    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.

    Abstract: Methods and apparatus for a lawn maintenance vehicle park brake and traction drive interlock are provided. A park brake mechanism is selectively operable between an engaged position and a disengaged position. A traction drive is also mounted to the lawn maintenance vehicle, the traction drive having a disable mode which prohibits transmission of a driving force from the traction drive to a drive wheel. A first operable connection between the park brake mechanism and a wheel brake activates the wheel brake. A second operable connection between the park brake mechanism and the traction drive activates the disable mode of the traction drive. A method of controlling a lawn maintenance vehicle with a park brake and traction drive interlock include the steps of providing a lawn maintenance vehicle, providing an operable park brake mechanism, providing a first operable connection, and providing a second operable connection.

    IPC: B62D7/15

    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.

    Abstract: A lawn maintenance vehicle caster wheel assembly includes a suspension and a fork. The fork is rotatably connected to a structural member of the lawn maintenance vehicle. The caster wheel assembly also includes an arm connected to the fork, and the arm is rotatable about an arm axis. The caster wheel assembly further includes a caster wheel mounted to the arm and is rotatable about a wheel axis. A damping member is attached to the fork and the arm such that the caster wheel and the arm can rotate about the arm axis.
