Abstract
A radial differential speed control system includes a steering angle sensor for a steerable rear wheel, a pedal sensor for sensing an operator input for a desired ground speed at a reference point adjacent an operator seat, and an electronic controller that uses the desired ground speed to calculate differential speeds of a left front drive wheel and a right front drive wheel to reduce the ground speed of a grass mowing machine when the steering angle sensor indicates the steerable rear wheel is turning.
