Abstract: A lawn maintenance device has a transverse center line, a frame, and a power source including an output shaft attached to the frame. The lawn maintenance device further includes a rotating cutting blade. A left side is located on one side of the transverse center line and a right side located on a second side of the transverse center line. A plurality of ground engaging members are attached to the frame enabling movement of the lawn maintenance device along an associated driven surface. The ground engaging members on the left side are located at a first distance from the transverse center line that is different from a second distance that those on the right side are located from the transverse center line. Another example includes ground engaging members on opposite sides of the lawn maintenance device being located at different distances from a central axis of the cutting blade.

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. 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 control the rotational speed of all of the ground engaging members based upon a steering angle input and the lateral side the ground engaging member is connected to. Other examples include braking mechanisms, adjustable track width, and a sealed tubular frame.
