Abstract
This invention relates to controls of an agricultural tractor having a rotary cultivating mode and a draft control mode for performing a plowing operation. A conventional tractor has a controller for accelerating front wheels to be faster than rear wheels when the front wheels are steered to a predetermined reference angle. Such control is effected only in the rotary cultivating mode. In the agricultural tractor according to this invention, different reference angles are automatically set for the rotary cultivating mode and draft control mode. In addition, different reference speeds are set for the rotary cultivating mode and draft control mode. When the tractor runs faster than the reference speeds, the front wheels are prevented from becoming faster than the rear wheels even if the front wheels are steered to the reference angles.
