<p>The system has a steering angle sensor (32) for generating a steering angle signal of front wheels (18) of a tractor. A control unit (30) is provided for controlling a clutch (24) as a function of the sensed steering angle. The control unit determines rear wheel (22) slip from speed sensors and controls the clutch to increase speed ratio in response to an increase in the rear wheel slip.</p> |
