A snow vehicle includes an engine containing a crankshaft and a balancer shaft, a track belt mounted behind the engine, and a front axle for transmitting the driving power from the engine to the track belt. The balancer shaft is located above a line connecting the crankshaft and the front axle and near the rear end of the crankshaft. The snow vehicle improves the stability of the vehicle during operation while minimizing an increase in the dimension of the engine in the vertical direction.
