摘要： A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. Each driven wheels is driven by a hydraulic motor with a continuous adjustment of the motor displacement, with the motor being driven by a pump also having continuous displacement. The motor displacement is controlled by an electronic controller in response to stroking of the speed control lever to manage the displacement to provide required drive torques at different points in the stroke. There is provided an automatic steering system having a guidance controller arranged to receive GPS position information which controls the steering by differentially adjusting the displacement of the motors so that the automatic steering is independent of the manual steering which controls the pumps.

摘要： The cutter bar of a header including two sickle bars is driven by a center drive system including a rotary input drive member driven by a motor, first and second rotary members each driven by the drive member about a generally upstanding first rotational axis. Each of the rotary members has an eccentric drive system for driving a respective sickle bar. A flywheel is driven by the rotary input drive member for common rotation therewith and the first and second rotary members are driven by a common drive sprocket to rotate in the same direction about the first and second rotary axes.
