Abstract: A chopper blade for use in an agricultural harvester chopper to chop crop residue comprises a blade body and a hard face. The blade body comprises a cutting edge of the chopper blade. The hard face is applied on a surface of the blade body, and is harder than the blade body. The hard face comprises a serration pattern along a cutting edge such that the cutting edge wears to the serration pattern to match the serration pattern to form corresponding serrations in the cutting edge with the serration pattern becoming part of the cutting edge of the chopper blade during use of the chopper blade.

Abstract: A chopping assembly is configured to receive crop plants processed by an agricultural combine harvester. The chopping assembly includes an inlet and a plurality of blades rotatable about an axis. The plurality of blades is positioned downstream of the inlet. The chopping assembly also includes an outlet positioned downstream of the plurality of blades. The outlet is partially defined by a first wall and a second wall. The chopping assembly further includes an actuator coupled to the second wall. The actuator is configured to move the second wall relative to the first wall. A control processor is in communication with the actuator. The control processor is configured to receive a first signal corresponding to a condition representative of a characteristic of the crop plants. The control processor is also configured to generate a second signal operable to control the actuator based on the condition.

Abstract: A plastic filler for a cylinder conveyor, wherein the cylindrical conveyor includes a drum supported on a central shaft and defines a void therebetween, and wherein the plastic filler at least partially fills the void and thereby prevents the entry of contaminants into the void.
