Claim:
A hydraulic transaxle, comprising: a transaxle casing supporting left and right axles; a pair of hydraulic motors disposed in the transaxle casing so as to drive the respective left and right axles; hydraulic ports opened outward on the transaxle casing so as to fluidly connect the pair of hydraulic motors to a common hydraulic pump disposed outside of the transaxle casing; and a system for restricting or canceling differential rotation of the pair of hydraulic motors, the system including a valve disposed in the transaxle casing and interposed between the hydraulic ports and the pair of hydraulic motors, wherein the valve is switchable between a first position for allowing a parallel supply of fluid from the hydraulic pump to the pair of hydraulic motors and a second position for restricting or canceling the parallel supply of fluid from the hydraulic pump to the pair of hydraulic motors.
