Landscaping and seeding apparatus

Abstract

The present invention is directed to a multi-purpose lawn landscaping and seeding device for attachment to and operation from a prime mover, such as a tractor, and, more particularly, to such a multi-purpose device in which all functions normally carried out by multiple pieces of equipment in preparing, grading, seeding and fertilizing a new lawn, or in renovating an existing lawn, can be performed by a single piece of equipment transported by and operated from a tractor.

Description

BACKGROUND OF THE INVENTION

In landscaping and establishing a new lawn in areas, such as around newly constructed residential or commercial buildings, it is a normal practice, after initial bulldozer clearing of the trees on the land, to plow, level, scarify, rake and pulverize the soil, and to remove trash, rocks and other debris from the area before seeding. Thereafter, the landscaped ground is fertilized, seeded and smoothed. In the past, it has been necessary to use multiple pieces of equipment, or attachments, which are either self-propelled or must be connected to and disconnected from a prime mover, such as a tractor, in performing at least certain of the sequential operations mentioned above. For example, after initial bulldozer operations, it is the practice to backfill relatively large depressions left by the bulldozer where trees have been removed, to plow the ground to a desired depth to break up the soil, to level, rake and scarify the soil, and to pulverize large clods of soil to maintain a uniform texture to the soil. Prior to seeding, trash and debris must be collected and removed from the area to be seeded, generally necessitating the use of a front end loader to remove the same.

Attempts have been made to provide apparatus which perform combined functions similar to certain of the abovementioned landscaping and seeding operations. Very early U.S. Pat. No. 206,120 discloses a road grader attachment having earth breaking, leveling and packing components, while U.S. Pat. No. 629,313 discloses an attachment having combined harrow, pulverizer and crusher components. U.S. Pat. No. 2,839,851 discloses a scarifier and scraper with backfill attachment, and U.S. Pat. No. 3,448,814 discloses a grader bucket construction having plow, scarifier, scraper and roller crusher, with backfill capabilities. U.S. Pat. No. 3,083,652 discloses an earth conditioning and seeding trailer for attachment to a prime mover, while more recent U.S. Pat. No. 4,088,083 discloses a tillage apparatus having detachable plow, scarifier, seeder, and roller attachments. U.S. Pat. No. 3,083,652 discloses an earth conditioning and seeding trailer, while U.S. Pat. No. 3,822,655 discloses a self-propelled lawn conditioning vehicle for smoothing, fertilizing and seeding a lawn. U.S. Pat. No. 3,998,276 discloses a scarifier or plow apparatus capable of deep soil penetration and smoothing operation, and employing a scoop for breaking up the soil prior to compaction.

Although the above-mentioned apparatus provide combinations of components to perform multiple operations in a land grading, or in a seeding operation, it is not believed that any of the apparatus disclosed can perform all of the operations necessary for landscaping, fertilizing and seeding of a lawn area, as with the apparatus of the present invention. In addition, many of the apparatus disclosed in the above-mentioned patents are quite bulky and difficult to handle, obviously limiting their use to relatively large open areas, and not suitable for narrow, close areas around buildings and between concrete driveways, trees, and the like.

It is therefore an object of the present invention to provide a multi-purpose lawn landscaping and seeding device for attachment to and operation from a prime mover, such as a garden tractor, which is of compact, relatively lightweight construction, and which can be utilized to perform, with a single piece of equipment, all of the necessary functions for normal landscaping and seeding of a lawn.

It is another object to provide an apparatus of the type described which may be easily transported to a landscaping site and readily manipulated in confined or small areas of the site to perform all the necessary operations required.

It is a more specific object to provide a multi-purpose lawn landscaping and seeding device which permits plowing, scarifying, raking, fertilizing, seeding and pulverizing and which further may be utilized for scraping, leveling and backfilling of the ground, as well as for removal of trash, rocks and other debris from the site.

SUMMARY OF THE INVENTION

It has been found that a multi-purpose lawn landscaping and seeding device including a support frame and means supporting the frame for transport may be provided with an elongated pan having a bottom, wall, opposed side walls, and upstanding front and rear walls, with the front wall defining a ground scraper blade. Means are provided for mounting the pan on the frame for pivotal movement about its longitudinal axis between a first position wherein the bottom wall of the pan is generally horizontally disposed, and a second position wherein the bottom wall is generally upright with the front wall scraper blade extending downwardly and forwardly for engagement with the ground. Ground scarifying means include a row of scarifier tines pivotally attached to and spaced along the length of a forward undersurface portion of the pan with the tines extending downwardly from the pan to engage the ground when the pan is in the first position. Means is provided for moving the pan between the second position wherein the scraper blade is in engagement with the ground to remove soil therefrom, and the first position wherein the pan is generally horizontally disposed to transport removed soil therein.

DESCRIPTION OF A PREFERRED EMBODIMENT

Referrring more particularly to the drawings, the landscaping and seeding device of the present invention comprises a main frame broadly designated at 10 having a generally horizontal pipe support member 12 and a pair of horizontal support arms 14, 16 extending rearwardly thereof from respective end portions of the support member 12. Mounted between the support arms 14, 16 for pivotal movement about its longitudinal axis is an elongate pan broadly designated at 18, having a bottom wall 20, opposed side walls 22, and upwardly flaring front and rear walls, 24, 26, respectively. The front wall 24 extends a distance beyond side walls 22 and serves as a ground scraper blade, as will be explained.

The support frame 10 is removably attached to a three-point hitch of a prime mover, such as a tractor (not shown), by means of a yoke member 28 which is fixedly secured to a midportion of elongate support member 12 and extends generally upwardly therefrom. Yoke member 28 is provided with three attachment points 29 for receipt of respective arms of the three-point hitch of the prime mover, which arms are secured to the yoke by means of pins, bolts or the like. Thus, the landscaping and seeding device may be raised and lowered out of and into contact with the ground for respective transporting and ground-engaging operative use at the work site.

Attached to and extending along the length of frame support member 12 is a row of spaced plow tines 30 and a row of ground scarifying and raking tines 32. As best seen in FIGS. 1 and 2, the plow tines and scarifying tines are supportably disposed in oppositely extending directions on common support means, such as a plurality of rectangular channel members 34 which are rotatably received about support member 12 and are adjustably secured against rotation in a desired position by locking pins 36 which mate with aligned holes in the channel members and pipe support member 12. Thus, one or more of all of the channel members 34 may be adjustably rotated and positioned about support member 12 to dispose the plow tines 30 or the scarifying tines 32 downwardly from the support member for engagement with the ground.

As best seen in FIGS. 2 and 3, pivotally attached by a pivot arm 38 to a forward undersurface portion of the pan 18 is a second row of scarifying tines 40 which extend in spaced relation along the length of the pan between support arms 14, 16 and are positioned in staggered relation with respect to individual of the scarifying tines 32 in the row of tines on support pipe 12. Integrally attached to pivot arms 38 supporting the row of tines 40 and extending rearwardly at an acute angle from the tines is an elongate soil backfill blade 42. In the position of the pan as seen in FIG. 1, the scarifying tines 40 are pivotally movable about a generally horizontal axis and extend in a downward direction to engage the ground. Rearward pivotal movement of the tines 40 during their use is limited by stop members or triangular plates 44, attached to the upper rear face of the backfill blade. As can be seen, the stop members 44 engage the undersurface or bottom wall 20 of pan 18 and maintain the scarifying tines in downward, ground-engaging position when the device is moved forwardly over the ground by a prime mover.

Pivotally attached to a rear undersurface of the pan 18 by means of lever arms 46 attached to side walls 22 of the pan are pulverizing means, shown as a rotatable roller 48 having a plurality of pins or spikes 50 extending from the peripheral surface thereof. During forward movement of the pan across the ground in its position as shown in FIG. 1, the pulverizing roller 48 is yieldingly biased in a downward direction to engage the ground by means of a connecting rod 52 and compression spring 54 which connects each lever arm 46 to the side wall of the pan. In this manner, pulverizing roller 48 is free to engage the ground and break up lumps or clods of soil and smooth the soil, while being able to move upwardly against the force of the compression spring when the pan is pulled over uneven portions of the ground by the prime mover.

As best seen in FIGS. 1 and 2, the bottom portion of the pan is provided with a pair of elongate slots 56, 58 which extend across the width of the pan in forwardly and rearwardly spaced relation. Removably receivable in the pan are a pair of fluent material containing hoppers 60, 62 which, respectively, hold fertilizer and seed for seeding the lawn after the ground has been plowed, cleaned and leveled for seeding. Each of the hoppers 60, 62 is provided with an elongate discharge chute 64 (FIG. 3) which is matingly received in respective elongate slots 56, 58 in the bottom of the pan. Fluent material conveying means, such as an elongate fluted roll 66 is provided adjacent each discharge chute to direct fertilizer and seed from the hoppers through the chutes and onto the ground. Each of the fluted rollers 66 is rotatably driven by means of a motor 68 which is attached to the frame of hopper 60 and is drivingly connected to each of the rollers 66 by means of a belt drive 70.

The motor 68 is connected by electrical wiring (not shown) to the electrical power output of a prime mover, and is provided with an electrical switch 74 which is also mounted on the frame of hopper 60 and extends through a small hole 76 (FIG. 2) in the bottom of pan 18. Switch 74 is engaged by stop member 44 on backfill blade 42 when the stop member is brought into engagement with the bottom of the pan by contact of scarifying tines 40 with the ground and forward movement of the pan across the ground. When switch 74 is engaged by the stop member, electrical power is supplied to the motor from the prime mover to rotate the fluent material conveying rollers 66 in the hoppers and distribute the fertilizer and seed onto the ground through the discharge chutes. In like manner, when the seeding device is lifted by the three-point hitch of the prime mover, scarifying tines 40 disengage the ground and the tines and backfill blade pivot downwardly by gravity to disengage the switch and stop motor 68. In this manner, distribution of fertilizer and seed can be automatically discontinued by the tractor operator when seeding and fertilizing is not desired, such as in turning or transporting the device across paved areas of the work site.

As best seen in FIG. 2, the pan 18 also may be readily employed for scraping, backfilling and leveling of the work site, as well as to transport trash and other debris from the site in the pan. The pan 18 is attached to the support arm 14 of the frame by motor means, such as a hydraulic piston 78, which is connected to the hydraulic system of the prime mover by hydraulic lines (not shown) to provide power for rotating the pan from a generally horizontal position between the support arms, as shown in FIG. 1, to a generally vertically disposed position as shown in FIG. 4. In vertical disposition, the front wall 24 of the pan engages the ground and serves as a scraping blade to remove soil and provide a leveling action when the pan is moved forwardly by the prime mover. In vertical position, the pan is also employed to accumulate soil, rocks, and trash in the pan, and pivotal movement of the pan to horizontal position by the hydraulic motor enables the collected material to be transported in the pan to a desired discharge point outside the area being landscaped.

For backfilling, with the pan in vertically disposed position, the pan may be moved in rearward direction to utilize the backfill blade to smooth and fill in areas, such as around trees or close to adjacent buildings. As can be seen in FIG. 4, when the pan is vertically disposed and moved in rearward direction to utilize the backfill blade to smooth and fill in areas, such as around trees or close to adjacent buildings. As can be seen in FIG. 4, when the pan is vertically disposed and moved in rearward direction by the prime mover, the backfill blade and row of scarifying tines attached thereto pivot forwardly of the pan until the tines 40 engage the undersurface of the front wall 24 of the pan, thus limiting further pivotal movement of the backfill blade and retaining the blade in a downward, ground-engaging position for backfilling and leveling of the soil.

The capabilities of the multi-purpose lawn landscaping and seeding device of the present invention to provide all functions desired in preparing a lawn may be briefly described as follows. After initial clearing of the land by other heavy equipment, the pan 18 is disposed in horizontal position on the frame and plow tines 30 are rotated to a downward, ground-engaging position to break up the surface of the ground to a desired depth. The following row of scarifying tines 40 on the undersurface of pan 18 assist in further breaking up and pulverizing the plowed soil, as well as in raking larger debris, such as roots, limbs and rocks. The pulverizing roller 48 breaks up remaining clods of soil and provides a leveling function to the plowed surface of the ground. After initial soil preparation, or when desired, the pan 18 may be rotated to a generally vertical position and the front scraper blade utilized to provide further leveling and collection of accumulated debris. Any backfilling that may be desired is also accomplished with the pan in vertical position.

After initial ground preparation, the plow tines may be rotated to an upward position to bring the row of scarifying tines on the support bar of the frame into engagement with the ground. The device may then be employed with the two rows of scarifying tines and pulverizing roller to further clean and level the ground, as desired. When it is desired to scarify or break up soil in narrow or confined areas of the work site, only one or more sections of scarifying tines or plow blades may be employed on the front support bar of the frame, with the pan pivoted to an intermediate position to disengage the scarifying blades and roller from the ground.

For fertilizing and seeding operation, the pan is pivoted to horizontal position as shown in FIG. 1, and the fertilizer and seed hoppers are placed in the body of the pan with their discharge chutes matingly received in the elongate slots. As seen in FIG. 2, the discharge chute of the fertilizer hopper is located between the two rows 32, 40 of scarifying tines and just forward of the second row 40 of tines. The discharge chute of the seed hopper is located between the row of scarifying tines 40 and the pulverizing and smoothing roller 48. In this disposition, as the pan is moved forwardly across the ground by the prime mover, the first row of scarifying tines 32 open the soil to receive fertilizer, while the second row of scarifying tines 40 serve to distribute the fertilizer into the soil to a desired depth. Thereafter, seed is distributed by hopper onto the upper surface of the soil and pressed into the soil by the roller. In this manner, the fertilizer and seed can be distributed in optimum positions for future germination and growth of the lawn.

From the foregoing description of a preferred embodiment of the invention, it can be seen that the multi-purpose lawn landscaping and seeding device may be employed after initial clearing of a work site, to landscape, fertilize and seed a lawn, without the necessity of additional equipment or attachments to be transported to the work site.

While a preferred embodiment of the invention has been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the following claims.
