  • Patent number: 10597092
    Abstract: A suspension system for use with a work vehicle. The suspension system may include a suspension tower to which one or more shock absorbers may attach. The tower may permit the shock absorbers to attach at multiple locations, effectively allowing the angular orientation of the shock absorbers, and thus a suspension characteristic of the suspension system, to be altered. The tower may be movable relative to the vehicle, e.g., for crating/shipping.

  • Publication number: 20180049368
    Abstract: An assist handle for assisting an operator with climbing on to, or off of, a ground maintenance vehicle such as a mower, and a ground maintenance vehicle incorporating the same. The assist handle includes, in one embodiment, a grip portion movable between a deployed position, wherein the grip portion is positioned at a deployed elevation configured to assist the operator with ingress to, or egress from, a platform such as a seat; and a stowed position, wherein the grip portion is positioned at a stowed elevation lower than the deployed elevation.

  • Publication number: 20160355186
    Abstract: Various embodiments of a grounds maintenance vehicle are disclosed. The grounds maintenance vehicle can include an electronic control unit (ECU) in electrical communication with a transmission control input, clutch, parking brake, and OP switch of the vehicle. In response to a pre-defined operator activity, the ECU is adapted to manipulate the clutch from an engaged state to a disengaged state, while an engine of the vehicle remains in an operative state, when the transmission control input is in a neutral state and the OP switch changes from an on state to an off state.

  • Patent number: 9288939
    Abstract: Embodiments of the present invention relate to powered vehicles (e.g., lawn mowers) and, more particularly, to a control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity profile control system having an adjustment member that permits altering a ratio between control lever movement and velocity of an associated drive member or wheel. Thus, the system may alter a maximum potential velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position without varying an output level of the power source.

  • Patent number: 8573368
    Abstract: A parking brake actuator system for an outdoor power equipment unit, such as a riding lawn mower, comprises a reversible electric motor that drives a gear reduction assembly. The gear reduction assembly rotates an output shaft at a speed slower than the speed of rotation of the motor. The output shaft has opposite ends that are linked by a pair of actuating rods to a pair of parking brakes. As the motor is rotated in reverse rotary directions, the connecting portions of the rods that are coupled to the parking brakes are moved in opposite, straight line directions to move the parking brakes between brake disengaged and brake engaged positions.
