The disclosure refers to an agricultural apparatus for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field, which may comprise: a frame, crop engaging elements supported on the frame and configured to form from previously-cut agricultural crop a windrow on a field, and a control unit configured to control operation of the crop engaging elements. The control unit is further configured to provide control signals to the crop engaging elements in such a way that, in a windrow forming mode of operation, the crop engaging elements are driven to engage with the previously-cut agricultural crop, and form from the previously-cut agricultural crop the windrow which may have a snake line form on the field. Further, a method for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field is also disclosed.

An agricultural machine including a frame, at least one operating unit connected to the frame, at least one wheel or crawler track rotatably attached to the frame to allow the movement of the machine on a supporting surface and a lifting unit operatively interposed between the frame and the wheel or between the frame and the operating unit, configured to vary the height of the operating unit with respect to the supporting surface of the machine. The lifting unit includes at least one hydraulic cylinder provided with a liner, a first and a second piston both slidingly housed inside the liner and arranged in series to define at least a first and a second chamber inside the liner, wherein the first and the second piston can be controlled independently of each other.

A swather includes a frame, a chassis which supports the frame, at least one processing member which is connected at least indirectly to the frame, a front coupling device which is arranged at a front side of the frame with respect to a longitudinal axis of the swather, and a rear coupling device which is arranged at a rear side of the frame with respect to the longitudinal axis. The at least one processing member grips a crop material. The front coupling device defines a front coupling point for attaching the swather to a tractor. The rear coupling device defines a rear coupling point for attaching a baler to the swather.

A haymaking machine for tedding or raking agricultural stalk or leaf material includes a tedding or raking rotor arranged on a machine beam. The tedding or raking rotor is rotated about a vertical axis when working/operating. The tedding or raking rotor includes two tine arms aligned approximately radially which are uniformly distributed in a circumferential direction about the vertical axis, a first spring tine having a first length arranged on the two tine arms, a second spring tine having a second length arranged on the at least two tine arms, a first measuring device which interacts with the first spring tine, and a second measuring device which interacts with the second spring tine. The second length is smaller than the first length. The first measuring device measures a force acting on the first spring tine. The second measuring device measures a force acting on the second spring tine.

A haymaking machine includes a frame, a turning or raking rotor and a sensor arranged on the frame, and a control device. In a working position, the turning or raking rotor is drivable relative to the frame about an axis of rotation in a direction of rotation. The turning or raking rotor has tine arms which have tines. The tine arms are aligned at least temporarily to face the ground. The tine arms are arranged uniformly distributed in a circumferential direction around the axis of rotation and are aligned in an approximately radial direction with respect to the axis of rotation. The sensor continuously detects a passing of the tine arms during an operation of the turning or raking rotor and transmits a measurement signal thereof. The control device receives the measurement signal and infers an operating state of the at least one turning or raking rotor based thereon.

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.

An agricultural machine includes: a work tool, a coupling frame including a crossing beam and two levers, each lever carrying a respective hitching point attached to a respective lower arm of the tractor and being able to move vertically relative to the crossing beam, each lever having an associated restoring device which can exert a force on the associated lever when the respective hitching point moves vertically relative to the crossing beam. The machine is able to occupy a work configuration in which the tool is close to the surface and a transport configuration, in which the tool is further away from the surface. Each restoring device includes a hydraulic restoring jack fixed to the respective lever on one side and to the crossing beam on another side, each restoring jack being hydraulically connected to a hydraulic tank in the work configuration.

A system includes an agricultural raking vehicle, including a motor drive and raking members mechanically coupled to the motor drive. The raking members rake agricultural product via rotation about an axis substantially orthogonal to a field on which the agricultural vehicle travels. The system also includes a sensor assembly that outputs a signal indicative of a determined windrow quality of the agricultural product raked by the raking members. The system also includes a controller communicatively coupled to the motor drive and to the sensor assembly. The controller receives the signal and controls an angular speed of the motor drive, a ground speed of the agricultural vehicle, and/or a height of the raking members or tines above the field, based on a comparison of the determined windrow quality to a target windrow quality.

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.
