reduce foreign material
In the Grain Tank
1. Check Top Sieve
An improperly set top sieve can result in short straw appearing in the grain tank. If this occurs, close the top sieve until the grain tank has 99% clean soybeans.
2. Check Bottom Sieve
If there is foreign material in the grain tank that is larger than a soybean, open the bottom sieve wide open to let air flow to the top sieve. Watch the video for full details.
3. Check Fan Speed
If there is foreign material in the grain tank that is smaller than a soybean, increase fan speed until all pod hulls have left the grain tank sample then slow down by 50 RPM.
4. Check Transport Vanes
Excessive trash in the tailings or grain tank could be from improperly set transport vanes. When harvesting soybeans with a Case IH combine, ensure the transport vanes are set to the advanced position (bottom of the transport vanes facing toward the front of the combine). This helps reduce trash intake and horsepower loss.

steps to correct problem
Increase rotor speed until the first cracked soybean appears in the grain tank, the slowdown by 10 RPM.
Start harvesting on the downwind side of the field. This helps spread straw away from the uncut soybeans in case of fire.
Foreign Material in Grain Tank
This could be caused by improper adjustments with the top or bottom sieve, fan speed or transport vanes. Watch our videos to diagnose the culprit.
For Case IH combines, adjust the transport vanes to the advanced position (bottom of the vane facing forward).
Material Congested at Head
Likely related to cross auger adjustment on auger-fed platforms, ensure clearance is set to 1/16-inch between the flighting and tray.
Synchronize reel speed to ground speed so that the reel runs at 10 times ground speed. For example, if ground speed is 4 MPH, reel speed should turning at approx. 40 RPM.
This happens more often with auger-fed platforms versus draper heads. Hear Marion's thoughts on how to reduce this problem.
Short Straw in the Grain tank
Close the top sieve until the grain tank has 99% clean soybeans.
This could be caused by a few factors, including sickle size. Click to watch Marion's three recommendations on solving this problem.
Soybean Plants Congested at Auger
If running an auger-fed bean platform, ensure the cross auger is properly adjusted. Watch the video to see Marion's full setting recommendations.
Soybean plants leaning away from header
Ensure plants are efficiently entering the header with the correct reel speed. Watch for full details.
Uncut soybean stems
Run 3-inch sickles on your bean platform to reduce the amount of uncut soybeans and plugging at the head.
uneven Spreading of Residue
Are you seeing piles of soybean chaffe in piles or tramlines in the field? If so, make sure you are harvesting on the downwind side of the field to help evenly spread residue.
Unthreshed Pods in Grain Tank
Improve the threshing power of green soybean pods by installing concave cover/filler plates in the first 12 inches.
Unthreshed Pods on Stems
It's important to have concave clearance set correctly to reduce the amount of un-threshed pods.
Unthreshed Pods in Return or Tailings
Concave cover plates help reduce this problem. Watch the video for Marion's full explanation on how to solve this common issue.
