11.10.1 Inspecting the returns
Coarse particles (e.g. unthreshed heads) drop through
the upper sieve and from the lower sieve into the
returns auger which moves the material to the returns
elevator. The elevator carries the returns to the thresh-
ing drum for second threshing.
Excessive returns cut down on efficiency and
cause cracked grain and grain losses.
Excessive returns can have a number of reasons:
• Incorrect setting of the threshing mechanism, con-
cave, threshing drum speed (excessive cracked
grain).
• Sieves set too close or lower sieve holes
too small.
• Incorrect setting of the wind blast (too high
or too low).
• Ground speed too high.
– Engage the threshing mechanism.
– Set the diesel engine speed to fast idling
speed.
– Move the machine into the crop.
– Actuate lever (3) and open cover (2).
– Inspect the quantity and composition of the
returns (1) by means of a visual inspection.
If necessary, correct the machine setting.
