There is no patent remedy when it comes to preventing grain losses. The threshing process is so complex that a certain relationship between "adjustment" and "result" must be found.
The combine operator must try to obtain the best results by referring to the summary provided below and the "Combine Settings" chart.
IMPORTANT:
Grain losses rise with the amount of material passing along the straw walkers and therefore can be easily remedied by decreasing combine ground speed.
However, do not underestimate the effect of other combine adjustments.
Reduce straw walker losses as follows:
Keep openings in straw walkers clean
Reduce weeds and green material (raise cutting platform)
|
Material overthreshed (reduce cylinder speed)
Straw walkers overloaded (reduce ground speed)
Reduce sieve losses as follows:
Increase air blast from cleaning fan if layer of straws forms on sieves
Reduce air blast (fan speed) if grain is blown over cleaning shoe
Open lips of sieve
Keep sieve clean
Add or remove insert fingers when working on slope
Reduce amount of chaff on sieves, avoid overthreshing
Sieve overloaded, reduce amount of grain over sieves (reduce ground speed)
