Abstract: An articulated handle comprises first, second and third arms pivotally attached together with each arm operatively connected to a respective directional control valve. The handle and first and second control valves, operatively connected to the first and second arms, are mounted on a tractor whereas a solenoid actuated third control valve is mounted on the frame of a bulldozer assembly. A pair of lift cylinders, interconnected between the tractor and frame, are operatively connected to the first control valve whereas tilt and angle cylinders, interconnected between the frame and a bulldozer blade, are operatively connected to the third control valve.
