ABSTRACT:
A hydrostatic transmission including a pump, a motor, and a center section provided with a conduit through which the pump and motor are in fluid communication and a valve. The pump, motor and center section are disposed in a housing having a plurality of walls which at least partially define a sump, the conduit being in fluid communication with the sump through the valve when the valve is open. A hydraulic disconnect mechanism is provided which includes a substantially rigid first portion, and a second portion operatively engaged with the first portion and being at least partially resilient. The valve is operably engaged with and opened by the second portion in response to the first portion being in an engaged position, and the valve is not operably engaged with the second portion when the first portion is in a disengaged position.
