An implement attachment system for a lawn maintenance vehicle includes a box-like structure, where the box-like structure defines a hook configured to cooperate with fasteners located on the lawn maintenance vehicle. A pin is attached to the box-like structure and the pin extends generally downward from the box-like structure. The pin is configured to cooperate with an aperture defined by a portion of an associated frame located on the lawn maintenance vehicle. A resilient force member is attached to the box-like structure. An engagement device is attached to the resilient force member and the engagement device is slidingly attached to the box-like structure.

A platform twist mitigation apparatus operable to extend jacks into engagement with a surface disposed below a platform carrying the jacks, and to alternately extend and retract the jacks to change platform attitude relative to the surface. Tilt sensors are supported at spaced locations on the platform. An electronic control module is programmed to detect a platform twist condition in response to angle data received from the tilt sensors and to mitigate the platform twist condition by operating or modifying the operation of the jacks.

A jack assembly including a telescopic column driven via a gear box, wherein: the gear box is coupled to a rotary input of a drive mechanism that extends and retracts the column; the gear box has only a single input gear and a single output gear that is coupled to the drive mechanism; and the input gear has a connector adapted to be engaged and driven by a portable, hand-held power tool. A jack assembly with a gear box for use as a jockey wheel for attachment to a towed vehicle, to raise and lower a draw bar of the vehicle is also provided.

A recreational vehicle includes a frame, left and right air suspensions, a front jack, a tilt sensor configured to measure lateral and longitudinal tilt data associated with the frame, and a controller. The controller is configured to receive the lateral and longitudinal tilt data to thereby level the frame laterally via operation of the left and right air suspensions and level the frame longitudinally via operation of the left and right air suspensions and the front jack. Methods for performing a leveling operation include utilizing left and right air suspensions of the recreational vehicle in combination with operating a front jack of the recreational vehicle until the recreational vehicle is level along lateral and longitudinal axes.

In a system and method for replacing a vehicle wheel an electric motor with a drive shaft is concentrically connected to a first gear. The first gear may connect to a symmetrical bolt locking gear array having several bolt locking gears arranged such that each bolt locking gear rotates in the same direction that the first gear rotates. Each bolt locking gear may have a cylindrical hole at its center. The cylindrical hole may be outlined with an inner spiral thread, which connects to a set of power bolts that are outlined in an outer spiral thread which interlocks with the inner spiral thread. A power jack system having a plurality of extendable and collapsible bases is provided in the undercarriage of the vehicle to raise and lower the vehicle. An app running on a mobile device may control the raising/lowering of the vehicle and tightening/loosening of the power bolts.

A stabilizer pad for use with stabilizer legs of a work machine is disclosed. The stabilizer pad may include a frame configured for attachment to the stabilizer leg of the work machine. The stabilizer pad may further include a first surface configured to contact a ground surface, the first surface including a resilient member, and the first surface extending a first distance from the frame in a first direction. Additionally, the stabilizer pad may include a second surface configured to contact a ground surface, the second surface including a plurality of rigid members, and the second surface extending a second distance from the frame in the first direction, the second distance being less than the first distance.

A trailer stabilizing device for stabilizing a parked freight trailer, the trailer stabilizing device comprising a frame separate from the support frame of the parked freight trailer, the stabilizing device frame having mounted thereto wheels and a hitch, the stabilizing device including a repositionable jack.
