ABSTRACT:
A hydraulic control system includes a pump, a hydraulic motor and a motor hydraulic circuit interconnecting the pump and the motor. The circuit includes a first hydraulic fluid line extending between the pump and an inlet of the motor and a first control valve located in the fluid line for selectively allowing the flow of fluid between the pump and the motor inlet. A second hydraulic fluid line extends from an outlet of the motor to the first control valve. A circuit is provided for allowing a flow of fluid between the first and second fluid lines. Located in the circuit is a flow control orifice for slowing a flow of fluid between the first and second fluid lines.
