Straight separator bars may be needed for harvesting corn yielding more than 150 bushels per acre (9400 kg/ha) and in other crops during dry conditions. Increase fan speed
to 1250 RPM in wet corn.
Once installed, straight separator bars need to be removed only for harvesting rice, edible beans, and similar viney crops.
Tough rice requires the use of spiked rasp bars over the concave area and the grate area. Set concave indicators at Number 4 when spiked rasp bars are used in the concave area.
LW - Large Wire (1/4" Diameter); SW - Small Wire (3/16" Diameter); SL - Smooth Slotted.
Use of non-spiked rasp bars in all positions is recommended for most grass seed harvest conditions. Spiked bars may be helpful in extremely damp crops. Rotate fan cutoff
rearward to the vertical position to reduce air volume.
Some soybeans may require rotor speeds up to 700 RPM or more.
The front several inches of the chaffer sieve are, by design, set slightly more closed than the rest of the front section.
Slotted concave use may be beneficial to reduce damage to threshed material.
A common mis-adjustment is setting rotor speed too low. High moisture crops will require higher rotor speeds. The AFX Rotor may require an additional 50 to 100 RPM Rotor
Speed and a slightly tighter concave in some.
