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.

Provided is an earth conditioning system/apparatus which removes/break-ups rock in the ground and has a front drawbar, a ground engaging tool arrangement and a rear rotary device (drum). A ground engaging tool arrangement includes a frame supporting ground engaging tools each mounted at a pivot. Actuators raise/lower the ground engaging tool(s) for desired depth control of the ground engaging tools. The rotary device slotted or ribbed drum acts as a crushing drum rolled over earth that has been broken up by the ground engaging tools. Actuators, provide height adjustment of the ground engaging tools relative to the ground engaging tool support frame and by adjusting the height from the ground of the ground engaging tool arrangement by operating the at least one adjuster acting between the rotary device and the ground engaging tool arrangement.

In one aspect, a method is disclosed for automatically controlling a position of an implement of an agricultural work vehicle relative to a ground surface. The method may include monitoring, with one or more computing devices, an implement position parameter indicative of the position of the implement relative to the ground surface. The method may also include calculating a normal output signal based on the implement position parameter. The method may also include determining when a boost condition is satisfied based on a comparison between the implement position parameter and a predetermined implement position parameter threshold. The method may also include computing a boost output signal based on the implement position parameter. The method may also include adjusting the position of the implement relative to the ground surface based on the normal output signal and the boost output signal.

A method for determining a physical parameter of an adjustable upper link of a three-point hitch during a working operation thereof includes providing a lower link of the three-point hitch and an implement attachable to the upper and lower links of the three-point hitch. The method includes generating calibration data prior to the working operation of the three-point hitch, where the calibration data defines a relationship of a length of the upper link to an upper link angle defined between the upper link and a reference line. Moreover, the calibration data is used to determine a physical parameter of the adjustable upper link during the working operation.

In one aspect, a system for monitoring the condition of seedbed within a field may include a plurality of ground-penetrating tools supported by an implement frame adjacent to its forward end. The system may also include a plurality of surface-finishing tools supported by the implement frame adjacent to its aft end. Moreover, the system may include a seedbed floor detection assembly coupled to the implement frame behind the plurality of ground-penetrating tools and in front of the plurality of surface-finishing tools. The seedbed floor detection assembly may include a seedbed tool configured to ride along the seedbed floor. Additionally, the seedbed detection assembly may include a seedbed floor sensor configured to detect a position of the seedbed tool relative to the implement frame, with such position being indicative of variations in a profile of the seedbed floor.
