Abstract
A tractor () comprising a power takeoff stub () which is drivingly connected to an engine () by a driveline () is provided. A power takeoff clutch () is provided in the driveline for selectively powering the power takeoff stub. A first hydraulic pump () is drivingly connected to the driveline between the engine and the power takeoff clutch, while a hydraulic pump/motor () is drivingly connected to the driveline between the power takeoff clutch and the power takeoff stub. The pump/motor can operate as a pump driven by the connection to the driveline so as to deliver an additional hydraulic output (B) when required for high capacity implements for example. The PTO clutch () can be employed to selectively control operation of the pump/motor. Alternatively, the pump/motor can serve as a motor driven by a hydraulic connection () to the first hydraulic pump. In combination with disengagement of the PTO clutch, the pump/motor can provide a hydrostatic drive for the PTO stub.
