摘要： A hydraulic drive apparatus having a center section located in a housing includes a hydraulic pump and motor disposed thereon and in fluid communication with a hydraulic porting system in the center section. The pump is driven by an input shaft extending out of the housing and the motor drives an output shaft that is generally perpendicular to the input shaft. A bypass actuator extends into the center section perpendicular to both the input shaft and the output shaft. Rotation of the bypass actuator acts to lift the hydraulic motor from the center section to break the hydraulic interface between the hydraulic motor and the hydraulic porting system. The center section may include a second pump and motor with a second hydraulic porting system and a second bypass actuator.
