10.4.1 Adjusting the separation performance
monitor sensors
The cleaning and separation performance monitor
allows the operator to make full use of the capacity of
the machine.
A gauge allows the operator to determine how fast the
machine can be driven without the reasonable grain
loss limit being exceeded.
2
Grains lost over the back of the combine with the straw
2
fall onto the sensors (2). The pulses generated are vis-
ualised by meter lights on a display.
The sensors (2) react with different sensitivities to dif-
4
ferent grain sizes and must therefore be calibrated to
12
the respective grain size, using switch (4).
19647
The gauge sensitivity setting is carried out during field-
work. See Adjusting the separation performance
monitor display.
- Adjust the sensitivity of the sensors to the different
grain sizes on switch (4).

DOMINATOR 150
The grain tank full indicator indicates the 70% grain
tank filling level by means of indicator light (3) and the
100% grain tank filling level by indicator light (4) on the
vehicle information unit.
The grain tank fill indicator (1 and 2) levels can be
staggered, so that depending on the tank unloading
possibility the time span between the illumination of
the window and the tank unloading can be individually
utilised.
Big windows also allow the grain tank level to be
checked from the operator's platform.

11.1.1 General warnings Fieldwork
In the following sections of this chapter, a procedure
instruction refers to the following general warnings.
Danger!
Always stop the engine before carrying out
any work on the machine.
Moving machine parts and / or unexpected
machine movement.
Death or serious injury.
- Diesel engine OFF.
- Apply parking brake.
- Remove the ignition key.
- Remove key of battery isolating
switch.
- Wait for machine parts which run on have
come to a complete halt.
- Secure machine by wheel chocks.
- Ensure that the machine cannot be
started by any third persons.
Danger!
The front attachment, reel and feeder unit may
drop uncontrolled.
Death or serious injuries!
- Apply safety locks.
- Keep a safe distance from the hazard
area.

11.2.1 Cutterbar
Dividers separate the standing grain from the grain
which is to be cut.
Grain lifters lift lodged crops and avoid cutting losses in
crops with hanging heads.
The reel moves the cut crop to the intake auger. The
auger flights move the material to the cutterbar centre
where the feed rake delivers it to the drum for thresh-
ing. The stone trap collects solid objects brought up by
the feed rake, thus preventing damage to the threshing
parts.

11.2 Description and function

11.2.2 Threshing mechanism
Threshing is performed by drum and concave. The
bulk of the grain together with the chaff and broken
straw passes through the concave onto the prepara-
tion floor of the sieve pan. The impeller delivers the
straw and remainder of the grain to the straw walkers.
A deflector curtain behind the impeller holds back
bouncing grains and deflects them down onto the front
of the straw walkers.
69375
11.2.3 Straw walker
The straw walkers separate the remainder of the grain
from the straw. The straw is either removed out of the
combine through the rear panel or undergoes further
processing by special attachments (e. g. straw chop-
per). The grains separated by the straw walkers are
returned to the sieve pan via the under-walker return
floor. Crankshafts with agitator tines intensify the loos-
ening of the straw on the straw walkers.
69377
11.2.4 Cleaning unit
Grain mixed with chaff and broken straw is fluffed by
means of the shaking action of the preparation floor
and at the same time moved onto the sieves.
The wind blast of the cleaning fan blows the light parti-
cles (chaff) to the rear, out of the machine. The grain
falls through the upper and lower sieve into the clean
grain auger trough and is conveyed into the grain tank
by the clean grain elevator. All parts heavier than chaff
and bigger than grain travel over the upper sieve and
lower sieve, drop into the returns auger and are moved
to the returns elevator. The elevator carries the returns
to the drum for further threshing. Swinging the grain
tank unloading tube into operating position allows the
grain tank to be quickly emptied into a truck or trailer
alongside the combine.
69380
11.2.5 Disawning
When combining grain which is unusually hard to dis-
awn or in which it is hard to separate the seeds from
the heads or husks, additional disawning plates can be
installed in the concave.
