Beschreibung
Zusammenfassung:	A zero turn mower steering system including left and right motion control levers independently pivotable between forward, neutral and reverse positions to rotate left and right rear drive wheels respectively at forward, neutral and reverse speeds. Left and right position sensors on the left and right motion control levers provide electronic signals to an electronic controller that provides a left front wheel steering angle signal and a right front wheel steering angle signal. Each steering angle signal is based on a distance the electronic controller calculates from each of the left and right rear drive wheels to an instantaneous center point of a turn.
