Abstract: A utility vehicle includes a frame, a power source, and a plurality of steerable structures. Ground engaging members are connected to the steerable structures. Braking mechanisms connected to the steerable structures apply a braking force to the ground engaging members. An operator seating area includes a steering control and a speed control. Controllers receive input from the steering control and the speed control. Motors drive the ground engaging members at different speeds and in different directions. A controller integrates a steering input with a speed input to effect rotation of the steerable structures and effect rotation of the ground engaging members. The steering control, speed control, controllers, steerable structures, and motors are configured to work together to effect Ackermann steering on the ground engaging members. Half of the ground engaging members are located on one opposing lateral side of the frame and experience a braking force when on an inner side of a turning operation.
