Abstract: 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.

Abstract: An agricultural machine comprises an operating unit and a carrier assembly for the operating unit. The carrier assembly includes a carrier arm and a suspension system that suspends the operating unit from its center point and allows the operating unit to rotate about an axis that extends in the working direction. A support mechanism supports the weight of the operating unit and allows the height of the operating unit arm to change. The support mechanism includes an actuator located on the axis of the operating unit and configured to adjust the height of the operating unit.

Abstract: 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.

Abstract: An agricultural machine can include a plant processing apparatus for processing plant material. The plant processing apparatus includes a cylindrical drum rotatable about a drum axis, a rotary drive for rotating the drum about the drum axis, and a curved shell that extends around at least part of the circumference of the drum. The plant processing apparatus includes a processing channel provided between an outer surface of the cylindrical drum and an inner surface of the shell. The processing channel has an inlet end and an outlet end. Plant material is transported through the processing channel from the inlet end to the outlet end by rotation of the cylindrical drum. The drum and the shell each have sets of working elements that together process the plant material as it is fed through the processing channel.

Abstract: 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.

Abstract: A plain mower includes a plurality of rotary cutters for cutting a crop and a swathing unit for forming the cut crop material into a swath. The swathing unit includes an auger that rotates about an axis to transport crop material axially through the swathing unit. The swathing unit can be configured in a first configuration in which the crop material is ejected axially from the auger, and can be reconfigured in a second configuration in which the crop material is ejected radially from the auger.
