ABSTRACT:
A pair of axles and a hydrostatic transmission which drives them are housed in a common housing. The hydrostatic transmission comprises a hydraulic pump, with a movable swash plate, which drives a hydraulic motor with pressurized oil. Adjusting the angle and direction of slant of the movable swash plate controls the volume and direction of flow of the pressurized oil. The angle and direction of slant of the movable swash plate are controlled by a rotating member and a shaft housed within the common housing. The rotating member has a contact portion which abuts against an abutting member when transmission is operating in reverse. When the abutting member abuts against the contact portion, a detector operates a switching unit, allowing an alarm to be sounded or the operating device of the vehicle to be disengaged automatically when the vehicle is running in reverse.
