Header compensation gauge
A gauge (8) is incorporated in the hydraulic header
lift system. When set correctly, the gauge informs the
operator whether the combine is being operated with
the header skid shoes running on or off the ground.
To set the gauge correctly, raise the header until the
skid shoes are just off the ground. Then, turn the
screw (10) until the gauge needle is centred in the
middle of the green indicator segment (9).
During field operation, the combine should then be
operated with the needle remaining in the green zone
(i.e. with the header skid shoes just of the ground).
If the needle goes into the white area, raise or lower
the header slightly.

SECTION 3 - FIELD AND SITE OPERATION
HEADER HEIGHT CONTROL
Perform the header height control calibration when
changing the header (refer to paragraph "Header
height calibrations") and the monitor calibration
(item 7).
IMPORTANT: To enter an automatic header height
control mode (compensation, Autofloatt or stubble
height), proceed as follows:
1. Engage the threshing mechanism
2. Select a mode
3. Give a pulse on the resume button (2).

24

The green autodiagnostic indicator (3) illuminates if the header is working in an automatic
header height control mode with the pre-selected stubble height (Autofloatt and stubble
height) or pre-selected pressure (compensation).
To switch from one automatic mode to
another, select the required operation mode
with the selector switch (1) and give a pulse on
the resume button (2) to enter the selected
mode.
Manually operating header height control
switch (5) always has priority of the selected
automatic height control mode (compensation, Autofloatt or stubble height) and will
also disengage this automatic mode. Re-enter
the automatic mode by giving a pulse on the
resume button (2).

25

3-25

SECTION 3 - FIELD AND SITE OPERATION
OPERATION MODES
With the header control selector switch, four different
operation modes are possible:

26
1. Transport operation = Manual
2. Compensation operation
3. Stubble height operation
4. Autofloatt or
Controlfloatt operation

Automatic
= header height
controls

IMPORTANT: Before entering an automatic header
height control mode (compensation mode, stubble
height, Autofloatt or Controlfloatt), do first the
calibrations.
Refer to headed: "HEADER HEIGHT CONTROLS
CALIBRATIONS" in this paragraph.
Transport operation
ALWAYS use this mode for road transport, attaching
and detaching the header.
This mode is automatically selected when:
o

Straw elevator is not engaged.

o

Road mode is selected.

o

Push on the header height rocker switch (5).

To use this mode, proceed as follows:
Turn the selector switch (1) in transport position and
raise the header by pressing on the upper part of the
header height control and header flotation (if
applicable) rocker switch (5).
Lower the header by pressing on the lower part of the
rocker switch (5).

on the left part of the rocker switch (5).
Tilt down the right-hand side of the header by
pressing on the right part of the rocker switch (5).

3-26

27

SECTION 3 - FIELD AND SITE OPERATION
Compensation operation
Use this mode when harvesting peas and/or laid
crops. In this operation mode, the header slides over
the ground with a pre-selected pressure.
In this mode, it is also possible to obtain an automatic lateral flotation if Autofloatt position sensors are fitted. The sensors should be connected to
the combine and the outer header skids should be in
pivoting position (i.e. hanging loose).
Turn the selector switch (1) as shown in fig. 28.
Give a pulse on the resume button (2). The header
lowers automatically at the pre-selected pressure
when the threshing mechanism is engaged.
After pressing the resume button (2), the green
autodiagnostic indicator (3) starts blinking and
remain so to show the compensation operation is
engaged.

28
While harvesting, it is possible to change the pre-selected pressure by means of the header compensation knob (6).
Turn the knob (6) counter-clockwise (+) to increase
the header pressure onto the soil.
Turn the knob (6) clockwise (-) to reduce the header
pressure onto the soil.
Operating the header height control rocker switch (5)
(vertical) disengages, the compensation system into
the transport mode [priority]. The green autodiagnostic indicator (3) will extinguish.
A pulse on the resume button (2) will bring the header
back to the compensation operation mode.
When setting compensation, it can maximum be set
at 108% of the header weight, which means that the
header will start to raise.
When setting, this height, the header will not always
follow the ground contour when passing an obstacle.
In this case, it has to be set slightly heavier.

29

3-27

SECTION 3 - FIELD AND SITE OPERATION
Autofloatt or Controlfloatt operation
[if sensors are fitted]
The header will follow the field contour at a pre-selected stubble height. Use this mode when a short
stubble is required.
The automatic compensation is built in when
touching the ground. Once the header clears the
ground, it automatically returns to the pre-set stubble
height.
Turn the selector switch (1) as shown. Give a pulse
on the resume button (2) and the header will automatically lower to the pre-selected stubble height
when the threshing mechanism is engaged.
The green autodiagnostic indicator warning light (3)
illuminates to show that the header is operating at the
pre-selected stubble height.
The pre-selected stubble height can be adjusted
while harvesting by means of the header stubble
height control knob (7).
Turn the knob (7) clockwise (+) to increase the preselected stubble height.
Turn the knob (7) counterclockwise (-) to reduce the
pre-selected stubble height.

30

Operating the header height control rocker switch (5)
vertically or sideways (lateral float) disengages the
Autofloatt or Controlfloatt system completely into
the transport mode. The green autodiagnostic indicator (3) extinguishes.
To return to the pre-selected stubble height and inclination, give a pulse on the resume button (2).

31

3-28

SECTION 3 - FIELD AND SITE OPERATION
Stubble height operation
The header operates at a pre-selected stubble
height. Use this mode when harvesting standing
crops or when operating in stony conditions and at a
higher stubble height.
In this mode the Autofloatt sensors [if installed] are
disengaged and the header can only be tilted manually by the rocker switch (5).
An automatic compensation is built in when touching the ground. After the header clears the ground, it
automatically returns to the pre-set stubble height.
Turn the selector switch (1) as shown in fig. 32.
Give a pulse on the resume button (2) and the header
will automatically lower at to the pre-selected stubble
height when the threshing mechanism is engaged.
The green autodiagnostic indicator warning light (3)
illuminates to show that the header is operating at the
pre-selected stubble height.
The pre-selected stubble height can be adjusted during harvesting by means of the header stubble height
control knob (7).
Turn the knob (7) clockwise (+) to increase the preselected stubble height.
Turn the knob (7) counter-clockwise (-) to reduce the
pre-selected stubble height.

32

Operating the header height control rocker switch (5)
vertically lowers or lifts the header into the transport
mode [priority] . The green autodiagnostic indicator
(3) extinguishes. To reenter the stubble height mode,
give a pulse on the resume button (2).

o Crop maturity and variety
o Humidity content
o Volume of straw and grain
o Weed contamination
FUNDAMENTALS OF ADJUSTMENT
o
o

o
o

o

Maximum drum speed and minimum concave
clearance, give maximum threshing efficiency.
If the grain is damaged excessively, it is
necessary to reduce the drum speed. If straw is
damaged too much it is necessary to increase
concave clearance.
if straw is damaged too much it is necessary to
increase concave clearance.
If grain is not fully separated from the ears,
increase the drum speed and/or reduce the
concave clearance.
If plugging or wrapping occurs, increase the
drum speed.

SECTION 3 - FIELD AND SITE OPERATION
o

Electrical adjustment (if applicable)

The cleaning fan speed can be adjusted electrically
with the fan speed rocker switch from the right-hand
console and can be read from the monitor.
It is only possible to change the fan speed when the
threshing mechanism is engaged.

WARNING

Do not change the fan speed if the engine and
threshing mechanism is not running to avoid
deformation of the adjustment mechanism.

Adjust it to suit the nature of the crop, chaff load and
moisture content. A low fan speed kit can be installed
to obtain a lower fan speed regulation when
threshing small seeds. An insufficient air blast will
reduce the "clean area" of the top sieve causing a
dirty sample or grain loss (grain will shake over the
end of the shaker shoe).
The best way to check whether the volume of air is
satisfactory is to complete a "kill-stall", i.e. stopping
the engine with the threshing mechanism engaged
and checking the sieve coverage pattern.
Refer to paragraph headed "Kill-stall" in this section.
If this method of checking is used:
o

The rakes must be clean while the sieves must
be evenly loaded. Little or no grain should be
found on the rear part of the upper sieve.

o

If the whole sieve is clear of grain and chaff, the
volume of air is too high. The grain will be blown
out of the machine and clean grain will be
transported over the lower sieve into the returns
cross auger.

o

If the upper sieve is full of grain, the volume of air
is too low, so that the wind does not blow through
the chaff. Therefore grain will be shaken off the
sieve together with the chaff.

Sieve operation can also be checked by collecting
material coming from the rear of the cleaning shoe
and checking the sample for grain loss.

42074

139
How to limit the returns:
1. When too much clean grain is found in the
returns elevator:
o Open the lower sieve as much as possible,
consistent with producing a clean grain
sample.
o Avoid excessive fan rpm, to prevent clean
grain from being blown over the lower sieve
into the returns cross auger.
2. When an excess of short straw and thrash is
found in the returns elevator:
o Keep the fan rpm high enough to blow the
chaff out of the machine.
o Do not open the top sieve too wide to prevent
excessive chaff from getting onto the bottom
sieve.

WARNING

Wear a dust mask when cleaning the air filter
element.
If the element is soiled with oil or soot, it is possible
to soak it for 15 minutes in a solution of 75 grammes
(0,165 lbs.) of non-sudsy detergent and
10 litres (2,6 US gal) of lukewarm water.
Rinse the element thoroughly in clean water until the
water remains clear and leave the element to dry.
NEVER WASH THE AIR FILTER ELEMENT IN
PETROL OR DIESEL OIL.
Every time the air filter element is cleaned, it should
be examined for holes and cracks by holding an
electric light bulb inside the element and looking
through it. If any damage is noted, discard the
element and fit a new one.
Replace the air filter element after 10 cleanings or
once a year, whichever comes first.
When fitting, make sure the element is seated
properly and the sealing is in good condition.

A safety element (4) is fitted as an additional security
to prevent dust from entering the engine when
replacing the standard element.
