. The second lip is configured for engagement with a top edge of the second implement carrier, wherein the second lip is angled with respect to the second engagement plate portion.

In another aspect, a method provides compatibility of an implement to a first implement carrier of a first power machine and to a second implement carrier of a second power machine. The method comprises attaching a first bracket of an apparatus to the implement; operating the first power machine to engage a top edge of the first implement carrier with a first lip and first engagement plate portion of the apparatus; and operating the second power machine to engage a top edge of the second implement carrier with a second lip and second engagement plate portion of the apparatus.

DETAILED DESCRIPTION

The disclosed machine mount attachments can be used on various implements to allow for their operation on power machines having implement carriers of either a Bob-Tach® type or a Common Industry Interface type.

The concepts disclosed in this discussion are described and illustrated with reference to exemplary embodiments. These concepts, however, are not limited in their application to the details of construction and the arrangement of components in the illustrative embodiments and are capable of being practiced or being carried out in various other ways. The terminology in this document is used for the purpose of description and should not be regarded as limiting. Words such as “including,” “comprising,” and “having” and variations thereof as used herein are meant to encompass the items listed thereafter, equivalents thereof, as well as additional items.

The disclosed concepts can be practiced on various implements and various power machines, as will be described below. Representative implements 100, 100′, 100″ on which the embodiments can be practiced and representative power machines 10 and 10′ to which the implement can be operably coupled are illustrated in diagram form in FIGS. 1-3 and described below before any embodiments are disclosed. For the sake of brevity, only particular implement and power machine combinations are discussed in detail. However, as mentioned above, the embodiments below can be practiced on any of a number of implements and these various implements can be operably coupled to a variety of different power machines. Power machines, for the purposes of this discussion, include a frame, in some instances at least one work element, and a power source that is capable of providing power to the work element to accomplish a work task. One type of power machine is a self-propelled work vehicle. Self-propelled work vehicles are a class of power machines that include a frame, work element, and a power source that is capable of providing power to the work element. At least one of the work elements is a motive system for moving the power machine under power.

Referring now to FIG. 1, a block diagram illustrates basic systems of power machine 10 as are relevant to interact with implement 100 as well as basic features of implement 100, which represents an implement upon which the embodiments discussed below can be advantageously incorporated. At their most basic level, power machines for the purposes of this discussion include a frame 20, a power source 25, a work element 30, and, as shown in FIG. 1, an implement interface 40. On power machines such as loaders and excavators and other similar work vehicles, implement interface 40 includes an implement carrier 50 and a power port 60. The implement carrier 50 is typically rotatably attached to a lift arm or another work element and is capable of being secured to the implement. The power port 60 provides a connection for the implement 100 to provide power from the power source to the implement. Power source 25 represents one or more sources of power that are generated on power machine 10. This can include either or both of pressurized fluid and electrical power.

The implement 100, which is sometimes known as an attachment or an attachable implement, has a power machine interface 110 and a tool 120, which is coupled to the power machine interface 110. The power machine interface 110 illustratively includes a machine mount 112 and a power port 114 for coupling with power machine 10. Machine mount 112 can be any structure capable of being coupled to the implement interface 40 of power machine 10. Power port 114, in some embodiments, includes hydraulic and/or electrical couplers. Power port 114 can also include a wireless electrical connection, as may be applicable on a given implement. While both machine mount 112 and power port 114 are shown, some implements may have only one or the other as part of their power machine interface 110. Other implements, such as a bucket and some simple forklifts, would not have a power port 114 at all (e.g., See FIG. 3). Some other forklifts may have an actuator for adjusting its tines vertically, horizontally, rotationally, or by extending them in response to power signals received from the power machine 10 at power port 114.

In instances where a power machine has a specific implement carrier, the machine mount 112 will include a structure that complements the specific implement carrier. For power machines without an implement carrier, the machine mount includes features to directly mount the implement 100 to the power machine 10 such as bushings to accept pins for mounting the implement to a lift arm and an actuator for moving the implement.

For the purposes of this discussion, implements can be categorized as simple or complex. A simple implement has no actuated work element. One example of a simple implement is a bucket or a forklift without actuable tines. A complex implement has at least one actuable work element such as a forklift with actuable tines. Complex implements are further divided into those that have one actuable work element and those that have multiple work elements. Some complex implements include features of a simple implement.

In FIG. 1, the implement 100 illustrates a tool 120 for a complex implement with a single work element 124. The tool 120 includes a frame 122, which is coupled with or integral to the machine mount 112. A work clement 124 is coupled to the frame 122 and is moveable in some way (vertical, horizontal, rotation, extension, etc.) with respect to the frame 122. An actuator 126 is mounted to the frame 122 and the work element 124 and is actuable under power to move the work element with respect to the frame. Power is provided to the actuator 126 via the power source 25. Power is selectively provided in the form of pressurized hydraulic fluid (or other power source) directly from the power machine 10 to the actuator 126 via power ports 60 and 114.

FIG. 2 illustrates an implement 100′, which depicts a complex, multi-function implement. The features in FIG. 2 that are similarly numbered to those in FIG. 1 are substantially similar and are not discussed again here for the sake of brevity. Implement 100′ has one or more additional work elements 124″, which are shown in block form. Each work element 124″ has a corresponding actuator 126″ coupled thereto for controlling movement of the work element 124″. A control system 130 receives power from the power source 25 via power port 114′ and selectively provides power to the actuators 126′ and 126″ in response to signals from operator inputs. The control system 130 includes a controller 132, which is configured to receive electrical signals from the power machine 10 indicative of operator input manipulation and control power to the various actuators based on those electrical signals. The controller 132 can provide electrical signals to some or all of the actuators 126′ and 126″ to control their function. Alternatively, the controller 132 can control optional valve 134, which in turn controls actuation of some or all of the actuators 126′ and 126″ by providing pressurized hydraulic fluid to the actuators.

Although not shown in FIG. 2, in some instances, controller 132 can receive signals indicative of operator actuation of user inputs that are mounted on the implement, as opposed to the power machine. In these applications, the implement is controlled from an operator position that is located remotely from the power machine (i.e. next to the implement 100′).

FIG. 3 illustrates an implement 100″, which depicts a simple implement. The features in FIG. 3 that are similarly numbered to those in FIG. 1 are substantially similar and are not discussed again here for the sake of brevity. Implement 100″ has one or more engagement structures 128 that is fixedly or moveably attached to the frame 122″. Unlike a work element, which is powered by an actuator to move relative to the frame to perform a work function, the engagement structure can engage a medium to perform, in combination with the power machine, work. For example, a simple bucket has an engagement structure including a cutting edge; a defined volume holds soil or material that is collected into the bucket. As another example, tines of a forklift can be mounted to the frame of the forklift implement for engaging a pallet. Such tines can be adjustable, but in many cases, the tines themselves are not moveable under power to perform work, but are instead engagement structures for engaging and supporting a load to be lifted and/or carried.

A power machine interface 110 can include a machine mount 112 in the form of a generally planar interface plate that is capable of being coupled to an implement carrier 50 on a loader. In embodiments, various types of machine mounts can be employed. The power machine interface can also include a power port (e.g., see interfaces 110 and 110′ of FIGS. 1 and 2 respectively), or not such as with the power machine interface 110″ of FIG. 3. When the power machine interface includes a power port, the power port can include hydraulic conduits that are connectable to conduits on a power machine so that pressurized hydraulic fluid can be selectively provided to an actuator on the implement to actuate a connected working element. The power port can also include an electrical connection, which can be connectable to a controller (such as controller 132 of FIG. 2) and actuators on a valve (such as valve 134). The controller and valve can be included in a control system (such as control system 130) on the implement for controlling functions thereon.

FIGS. 4A-4B illustrate a loader 200, which is one particular example of a power machine of the type illustrated in FIGS. 1-3 in which the embodiments discussed below can be advantageously employed. The loader 200 is a tracked loader and more particularly, a mini-loader. A mini-loader for the purposes of this discussion is a small loader relative to other compact loaders such as traditional skid-steer loaders and compact track loaders; typically, a mini-loader does not have an enclosed operator cab. Some mini-loaders have a platform on which an operator can ride, which serves as an operator station. Other mini-loaders can be operated by an operator who walks behind the loader. Still other mini-loaders have a platform that is moveable or removable to allow an operator to alternatively ride on the platform or walk behind the loader. The illustrated loader 200 is a tracked loader, though in some embodiments, the tractive elements can be wheels.

The loader 200 should not be considered limiting, especially as to features that the loader 200 may have described herein that are not essential to the disclosed embodiments. Such features may or may not be included in power machines other than the loader 200 upon which the embodiments disclosed below may be advantageously practiced. Unless specifically noted otherwise, embodiments disclosed below can be practiced on a variety of power machines, with the loader 200 being only one of those power machines. For example, some or all of the concepts discussed below can be practiced on many other types of stand-on work vehicles such as mowers, aerators, and spreaders, to name but a few examples. Moreover, while the illustrated embodiment shows a platform configured for a standing operator, the described platform suspension system can also be used for a seating platform, for example.

In an exemplary embodiment, loader 200 includes frame 210. The frame 210 supports a power system 220, the power system 220 being configured to generate or otherwise provide power for operating various functions on the power machine. Frame 210 supports and generally encloses the power system 220 so that the various components of the power system 220 are not visible in FIGS. 4A-4B. The frame 210 also supports a work element in the form of a lift arm structure 230 that is selectively powered by the power system 220 in response to signals from an operator control system 260 and can perform various work tasks. The lift arm structure 230 in turn supports an implement carrier 50a, which is configured to receive and secure various implements to the loader 200 for performing various work tasks. The loader 200 can be operated from an operator station 250 from which an operator can manipulate various control devices to cause the power machine to perform various functions, discussed in more detail below. In an exemplary embodiment, the frame 210 also supports a traction system 240 that is also selectively powered by the power system 220 in response to signals from the operator control system 260. The traction system 240 is configured to propel the power machine over a support surface.

Various power machines that can include and/or interact with the structures and/or functions of embodiments discussed below can have various frame components that support various work elements. The elements of frame 210 discussed herein are provided for illustrative purposes and are not necessarily the only type of frame that a power machine on which the embodiments discussed below can be employed, unless otherwise specifically indicated. The frame 210 of the loader 200 includes an undercarriage or lower portion 211 of the frame and a mainframe or upper portion 212 of the frame that is supported by the undercarriage. The mainframe 212 of the loader 200 is attached to the undercarriage 211 such as with fasteners or by welding the undercarriage to the mainframe. The mainframe 212 includes a pair of upright portions 214 located on either side and toward the rear of the mainframe that support the lift arm structure 230 and to which the lift arm structure 230 is pivotally attached.

The lift arm structure 230 is illustratively pinned to each of the upright portions 214. The combination of mounting features on the upright portions 214 and the lift arm structure 230 and mounting hardware (including pins used to pin the lift arm structure to the mainframe 212) are collectively referred to as joints 216 (one is located on each of the upright portions 214) for the purposes of this discussion. The joints 216 are aligned along an axis 218 so that the lift arm structure is capable of pivoting, as discussed below, with respect to the frame 210 about axis 218. Other power machines may not include upright portions on either side of the frame or may not have a lift arm structure that is mountable to upright portions on either side and toward the rear of the frame. For example, some power machines may have a single arm, mounted to a single side of the power machine or to a front or rear end of the power machine. Other machines can have a plurality of work elements, including a plurality of lift arms, each of which is mounted to the machine in its own configuration. The frame 210 also supports a pair of tractive elements 242 on either side of the loader 200, which on the loader 200 are track assemblies.

The lift arm structure 230 shown in FIGS. 4A-4B is one example of a lift arm structure that can be attached to a power machine such as the loader 200 or other power machines on which embodiments of the present discussion can be practiced. The lift arm structure 230 has a set of lift arms 232 that are disposed on opposing sides of the frame 210. (It should be noted, however, that a lift arm structure may incorporate only a single lift arm or exhibit other configurations.) A first end 232A of each of the lift arms 232 is pivotally coupled to the power machine at joints 216 and a second end 232B of each of the lift arms is positioned forward of the frame 210 when in a lowered position as shown in FIG. 4A. The lift arm structure 230 is moveable (i.e., the lift arm structure can be raised and lowered) under control of the loader 200 with respect to the frame 210. That movement (i.e., the raising and lowering of the lift arm structure 230) is described by a radial travel path, shown generally by arrow 233. For the purposes of this discussion, the travel path 233 of the lift arm structure 230 is defined by the path of movement of the second end 232B of the lift arm structure.

The lift arms 232 are each coupled to a cross member 236 that provides increased structural stability to the lift arm structure 230. A pair of actuators 238, which on loader 200 can be hydraulic cylinders configured to selectively receive pressurized fluid from power system 220, are pivotally coupled to both the frame 210 and the lift arms 232 at pivotable joints on either side of the loader 200. The actuators 238 are sometimes referred to individually and collectively as lift cylinders. Actuators 238 can instead be other types of actuators, such as electric actuators. Actuation (i.e., extension and retraction) of the actuators 238 causes the lift arm structure 230 to pivot about joints 216 and thereby be raised and lowered along a fixed path illustrated by arrow 233.

The lift arm structure 230 shown in FIGS. 4A-4B is representative of one type of lift arm structure that may be coupled to the power machine 200. Other lift arm structures, with different geometries, components, and arrangements can be pivotally coupled to the loader 200 or other power machines upon which the embodiments discussed herein can be practiced without departing from the scope of the present discussion. For example, other machines can have lift arm structures with lift arms that each have two portions (as opposed to the single piece lift arms 232) that are pivotally coupled to each other along with a control arm to create a four-bar linkage and a substantially vertical travel path or at least more vertical than the radial path of lift arm structure 230. Other lift arm structures can have an extendable or telescoping lift arm. Still other lift arm structures can have several (i.e. more than two) portions segments or portions. Some lift arms, most notably lift arms on excavators but also possible on loaders, may have portions that are controllable to pivot with respect to another segment instead of moving in concert (i.e., along a pre-determined path) as is the case in the lift arm structure 230 shown in FIGS. 4A-4B. Some power machines have lift arm structures with a single lift arm, such as is known in excavators or even some loaders and other power machines. Other power machines can have a plurality of lift arm structures, each being independent of the other(s).

An example of an implement interface 270 is provided at the second end 232B of the lift arms 232, as shown in FIG. 4A. The implement interface 270 includes an implement carrier 50a that is configured to accept and secure a variety of different implements to the lift arm structure 230. Such implements have a machine interface that is configured to be engaged with the implement carrier 50a. The implement carrier 50a is pivotally mounted to the second end 232B of each of the arms 232. An implement carrier actuator 237 is operably coupled to the lift arm structure 230 and the implement carrier 50a and is operable to rotate the implement carrier with respect to the lift arm structure 230. Other examples of power machines can have a plurality of implement carrier actuators.

The implement interface 270 also includes an implement power source 235 available for connection to an implement on the lift arm structure 230. The implement power source 235 can include pressurized hydraulic fluid ports to which an implement can be coupled. The pressurized hydraulic fluid ports selectively provide pressurized hydraulic fluid for powering one or more functions or actuators on an implement. The implement power source can, but need not, also or alternatively include an electrical power source for powering electrical actuators and/or an electronic controller on an implement. An electrical power source can also include electrical conduits that are in communication with a data bus on the loader 200 to allow communication between a controller on an implement and electronic devices on the loader 200.

The lower frame portion 211 supports a pair of attached tractive elements 242. Each of the tractive elements 242 has a track frame 243 that is coupled to the frame 210. The track frame 243 supports and is surrounded by an endless track 244, which rotates under power to propel the loader 200 over a support surface. Various elements are coupled to or otherwise supported by the track frame 243 for engaging and supporting the endless track 244 and cause it to rotate about the track frame 243. For example, a sprocket 246 is supported by the track frame 243 and engages the endless track 244 to cause the endless track to rotate about the track frame. An idler 245 is held against the track 244 by a tensioner (not shown) to maintain proper tension on the track 244. The track frame 243 also supports a plurality of rollers 248, which engage the track and, through the track 244, the support surface on which the weight of the loader 200 is distributed.

The operator station 250 is positioned toward the rear of the frame 210. While an operator stands on the platform 252, the operator has access to a plurality of operator control inputs 262 that, when manipulated by the operator, can provide control signals to control work functions of the power machine 200, including, for example, the traction system 240 and the lift arm structure 230. Operator control inputs 262 can include joysticks, switches, buttons, knobs, levers, variable sliders, roller-ball inputs and other multi-axis input devices, for example. In the embodiment shown in FIGS. 4A and 4B, the operator station 250 is open to the back of the power machine 200. Similar other power machines, including other mini-loaders, can include operator stations toward the rear of the respective frames, without necessarily being open to the back of the power machines.

Display devices 264 are provided in the operator station to give indications of information relatable to the operation of the power machines in a form that can be sensed by an operator, such as, for example audible and/or visual indications. Audible indications can be made in the form of buzzers, bells, and the like or via verbal communication. Visual indications can be made in the form of graphs, lights, icons, gauges, alphanumeric characters, and the like. Displays can be designed to provide dedicated indications, such as warning lights or gauges, or dynamic to provide programmable information, including programmable display devices such as monitors of various sizes and capabilities. Display devices can provide diagnostic information, troubleshooting information, instructional information, and various other types of information that assists an operator with operation of the power machine or an implement coupled to the power machine. Other information that may be useful for an operator can also be provided.

FIGS. 5 and 6 show an implement 100a configured as a hydraulic back hoe and having a Bob-Tach® style machine mount 112a. As shown in FIG. 6, a power machine 10a having a Bob-Tach® style implement carrier 50a is positioned proximate the machine mount 112a for a coupling thereto, so that the implement 100a can be operated by and on the power machine 10a. FIG. 7 is a perspective view of an implement 100b configured as a power rig and having a CII style machine mount 112b. The power machine 10b illustrated in FIG. 7 has a CII style implement carrier 50b that is positioned in proximity to the implement 100b for coupling thereto.

FIGS. 8-18 illustrate five embodiments of a machine mount attachment 300 that allows for a connected implement (not shown) to be coupled to both Bob-Tach® style and CII style implement carriers without an extra adapter part. A first exemplary machine mount attachment is shown in FIGS. 8 and 9 and is designated with reference number 300a. A secondary exemplary machine mount attachment is shown in FIGS. 10 and 11 and is designated with reference number 300b. A third exemplary embodiment of a machine mount attachment is illustrated in FIGS. 12 through 14 and designated with reference number 300c. A fourth exemplary machine mount attachment is illustrated in FIGS. 15 and 16 and designated with reference number 300d. A fifth exemplary embodiment of a machine mount attachment is illustrated in FIGS. 17 and 18 and is designated with reference number 300c.

Thus, five specific embodiments of a machine mount attachment 300 are described, and in some cases they will be differentiated with lowercase letters following the reference number. However, in many aspects, the machine mount attachments are similar; descriptions of attachment 300, 300a, 300b, 300c, 300d or 300e apply to all embodiments unless otherwise specified. This convention also applies to other similarly numbered elements. The attachments 300 allow most common implements 100 to be used across brands of compact utility loaders without requiring the manufacture of parts on-demand per a customer's requirements and without requiring additional inventory to be stocked in order to have product for all styles of interface.

For customers, the attachments 300 eliminate the need for known adapters that permit the use of a CII attachment on a BT style CUL, and vice versa. Use of an adapter decreases the functional operating capacity of a CUL due to the added weight and the change in center of mass of the attachment forward of the CUL. Some brands of attachments use a bolt-on interface that can be removed/replaced to match the style of CUL. Both methods require an operator to buy additional equipment to use an attachment on a non-compatible CUL.

Attachments 300 provide the following advantages to the manufacturer: 1) Reduce the number of top level attachment assemblies by having a single design for each style and size of attachment. This will simplify inventory management and reduce the time and effort required for future changes and revisions. 2) Eliminate the need to manufacture product on demand to meet a customer's requirements. This will preserve a manufacturer's goal of being able to deliver product quickly. 3) Reduce the amount of inventory required to be held at product distribution centers. This can help preserve a position as an e-commerce brand by reducing reliance on a dealer network that stocks many options for each locale; rather, the manufacturer will be able to stock fewer products, thereby reducing risk associated with predicting and stocking redundant quantities for different styles of interfaces.

Attachments 300 also provide the following advantages to end use customers: 1) The buying experience will be enhanced by simplifying compatibility with different brands of CUL. 2) Customers will be able to use implements on different brands of CUL. This will allow customers who currently own a brand of CUL with one style of mount to change to a brand with the other style of mount without the need to replace their implements. 3) Customers will not need to invest in additional adapter plates. 4) Rental companies will be able to rent implements to users of CULs with either BT or CII styles of power machine implement carrier. 5) CUL rated operating capacities will be preserved by not needing adapters.

Attachments 300 also allow a customer a wider range of implement choices, regardless of their brand of CUL. Additionally, a customer can buy a new CUL and still use all their existing implements. For example, Bobcat® is known as a top-tier brand of CUL—customers will be able to upgrade from competitor brand CULs to the Bobcat® brand MTL without needing to replace their CII implements with BT implements. Machine mount attachments 300 can be used in place of machine mounts 112 on implements 100 to allow the implements 100 to be mounted to power machines 10 having either of a BT style implement carrier 50a or a CII style implement carrier 50b.

FIGS. 8 and 9 are front perspective views of a first exemplary machine mount attachment 300a, in first and second configurations, respectively. Attachment 300a comprises formed steel parts that in FIG. 8 are arranged in a manner that allows for the attachment 300a to be mounted on and secured to a Bob-Tach® style interface carrier 50a as used on the Bobcat® Mini Track Loader power machine.

Referring to FIGS. 5, 6 and 8, attachment 300a can perform as a Bob-Tach® style machine mount 112a, as it also has a top angled lip 302 for receiving the top engagement edges 304 of the Bob-Tach® style implement carrier 50a. Additionally, side flanges 306 of attachment 300a center the attachment 300a on the Bob-Tach® style implement carrier 50a. When the top edge 304 of implement carrier 50a is inserted fully into the top angle lip 302 of attachment 300a, the operator curls up on the implement carrier 50a so that it rests against engagement plate 308. To fully secure the attachment 300a to the power machine 10, pins of the implement carrier 50a are actuated for insertion through apertures 310, thereby locking the implement carrier 50a and the attachment 300a together. Additional details regarding a Bob-Tach® style implement carrier are provided in commonly owned Patent Application Publication US 2015/0275466 for “Implement Interface,” which is hereby incorporated by reference.

For use with BT style implement carrier 50a, plate 312 is secured in a first position as shown in FIG. 8. In the illustrated embodiment, plate 312 is secured to a mounting portion 314 of attachment 300a using bolts or other fasteners 316 such that the plate 312 is in a stored position. Thus, the entire engagement plate 308 can contact implement carrier 50a. In an exemplary embodiment, an angled mounting portion 314 is provided at a lower extent of aperture 332. Mounting portion 314 has a structure and position similar to lip 328 of FIGS. 17 and 18. Aperture 332 is an opening that extends through engagement plate 308. In the first configuration of FIG. 8, plate 312 is attached to mounting portion 314 so that it extends rearward of aperture 332. For use with BT style implement carrier 50a, alternatively, plate 312 can be removed so that its weight is not present.

In the second configuration of FIG. 9, plate 312 is attached to mounting portion 314 so that it extends forward of aperture 332. In this configuration, attachment 300a is configured for use with a CII style implement carrier 50b. To obtain this configuration, plate 312 is removed from mounting portion 314, such as by removal of fasteners 316. Plate 312 is then reattached to mounting portion 314 so that it extends forward beyond engagement plate 308, thereby forming a CII lip 328 for receiving the top engagement edge 330 of CII implement carrier 50b, illustrated in FIG. 7. When the top edge 330 of implement carrier 50b is inserted fully into the top angle lip 328 of attachment 300a, the operator curls up on the implement carrier 50b so that it rests against a laterally central, lower portion of engagement plate 308. To fully secure the attachment 300a to the power machine 10b, pins of the implement carrier 50b are actuated for insertion through apertures 318 in lower flange 320, thereby locking the implement carrier 50b and the attachment 300a together. In an exemplary embodiment, the CII features 312, 320 of attachment 300a are centered laterally between the side flanges 306. In use, implement carrier 50b is centered laterally under plate 312 between the small side flanges of plate 312. The CII lower flange 320 is positioned at a bottom of the attachment 300a, as are the BT lower flanges 311. Thus, lower structures of an attached implement 100 are at a nearly consistent position relative to a supporting ground surface regardless of whether the implement 100 is attached to the power machine 10 by a BT implement carrier 50a or a CII implement carrier 50b.

FIGS. 10 and 11 show front and rear perspective views, respectively, of a second exemplary machine mount attachment 300b. In an exemplary embodiment, attachment 300b includes one or more plates 322 configured to be moved between first and second positions. Each plate 322 is secured in attachment 300b using a spring-loaded mechanism 324 such that the plate or plates 322 are biased by a spring force into the first position (shown in FIGS. 10 and 11). Two plates 322 are shown, configured to be received within apertures 332 when pushed to pivot back on hinges 325. However, it is contemplated that lip 328 can be formed from fewer or more plate(s) 322 and corresponding aperture(s) 332. As shown in FIG. 11, the spring-loaded mechanism 324 can be secured to one or more of a backside of engagement plate 308, a support bracket 326, or other attachment components or structures. In the first position, the plate(s) 322 are arranged to function as a CII lip 328 for receipt of the top edge 330 of CII implement carrier 50b.

In an exemplary embodiment, support plates 340 connect engagement plate 308 and support brackets 326. Additionally, gussets 342 connect engagement plate 308 and support brackets 326. In an exemplary embodiment, apertures 338 are provided in support brackets 326, and apertures 344 are provided in support plates 340. The apertures 338 and 344 are sized and shaped to balance a desired reduction in weight with a desired structural integrity of attachment 300b. Additionally, apertures 332 are at least large enough to receive plates 322 when they are pivoted back toward or beyond engagement plate 308 about hinges 325.

For use with a BT style implement carrier 50a, when the implement carrier 50a is moved into contact with engagement plate 308, the advancing surface of the BT style implement carrier 50a applies a force to the plates 322 that overcomes the spring force of mechanism 324 and moves the plates 322 into a second position, wherein each plate 322 is pivoted on hinge 325 so that its bottom edge is in-plane or rearward of engagement plate 308. In this position, the plates 322 are stored and do not engage for mounting purposes with an engagement feature of the implement carrier 50a. Attachment 300b can perform as a Bob-Tach® style machine mount 112a, as it also has a top angled lip 302 for receiving the top engagement edges 304 of the Bob-Tach® style implement carrier 50a. Additionally, side flanges 306 of attachment 300b center the attachment 300b on the Bob-Tach® style implement carrier 50a. When the top edge 304 of implement carrier 50a is inserted fully into the top angle lip 302 of attachment 300b, the operator curls up on the implement carrier 50a so that it rests against engagement plate 308. To fully secure the attachment 300b to the power machine 10, pins of the implement carrier 50a are actuated for insertion through apertures 310 of lower flanges 311, thereby locking the implement carrier 50a and the attachment 300b together.

For use with a CII style implement carrier 50b, plates 322 are biased by spring loaded mechanisms 324 to extend forward of engagement plate 308 to form CII lip 328 for receiving the top engagement edge 330 of CII implement carrier 50b, illustrated in FIG. 7. When the top edge 330 of implement carrier 50b is inserted fully into the top angle lip 328 of attachment 300b, the operator curls up on the implement carrier 50b so that it rests against central lower portion of engagement plate 308. To fully secure the attachment 300b to the power machine 10, pins of the implement carrier 50b are actuated for insertion through apertures 318 in lower flange 320, thereby locking the implement carrier 50b and the attachment 300b together.

In an exemplary embodiment, the CII features 322, 320 of attachment 300b are centered laterally between the side flanges 306. The CII lower flange 320 is positioned at a bottom of the attachment 300b, as are the BT lower flanges 311. Thus, lower structures of an attached implement 100 are at a nearly consistent position relative to a supporting ground surface regardless of whether the implement 100 is attached to the power machine 10 by a BT implement carrier 50a or a CII implement carrier 50b. Because of the automatic motion of plates 322—due to implement interface movement against engagement plate 308 and plates 322 that overcomes the biasing force of spring loaded mechanism 324 toward the configuration shown in FIGS. 10 and 11—attachment 300b allows an operator of a power machine 10 having either type of implement carrier 50 to hook up to an implement 100 connected to attachment 300b without additional work by the operator to move and secure the plates 322.

FIG. 12 is a front perspective view of a third exemplary embodiment of a machine mount attachment 300c. FIG. 13 is a cross-sectional view, taken along line 13-13 of FIG. 12. FIG. 14 is a rear perspective view of the machine mount attachment 300c. Attachment 300c can perform as a Bob-Tach® style machine mount 112a, as it also has a top angled lip 302 for receiving the top engagement edges 304 of the Bob-Tach® style implement carrier 50a. Additionally, side flanges 306 of attachment 300c center the attachment 300c on the Bob-Tach® style implement carrier 50a. When the top edge 304 of implement carrier 50a is inserted fully into the top angle lip 302 of attachment 300c, the operator curls up on the implement carrier 50a so that it rests against engagement plate 308. To fully secure the attachment 300c to the power machine 10, pins of the implement carrier 50a are actuated for insertion through apertures 310 of lower flanges 311, thereby locking the implement carrier 50a and the attachment 300c together.

For use with a CII style implement carrier 50b, CII lip 328 is provided for receiving the top engagement edge 330 of CII implement carrier 50b, illustrated in FIG. 7. When the top edge 330 of implement carrier 50b is inserted fully into the top angle lip 328 of attachment 300c, the operator curls up on the implement carrier 50b so that it rests against a recessed engagement plate 334. To fully secure the attachment 300c to the power machine 10, pins of the implement carrier 50b are actuated for insertion through apertures 318 in lower flange 320, thereby locking the implement carrier 50b and the attachment 300c together. In an exemplary embodiment, the CII features 328, 320, 334 of attachment 300c are centered laterally between the side flanges 306. The CII lower flange 320 is positioned at a bottom of the attachment 300c, as are the BT lower flanges 311. Thus, lower structures of an attached implement 100 are at a nearly consistent position relative to a supporting ground surface regardless of whether the implement 100 is attached to the power machine 10 by a BT implement carrier 50a or a CII implement carrier 50b. Attachment 300c allows an operator of a power machine 10 having either type of implement carrier 50 to hook up to an implement 100 connected to attachment 300c.

FIG. 15 is a front perspective view of a fourth exemplary embodiment of a machine mount attachment 300d. FIG. 16 is a cross-sectional view, taken along line 16-16 of FIG. 15. In an exemplary embodiment, aperture 332 is provided in engagement plate 308, aperture 336 is provided in recessed engagement plate 334, and apertures 338 are provided in support brackets 326. The apertures 332, 336, 338 are sized and shaped to balance a desired reduction in weight with a desired structural integrity of attachment 300d. Attachment 300d can perform as a Bob-Tach® style machine mount 112a, as it also has a top angled lip 302 for receiving the top engagement edges 304 of the Bob-Tach® style implement carrier 50a. Additionally, side flanges 306 of attachment 300d center the attachment 300d on the Bob-Tach® style implement carrier 50a. When the top edge 304 of implement carrier 50a is inserted fully into the top angle lip 302 of attachment 300d, the operator curls up on the implement carrier 50a so that it rests against engagement plate 308. To fully secure the attachment 300d to the power machine 10, pins of the implement carrier 50a are actuated for insertion through apertures 310 of lower flanges 311, thereby locking the implement carrier 50a and the attachment 300d together.

For use with a CII style implement carrier 50b, CII lip 328 is provided for receiving the top engagement edge 330 of CII implement carrier 50b, illustrated in FIG. 7. When the top edge 330 of implement carrier 50b is inserted fully into the top angle lip 328 of attachment 300d, the operator curls up on the implement carrier 50b so that it rests against a recessed engagement plate 334. To fully secure the attachment 300d to the power machine 10, pins of the implement carrier 50b are actuated for insertion through apertures 318 in lower flange 320, thereby locking the implement carrier 50b and the attachment 300d together. In an exemplary embodiment, the CII features 328, 320, 334 of attachment 300d are centered laterally between the side flanges 306. The CII lower flange 320 is positioned at a bottom of the attachment 300d, as are the BT lower flanges 311. Thus, lower structures of an attached implement 100 are at a nearly consistent position relative to a supporting ground surface regardless of whether the implement 100 is attached to the power machine 10 by a BT implement carrier 50a or a CII implement carrier 50b. Attachment 300d allows an operator of a power machine 10 having either type of implement carrier 50 to hook up to an implement 100 connected to attachment 300d.

FIGS. 17 and 18 are front and rear perspective views, respectively, of a fifth exemplary embodiment of a machine mount attachment 300c. In an exemplary embodiment, support plates 340 connect the plate of engagement plate 308 and support brackets 326. Additionally, gussets 342 connect the plate of recessed engagement plate 334 and support brackets 326. In an exemplary embodiment, aperture 332 is provided in engagement plate 308, aperture 336 is provided in recessed engagement plate 334, apertures 338 are provided in support brackets 326, and apertures 344 are provided in support plates 340. The apertures 332, 336, 338, 344 are sized and shaped to balance a desired reduction in weight with a desired structural integrity of attachment 300c. Attachment 300e can perform as a Bob-Tach® style machine mount 112a, as it also has a top angled lip 302 for receiving the top engagement edges 304 of the Bob-Tach® style implement carrier 50a. Additionally, side flanges 306 of attachment 300e center the attachment 300e on the Bob-Tach® style implement carrier 50a. When the top edge 304 of implement carrier 50a is inserted fully into the top angle lip 302 of attachment 300e, the operator curls up on the implement carrier 50a so that it rests against engagement plate 308. To fully secure the attachment 300e to the power machine 10, pins of the implement carrier 50a are actuated for insertion through apertures 310 of lower flanges 311, thereby locking the implement carrier 50a and the attachment 300c together.

For use with a CII style implement carrier 50b, CII lip 328 is provided for receiving the top engagement edge 330 of CII implement carrier 50b, illustrated in FIG. 7. When the top edge 330 of implement carrier 50b is inserted fully into the top angle lip 328 of attachment 300c, the operator curls up on the implement carrier 50b so that it rests against a recessed engagement plate 334. To fully secure the attachment 300e to the power machine 10, pins of the implement carrier 50b are actuated for insertion through apertures 318 in lower flange 320, thereby locking the implement carrier 50b and the attachment 300e together. In an exemplary embodiment, the CII features 328, 320, 334 of attachment 300e are centered laterally between the side flanges 306. The CII lower flange 320 is positioned at a bottom of the attachment 300e, as are the BT lower flanges 311. Thus, lower structures of an attached implement 100 are at a nearly consistent position relative to a supporting ground surface regardless of whether the implement 100 is attached to the power machine 10 by a BT implement carrier 50a or a CII implement carrier 50b. Attachment 300e allows an operator of a power machine 10 having either type of implement carrier 50 to hook up to an implement 100 connected to attachment 300d.
