A towed agricultural implement including a support frame, with one end adapted for connection to a towing vehicle, a drive apparatus carried by the support frame, with one end of the drive adapted for connection to the towing vehicle, support arms carried from the support frame, where each of the support arms are moveable between a working position and a transport position, and each support arm includes at least one rotary rake adapted to be driven about a central rake axis, a drive arrangement connecting the rotary rake to the drive apparatus, and an intermediate drive element connecting the drive apparatus and the drive arrangement moveably supported from the support frame to ensure that a sufficient overall length is available for the displaceable arm drive arrangement in the transport position.

An agricultural implement includes a main frame attachable to a towing vehicle, a wheel support supporting the main frame and having main wheels, and a lifting unit configured to bring the agricultural implement into one of a transport position, a working position, or a headland position. The wheel support and the tedder frame are each pivotable around a common axle on the main frame, the lifting unit includes an adjustment assembly attached to the wheel support at a first attachment point and to the tedder frame at a second attachment point, the first attachment point and the second attachment point span the common axle and form a triangle therewith, and the lifting unit is configured to pivot the tedder frame and the wheel support around the common axle to bring the agricultural implement into a predetermined position between and including the working position and the headland position.

A haymaking machine has a rake rotor with frame and support arm provided with a base part and a sliding part. The base part is pivotably connected to the frame about a support arm axis to enable the support arm to pivot between a lowered active position and a raised passive position. The sliding part is slidable relative to the base part between an inner position and an outer position for length adjustment of the support arm. The outer position is farther removed from the support arm axis than the inner position. A catching element is connected to the sliding part. A linear drive is connected to frame and sliding part to move the sliding part into the inner position and pivot the support arm from active position into passive position. A retaining mechanism holds the support arm in active position until the sliding part has reached the inner position.

The present invention relates to an agricultural haymaking machine comprising a chassis resting on the ground by at least one wheel and intended to be coupled to a tractor able to move the machine in a direction of advance, a carrier carrying a plurality of rotors being swivel mounted to the chassis around a central pin oriented transversally to the direction of advance, each rotor being driven around a respective drive axis, and a lift actuator, articulated to the chassis on one hand and to the carrier on another hand, being able to make the carrier pivot around the central pin relative to the chassis, the machine being able to adopt a headland configuration in which the carrier is raised, as well as a work configuration in which the carrier rests on the ground by means of at least one support. The central pin is rigidly attached to the carrier, and the machine comprises a positioning actuator able to move the central pin relative to the chassis to change the position of the drive axes relative to the ground.

The present invention provides provide adjustable dual rotary raking machines in which the lateral positions of the rotors and rakes may be moved while in use without stopping operation. The present invention also provides adjustable dual rotary raking machines which are suitable for collecting prunings from agricultural orchards or vineyards having low hanging branches. The present invention further provides adjustable dual rotary raking machines which may be easily collapsed for storage and transport into a small profile that allows multiple options for storing the machines, and does not require special permits to transport the collapsed machines on public roads.

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.

A float arm support system may include a float arm supporting an active member, the float arm being pivotable about a first axis, a skid shoe to bear against and follow local ground contours of the underlying terrain while supporting the active member of the float arm above the underlying terrain and a powered actuator. The skid shoe may be coupled to the float arm between the first axis and the active member. The powered actuator may be operably coupled to the skid shoe to vertically move the skid shoe to adjust a spacing at which the skid shoe supports the active member of the float arm relative to the underlying terrain.

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.
