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.

A quick disassembly tool for fixedly mounting a connection module is provided according to the present application, including a pressing block and a fixing block for press-fitting the connection module. A press-fitting end face of the fixing block is provided with a press-fitting hole, and a press-fitting post inserted into the press-fitting hole protrudes from the pressing block; the quick disassembly tool further includes a locking device respectively pressing on an end of the pressing block and an end of the fixing block, and the locking device includes an elastic pressing device configured to adjust a press-fitting space between the pressing block and the fixing block. The pressing block and the fixing block are connected and transversely position-limited through the press-fitting hole and the press-fitting post, the locking of the pressing block and the fixing block in a pressing direction is achieved by a locking device.

A data processor determines whether a draft force on the implement is unbalanced based on an error between the observed implement angle and a target implement heading exceeding a threshold deviation. The data processor is adapted to generate a control signal to compensate for the imbalance in the draft force by adjusting the first lateral position via the first actuator, or by adjusting the second lateral position via the second actuator, the first actuator and the second actuator being positioned on opposite lateral sides of the implement.

A method is carried-out by a controller architecture coupled to a beam assembly actuator, which is included in an articulating tongue arrangement connecting an agricultural implement to a tow vehicle. In an embodiment, the method includes: (i) monitoring, via the controller architecture, an effective tow length of an articulating beam assembly further included in the articulating tongue arrangement, the effective tow length measured along a straight line extending from a leading pivot joint of the articulating tongue arrangement to a trailing pivot joint of the articulating tongue arrangement; (ii) determining, at the controller architecture, an effective tow length target of the articulating tongue arrangement based upon operator input, sensor input, or a combination thereof; and (iii) transmitting commands from the controller architecture to the beam assembly actuator to maintain the effective tow length of the articulating beam assembly in conformance with the effective tow length target.

A tractor control system, which controls an operating condition of an implement attached to the tractor. The control system includes a sensing means providing a force signal which indicates the pull force necessary to pull an implement in a desired position; a control which receives the force signal; and means for measuring at least one parameter associated with the tractor mode and/or the implement mode and the implement position is adjusted to a new position when the force signal varies. The control system includes pre-determined values associated with certain tractor and/or implement modes. A measured parameter is compared with a pre-determined parameter value and if the measured parameter would result in an undesired movement of the implement, the force signal is deactivated, or the response to the force signal is deactivated to prevent undesired movement of the attachment.
