Abstract: A utility vehicle (20) includes a frame (24), a power source (38), and a plurality of steerable structures (40). Ground engaging members (46) are connected to the steerable structures (40). An operator seating area (34) includes a steering control (84) and a speed control (84). Controllers receive input from the steering control and the speed control. Motors drive the ground engaging members (46) at different speeds and in different directions. A controller integrates a steering input with a speed input to effect rotation of the steerable structures (40) and effect rotation of the ground engaging members (46). The steering control, speed control, controllers (86, 88, 90), steerable structures (40), and motors are configured to work together to control the rotational speed of all of the ground engaging members (46) based upon a steering angle input and the lateral side (28, 30) the ground engaging member (46) is connected to. Other examples include braking mechanisms, adjustable track width, and a sealed tubular frame (24, 26).
