ABSTRACT:
A reverser system for the feeder chain of a combine harvester comprises a hydraulic motor mounted on a slide and operated by a cylinder to move from a retracted position to a forward operating position. In the operating position the mechanical coupling connects the shaft of the hydraulic motor to a drive sprocket connected to the feeder chain. Hydraulic fluid to the cylinder and to the hydraulic motor is tapped from the lift cylinders of the combine from a solenoid operated diverter valve. A control unit controls the supply of the pressurized fluid to the cylinder while delaying the supply of fluid to the hydraulic motor so that the mechanical coupling is connected while stationary before the hydraulic motor starts. This arrangement can be provided by simple mechanical devices providing an inexpensive drive system.
