Abstract
A tractor is disclosed having an engine fitted with a speed governor, drive wheels, a transmission connecting the engine to the drive wheels, a controller serving to select the effective transmission ratio, and an engine driven power take-off (PTO) shaft for driving ancillary equipment connected to the tractor. When in a part load operating mode in which the PTO shaft is connected to drive an implement and the tractor is moving, the governor is set to maintain the engine working point to follow a selected speed governor line on the speed/load map of the engine. The controller is operative to initiate a change in the transmission ratio when the engine speed cannot be maintained within the specified tolerance of the desired engine speed.
