Vehicle power transmission system

A vehicle power transmission system comprises: a prime mover (E) mounted on a vehicle body frame; a first axle and a first transaxle (T1) for driving the first axle disposed at one of front and rear portions of a vehicle, the first transaxle (T1) having a first input part (101) projecting outward therefrom, and the first transaxle (T1) having a power take-off shaft (103) projecting outward therefrom opposite to the first input part (101); a speed-changing transmission (4) drivingly interposed between the prime mover (E) and the first input part (101); a second axle and a second transaxle (T2) for driving the second axle disposed at the other rear or front portion of the vehicle, the second axle having a second input part (105); and a power take-off train extended from a leading part to an ending part. The prime mover (E) is disposed between the first transaxle and the second transaxle in a fore-and-aft direction of the vehicle. The leading part of the power take-off train is drivingly connected to the power take-off shaft (103), and the ending part of the power take-off train is drivingly connected to the second input part (105). The leading part of the power take-off train is separated from the first transaxle (T1) and laterally offset from the prime mover (E).
