摘要： A hydrostatic transmission system having a pump and a motor, and a manually controlled bypass valve for creating a short circuit that includes the motor and not the pump, the bypass valve being located closer to the motor than the pump. In a preferred embodiment the bypass passage is located within a housing of a motor of a hydrostatic transmission system and includes a manually controlled valve member that when open and closed respectively permits and blocks flow of fluid between the supply and return line. More particularly, the bypass valve may be integral with the motor of the hydrostatic transmission, and the motor may be a gerotor motor.

摘要： A normally engaged parking brake system for a mower that automatically disengages a parking brake when a steering arm is moved from a park position. Accordingly, the operator does not need to act to set or release the parking brake during normal operation. The system utilizes a hydraulic actuator that releases the parking brake when pressurized fluid is supplied thereto from a hydraulic pump of the mower. A manual pump, which can be configured to be operated by moving a steering arm of the mower, is provided for supplying pressurized fluid to the hydraulic actuator to release to brake in the event the hydraulic pump is not operating.

摘要： A hydrostatic transmission including a hydraulic pump, a hydraulic motor, and an external manifold surrounded by and in contact with air for connecting the hydraulic pump and a hydraulic motor. The external manifold facilitates heat transfer from hydraulic fluid flowing therein to the surrounding air. The design of the hydrostatic transmission with external manifold also allows virtually any desired relative orientation of the pump and motor to be achieved by only changing the shape of the manifold.
