Sieves
Both the top and bottom sieves are adjustable
from 0 – 20mm in the cab through CEBIS. The
sieves need to be open enough to cope with
high volumes of grain, over 16mm is not
uncommon. With wide sieve settings there is a
need for high wind speed. It is recommended
that the sieves are only adjusted by 1mm at a
time.
Returns
The returns should be monitored regularly both in terms of volume and
composition. The window on RHS of the cab below the ignition switch allows the
returns to be viewed from the drivers seat. The centre tube of the auger should
always be visible. The volume of clean grains in the returns is monitored and
displayed on the bar display next to the returns monitor (optional on LEXION
740)
If too much clean grain is present, open the bottom sieve by 1mm at a time.
If too much chaff is present reduce threshing.
If un-threshed heads are present increase threshing.
In crops such as oilseed rape, where excessive trash is a problem, it may be
beneficial to close the back section of the top sieve to reduce re-circulation
through the returns.
