The invention relates to the field of tractors, in particular to a four-wheel-drive tractor which comprises a front frame and a rear frame hinged to each other, a power device, a gearbox, a front drive axle, a front drive axle and front wheels are arranged on the front frame, a cab is arranged on the upper side of the rear frame, a linkage conversion box is arranged at the end, close to the front frame, of the bottom of the rear frame, and a rear drive axle is arranged at the other end of the bottom of the rear frame. The two ends of the rear drive axle are connected with rear wheels, the power device is in transmission connection with the gearbox, the gearbox is in transmission connection with the front drive axle, the front drive axle is connected with the input end of the linkage conversion box through a first linkage shaft, and the output end of the linkage conversion box is connected with the rear drive axle through a second linkage shaft. Cruciform universal joints are arranged between the first linkage shaft and the front drive axle and between the first linkage shaft and the input end of the linkage conversion box. Cruciform universal joints are arranged between the second linkage shaft and the rear drive axle and between the second linkage shaft and the output end of the linkage conversion box. The device is reasonable in structural design, safe, stable and easy to operate and control, and the traction force of the tractor can be improved.
