An improved soil leveling apparatus includes a hitch (202 or 302) for connecting the frame to the loader arms and tilt cylinder(s) of a skid steer loader. The hitch (302) includes a hitch plate (304) that can selectively be made rigid with the frame or can selectively be allowed to pivot fore-and-aft relative to the frame. This allows the operator to select the rigid orientation of the frame when it is desired to have the frame be rigid relative to the loader or to select the floating, pivotal orientation depending upon ground terrain and other factors.

[ I claim:] [1.] An apparatus for working soil, the apparatus suited for being connected to a skid steer loader type vehicle having vertically movable loader arms and at least one tilt cylinder, the skid steer loader type vehicle further having an adaptor plate pivotally joined to the loader arms with the at least one tilt cylinder having one end thereof connected to the adaptor plate for pivoting the adaptor plate about the loader arms during activation of the at least one tilt cylinder, comprising:a frame including at least one transverse ground engaging member for working soil; andhitch means mounted on said frame for releasable connection to the loader arms and the at least one tilt cylinder of the skid steer loader, whereby the hitch means includes selectively operable means for placing the frame into either a first rigid orientation relative to the skid steer loader where the frame can then be raised and lowered relative to the ground by the loader arms and the frame can be inclined relative to the ground by the at least one tilt cylinder or into a second floating orientation relative to the skid steer loader where the frame can move up and down relative to the loader arms and at least one tilt cylinder to follow the ground terrain, whereby the user can selectively choose either the first rigid orientation or the second floating orientation of the hitch, wherein the hitch means is configured such that the frame in its floating orientation is pivotally mounted relative to the loader, and wherein the hitch means comprises a hitch plate pivotally connected to the frame for pivotal motion such that the floating orientation of the frame is achieved by pivoting of the frame relative to the hitch plate, and wherein the hitch plate includes means for rigidly connecting the hitch plate to the adaptor plate of the loader.
