Abstract
A hydrostatic transaxle with a bypass mechanism is disclosed, the transaxle having a center section attached to a housing, an axial piston pump disposed on the center section and driven by an input shaft, and an axial piston motor disposed on the center section having a cylinder block engaged to a motor output shaft. The bypass actuation rod has a cam formed on a first end that engages a block lift member. When the bypass actuation rod is rotated, the cam causes two legs of the block lift member to engage the cylinder block on either side of the motor output shaft and cooperatively lift the cylinder block of the axial piston motor off of center section.
