Feeder beater must be in the UP position!! Change pulley and belt on the cylinder to 16.5 inch or 20 inch diameters. THIS IS A MUST!! Cylinder speed from 400 to 500 RPM. Raise cylinder to approx. 3/4" clearance. Change to an 1 5/8" corn chaffer. Open the lower sieve quite wide to start. Set fan control to 5 or more. Metal curtain above the raddle remove if it is still in there. Chopper needs to be slowed down or removed.

A different chaffer, not sieve. What about the cylinder pulley/belt ??? That is absolutely a requirement.

Filler bars have tendency to crack more corn. Would only use in corn you cant get off the cob. Have seen some like that over the years even at 18%.

Filler bars were only intended to be used for WET corn, say anything above 20 or 22%. It made shelling more complete and created less grain damage because the cylinder speed could be set slower and still do a good job of shelling. It also helped promote more whole cobs, which increases the separation/cleaning shoe capacity. It helped some on sidehills by keeping the crop material spread more across the full width of the cylinder. It was NOT ever intended to be left on the cylinder for doing soybeans or any other crop. Only wet or harder shelling corn.
