Abstract: A self-powered lift apparatus includes a support base, a hitch member, a mast, a movable lift boom, and a power unit. Optionally, the lift apparatus may also include at least one movable stabilizer or support leg. The hitch member is coupled to the support base and is adapted to be received by a hitch receiver on a vehicle. The hitch receiver on the vehicle may provide any one of a hitch socket, a three-point hitch, or a universal mount on a skid-steer vehicle. The lift apparatus is powerable solely by the power unit mounted at the lift apparatus and is operable to move the movable lift boom to lift a person or another implement, without reliance on any power supplied from the vehicle. Optionally, the lift apparatus is at least partially supported in a cargo bed of the vehicle.

Abstract: A plow assembly includes a pair of plow wings which are pivotally mounted at opposite ends of a center plow. Each of the plow wings may pivot between a forwardly angled position and an aligned position. The plow assembly may pivot a trailing plow wing in response to the center plow being urged or angled toward that side of the vehicle. The plow wines may be oriented in their forwardly angled position until the center plow is at least substantially urged or pivoted toward its angled position or toward a position between the center position and the angled position. The trailing plow wing may be pivoted or urged to its aligned position in response to the center plow being substantially urged or pivoted toward its angled position or toward a position between its center position and its angled position.

Abstract: Parts washers are provided including a collection tank, a funnel-bottomed wash cabinet supported on the collection tank, and a cover pivotally supported on the wash cabinet for closing an access opening to the wash cabinet. A screen is mounted in a narrowed section at the bottom of the wash cabinet and is conveniently removable from a front of the wash cabinet. An oil skimmer is pivotally mounted to the tank to allow access to the sump pump without disassembly of the parts washer. In one embodiment, a water seal is provided under a front edge of a door on the wash cabinet. In another embodiment, a rough metal band extends around a turntable and a drive wheel, the rough metal band having prick marks along its length to reduce slippage on the drive wheel.
