Abstract
A zero turn radius vehicle with a single steered wheel may include a pair of power transfer mechanisms driving a pair of wheels, an operator control mechanism for controlling the steering, speed and direction of the vehicle and a controller in communication with the control mechanism. A steerable wheel is located adjacent the front of the vehicle frame, on a first side of the vehicle frame and an electric actuator is connected to the controller for steering the front steerable wheel. A second, non-steerable front caster wheel is located on a second side of the vehicle frame. A damper is connected to the non-steered wheel to dampen rotation of the non-steered wheel about a non-steered wheel pivot axis The controller controls the pair of power transfer mechanisms and the electric actuator based on operator input.
