Abstract: A towed agricultural implement including a first headstock element for connection to a towing vehicle, a second headstock element supporting a chassis member provided with a plurality of working implements, a pivot pin for connecting the first headstock member and the second headstock member and defining a horizontal axis of rotation between the first headstock member and the second headstock member, in which the second headstock member has a lateral centre of gravity offset from the axis of rotation. A compensating structure is provided between the first headstock member and the second headstock member to offset the unbalanced loads caused by the lateral centre of gravity being offset from the axis of rotation.

Abstract: 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.

Abstract: An agricultural tool including an elongated frame, ground engaging wheels for supporting the frame, and at least two rotors carried by a respective arm. Each respective arm is moveable into a working position in which the rotors are carried on opposing sides of the frame at a distance away from the frame. Each rotor includes a hub provided with tines and each hub is supported above the ground by at least one support wheel. The tool further includes a control system which detects when the tool is moving around a bend and identifies which of the rotors is an inner rotor moving on the inside of the bend and raises the inner rotor to compensate for the downward force exerted on the inner rotor during the turn.
