A working vehicle comprises a vehicle body, a quick hitch, a working implement connected to the vehicle body via the quick hitch, and a linkage interposed between the quick hitch and the vehicle body. The linkage is movable to raise and lower the quick hitch so as to locate the quick hitch at an optional height. The quick hitch can be inclined to a certain degree in a pitching direction of the vehicle body at the optional height defined by the linkage.

An adjustable three point hitch system includes a frame that may be removably coupled to a tractor. The frame has a selectively adjustable width. Thus, the frame may be coupled to implements having a variety of widths thereby facilitating the tractor to draw the implements. A spreading unit is coupled to the frame and the spreading unit may be manipulated. The spreading unit urges the frame between a minimum width and a maximum width.

A quick joint of a front loader, the quick joint includes: a coupling member (30) having a hook shape and pivotally connected to a first pivot point (P1) of a boom post (20) through a first pivot shaft (31); a spring member (32) for applying an elastic force in a direction of releasing the coupling member (30) from a coupling target shaft (14) disposed on a boom post support (10) which is attached to a tractor (1); a lock unit (34) having a part making contact with the coupling member (30), and provided with a lock pin (36) for restraining behavior of the coupling member (30) at a coupling position (A1); and a guide slot (38) having an arc shape and formed in the boom post (20) to define a moving path of the lock pin (36) when the lock unit (34) rotates.

A hitch for connecting an implement to a vehicle. The hitch comprises a first frame for attachment to the vehicle and a second frame for attachment to the implement. The hitch further comprises connection means between the first frame and the second frame for connecting the implement to the vehicle when the first frame is attached to the vehicle and the second frame is attached to the implement.

Provided is a pick-up hitch assembly for connection to a vehicle. The pick-up hitch assembly includes a swing frame having a first end configured to be coupled to the vehicle and a second end, a slide frame movable relative to the swing frame between a retracted position and an extended position, and an electrically powered actuator assembly configured to be coupled to the vehicle and being coupled to the swing frame at the second end of the swing frame. The actuator assembly is configured to move the swing frame between a raised position and a lowered position independent of movement of the slide frame and of a three-point hitch.

A quick coupler for a three-point hitch includes a cross-beam configured to extend between a first main support and a second main support. The cross-beam is configured to support an anti-rotation hook. In addition, the cross-beam includes a top member extending along a length of the cross-beam and a bottom member extending along the length of the cross-beam. The top member and the bottom member are spaced apart to form a hollow portion between the top member and the bottom member. Furthermore, the cross-beam includes at least one cross-member extending from the bottom member to the top member within the hollow portion.

One or more techniques and/or systems are disclosed for adjusting the downward vertical force applied to the vehicle frame. In this way, an operator can adjust or distribute a vertical downward force that an attached implement applies to the frame of a vehicle towing the implement. A front end of a vertical load member can be pivotably coupled to the vehicle frame at a point in front of the rear axle of the vehicle, and a rear end of the vertical load member can be coupled to a hitch attachment assembly, coupled with a towed implement, at a rear end of the vertical load member. An actuator can be pivotably coupled with the vertical load member rearward of the vehicle axle, and to the vehicle frame. The vertical load member can be raised and lowered using the actuator, which raises and lowers the hitch assembly at the rear, and pivots the vertical load member at the front.

A system is suitable for connecting multiple implements to a three-point hitch of mobile machinery for controllable side-shifting movement of the connected implements. The system comprises first, second and third apparatuses, each apparatus comprising a first framework, a slidable second framework laterally slideable relative to the first framework, at least one connector supported by the slidable second framework for connecting the slidable second framework to one of the implements, and at least one driver connected to the first framework and the slidable second framework for driving the slidable second framework laterally back and forth relative to the first framework. The second apparatus is attached to one side of the first apparatus and the third apparatus is attached to the other side of the first apparatus.

An attachment assembly for connecting an agricultural implement to a tractor. The attachment assembly comprises a tractor-side frame configured to extend from a rear of the tractor, and an implement-side frame configured to be removably attached to the implement. The implement-side frame is configured to rotate with respect to the tractor-side frame.

A mechanical system attaches to a tractor and, upon activation of a hydraulic ram, rotates implement-engaging implement lift hooks to rotate an attached agricultural implement upwards towards 90 degrees for inspection and maintenance. The system can be secured in its raised and rotated position via a locking pin. The implement is returned to its original position through removal of the locking pin, reversal of the hydraulic ram and disconnection of the implement lift hooks.
