A personal all-terrain vehicle (ATV) includes an engine of vertical shaft type, which has a power output shaft extending vertically above the engine. The engine power output shaft carries one pulley assembly of a belt-type continuously variable transmission (CVT), the second pulley assembly is carried by a vertically extending shaft supported in a bearing assembly secured to the engine. The vertically extending shaft carries shaft power vertically to a level below the engine at which a gear unit of T-configuration is disposed. The T-configuration gear unit provides for selection. of forward/reverse directions of travel for the vehicle, and also provides for splitting of shaft power between forward and rear differentials of the vehicle.
