  • Patent number: 5765650
    Abstract: A hydraulic power coupling assembly for coupling a tractor power take-off to various pieces of towed or stationary, powered agricultural equipment. The hydraulic assembly includes a hydraulic pump mounted on the tractor power take-off, a hydraulic motor mounted on a selected piece of agricultural equipment and quick-connect connectors among the pump, motor and the selected agricultural equipment. The pump includes its own reservoir for oil or hydraulic fluid. A shield is incorporated into the pump to eliminate the need for a tractor mounted shield. The hydraulic assembly can be readily removed and transferred to another piece of agricultural equipment to be powered. Thus, the hydraulic assembly is readily available for any powered agricultural equipment needs, while at the same time, removing the exposure to the hazardous area of a tractor's power take-off drive unit.
