Why is there foreign material in the clean grain of my AGCO Farm Equipment?
- TTommy KochAug 21, 2025
Foreign material in clean grain may be caused by several factors. The engine may not be running at the correct speed, so adjust the engine high idle to the proper speed. Check for slipping belts in the separator drive, fan drive, or cleaning shoe drive; inspect the drives, replace any damaged belts, and adjust idlers as needed. Ensure the fan inlet screen is clean and properly installed. Other causes include uneven feed to the cylinder, insufficient material entering the cylinder, using the incorrect chaffer for the crop, insufficient air blast from the cleaning fan (increase the fan choke setting), sieve or chaffer openings that are too wide or uneven, the need for a finishing sieve, excessive tailings, or an overloaded cleaning shoe due to over threshing.
