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.

Hydrostatic transmission having a hydraulic disconnect

A transaxle for a small utility vehicle or implement, including a casing, at least one rotatable shaft disposed in and extending from the casing, at least one brake disc rotatably fixed to the rotatable shaft for rotation therewith, and at least one braking mechanism with at least a portion of the braking mechanism being externally mounted on the casing proximate the rotatable shaft. The braking mechanism includes at least one friction puck disposed proximate the brake disc, and a brake shaft including a cam surface having a longitudinal edge, wherein the brake shaft has an engaged position in which the longitudinal edge is in operative engagement with the friction puck and the friction puck is in pressing engagement with the brake disc and a disengaged position in which the longitudinal edge is out of operative engagement with the friction puck.
