Abstract

Control system for a jack for raising and lowering a lift assembly for hydraulically driven snow blades or other utilitarian accessories. Actuation of the jack allows for proper vertical alignment of the lift assembly for engagement to a vehicle chassis. Once engaged, the jack can be actuated into an inoperative position until the lift assembly is to be removed from the chassis. The control system includes several safety features that prevent the jack from being deployed when the snow blade is raised, and that automatically retract the jack when the snow blade is raised.
