A forage harvester including a frame, a cutting arrangement and a plurality of displacement mechanisms. The cutting arrangement includes a cutting drum that is rotatable about a rotation axis with respect to the frame, and a shear bar holder configured to receive a shear bar attached thereto. Each of the displacement mechanisms including an actuator for displacing the shear bar with respect to the cutting drum and the frame. The displacement mechanisms include a sensor arrangement to measure one or more values representative of a force exerted on the shear bar and the shear bar holder when the cutting drum is rotating and cutting crops supplied to an area between the cutting drum and the shear bar.

A harvester includes a feed system operable at a feed speed and configured to feed a crop towards a blade. The blade is configured to cut the crop into crop billet and is operable at a cutting speed. The harvester further includes an optical sensor configured to generate a signal corresponding to a length of the crop billet and a control system with a processor, a memory, and a human-machine interface. The control system is configured to receive the signal and programmed to adjust one or both of the cutting speed or the feed speed based on the signal.

A chopper system for a sugarcane harvester comprises a chopper and a timing-adjustment tool. The chopper comprises a first chopper drum mounted for rotation about a first axis of rotation and comprising blades, a second chopper drum mounted for rotation about a second axis of rotation and comprising blades that cooperate with the blades of the first chopper drum to sever sugarcane stalks into billets upon rotation of the first and second chopper drums respectively about the first and second axes of rotation, and a gearbox that coordinates rotation of the first and second chopper drums relative to one another to establish a timing of operation between the blades of the first and second chopper drums. The timing-adjustment tool removably mounts to the chopper to adjust the timing of operation.

Harvesting vehicle, in particular forage harvester or combine harvester, comprising a mounting frame (10), wherein the mounting fame (10) is designed to couple an attachment to the mounting frame (10) and via the mounting frame (10) to the harvesting vehicle, and comprising a drive coupler (16) which engages with the mounting frame (10) and which is designed to form a drive connection between the attachment and the harvesting vehicle in order to transmit a drive power provided by the harvesting vehicle in the direction of the attachment, wherein the drive coupler (16) has a drive hub (17) which can be coupled to the harvesting vehicle, a coupling disk (19) which can be coupled to the attachment and a centering mandrel (22) which cooperates with the attachment, wherein the centering mandrel (22) is fixedly engaged with the coupling disk (19), a slide piece (24) which can be displaced in a translatory manner relative to the drive hub (17) is coupled fixedly in terms of rotation to the drive hub (17), and wherein the slide piece (24) is connected to the coupling disk (19) via universal joints (30, 31) such that the centering mandrel (22) can be displaced together with the coupling disk (19) and the slide piece (24) in a translatory manner relative to the drive hub (17).

A straw chopper for a combine harvester including a rotor supporting a plurality of chopping elements. A rotor housing including an inlet opening, an outlet axially aligned with the inlet opening, and at least one outlet that is axially offset from the inlet opening. A portion of the straw is conveyed tangentially to the axially-aligned outlet, whilst a further portion is conveyed from the inlet opening to the axially offset outlet(s) via a path having an axial component, for example a helical path. Guide vanes may be provided on the inside of the housing to impart an axial force upon the straw.

A chopper system for a sugarcane harvester comprises a chopper and a wear indicator. The chopper comprises a first chopper drum, a second chopper drum, and a timer. The timer has an operational configuration in which a first timer portion and a second timer portion are operatively connected to one another to coordinate rotation of the first and second chopper drums and a timing-adjustment configuration in which the first and second timer portions are operatively disconnected from one another allowing relative movement between the first and second timer portions and corresponding relative rotation between the first and second chopper drums to adjust a timing of operation between blades of the first and second chopper drums. The wear indicator indicates an extent of blade wear of the chopper upon adjustment of the timing of operation via the timer in the timing-adjustment configuration.

An arrangement for data recording and sampling for an agricultural machine includes a sensor set-up arrangement to detect properties contained in a material stream, means of taking a sample of the material from the material stream, and an electronic control unit. The control unit is configured to perform the following steps in response to a tripping signal: (a) instruct an actuator to bring the means into a position for sampling; (b) starting a recording of raw sensor arrangement data in a memory; (c) after depositing the sample at a desired sampling location, stop recording the raw data and instruct the actuator to return the means from the sampling position to an inactive position; and (d) store identification data to identify the sample together with the raw data in memory.

A mower (1) comprising: a blade (9) that mows grass; a power generation unit (5) that generates a driving force for rotating the blade (9); a housing (7) that covers the blade (9); and a milling unit (10) that subdivides grass mowed by the blade and discharged from the housing (7).
