Synthetic Turf Removal Skid Steer Attachment Assembly

Abstract

A turf removal attachment is bolted to a skid steer to allow hydraulic motors thereon to first power cutting blades to form easily removable strips of turf and then, on a lower gear ratio, the drum to which roller tines are attached to spool the strips of turf. Hydraulic circuitry is provided to permit the hydraulic fluid of the skid steer to power the turf removal tools on the turf removal attachment.

Claims

1. A synthetic turf removal attachment adapted to be secured to and powered by a skid steer, said removal attachment comprising: a) a C-shaped frame having a spine with first and second arms extending laterally from first and second longitudinal end portions of said spine, said first and second spaced arms adapted to support turf removal tools; b) first and second motors for powering said turf removal tools mounted on said first and second spaced arms, respectively; c) at least one attachment to a source of energy, said at least one attachment being mounted on said spine, the source of energy adapted to supply power to said first and second motors.

2. The turf removal attachment of claim 1 wherein said first and second motors comprise hydraulic motors for powering said turf removal tools.

3. The turf removal attachment of claim 2 further comprising a supply system for providing hydraulic fluid from a single hydraulic source, said supply system including a splitter valve to divide a fluid stream from the single hydraulic source to ensure equal force is applied to both of said first and second hydraulic motors.

4. The turf removal attachment of claim 3 further comprising hydraulic quick couplers to attach said supply system to a remote hydraulic source on the skid steer being used to manipulate said turf removal attachment.

5. The turf removal attachment of claim 3 wherein said turf removal tools further comprise a pair of cutting blades, each one of said pair of cutting blades being attachable to said first and second arms for energization by said first and second motors, respectively, to slice an artificial turf surface into manageable strips.

6. The turf removal attachment of claim 5 further comprising first and second cutter shoes for partially surrounding said first and second cutter blades.

7. The turf removal attachment of claim 6 further comprising first and second blade guards for overlying a top portion of said first and second cutter blades, respectively.

8. The turf removal attachment of claim 5 wherein said turf removal tools further comprise a pair of roller tines, one each of said roller tines being attachable to said first and second arms, respectively, and being powered by said first and second motors to roll up the sliced turf strips.

9. The turf removal attachment of claim 1 further comprising first and second slidable mounts supporting said first and second arms on said first and second ends of said spine, respectively, and further comprising first and second hydraulic rams to move said first and second arms laterally relative to said first and second longitudinal ends of said spine along said first and second slidable mounts, respectively.

10. The turf removal attachment of claim 1 further comprising first and second height-adjustable wheels rotatably mounted to said first and second longitudinally extending arms, respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

[0016] A first embodiment of the of the present invention is depicted in FIGS. 1 and 4 generally at 20. Turf removal attachment 20 includes a frame featuring a longitudinal spine 24 and two laterally extending arms 26a and 26b. Arms 26a and 26b are connected to spine 24 by means of slidable mounts 28a, 28b (FIG. 4) which telescope into the longitudinal ends 27a, 27b of spine 24, respectively. Hydraulic rams 30a, 30b move arms 26a, 26b in and out for the dual purposes of adjusting the width of the cut of the strip of turf 11 and to permit release of the turf roll 13 once a strip has been completely rolled. Mounting plate 32 is attached to the outside of spine 24 and allows the turf removal attachment 20 to be bolted to the front of a skid steer using the conventional attachment bolts associated therewith through holes 34.

[0017] Arms 26a and 26b have first and second motors 36a, 36b mounted thereon for powering turf removal tools which can be mounted thereon. Preferably, motors 36a, 36b are preferably hydraulic motors which receive hydraulic fluid from a source found on the skid steer (not shown). The hydraulic circuit 40 which makes this possible includes hydraulic quick couplers 42a, 42b which connect to the output and return lines from the hydraulic pump on the skid steer; electric over hydraulic valve assembly 44; first T-connector 46 for hydraulic lines 47 to extend hydraulic rams 30a, 30b and second T-connector 48 for hydraulic lines 49 to retract hydraulic rams 30a, 30b; hydraulic flow divider 50 to ensure equal flow through hydraulic lines 52 to power motors 36a, 36b.

[0018] FIG. 2 depicts a cutter shoe 52 and blade guard 54 which surround turf cutting blade 55 and protect it (and personnel) against contact with foreign materials. Cutting blades 55 are connected to arms 26a, 26b in such a manner as to permit them to be powered by hydraulic motors 36a, 36b and shoes 52 attached to arms 26a, 26b so that they are just above or minimally contact the surface of turf 11.

[0019] Additional turf removal tools are depicted in FIG. 4 and include a pair of roller tines 60 which support roller pipes 62. Roller tines 60 can either have dual arms 61 as shown in FIG. 4 or can alternatively feature two sets of two, or four arms on each tine 60. In either case, tines are spaced in such a manner that roller pipes 62 (FIG. 1) grasp the lead end of turf 11 as roll formation is initiated and maintain a hold on the turf to avoid slippage ensuring a tight roll 13 is formed. Wheels 64 can be height adjusted to accommodate the particular features (thickness, etc.) of the synthetic turf field with which it is used. While the turf removal attachment 20 of the present invention may be made in whatever size desired, a preferred embodiment is capable of cutting turf 11 into strips having widths of 7.5 to 15 feet (2.5-5 yards).

[0020] Various changes, alternatives, and modifications will become apparent to a person of ordinary skill in the art after a reading of the foregoing specification. It is intended that all such changes, alternatives, and modifications as fall within the scope of the appended claims be considered part of the present invention.
