Wet Harvest Recommendations
In wet and laid crops
It is even more important to get a good cut and feed into the combine. Check
the knife and fingers regularly, paying particular attention to the knife to finger
gap.
To pick up laid crops
The skids under the bar must be raised into their highest position. This will
also reduce the amount of soil sticking to the underside of the cutterbar.
Do not try to go too low with the cutterbar in laid crops
You only need to place the point of the lifter on the ground. If you go too low,
the point of the lifter will lift and hold the crop down.
Soil and foreign objects
These are more likely to enter the combine in a wet harvest, it is vital that
the stone trap be emptied at least daily. The worse the conditions, the more
frequently this should be done.
Emptying the stone trap
Check that the APS concaves are clean. To do this, simply open the
concave to 50mm before switching off and emptying the stone trap.
Under the concave is the preparation pan
This will become dirty as wet grain and soil passes over it. The dirtier it
becomes, the less effective it will be, and hence, the dirtier the sample will
become. With wet grain it is important to try to keep to a cleaner sample than
normal, as you then waste less fuel drying chaff etc.
If the preparation pan is dirty
This is your first indication that further cleaning inside the combine may well
be required. When cleaning the rest of the combine, follow the path of grain
through the machine, and open covers as you come to them.
