Definition
The Restrictor plate (grater) 810860.0 is a genuine OEM wear part installed within the pre-chamber or feed channel of a Claas baler. It is a hardened steel plate, often featuring a perforated or grated surface, that acts as a controlled constriction for the crop flow entering the bale chamber.
Function and Role
This component’s primary role is to manage and condition the crop mat to ensure the formation of a dense, uniform bale. Its specific functions are:
-
Crop Compression and Pre-Densification: The plate creates a narrow opening that the crop must be forced through. This action initiates the compression process, squeezing out air and starting to form a compact mat of material before it reaches the main plunger.
-
Flow Regulation and Even Distribution: By restricting the flow, it prevents the crop from entering the bale chamber in an uncontrolled, loose clump. This promotes an even distribution of material across the entire width of the chamber, which is critical for forming a bale with straight sides and consistent density.
-
Foreign Object Protection: The robust, grated design can help break up minor clumps and allow some fine debris to fall away. More importantly, its strength helps shield the more sensitive components of the main plunger and knotter system from the impact of larger, harder objects that may be in the crop.
