This right-side flail is part of the threshing mechanism in a harvesting machine. It is mounted on the rotor or beater assembly, where its pivoting head strikes the crop mat to separate grain from straw and move material across the concave. A worn or missing flail reduces threshing efficiency, leaving unthreshed heads in the straw walkers. The original manufacturer machines the flail eye to match the pin bore in the mounting bracket, preventing excessive play during high-speed rotation. When replacing, install the flail with the pivot pin oriented so the head swings freely and does not bind against adjacent components.
