摘要：
A speed control unit for controlling the speed of a device driven by a hydraulic motor and in which the speed of the device is controlled by the flow of pressured fluid to the fluid motor. The speed control unit includes a first element which is rotated as a function of the speed of the harvesting machine and a second element which is rotated as a function of the speed of the device with means for automatically varying the flow of fluid whenever either of the element''s rotational speed is varied.
