A towed agricultural implement includes one or more processing units each supported on a chassis, in which each chassis supports at least one processing unit on a central axis, the chassis having a left hand side wheel assembly support and a right hand side wheel assembly support, free ends of the wheel assembly supports having wheel assemblies, each wheel assembly comprising a wheel mounted on a wheel mount, the wheel mount being rotatable about an inclined axis, and the wheel being rotatable about a horizontal axis. The wheel assembly supporting structures and the wheel mounts allow limited relative movement of each wheel mount with respect to the wheel assembly supporting structures which enables greater control when the towed agricultural implement is towed about a corner.

An agricultural implement including a frame, at least one rake moveably coupled to the frame and including a plurality of tine arms, a plurality of tines connected to the plurality of tine arms, and a rotor drive configured for rotating the plurality of tine arms, and an adjustment system configured for adjusting a rake height of the at least one rake. The adjustment system includes at least one actuator, an electronic control unit operably connected to the at least one actuator, and at least one dust sensor supported by the frame and operably connected to the electronic control unit. The at least one dust sensor monitors a dust level and communicates dust level data to the electronic control unit which correspondingly adjusts the rake height based upon the dust level data.

An agricultural machine for processing cut plants to be moved in a progression's direction, the machine includes a chassis fitted with a hitching device enabling it to be hitched to the tractor vehicle, multiple rotors equipped with raking teeth that can be driven in rotation around substantially vertical driving axes distributed on either side of a median plane passing through the chassis. Each outer rotor and the penultimate rotor adjacent to it, driven in opposite rotational directions, form a module of which a longitudinal plane contains the driving axis of the outer rotor and the driving axis of the penultimate rotor, and, in work configuration, the longitudinal plane of a first module forms, together with the median plane, an acute work angle that is open to the rear, and the longitudinal plane of a second module forms an acute work angle with the median plane open to the rear.

A suspension mechanism for a rotary rake implement incorporates elastomeric shock absorbing members in the corners of a tubular member situated in between the corners of a square rod formed as part of the wheel assembly and received within the tubular member such that the corners of the square rod assert a pre-load spring force on the tubular member when the implement is in an extended operating configuration. The movement of the implement into a folded transport configuration with the weight of the implement supported on the transport wheel assemblies causes a deflection of the square rod that compresses the elastomeric shock absorbing members within the corners of the tubular member to provide maximum suspension for the implement when in transport, while providing minimum suspension when the implement is in operation. An end cap on the square rod engages a stop formed on the tubular member to control rotation.

A wheel mounting structure for a towed agricultural implement having a support beam and a plurality of wheels. The wheels are mounted to the support beam to be displaceable with respect to the support beam between a first position in a transport position and a second position displaced from the first position away from the support beam in a working position. This has as an advantage that the framework is displaced to increase a ground clearance when the towed agricultural implement is in the working position.

An agricultural system comprising: an agricultural rake for a raking operation comprising gathering cut crop material into a windrow, the agricultural rake comprising: a crop condition sensor positioned on the agricultural rake to detect a condition of the cut-crop material prior to, during, and/or after, windrow formation; wherein the agricultural system further comprises: a controller configured to: receive crop condition data from the crop condition sensor; determine a process parameter for a subsequent agricultural process to the raking operation, based on the crop condition data; and output the process parameter.

The invention relates to a method (100) for operating an agricultural machine (1, 201) on a useful agricultural area (4, 5), comprising a traction vehicle (2) and a working appliance combination (3, 203) connected to the traction vehicle (2) in the form of a mower and/or rake, the harvest goods being processed with a plurality of working devices (33a-33d, 233a-233c), which are arranged so as to project from a carrying frame (31, 231a-231b) transversely with respect to the direction of travel (F) of the working device combination (3, 203), wherein the working appliances (33a-33d, 233a-233c) can each be raised and lowered independently of one another in order to move the working appliances either into a headland position or into engagement with the harvest goods, characterized in that when processing by means of a preferably satellite-assisted navigation system (21), position data of the working device combination (3, 203) is acquired continuously and, from the same, at least one already processed field area (41, 51) is determined and recorded (112), and in that the working devices (33a-33d, 233a-233c) are each raised automatically (113) on the basis of their positions when reaching the at least one already processed field area (41, 15) again, and/or in that the working devices (33a-33d, 233a-233c) are each automatically lowered (114) on the basis of their positions when moving out of the at least one already processed field area (41, 51 into a field area (42, 52) that is still to be processed.

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.
