A cutting assembly includes: a rotor having extensions; a rotor floor disposed adjacent to the rotor and having knife slots formed therein, the rotor floor defining a cutting side and a shielded side on the opposite side of the rotor floor; movable knives that each extend through a respective knife slot into the cutting side to cooperate with the extensions in a cutting position and are disposed on the shielded side such that the knives do not cooperate with the extensions in a retracted position; and a knife guide including a pair of spaced apart guide surfaces coupled to the rotor floor on the shielded side and defining a gap therebetween. A respectively associated knife is at least partially disposed in the gap when in the retracted position. At least one of the guide surfaces defines a curved shape that corresponds to a cutting edge profile of the associated knife.

A cutting device for agricultural harvesters has a conveying channel and pivotably supported cutting knives arranged in a row on a frame. The cutting knives project in the cutting position into the conveying channel. A conveying member with conveying tines, rotatingly driven about a horizontal axis, interacts with the cutting knives for comminuting crop. Individual adjusting devices, each associated with one cutting knife, yieldingly support the cutting knives in the cutting position. A knife switching device is provided to move the cutting knives from the inoperative position into the cutting position. With a preselecting device a desired group of cutting knives can be selected that is pivoted into the cutting position upon activation of the knife switching device. The preselecting device is activatable with reduced force expenditure by eliminating resistances, caused by adjusting and connecting devices of the knife switching device, when preselecting the desired group of cutting knives.

A wear plate assembly for an agricultural harvester including a support element having a number of lateral regions, each lateral region being provided with a plurality of first engagement features, one or more replaceable wear plates provided on one side with a plurality of second engagement features for engagement with the first engagement features, and a plurality of fastenings to secure each replaceable wear plate to the support through the engagement features.

A chopper drum assembly for a forage harvester including a chopper drum housing, a shear bar, a shear bar holder and a wear plate assembly. The chopper drum housing includes a first part and a wear plate assembly support surface. The shear bar holder is pivotally connected at a first end to the first part of the chopper drum housing and fixedly connected to the shear bar at a second end. A first end of the wear plate assembly is pivotally connected to the second end of the shear bar holder adjacent the shear bar, and a second end of the wear plate assembly is supported by the wear plate assembly support surface wherein, the wear plate support surface is arranged to be inclined to the horizontal.

A chopper for an agricultural harvester comprises a housing, a rotor, a bank of counter-knives, and an adjuster. The housing comprises a variable geometry outlet floor. The is positioned in an interior region of the housing for rotation therein relative to the housing. The bank of counter-knives is movable relative to the rotor between a first aggressiveness position and a second aggressiveness position to adjust chopping aggressiveness of the chopper. The outlet floor comprises a ramp movable relative to the rotor between a first ramp position and a second ramp position. The adjuster positions the ramp in the first ramp position when the bank of counter-knives is positioned in the first aggressiveness position and positions the ramp in the second ramp position when the bank of counter-knives is positioned in the second aggressiveness position.

The automatic, rotating agricultural system rotates around a central pivot point in either a full rotation or a partial arc to irrigate, plant and/or harvest a field. The agricultural system includes a center pivot frame, a plurality of frame segments connected to each other, and a feed storage bin connected to the center pivot frame and the frame segments. The frame segment includes a section frame including wheels to enable movements, a cutter trolley beam extends in a radial direction of the section frame, a cutterhead coupled to the cutter trolley beam to cut forage or crop, a radial conveyor that moves the cut forage or crop in the radial direction of the section frame, and a cutter conveyor that moves the cut forage or crop from the cutterhead to the radial conveyor.

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.

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 system for harvesting a forage crop material, includes: a first agricultural work equipment for controllably harvesting the forage crop material, the first agricultural work equipment including: a first forage processing assembly; a first control system including: a first forage processing assembly condition sensor configured for sensing a first actual condition of the first forage processing assembly and thereby for outputting a first actual condition signal associated with the first actual condition of the first forage processing assembly; a first controller operatively coupled with the first forage processing assembly condition sensor and the first forage processing assembly and configured for: receiving the first actual condition signal; determining a first adjustment signal based at least in part on the first actual condition signal and at least one first predicted forage crop material condition associated with a first forage processing operation; outputting the first adjustment signal and thereby for initially adjusting, prior to beginning the first forage processing operation, a first device of the first forage processing assembly.
