Abstract: A conventional three point hitch of an agricultural tractor for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation is modified by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

Abstract: 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.

Abstract: An apparatus for connecting an implement to a three point hitch of mobile machinery comprises two frameworks, a first framework and a second framework. The first framework is disposed in a first plane and comprises at least two parallel, vertically-spaced apart, laterally extending rails. There are three attachments supported by the first framework for attachment to the three-point hitch. The second framework is slidable generally in the plane of the first framework and is mounted on the rails to slide laterally along the rails. At least two connectors are supported by the slidable second framework for connecting the second framework to an implement that can be pulled or pushed by the mobile machinery. A driver is connected to the first framework and connected to the second framework for driving the second framework laterally back and forth along the rails of the first framework.
