Abstract
A work vehicle is disclosed with a propulsion system that is selectively operable in a first, turning mode or a second, straight mode. The vehicle includes a first traction device, a second traction device, a first steering input, and a second steering input. In the first, turning mode, an operator is able to steer the vehicle left, right, or straight by independently operating the first and second traction devices via the first and second steering inputs. In the second, straight mode, the operator is able to steer the vehicle straight by operating both the first and second traction devices together via one of the first and second steering inputs.
