Claim 13:
14. A disker attachment for mounting on a skid-steer tractor to cut ground, the skid-steer tractor having:
a tractor frame having a front end, a rear end, and transversely opposite sides;
ground engaging members supported on the sides of the tractor frame and arranged for moving the tractor frame across a support surface in a forward working direction;
a pair of pivotal arms each supported on a different one of the sides of the tractor frame for upward and downward movement relative to the tractor frame about a transversely oriented pivot axis, the pivotal arms extending forwardly from rear ends at which the pivot axis is located to front ends of the pivotal arms located at or adjacent the front end of the tractor frame; and
a mounting member supported between the front ends of the pivotal arms relative to a transverse direction of the tractor frame in a manner for pivotal movement about a generally horizontal axis extending between said front ends, the mounting member being configured to removably receive a work tool in a manner such that the work tool is movable therewith;
the disker attachment comprising:
a disker frame having a forward end and a longitudinally spaced rear end;
a mounting coupling at the rear end of the disker frame configured for coupling to the mounting member of the skid-steer tractor;
a set of cutting disks mounted at the forward front end of the disker frame in forwardly spaced relation to the mounting coupling;
the set of cutting disks comprising a transversely-extending row of cutting discs across the forward end of the disker frame;
and a levelling drag operatively supported on the disker frame rearwardly of the set of cutting disks and configured for levelling the cut ground material behind the cutting disks when moving in the forward working direction.
