REDUCE THE RATTLE AND CLATTER OF METAL ON METAL, GRAIN ON METAL AND CHAIN ON METAL
Grain feeds into combine over the slippery poly and helps prevent bunching in the throat. The poly does not corrode like metal and provides a smooth surface even when placed over corroded metal.
Soft plastic, rubber-like material is used to cover the metal drum where the chain hits. It saves the chain from excessive wear on the drum and decreases noise.
