Combines Feeder House Chains 1660

I'm talking about the very front feeder drum, the one the feeder chain goes around in the front of the feederhouse. It floats up and down on two arms. A stone retarder drum has groves where the actual chain runs, there is no gap between the slats and the drum. A smooth, or non-stone retarder drum, is smooth, thus making the slats stand away from the drum.

We have the smooth drum where the chain stands out from the drum itself.
