摘要： A vehicle transaxle system includes a pair of right and left transaxle units equipped on a vehicle. The right transaxle unit supports a single right axle, and the left transaxle unit supports a single left axle. A variable displacement hydraulic pump is disposed in each of the right and left transaxle units so as to be driven by power from a prime mover of the vehicle. A variable displacement hydraulic motor is disposed in each of the right and left transaxle units and is fluidly connected to the corresponding hydraulic pump so as to drive the corresponding right or left axle. A movable motor displacement control member is provided in each of the transaxle unit so as to be moved to change the displacement of the corresponding hydraulic motor. An interlocking connection means is connected to both the movable motor displacement control members of the respective hydraulic motors. The vehicle is provided with a first manipulator for changing displacements of the hydraulic pumps, and is provided with a second manipulator for operating the interlocking connection means. The interlocking connection means is operated by operating the second manipulator so as to synchronously move both the movable motor displacement control members.
