Abstract

A rake attachment for use on a skid steer, which can be used for multiple lawn and grounds preparation activities, such as grading, filling, leveling and scarifying. The rake attachment of this invention combines several useful attachment functions into a single compact design. The rake attachment includes a support frame that has spaced side support members to define an opening through which a skid steer operator may view the soil being worked. Scarifying teeth extend from the support frame to penetrate the ground for scarifying. The support frame includes tines which work and level the soil as it is being scarified by the scarifying teeth.

Claims

1. A tool, said tool being adapted for use with a skid steer for working soil, said skid steer including a frame chassis defining an operator compartment, a pair of lift arms, first pivot means pivotally connecting said lift arms to said chassis, a mounting plate, second pivot means pivotally connecting said mounting plate to said arms, and power means for pivoting said mounting plate about said second pivot means,

said tool comprising a support member, mounting means connecting one end of said support member to said mounting plate, and a tined member connected to the other end of said support member and having tines for contacting soil, said mounting plate being pivotable into a position disposing said tines at an acute angle with respect to ground, said acute angle being adjustable by pivoting said mounting plate about said second pivot means, to permit soil to be graded and dragged as the skid steer is moved in both forward and reverse directions, and a set of spaced scarifying teeth extending from said support member at one direction with respect to the support member, said tines extending from said support member in a direction other than said one direction.

2. A tool as claimed in claim 1, wherein said support frame and said support member extend transversely across said arms and said scarifying teeth extend from said support member at a ground penetrating angle with respect to the support plate when the arms dispose the support frame at a ground working angle.

3. A tool as claimed in claim 1, wherein the angle between the tines and the scarifying teeth is substantially a right angle.

4. A tool as claimed in claim 1, wherein the angle at which the tines extend from the support member permits the tines to engage the ground at an oblique angle when the support frame is disposed at the ground working angle at which the scarifying teeth penetrate the ground whereby the tines smooth and work the ground scarified by said scarifying teeth.

5. A tool as claimed in claim 1, wherein the support frame includes releasable securing means for releasably securing said scarifying teeth to the support frame to permit removal of the scarifying teeth from the support frame when scarifying is not desired.

6. A tool as claimed in claim 5, wherein said relesably securing means includes tubular sockets carried on said support frame for each of the scarifying teeth, each of said scarifying teeth being received within a corresponding socket when the teeth are attached to the support member, and means for retaining the scarifying teeth in their corresponding sockets.

7. A tool as claimed in claim 6, wherein each of said sockets is defined by a wall, said retaining means including a pin extending through apertures in the walls of the socket and through an aperture in the corresponding scarifying tooth registering with the apertures in the walls of the socket.

8. A tool as claimed in claim 7, wherein said retaining means includes a releasable locking device for retaining the pin.

9. A tool as claimed in claim 7, wherein each of the scarifying teeth are substantially rectangular bars having a ground penetrating end and an opposite end, said opposite end being received within the corresponding socket.

10. A tool as claimed in claim 1, wherein each of the scarifying teeth are substantially rectangular bars having a tapering ground penetrating end to permit the scarifying teeth to chisel into the ground.
