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.
IMPORTANT:
Grain loss increases 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 grain losses as follows:
-
Keep openings in straw walkers clean.
-
Reduce weeds and green material (raise platform).
-
Avoid material overload (reduce cylinder speed).
|
-
Avoid overload of straw walkers (reduce ground speed).
Reduce sieve losses as follows:
-
Increase air blast from cleaning fan if layers of straw form on cleaning shoes.
-
Reduce air blast (fan speed) if grain is blown over the top of cleaning shoe.
-
Increase cleaning shoe spacing.
-
Keep cleaning shoes clean.
-
Add or remove insert fingers to "Slope Master" when working on slopes.
-
Reduce amount of chaff on cleaning shoes, avoid overthreshing.
-
Avoid overloading cleaning shoes, reduce amount of grain over cleaning shoes (reduce ground speed).
