Abstract
A lawn mower has driving front wheels and driving rear wheels. The mower includes a mower unit mounted between the front wheels and the rear wheels to be vertically movable, an engine mounted to a front portion of a vehicle body, a transmission case disposed rearwardly of the engine, an HST coupled to a rear wall of the transmission case, the HST having a pump shaft and a motor shaft both projecting forwardly, a charge pump for the HST attached to a front wall of the transmission case, a transmission mechanism disposed inside the transmission case. The transmission mechanism includes an input shaft operably coupling a transmission shaft from the engine to the pump shaft, a first output shaft for transmitting power from the motor shaft to a transmission shaft for the front wheels, a PTO shaft for transmitting power from the input shaft to a transmission shaft for the mower unit, and a second output shaft for transmitting power from the input shaft to the charge pump. The first and second output shafts extend in a fore-and-aft direction of the mower and parallel with the input shaft, the second output shaft being disposed upwardly of the input shaft, the first output shaft being disposed downwardly of the input shaft.
