摘要

The ranking tractor (1) has drive shafts (4,5) whose wheels (8) are mounted rigidly with respect to steering angle. The wheels of drive shafts are driven at independent speed, cornering to speed difference of wheels on both sides of the tractor. The wheels on both sides are driven in opposite directions for rotating the tractor on spot. A wheelbase of drive shafts is set approximately equal to the track width.
