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.

10. The synthetic turf removal attachment of claim 1, wherein the hydraulic system further comprises a splitter valve capable of ensuring that equal hydraulic force is applied to each of the first and second hydraulic motors.

11. The synthetic turf removal attachment of claim 1, wherein the first and second turf removal tools are turf rolling tools.

12. The synthetic turf removal attachment of claim 11, wherein each turf rolling tool comprises a pair of roller tines.

13. The synthetic turf removal attachment of claim 1, further comprising a first height-adjustable wheel rotatably mounted to the first arm and a second height-adjustable wheel rotatably mounted to the second arm.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The preferred embodiment(s) of the present invention is/are described in conjunction with the associated drawings in which like features are indicated with like reference numerals and in which

(2) FIG. 1 is a partial perspective front view of a first embodiment of the turf removal attachment of the present invention showing a partial turf roll thereon;

(3) FIG. 2 is a front perspective view of a cutter shoe and blade guard of the present invention;

(4) FIG. 3 is a front perspective view of the frame of first embodiment; and,

(5) FIG. 4 is an exploded perspective view of the turf removal attachment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

(6) 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.

(7) 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.

(8) 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.

(9) 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).

(10) 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.
