ABSTRACT:
A cylinder block brake for a hydrostatic transmission or transaxle is provided. A braking member is located in a housing adjacent to a motor cylinder block and has a first position where it is not engaged to the motor cylinder block and a second, braking position where it is engaged to the motor cylinder block. A brake actuation shaft is located in the housing and has a cam portion located along its longitudinal axis. The cam portion is positioned to engage the braking member so that rotation of the brake actuation shaft moves the braking member between the engaged and disengaged positions.
