Grain quality

Sieves plugging with straw and chaff

Possible Cause

Correction

Insufficient air blast from cleaning fan.

Increase fan choke setting.

Sieve opening too wide.

Consider increasing air, then decrease 
sieve opening in 0.06” (1.6 mm) 
increments.

Chaffer opening too wide.

Decrease chaffer opening in 0.06” (1.6 
mm) increments.

Missing or improperly installed fan inlet 
screen.

Properly install all fan inlet screens.

Shutting down machine before it has 
cleaned out.

Allow crop to pass through and clear 
machine before disengaging separator.

Incorrect chaffer for crop being 
harvested.

Round end, shallow tooth 1.125” (28.6 
mm) spacing - used in all crops except 
corn. Round end, deep tooth 1.625” 
(41.3 mm) spacing - generally used 
in corn but has also been found to 
provide desired cleaning in some crops 
such as soybeans and high moisture 
cereal grains where more air volume is 
desired.

Square end, deep tooth 1.625” (41.3 
mm) spacing - generally used in high 
moisture corn to remove pieces of cob 
from the grain tank sample.

Incorrect air pattern.

Inspect fan, fan choke, shoe air duct 
and splitter location.
