In described embodiments, a trailer jack mount includes a first hinge plate mountable onto a frame of a vehicle. The first hinge plate has a first side hinge knuckle extending along a side of the first hinge plate and a first rear hinge knuckle extending along a length of the first hinge plate. A second hinge plate has a second side hinge knuckle hingedly connected to the first side hinge knuckle and a second rear hinge knuckle extending along a length of the second hinge plate. A locking bolt is removably insertable through the first rear hinge knuckle and the second rear hinge knuckle. The second hinge plate is rotatable between a first position wherein the second hinge plate is facing the first hinge plate and a second position wherein the second hinge plate is rotated away from the first hinge plate. In either the first position or the second position, the locking bolt is insertable through the first rear hinge knuckle and the second rear hinge knuckle to secure the first hinge plate and the second hinge plate in either the first position or the second position.

An ATV jack may include a clamping engagement member and a leg which pivots which respect to the clamping engagement member a limited amount to enable the jack to lift and hold an ATV. The leg may telescope to allow the jack to be used at variable heights.

A lock for securing semi-trailers. More specifically, the lock of the invention secures the landing gear assembly of a semi-trailer. The lock is made up of a main body, a detachable locking plate, and a lock mechanism. The main body includes a post located in a crankshaft securing portion of the main body. The crankshaft securing portion includes a plurality of crankshaft guides and opposite facing lips which in combination provide a slot to accommodate the detachable locking plate. The post extends outward from an interior surface of the main body. The detachable locking plate fits over at least a portion of the crankshaft securing portion of the main body. The lock mechanism is in operable communication with the detachable locking plate.

A land vehicle is provided having a chassis and having a plurality of corner support units. Each of the corner support units has a support leg which is mounted in a swiveling manner in a bearing shoe, which is rigidly attached to the land vehicle, about a substantially horizontal axis. The length of the support leg is telescopically variable. The support leg comprises at least two pipe sections, which can be displaced relative to each other in the longitudinal direction. A hydraulic cylinder is arranged in the interior of the support leg by means of which the position of the at least two pipe sections relative to each other, and consequently the length of the support leg, can be modified. A separate hydraulic assembly, arranged on the bearing shoe of each affected corner support unit and loading the hydraulic cylinder, is allocated to each corner support unit.

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.

The invention relates to a vehicle jack 12 integrated into a chassis of a vehicle 10 and comprises two jack assemblies 12.1, 12.2 arranged in end-to-end fashion along each side of the vehicle. Each jack assembly includes an elongate drive screw 20 and a pair of legs 9, one of which is pivotally connected to a screw follower 22. In addition, the jack 12 Includes a drive mechanism 14 comprising a bevel gear arrangement which is drivingly connected to the respective drive screws 20. Upon actuation of the drive mechanism 14, the pairs of legs 9 are simultaneously, pivotally displaced relative to the chassis between a retracted position, in which the legs 9 are substantially aligned and disposed at least partially within or around the chassis, thereby not to adversely affect the ground clearance, and an extended position.
