Abstract:
A bypass mechanism for a hydrostatic transaxle comprising a casing in which is carried a hydraulic motor that rotates on a motor running surface of a center section, the bypass mechanism comprising:a bypass actuator having a first end that extends from the casing and a second end that extends through an opening in the center section adjacent to the motor running surface; a bypass arm connected to the first end of the bypass actuator adapted to rotate the bypass actuator when the bypass arm is rotated; a first retaining ring attached to a first groove formed in the bypass actuator adjacent to an exterior surface of the casing; and a second retaining ring located in a housing bore adjacent the first retaining ring; wherein rotation of the bypass actuator functions to lift the hydraulic motor from the motor running surface of the center section.
