A Kuchar Spiral Accelerator takes material off the feeder chain to eliminate back feeding and puts less stress on the chain. It feeds the rotor evenly for better threshing and separation with little to no dust coming out of the feeder house. Rocks and foreign material will be pushed into the rock trap to keep them from going into the rotor and causing damage.

​

Kuchar's Discharge Beater takes the material off the rotor faster than the OEM parts and feeds the straw chopper more evenly for a wider and better spread behind the straw chopper.
