A steering wheel is included that pivots one of two steering input members that rotate to independently shift the drive units. A speed and direction pedal is also included, which is communicated to provide direction and magnitude input to the drive units. The steering input and speed and direction inputs coordinate propelling the vehicle such the vehicle turns in the same direction when traveling forward as well as in reverse.
