摘要： A three-point hitch converter allows three-point tractor implements to hook to a standard trailer hitch of a vehicle. The hitch converter can attach to a standard trailer hitch receiver the same way as a conventional ball hitch. The hitch converter includes a frame having points to attach tractor-type three-point lift links. The hitch converter also includes mount points for a snowplow-type attachment, a winch, or one or more hydraulic cylinders for lifting the implement.

摘要： An adapter to facilitate attaching non-standard implements to a tractor equipped with a proprietary quick-connect hitch system. An elongated horizontal member, equipped with cylindrical end regions adapted for securing in hook regions of a quick-connect hitch system, carries a ball hitch or other similar universal hitch attachment mechanism. The novel adapter, therefore, allows attachment of implements having a ball hitch, a universal pin type hitch or other non-standard attachment mechanism to tractors equipped with quick-connect hitch systems. The novel adapter is rotatable around its major axis to allow two diverse hitches to be accommodated. For example, a ball-type hitch as well as another type connection my be selected by rotating the adapter 180° around its major axis.

摘要： A hitch device enabling a three-point tractor hitch to be attached to a gooseneck trailer or other similar apparatus (such as a fifth-wheel trailer) is disclosed. A preferred embodiment of the present invention comprises a tubular member having a generally arcuate shape, to which a trailer hitch ball and a pair of metal rods, which function as hitch pins, are welded. Two brackets are welded to the tubular member and serve to support an additional hitch pin. The welded metal rods and additional hitch pin may be secured to a three-point hitch using cotters or other suitable fastener. The device elevates the trailer hitch ball to a sufficient height to accommodate a gooseneck trailer's point of attachment.

摘要： A coupling hook (5) for a lower steering arm of a tractor (1) has a hook body (7) with a bearing recess (8) to receive a bearing ball (6) of a to be coupled implement. The hook body has a recess (9), a through hole (10) between the recess (9) and the bearing recess (8), an exiting aperture (11) connecting to the recess (9) and open to the exterior, and a first support element (12) and a second support element (13). The second support element (13) extends through the exiting aperture (11) and separates the exiting aperture into a first opening portion (14) and a second opening portion (15). A locking pawl (17) is movable between a locking position, where it projects into the bearing recess (8), and a detaching position, where it is retracted into the through hole (10). An adjustment element (30) engages the locking pawl (17) and acts on it to take up the locking position. An opening lever (26) is pivotably connected to the locking pawl (17) and is movably supported on the second support element (13). The opening lever (26) has a locking lug (28) to secure the opening lever in a holding position where the locking lug (28) is retainingly engaged in the second opening portion (15).

摘要： A coupling for coupling, for example, a trailer having a drawbar (2) to a tractor with a three-point linkage device, which has two height-adjustable lower steering arms (3, 4) of which one is laterally adjustable by a lateral strut (11). A first coupling element is mounted on the rear of the tractor. The drawbar (2) is provided with a second coupling element (13). The second coupling element (13) is connectable to the first coupling element (12). The coupling has a bar 14 with two ends. Each end includes a connection element (15) to connect with the lower steering arms (3, 4) of the tractor (1). A guiding mechanism comprises two guiding pins is arranged, distanced from each other, on the bar (14). The guiding bar (14) supports the drawbar (2). The drawbar (2) is guided between the guiding pins (17). The drawbar (2) is adjustable relative to the bar (14) in the longitudinal direction. An abutment (20) mounted on the drawbar belongs to the coupling and limits the longitudinal movement when reversing the tractor (1). The lateral alignment of the second coupling element (13) to the first coupling element (12) can be achieved by shortening and elongating the lateral strut (11).

摘要： The three point hitch mounting system allows a pick up truck to be fitted with a three point hitch so that the pick up truck can be used to transport and operate common agricultural and industrial implements such as mowers, plows, and tillers. In enhanced embodiments, the mounting system provides for a stand that allows the hitch to stand freely when not mounted on a truck, a lift device to allow control of the depth and height of the implement, and a power source and power takeoff ("PTO") for driving powered implements, such as a mower.

摘要： A hitch mechanism includes a coupler frame supporting a plurality of coupler devices for coupling with an implement. A fixed length link and three variable length links are attached to the coupler frame, has a first end pivotally coupled to the vehicle and a second end pivotally coupled to a central part of the coupler frame. Three variable length links, each variable length link having a first end pivotally coupled to the vehicle and a second end pivotally coupled to the coupler frame. The three variable length links preferably extend generally parallel to each other and are spaced apart in a triangular array, and the fixed length link is positioned near the center of the array. The three variable length links include an upper link and left and right lower links. The three variable length links are preferably hydraulic cylinders which can be extended and retracted.
