11.3.1 When combining, remember:
– Wait until the crop has fully ripened – do not com-
bine beforehand! (Higher yield, less moisture
content and easier threshing are the result.)
– Where the heads are bent, install grain lifters
close together. Where the crop is lodged, install
grain lifters further apart (on every fourth to sixth
cutterbar finger).
– Where straw and grain are brittle, set the concave
wider and reduce the threshing drum speed. Too
much short straw impedes the cleaning process.
Cracked grain lowers the quality.
– Where the straw is long, damp and tough, reduce
the concave clearance and increase the threshing
drum speed.
– Under damp conditions and where crops are also
grown through with greenstuff, clean the concave,
straw walkers and sieves regularly.
– Remember that the vital part of the cleaning proc-
ess is the blast of the fan. Prevent the forming of
»mats« on the sieves and unnecessary grain
losses by using enough wind, adjusting the frog-
mouth sieve correctly and using a flat sieve of
sufficient hole size.
– When combining crops in which it is hard to
remove the awns, additional rasp bars can be fit-
ted to the concave.
– To get the best results from your combine run it at
the right speed. Therefore, check the speed on
the straw walker shaft before the harvest. The cor-
rect speed is 220-5 rpm.
– Correct cleaning of the air filter as well as clean
fuel and regular oil changes are essential for high
performance and long life of the engine.
