Abstract

PURPOSE:To prevent the furrowing of mud by the front wheel in making turn by making the turn with the fron axle at high speed revolution. CONSTITUTION:When turning a tractor a braking action is applied to one of the rear wheel 11 by the one of a brake device 12 of the rear axle 7 and the front wheel is steered to the side on which the braking action is applied. The rear axle 7 on the side not braked starts high speed revolution due to the action of the rear differential gear 8 while the drive shaft 4' to the rear axle side starts to rotate at low speed and the drive shaft 4 to the front axle side starts to rotate at high speed due to the action of the intermediate differential gear 1 thereby rotating the front wheel at high speed to make the turn. Due to such high speed revolution of the front wheel 9 the turn of the tractor can be made accurately without almost any furrowing of mud.
