PURPOSE:To improve the weight balance of a machine body by linkingly placing a front wheel speed change gear on the power input part of a front axle case in the captioned vehicle in which power from a transmission provided in the rear of said machine body is transmitted to front wheels via said front wheel speed change gear. CONSTITUTION:In an agricultural tractor, the power of an engine 4 placed on the front part of a machine body frame 3 is transmitted from a main clutch 5 to rear wheels 2 via a transmission 6 formed with main and subspeed change gears placed in the rear of the machine body frame 3. Also, power which is branched off of the sub-speed change gear of the transmission 6 is transmitted from a front wheel output shaft 15 to front wheels 1 via a front wheel speed change gear 10. And, in this case, the front wheel speed change gear 10 the acceleration driving side of which is formed with a multiple disk friction clutch (figure omitted) is placed on the power input part of a front axle case 11. Thereby, a structure without the extremely lopsided supporting load of the front and rear wheels can be obtained.
