ABSTRACT:
A grading attachment for a skid steer loader is provided with steerable wheels that are steered by an actuator. The blade of the grading attachment may be rotatable through 360 degrees by a motor and gear assembly. Actuators may be provided to raise, lower and tilt the blade. The actuators may be hydraulic, and may be controlled by switches mounted on sleeves that may be mounted on the control handles of the loader. The switches may control the flow of hydraulic fluid to the actuators by actuating solenoid valves.
