11.3 Considerations before combining
67087
11.3 Considerations before combining
69384
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.

Threshing drum variable-speed drive
The threshing drum speed can be infinitely varied from
2
650 to 1500 rpm by the threshing drum variable-speed
drive.
The speed variation combined with concave adjust-
1
ment allows quick adaptation of threshing operations
in order to match different crop conditions. Damp long-
strawed crops as well as crops difficult to thresh and
3
disawn require faster drum speeds than dry and brittle
crops.
The speed must be set depending on the crop. See
29
threshing chart.

- Engage the threshing mechanism.
- Set the diesel engine speed to fast idling
speed.
