Abstract
A snow thrower including an auger, a chute, a prime mover, and first and second drive wheels powered by the prime mover configured to be driven at variable speeds. The snow thrower further includes a user interface including a left hand grip and a right hand grip configured to pivot within an angular range of motion relative to an axis of rotation to indicate a direction and a magnitude of a desired turn, a steering sensor, and an electronic control unit configured to control operation of the first and second drive wheels. The user interface is pivoted in a first direction about the axis of rotation, the first and second bumpers are configured to contact the first and second force sensors to apply forces to the first and second force sensors to send first and second signals indicative of the forces to the electronic control unit.
