During operation the wheel apparatus can be removed from the tilling machine.

Description

TECHNICAL FIELD

The subject matter disclosed herein relates generally to apparatuses and methods designed to facilitate the transport and storage of tilling machines, and more particularly to providing a multi-positionable, auxiliary wheel apparatus for a tilling machine, such as a minitiller.

BACKGROUND

The popularity of gardening has brought about an array of tilling machines designed to lessen the physical labor associated with gardening. Designed for smaller gardening applications, such as cultivating, the mini-tiller has become a popular choice among gardeners. However, the compact and lightweight design of mini-tillers often precludes the incorporation of wheels on the machines. While the lack of wheels decreases the weight of the machine and improves maneuverability while tilling, the portability of the mini-tiller is compromised when the mini-tiller tines are disengaged and there are no wheels on which to transport the machine.

Therefore, a wheel apparatus would be advantageous to facilitate the transport of tilling machines, particularly mini-tillers. Further, a wheel apparatus that is readily removable would not take away from the maneuverability and compact design of the mini-tiller when in use as a tilling machine.

Wheel assemblies are currently available on tilling machines, particularly self-propelled tillers and tillers designed for larger applications. Some tilling machines have wheels that are vertically adjustable to allow for a working mode in which tiller tine depth can be selectively controlled at a plurality of depths, as well as a transport mode wherein the tiller tines are maintained above the soil and the weight of the tilling machine is supported on the wheels such that the tilling machine can be rolled during transport. Other tilling machines utilize the wheels as a means of propulsion by directing power from the engine to the ground engaging wheels. Still yet, other tilling machines utilize wheels as a stabilizing means while in working mode.

SUMMARY

In accordance with the present disclosure as described further herein, wheel apparatuses and methods are provided for the transport and storage of tilling machines such as mini-tillers.

It is therefore an object of the present disclosure to provide novel apparatuses and methods for transporting and storing a tilling machine, such as a mini-tiller, by providing a wheel apparatus that can be attached to a tilling machine in one or more positions to allow both transport and storage of the tilling machine.

An object having been stated hereinabove, and which is achieved in whole or in part by the subject matter disclosed herein, other objects will become evident as the description proceeds when taken in connection with the accompanying drawings as best described herein below.

DETAILED DESCRIPTION

Reference will now be made in detail to the description of the present subject matter, one or more examples of which are shown in the figures. Each example is provided to explain the subject matter and not as a limitation. Features illustrated or described as part of one embodiment can be used in another embodiment to yield still a further embodiment. It is intended that the present subject matter covers such modifications and variations.

Referring now to FIGS. 1a and 1b, and as one example of a tilling apparatus generally designated T, tiller T is illustrated as a mini-tiller. It can be appreciated, however, that the present disclosure is not limited to mini-tillers and that the present disclosure can apply to and be used with any suitable tilling apparatus.

Continuing with the example provided in FIGS. 1a and 1b, tiller T can till soil by rotating tiller tines generally designated TT. Tiller T can be powered by a motor M that can be, for example, a gasoline powered motor. Motor M can transfer power to tiller tines TT such that tiller tines TT can be rotated to till soil. Tiller T can include a handle generally designated H that can permit a user to guide and steer tiller T. A drag bar DB can be attached to or part of tiller T and can be used for contacting the soil during tilling to provide stability and create resistance during operation, thereby retarding the forward motion of tiller T. In accordance with the subject matter disclosed herein, a wheel apparatus generally designated WA can attach to drag bar DB to facilitate transportation of tiller T when in a transport position (FIG. 1a) and to facilitate storage of tiller T when in a storage position (FIG. 1b).

Wheel apparatus WA can be fixedly attached to tiller T in any suitable manner as known to those of skill in the art. In one aspect of the present disclosure, as illustrated in FIG. 2, wheel apparatus WA can comprise a mounting frame generally designated MF that can be removably attached to drag bar DB. In other aspects, wheel apparatus WA can be linked or attached to tiller T with coupling methods known to those of skill in the art.

With continuing reference to FIG. 2, drag bar DB can be substantially L-shaped and can have a substantially vertical portion 10 and a substantially horizontal portion 12. Vertical portion 10 of drag bar DB can define a plurality of holes generally designated DBH for varying the attachment height of drag bar DB to the rear portion of tiller T for facilitating a transport position and a storage position, wherein horizontal portion 12 of drag bar DB can extend rearwardly therefrom. A drag bar pin DBP can be received within holes DBH for securing drag bar DB to tiller T. A key K can be attached to drag bar pin DBP to prevent removal of drag bar pin DBP when inserted into holes DBH. Horizontal portion 12 of drag bar DB can define an aperture generally designated 14 that can receive a locking pin P1 for lockably attaching drag bar DB to mounting frame MF.

With further reference to FIG. 2 mounting frame MF of wheel apparatus WA can have a sleeve portion SP that can define an interior space generally designated IS. Horizontal portion 12 of drag bar DB can be configured to be slidably received within interior space IS. Sleeve portion SP can define a hole generally designated H1 that can align with aperture 14 of drag bar DB. Locking pin P1 can be inserted into hole H1 of sleeve portion SP and can then be guided through aperture 14 of drag bar DB. Locking pin P1 can exit sleeve portion SP through a corresponding hole H1 on the side of sleeve portion SP opposite the insertion side.

Mounting frame MF can further include an axle housing AH. Axle housing AH can be substantially elongate and hollow for receiving an axle A. Axle A can be rotatably mounted within axle housing AH and can extend horizontally from both ends of axle housing AH to provide for the attachment of a plurality of wheels W to each end of axle A. Thus, axle A and wheels W can rotate freely. A plurality of endcaps 20 can be attached to wheels W to prevent axle A from extending beyond wheels W. In one aspect, wheel apparatus WA can comprise one wheel W that can be attached to mounting frame MF such that a user could transport tiller T by rolling tiller T on wheel W and the user can also stabilize tiller T in a storage position in a stabilizing manner similar to that of a tripod.

In accordance with the present subject matter, wheel apparatus WA can be attached to drag bar DB in one or more positions for providing various functions. A transport position is illustrated in FIGS. 3a, 4a, 5a, 6a, 6b and 8a. The transport position can be used when the user is not operating tiller T in a tilling manner. When in the transport position, wheel apparatus WA can be used to lift and maintain tiller tines TT off the ground surface. Thus, the user can transport tiller T to a storage location or other area to be tilled without awkwardly attempting to carry tiller T or to roll tiller tines TT over a damaging surface. The user can attach wheel apparatus WA to tiller T by sliding drag bar DB within sleeve portion SP and coupling thereto with locking pin P1. In the transport position, sleeve portion SP of mounting frame MF and horizontal portion 12 (FIGS. 5a, 6a, 6b and 8a) of drag bar DB can be fixedly oriented substantially above axle A. By attaching wheel apparatus WA to drag bar DB in the transport position, tiller T and tiller tines TT can be maintained in a spaced-apart manner above a ground surface generally designated GS, as illustrated in FIG. 8a. With wheel apparatus WA attached to tiller T in the transport position, the weight of the tiller T can be supported by wheels W of wheel apparatus WA, wherein tiller T can be rolled during transport.

As illustrated in FIGS. 3b, 4b, 5b, 7a, 7b and 8b, wheel apparatus WA can be attached to drag bar DB of tiller T in a storage position. The storage position can be used when tiller T is stored in a standing position. When in the storage position, wheel apparatus WA can be used to provide additional stability to tiller T, thereby aiding in preventing tiller T from easily being tipped over due to the irregular shape of tiller tines TT. In the storage position, wheel apparatus WA is configured to permit tiller tines TT to rest on the ground surface. Thus, wheels W and tiller tines TT can more evenly distribute the weight of tiller T to provide a more stable storage position. The user can attach wheel apparatus WA to tiller T by sliding drag bar DB within sleeve portion SP and coupling thereto with locking pin P1. In the storage position, sleeve portion SP of mounting frame MF and horizontal portion 12 (FIGS. 7a, 7b and 8b) of drag bar DB can be fixedly oriented substantially below axle A. By attaching wheel apparatus WA to drag bar DB in the storage position, the tines TT of tiller T and wheels W of the wheel apparatus WA can be simultaneously in contact with ground surface GS, as shown in FIG. 8b, to stabilize tiller T, which is particularly useful for storage of tiller T.

In another aspect, the user can easily switch wheel apparatus WA from a transport position to a storage position by removing locking pin P1 and switching the position of wheels W. Wheel apparatus WA can be easily changed between the transport and storage positions, and visa-versa, by removing locking pin P1, sliding wheel apparatus WA off of drag bar DB, flipping the wheel apparatus WA over, and re-attaching wheel apparatus WA to drag bar DB. Wheel apparatus WA can be configured such that no vertical adjustment of vertical portion 10 of drag bar DB is necessary when switching from storage position to transport position or vice-versa. In such a configuration, drag bar pin DBP can remain in the same hole DBH in both positions. Vertical portion 10 of drag bar DB can be adjusted vertically using various holes DBH and drag bar pin DBP to adjust wheel apparatus WA to accommodate various sized tillers T. Additionally, wheel apparatus WA can be an auxiliary device that can be completely removed and remain unattached when desired such as, for example, when tiller T is in operation.

It can therefore be seen from the foregoing that the embodiments disclosed herein provide apparatuses and methods to transport and store a mini-tiller or other suitable tilling machines by attaching, in a transport or storage position, an auxiliary wheel kit apparatus to the drag bar of the mini-tiller.

It will be understood that various details of the disclosed subject matter may be changed without departing from the scope of the disclosed subject matter. Furthermore, the foregoing description is for the purpose of illustration only, and not for the purpose of limitation.
