Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar and for folding a toolbar between a field position and a transport position.

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.

An agricultural implement includes a transversely extending frame forming a first, a second, and a third frame section. A first actuator is coupled to the first frame section, a second actuator coupled to the second frame section, and a third actuator coupled to the third frame section. Sensors are coupled to each frame section to detect a height of the respective frame section relative to an underlying surface. A control unit is disposed in electrical communication with the sensors and operably controls the actuators to adjust the height of each frame section.

In one embodiment, an agricultural system includes a tool bar configured to couple to a tow vehicle. The tool bar is configured to support at least one row unit assembly. The agricultural system also includes a lift assist assembly coupled to the tool bar such that rotation of the tool bar relative to the lift assist assembly about a vertical axis is blocked. The lift assist assembly is configured to provide lifting support to the tool bar. The lift assist assembly comprises a frame, one or more rolling elements configured to contact a surface of a field, and one or more telescoping members configured to adjust a configuration of the lift assist assembly along at least one of a lateral axis, a longitudinal axis, and the vertical axis.

A towed soil cultivation implement (1) is proposed in which the soil tillage tools (5) are guided by a contact pressure controlled depth guide device (9), which enables a constant weight load on a downstream, adjustable reconsolidation implement (6) on uneven ground as well. In the process, the pull line between tractor (3) and soil cultivation implement (1) are maintained in an optimum position.

An agricultural tillage implement for use in a field. The agricultural tillage implement including a frame section and a plurality of wing sections. The frame section has a pull hitch extending in a travel direction. Each of the plurality of wing sections are coupled to the frame section and/or a wing section. The wing sections each have an articulated portion pivotal about an axis substantially perpendicular to the travel direction.

A towed agricultural working tool with a central frame element, a headstock and left and right hand side frame elements connected to the central frame element, each of the side elements supporting at least one processing unit, the central frame element being connected at, at least one connecting location for pivoting movement with respect to the headstock in which one or more friction elements are arranged between the central frame element and the headstock at one of the at least one connecting locations. This has as an advantage that the pivoting movement of the central frame with respect to the headstock, in particular due to induced yaw, is reduced.
