Abstract
An inventive three-point hitch assembly that attaches to the front end of a truck or pickup and supports at three points a plurality of implements or tools. It has a belt-driven power take-off for rotary tools that is controlled by an electric clutch and driven by a pulley attached below the truck engine pulley. A hydraulic lift cylinder raises and lowers the hitch and implement or tool, which by the hitch parallelogram form maintains the implements in a vertical orientation. The lift cylinder hydraulic pressure is supplied by connections to the truck power steering system via electrically controlled solenoid valves.
