Start with the Recommended Settings
In the table at the end of this chapter you will ¿ nd settings
and adjustments for different crops. After adjusting your
combine according to these recommended settings, test
run the combine at the speed you will use in harvesting.
Monitor the quality of the grain in the tank and the losses
in the
¿ eld.

without the chopper, it is important to make sure that
all the straw comes out of the straw walkers without
clogging the chaff hood.
Reel Position in Accordance With Crop
For normal standing crops, set the reel in its rear posi-
tion at such a height that the reel tines lightly strike the
crop. Reel speed slightly higher than the combine ground
speed to ensure the crop is feeding head
¿ rst, ¿ g. M1.
For short-strawed crops, lower the reel so that the tines
strike just above the knife. The reel speed increases the
faster you drive and the shorter the straw is cut with the
heads. The reel must pull in the heads toward the table
auger.
For long-strawed standing crops, set the reel in its for-
ward position, the speed lower than the combine ground
speed so that the heads are pushed forward and the crop
is laid butt
¿ rst onto the table, ¿ g. M2.
Threshing Instructions
Choose the Correct Time and Conditions
Before starting the harvest, make sure that the crop to be threshed is ripe and dry enough. The germinating power
of most crops is easily reduced if the threshing moisture exceeds 25%.
Moreover, moist crops complicate harvesting and overload the threshing mechanism. They also easily stick onto
the surfaces of the separating equipment and elevators, which will increase the need for cleaning.
Particularly in dry conditions with moisture below 12%, straw becomes chopped extremely easily. This will hinder
the straw walker operation and burden the shaker shoe excessively.
Good Threshing Results with Even Feed
Always run the engine at maximum revolutions when threshing. When threshing, it is important to adjust the for-
ward speed, the cutting height and the reel according to crop conditions to achieve as even feed as possible. Do
not cut too low. Leafy matter moistens the straw leading to a poor threshing result.
Empty the stone trap daily. Before emptying, stop the engine, lock the parking brake and
¿ t the cutting table sup-
port.
