Chopping unit (5) of an agricultural harvesting machine (1), having a chopping drum (10) bearing chopping knives, a first roller pair (11) consisting of an upper and a lower press roller (15) and (16) positioned upstream of the chopping drum (10), at least one second roller pair (12) consisting of a pre-compression roller (13) and a transport roller (14) positioned upstream of the first roller pair (11), a counter-cutting device (18) cooperating with the chopping drum (10) and a stripper device (19) cooperating with the lower press roller (16), arranged between the lower press roller (16) and the chopping drum (10), wherein a rotary shaft (20) of the lower press roller (16) and/or a rotary shaft (21) of the transport roller (14) can be displaced in its relative position to a rotary shaft (17) of the chopping drum (10) at least in the vertical direction.

A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.

An agricultural baler includes a baling chamber and a pre-compression chamber. The pre-compression chamber is configured to gather crop material and to periodically form a slice of the crop material and introduce the slice into the baling chamber. The baling chamber includes a plunger provided for moving in the baling chamber thereby compressing slices of crop material into a bale. The agricultural baler further includes multiple sensors and a controller configured for controlling operation of the agricultural baler based on inputs of the multiple sensors. A first subset of the multiple sensors is directly related to bale parameters, and a second subset of the multiple sensors is indirectly related to the bale parameters. The controller is configured to control the operation of the agricultural baler and calibrate the sensors of the second subset based on outputs of sensors of the first subset.

A monitoring system for a combine harvester having a header with a header width for harvesting a crop. The monitoring system includes a plurality of sensors, configured to provide a plurality of measurement waves to a discharge area for crop residue, and receive a plurality of response waves reflected from the discharge area. The system further includes a processing unit comprising an input terminal configured to receive a response signal of the plurality of sensors, the response signal representative of the plurality of response waves reflected from the discharge area. The processing unit is configured to process the response signal and determine, based on the response signal, a distribution of the crop residue over the discharge area. The processing unit further comprises an output terminal configured to output a distribution signal representative of the distribution of the crop residue over the discharge area.

An adjustment apparatus for a forage harvester having a shear bar adjustably mounted on a housing. A chopper drum is supported from the housing and mounted for rotation about an axis and further provided with a plurality of circumferentially spaced knife supports to which at least one chopper knife can be adjustably secured. In use the chopper knives cooperate with the shear bar to chop incoming crop. The adjustment apparatus includes a lateral element, at least one location element and at least one radially inwardly directed guide surface. The adjustment apparatus also includes at least one shear bar alignment surface on one or more of the location elements.

A knife and blade for agricultural machines, in particular mower knife blades, straw chopper knives, corn header knives, feed mixer knives, loader wagon knives and baler knives, has at least one toothed cutting edge extending from a cutting edge beginning to a cutting edge end on a blade surface. The cutting edge has a straight or curved configuration and the blade surface has a mounting section. The toothing of the cutting edge is varied along its length with regard to the tooth pitch and/or the tooth geometry.

An agricultural cutting blade has top and bottom surfaces and mounting apertures extending through top and bottom surfaces. A cutting edge support surface (e.g. that may be a flat, pointed or rounded) is formed on the cutting blade body with the cutting edge support extending along a side of the cutting blade body transversely between the top and bottom surfaces. A clad material deposited upon the cutting edge support such as by laser cladding process. The clad material can be built up, that is layered in partial or full overlapping relation to provide at least 2 and often more than 4 layers of clad material at one or more locations. A cutting edge provided by the clad material that may be a ground surface into a laser clad bead.
