Abstract

A grading attachment for loader type utility vehicles is provided. The attachment secures to the front of the loader and has an overarching beam which ends in a set of ground engaging wheels. A drawbar is secured to the front of the beam at a ball and socket joint and movably retained at the back of the beam by a vertical channel so that the drawbar can be readily exchanged for another similar drawbar. The drawbar has a sleeve into which a mounting pin may be secured so as to permit the attaching and detaching of a grading implement.

Claims

1. An attachment for loader type utility vehicles comprising:

a) an overarching beam having a proximal end and a distal end wherein the proximal end is detachably secureable to a bucket mount of a utility vehicle, and the distal end is provided with at least one earth engaging wheel.

b) a first member of a ball and socket joint secured to the distal end of the overarching beam,

c) a vertical channel secured to the proximal end of the overarching beam,

d) a drawbar having a proximal end and a distal end and the distal end of the drawbar is provided with a second member of a ball and socket coupling and the proximal end of the drawbar is provided with a cylindrical proximal end segment and the distal end of the drawbar is attached to the distal end of the overarching beam by means of a ball and socket formed of said first and second members of a ball and socket joint and the proximal end segment of the drawbar resides inside said vertical channel so that the drawbar is free to rotate about its longitudinal axis and the proximal end of the drawbar is free to move vertically in said vertical channel, and

e) a landscaping implement attached to said drawbar.

2. The attachment of claim 1 wherein said first member of said ball and socket joint is a ball member having a horizontal axis.

3. The attachment of claim 1 wherein said second member of said ball and socket joint is a socket member assembly having a drawbar plate which is a part of said drawbar and at least two socket plates which are detachably secureable to said drawbar plate to form said socket member assembly.

4. The attachment of claim 1 wherein said channel member is provided with at least one channel liner of a high lubricity wear resistant plastic material.

5. The attachment of claim 1 wherein said drawbar has as a part thereof, a cross member located near said proximal end and said cross member is provided with attachment means for securing adjustment means for raising and lowering and for rotating said drawbar about its longitudinal axis.

6. The attachment of claim 1 wherein said drawbar has as a part thereof, a mounting sleeve which defines a bore through which a mounting pin may pass and be rotatably secured therein.
