A trailer hitch jack cover includes a housing with a lower open end and configured to be securely disposed over a trailer hitch jack to enclose an operative upper portion of a hitch jack including an adjustment mechanism, a cushion member secured to the housing and covering to an upper surface of the housing, and a fastening mechanism which secures the housing to the hitch jack. The housing is formed of rigid material and includes a side wall which defines an open space therein and an upper member which is fixed to and closes an upper end of the side wall. The cushion member covers an upper surface of the housing upper member.

A jack assembly is shown and describe. The jack assembly may include a first tube having first and second end portions and a central portion between the first and second end portions, and a second tube positioned within the first tube and movable with respect to the first tube. The jack assembly may also include an expanded portion on the first tube, the expanded portion having a larger inner diameter than an inner diameter of the central portion, and a bushing attached to the expanded portion, where the bushing generally prevents contact between the first and second tubes.

A trailer positioning apparatus for aiding in aligning a trailer with a tow vehicle is disclosed. The apparatus comprises a pinion plate which is attached to the landing gear of a trailer; and a rack plate for contacting the ground. The rack plate and pinion plate are pivotally attached at one end. At another end, a pinion engages a series of holes in the rack plate in order to create relative movement between the rack plate and the pinion plate when a force is applied by a user. The trailer may be moved into alignment with the tow vehicle, simplifying the process of attaching the trailer to the tow vehicle.

A work vehicle includes a vehicle body frame supported on a ground surface via a wheel unit and a pair of left and right fenders that can be reversed from a normal posture to a reversed posture via a reversal mechanism, an inside area covered by the fender under its normal posture becoming exposed in the reversed posture of the fender. The fender is maintained under the normal posture and the reversed posture. A first accommodating profile is formed in the surface of the fender, the first accommodating profile being capable of accommodating an article when the fender assumes the normal posture.

Power dollies can be used for moving moveable objects such as trailers. A power dolly could include a frame, a mount and a plurality of wheel sets. The mount could couple the power dolly to a moveable object. One or more of the plurality of wheels sets could be powered. The plurality of wheels sets could be separated into a primary wheel set and one or more support wheel sets. The wheels of the primary wheel set could extend farther from the frame that the wheels of the support wheel sets.
