This lower sieve finger is a flexible element mounted on the lower sieve of the threshing mechanism. It agitates the sieve surface to keep crop material moving and prevent blockages during separation. A set of ten fingers is included. Worn or broken fingers reduce sieve cleaning efficiency, leading to increased grain loss over the walkers. The original part matches the mounting hole pattern and material stiffness of the factory assembly, so the sieve's oscillation frequency and amplitude remain as designed.
