摘要： A mower has a plurality of rotary cutters for cutting a crop and a swathing unit for forming a cut crop into a swath. In some embodiments, the swathing unit includes an auger and a housing that extends around at least part of the auger and provides a swathing aperture through which cut crop material is ejected to form a swath. In some embodiments, the housing includes at least one guide plate that can be adjusted to adjust the width W of the swathing aperture.

摘要： A rotary cutter unit (6) for an agricultural mower (2) comprises a housing (14) that carries a rotary bearing (18) having an axis of rotation (X), and a rotor assembly (20) that is supported by the bearing for rotation relative to the housing about the axis of rotation. The rotor assembly includes a shaft (24) that extends through the bearing, a drive input element (28) at an input end of the shaft for transmitting rotary drive to the shaft and a drive output element (32) at an output end (22) of the shaft to receive rotary drive from the shaft. A frangible element (40) comprising a weakened portion of the shaft (24) is provided between the drive input element and the drive output element, which is configured to break when subjected to an excessive load so as to interrupt the transmission of rotary drive between the drive input element and the drive output element. A retention mechanism (44) is provided, which prevents separation of the drive output element from the housing when the frangible element breaks but permits rotation of the drive output element relative to the housing. The retention mechanism includes a retention element (46, 48) that extends substantially radially between the drive output element (32) and the housing (14) to restrict axial movement between the drive output element and the housing.

摘要： An agricultural implement is described comprising a chassis, a rotor mounted thereon that is rotatable about an upright axis and comprises working tools, a hydraulic lifting device for raising the chassis between a work position and a transport position, and an adjustment mechanism for adjusting the height of the rotor for the work position. The lifting device is arranged underneath the rotor and is connected to a hydraulic line that is run from top to bottom through the rotor. The adjustment mechanism comprising a tubular actuating element surrounding the hydraulic line or forming sections thereof with at least one axial adjustment thread mutually supporting the rotor and the chassis and an operating device arranged above the rotor for axially turning the actuating element.

摘要： An agricultural machine (2) comprises an operating unit (6) and a carrier assembly (8) for the operating unit. The carrier assembly (8) includes a carrier arm (12) and a suspension system (16) by which the operating unit (6) is suspended from the carrier arm (12). The suspension system (16) including two pairs of connecting rods, comprising a pair of upper connecting rods (28) and a pair of lower connecting rods (30), each said connecting rod being attached via joints (32) to the operating unit (6) and the carrier arm (12). A first pair (30) of said upper and lower connecting rods diverge in a working direction of the operating unit and a second pair (28) and of said upper and lower connecting rods converge in a working direction of the operating unit.
