SECTION 2 - CONTROLS, INSTRUMENTS AND OPERATION
Shaft speed calibration
The determination of the maximum shaft speeds is
based on a measuring period.
This period starts when:
o

after ignition key, the engine runs for the first time
at full throttle with the threshing mechanism
engaged.
or

o

each time the engine runs at full throttle with the
threshing mechanism engaged and pressing the
"ENTER" button for minimum one second on the
monitor.

NOTE: In case the operator increase the cleaning
fan speed or the drum speed during harvesting, and
a manual calibration is not done afterwards, then an
automatic calibration will be start as soon the engine
is at high idle.

2-43

SECTION 2 - CONTROLS, INSTRUMENTS AND OPERATION
Shaft speed alarm indications
A first warning buzzer alarm of 3 seconds (low level)
+ solid alarm led will be generated when the speed
drops under 85%.
A last warning buzzer alarm of 8 seconds (high level)
+ flashing alarm led will be generated when the
speeds drops under 70%.
IMPORTANT: If a warning light starts glowing during
operation and the buzzer alarm is working, the rpm
of the corresponding shaft is no longer correct (i.e.
slow-down of speed due to belt slippage, broken belt,
etc.) In this case stop the machine immediately and
investigate the cause of the problem.
Shaft speed sensor failure
If immediately after a shaft speed drop calibration
one or more leds are glowing means no speed
detection (sensor distance too big).
If there is a problem with a shaft speed sensor,
an error will be viewed on the display. A list of errors
with an explanation can be checked.
Refer to "SECTION 5 - FAULT FINDING";
paragraph headed: "ERROR MESSAGES".
Automatic shut-off
o

In case of mechanical control:
the engine will automatically shut-off when:
leaving the operator's seat after first a warning
via buzzer + led.
or
bringing the rear ladder down

o

In case of remote control:
the header will be disengaged after 7 seconds
when:
leaving the operator's seat.
or
the threshing will be disengaged when:
bringing the rear ladder down

SECTION 3 - FIELD AND SITE OPERATION
STARTING THE ENGINE
Ensure you are thoroughly familiar with the
instruments and controls before starting the engine
for the first time.
To start the engine safely, follow the points as
outlined below.

CAUTION

Before starting the engine, ensure there is enough
ventilation and everyone is standing clear of the
combine.

Daily start-up procedure
Proceed as follows:

9. Before starting the engine, warn bystanders by
sounding the horn several times.

1. Carry out the routine engine service, i.e. check
coolant, oil and fuel tank levels (refer to
"SECTION
4
-
LUBRICATION
AND
MAINTENANCE").
Ensure the battery key is in the "ON" position.

10. Turn the ignition key clockwise to engage the

3. Ensure that the unloading tube swing tumbler
switch is in neutral position.

12. Release the clutch pedal on mechanical drive
units.

4. Make sure the Multifunction handle is in neutral
position.

IMPORTANT: Allow the engine to run for minimum
one minute at low idle before moving off, to ensure
adequate lubrication of the turbocharger bearings
and the hydrostatic pump. This is especially
recommended in case of a cold start of the machine.

5. On units with mechanical drive, depress the
clutch pedal fully.
6. Check that both brake pedals are coupled
together and that the parking brake is engaged.
7. Ensure that the gearshift control lever is in the
neutral position.
8. Insert the ignition key into the ignition-and-stop
switch and turn the ignition key in the "contact"
position.
NOTE: The audible signal will sound
(indicating parking brake engaged).

3-2

IMPORTANT: If the audible alarm does not cease
functioning when the parking brake is disengaged, or
if the warning lights for the engine oil pressure or
hydrostatic charge pressure do not extinguish after
the first few seconds of idling, stop the engine
immediately and contact your dealer for assistance.

SECTION 3 - FIELD AND SITE OPERATION
STOPPING THE ENGINE
3. Remove the key from the ignition-and-stop
switch.

Proceed as follows:
1. Move the engine throttle to its minimum position
and let the engine run at idling speed for one
minute.

4. Engage the parking brake.

2. Turn the ignition key counter-clockwise to stop
the engine.

DRIVING THE COMBINE
Familiarise yourself with the different steering and
driving characteristics.

CAUTION

The combine rear end swings out when changing
direction. Take care when taking turns.

WARNING

To prevent runaway of the combine (i.e. when the
ground speed increases during downhill driving and
it is impossible to reduce the speed with the ground
speed control lever), it is necessary to shift into a
lower gear appropriate to the steepness of the hill.

Recommended gear use:
o

For field operation, use first or second gear,
depending upon the circumstances.

o

For manoeuvring in confined spaces, use
first gear.

o

For road transport, use third or fourth gear.

CAUTION

Never drive on public roads with any of the
mechanisms engaged.
NOTE: When reversing the combine, an audible
alarm will automatically warn bystanders.

MECHANICAL DRIVE UNITS

HYDROSTATIC DRIVE UNITS

Proceed as follows:
1. Fully depress the clutch pedal and move the
gearshift lever into the desired gear.
2. Release the parking brake.
3. Release slowly the clutch pedal.
4. To increase speed, push the ground speed
control lever forward.
To decrease speed, pull the ground speed
control lever backwards.
NOTE: The action of depressing the clutch pedal
automatically returns the ground speed variator to
minimum.
5. Stop the machine completely before changing
the gear.

Proceed as follows:
1. Ensure that the ground speed control lever is in
neutral position.
2. Move the gearshift lever into the desired gear.
3. Move the ground speed control lever forward
from the neutral position to advance, or from the
neutral position rearwards to reverse.
IMPORTANT: To prevent damage to the traction
gearbox it is recommended to drive the combine
slowly during the first minutes after a cold start of the
machine.

SECTION 3 - FIELD AND SITE OPERATION
COMBINE FUNCTIONS

30710

1
The combine operates according to five basic functions:
1.

Feeding

4.

Cleaning

2.

Threshing

5.

Grain storage and unloading

3.

Separation

3-4

SECTION 3 - FIELD AND SITE OPERATION
1. FEEDING
The reel 1 (on the grain header) or the gathering
chains 1 (on the maize header) feeds the crop/cobs
into the header 2 towards the auger 3. The auger 3
feeds the crop towards the middle of the header,
where it is taken by the straw elevator 4. The crop is
then carried up the straw elevator where it is fed over
the stone trap 5 into the drum 6 and concave area 7.
At this point the feeding is complete and the
threshing starts.
The stone trap 5 is designed to trap stones and other
foreign objects which may cause damage to internal
parts of the combine.

52040

2

3-5

SECTION 3 - FIELD AND SITE OPERATION
2. THRESHING

4. CLEANING

As the drum 6 rotates, it rubs the crop against the
concave bars 7. This rubbing action threshes the
grain from the straw (approximately 90% of the
grain).

The grain and the chaff are moved to the front of the
upper sieve 15 where a initial cleaning takes place.

o

Clean grain falls onto the grain pan 8.

o

Straw (and remaining grain) are guided to the
beater 9.

o

De-awning slats (accessory) can be installed on
the front part of the concave to improve the
threshing efficiency (especially important in wheat)
and to avoid white caps.

o

De-awning plates (two or four) can be installed
underneath the concave to increase the rubbing
action when threshing winter barley or difficult to
thresh crops.

3. SEPARATION
If a rotary separator is installed:
The beater 9 strips the straw from the drum 6 and
guides it into the rotary separator 10 and concave 11,
which further separates the grain from the straw.
The straw retarding curtain 12 prevents the beater 9
or the rotary separator 10 from throwing the straw too
far onto the straw walkers 13.
The straw walkers 13 oscillate, lift and tumble the
straw, permitting the remaining grain to fall through
the walkers and slide down the walkers return pans
14 onto the rear of the grain pan 8.
The straw is carried over the walkers and out of the
back of the combine and is in laid in a swath or
chopped by the straw chopper 30 (if installed).

3-6

The cleaning fan 16 blows the chaff over the upper
sieve and extension 17 out of the machine, while the
grain, unthreshed heads and small quantities of chaff
fall onto the lower sieve 18.
The lower sieve 18 finally cleans the grain. Grain that
passes through the lower sieve is carried over the
grain plate 19 to the clean grain cross auger 20.
Unthreshed heads which do not fall through the lower
sieve are transported by the returns cross auger 21
and returns elevator 22 to the drum for rethreshing.

SECTION 3 - FIELD AND SITE OPERATION
Self-levelling cleaning system (if installed)

23

The combine can be equipped with a self-levelling
cleaning system [option] which increases the
capacity of the cleaning shoe considerably when
operating in hilly conditions.
The system functions as follows:
The grain pan dividers 23 pivot to direct the grain flow
to the uphill side of the cleaning sieves, whereas the
sieve section 24 stay horizontal position, to maintain
full capacity on slopes up to 23%.

5. GRAIN STORAGE AND UNLOADING
The clean grain is channelled into the grain tank 25
by the clean grain cross auger 20, the grain elevator
26 and by the grain tank fill auger 27.
The grain tank is emptied by the grain tank unloading
auger 28 and the unloading tube auger 29.

SECTION 3 - FIELD AND SITE OPERATION

COMBINE PERFORMANCE CHECK
Kill stall
The only way to accurately check the performance of
the combine is to complete a "kill-stall".

12. With all previous factors considered, readjust the
combine.

1. Operate the combine in a section of the field that
best represents the overall crop. Be sure the
combine is at least 100 m (328 ft) into the crop
and travelling at the normal operating ground
speed.

NOTE: Make only one adjustment at a time so that
any change in combine performance can be
attributed to that particular adjustment.

2. Press on the "ESC" button for minimum four
seconds to get an engine quick "kill-stall". Apply
the brakes gently and allow the complete
combine to stop. This will leave crop material as
it was during actual harvesting.

There are four indicators, which will tell you how well
the combine is performing. These four indicators are:
o

Grain tank sample

3. Disengage the threshing
engagement system.

o

Distribution of material on the grain pan and
upper sieve

If hydrostatic drive: Move the multi function
handle to neutral.

o

Type and amount of returns
Losses

If mechanical drive: Press down on the clutch
pedal and move the gearshift lever into
neutral.

o

o

and

4. Move the throttle control to the lowest position
and restart the engine immediately. This
prevents the engine from overheating and from
being damaged. Run the engine on low idle for
five minutes before stopping the engine.
5. Check the grain tank sample for complete
threshing, cleanliness and damage.
6. Walk out in the front of the header and check the
crop loss before the header has contacted the
crop (preharvest loss).
7. Check the crop loss in an area where only the
header has travelled (header loss).
8. Check the distribution of material on the grain
pan.
9. Check the type, amount and distribution of
material on the sieves.
10. Check the type and amount of returns.

Performance indicators

By correctly reading these indicators and being
familiar with the combine, you can make the
necessary adjustments to correct any problem and
improve the overall combine performance.
Grain tank sample
A large amount of trash in the grain tank indicates the
crop is being overthreshed and/or the cleaning fan
speed is too slow. The first step to correct this
problem is to increase the concave clearance and/ or
reduce the drum speed. This reduces or eliminates
the material break-up caused by overthreshing.
Then increase the cleaning fan speed if the trash is
heavier than the grain or close the upper sieve if the
trash is larger than the grain.
Cracked or damaged grain is mainly caused by too
high drum speed. Increase the concave clearance
and then reduce the drum speed to correct the
problem.
Bunch feeding can cause grain damage in the straw
elevator. An incorrect straw elevator chain tension
can also cause grain damage.

11. Check the total loss in a 60 cm (23-5/8") wide
area across the width of the straw walkers.
Subtract preharvest and header losses to
determine the machine loss. Use a drop screen
to check the machine loss directly.
3-15

SECTION 3 - FIELD AND SITE OPERATION
Excessive returns will contribute to grain damage
due the additional pass(es) the grain must take
through the drum/concave area. Plugged concave
can cause grain damage because the free grain
cannot get out of the concave area.
Loose elevator chains can also cause grain damage.
It is important to maintain the proper tension on these
chains.
Unthreshed material in the grain tank can be caused
by underthreshing or the lower sieve that is opened
too wide. Increase the drum speed and reduce the
concave clearance as needed to correct the
problem. Reduce also the lower sieve opening
slightly to obtain a cleaner grain tank sample.
Grain pan/upper sieve distribution
The distribution of material on the grain pan affects
the distribution of material on the sieve. The
distribution on the grain pan should be level.
The front third of the upper sieve should be
completely clean. The middle third should have
some grain but mostly residue. The rear third of the
upper sieve should have only residue.
If there is some grain on the rear third of the upper
sieve, returns will be increased and there is a
possibility that grain will ride out the back of the
combine. Open the upper sieve to allow more of the
grain to fall onto the lower sieve.
If the material on the upper sieve is broken into small
pieces, the crop is being overthreshed. This can plug
the upper sieve and cause high losses. Increase the
concave clearance and/ or reduce drum speed to
decrease the threshing action.
Unthreshed heads indicate the drum speed should
be increased and/ or the concave clearance should
be reduced. Unthreshed heads can also be caused
by worn rasp bars and worn concaves.

Return sample
It is normal for the return sample to contain a few
unthreshed heads. The purpose of the returns
system is to return unthreshed heads to the
threshing area for another pass. However, a large
quantity of unthreshed heads indicates the concave
clearance is too wide.
If the return sample contains a large quantity of clean
grain, the cleaning fan speed should be reduced and/
or the lower sieve should be opened more.
Losses
Losses may occur at different stages: (see fig. 7)
1. Pre-combining losses: (i.e. losses found in
front of the combine) are usually caused by
adverse weather conditions, poor crop
conditions and crop maturity.
2. Header losses: (i.e. losses found behind the
header and outside of the tyres) may be caused
by improper header adjustments.
3. Leakage losses: may be caused by damaged
seals or holes in bottom auger covers.
4. Cleaning shoe losses: may be caused by a
poor sieve adjustment, a low or too high cleaning
fan speed, or when working on slopes
(exceeding the capacity of the self levelling
system (if fitted).
5. Straw walker losses: These can be unthreshed
ears (underthreshing) or grains, due to poor
adjustment of drum and concave or excessive
ground speed.

Total losses (Lt) caused by the machine:
Lt = (2 + 3) + (4 + 5) - 1

Functional losses (Lf)
Lf = 4 + 5

3-16

SECTION 3 - FIELD AND SITE OPERATION

7
The area of loss is determined by the location of the
grain in relation to the combine. Each of these areas
must be checked to accurately determine which
combine adjustments (if any) can be made to reduce
the loss.
Grain on the ground in front of the combine head is
defined as preharvest loss and is usually caused by
the weather. Determine the amount of this loss
before taking the combine into the field.
Grain found behind the head, but to the outside of the
drive tyres, is considered loss from the head. These
losses can be caused by improper head adjustments
or improper combine ground speed.

Shoe losses can be caused by a build-up of material
on the top sieve which allows the grain to ride out the
back of the combine. This can be due to the sieve
opening being closed or opened too much, the rear
of the sieve raised too high (sieve angle too
extreme), by a too low cleaning fan speed or a sieve
overload by too aggressive threshing in brittle crops.
Losses can also be caused by a cleaning fan speed
that is too high. The grain is then blown out of the
back of the combine.
An uneven loading of material on the top sieve can
also cause losses.

Grain on the ground directly behind the combine and
the width of the shoe is caused by incorrect combine
adjustment(s), too high a ground speed, or leakage.
Holes in the auger bottoms and damaged seals can
result in large losses which are often mistaken for
shoe and straw walker losses.

3-17

SECTION 3 - FIELD AND SITE OPERATION
How to obtain an idea on loss level
Example:
A 6-straw walker combine with a 17 ft (5.10 m)
grain header operating in wheat.
Average yield: 5000 kg/ha.

8
o

Surface P= surface being harvested:
1 meter multiplied by X (header width) = 5.10 m2.

o

Surface Q = surface of the material being cut in
surface P, behind the machine (i.e. swath):
1 meter multiplied by Y.
(drum width, i.e. 1.5 meter) = 1.5 m2.

o

Consider a loss level of 1% = 50 kg/ha or
5 grams/m2 crop.
Surface Q will then contain the functional losses
(i.e. cleaning shoe, straw walker, fan) of surface
P (5.1 m2), being 5x 5.1 = 25.5 grams.

o

Considering the average weight of wheat being
23000 grains/kg, this means: 586 grains in
surface Q. (1% loss level!)

o

An average human hand with spread fingers
covers a surface of approximately 0.03 m2. This
means that, if the grain loss is evenly spread, 18
grains can be found underneath the hand,
representing 1% grain loss for a 5000 kg/ha yield.

SECTION 3 - FIELD AND SITE OPERATION
Header and straw elevator reversing system
The combine is equipped with a system to reverse
the header auger (or the gathering chains, in case of
a maize header), the auger and the straw elevator
should a blockage occur.
If, during operation, a feed auger and/or a straw
elevator blockage occurs which makes the slip
clutch(es) slip, proceed as follows:

19
1. Stop the forward travel of the combine
immediately and disengage the header drive by
pressing on the top of the orange cap (3) or by
using the header engaging lever (6).
2. Reverse the combine a few metres.
3. Let the engine run at maximum speed.

20
4. Press on the header and straw elevator reverser
button (8) to reverse the rotation of the header
and straw elevator.
5. When the blockage has been expelled, engage
the header with the header engagement
switch (3) or by using the header engaging lever
(6).

21
IMPORTANT: It is not possible to remove all
blockages using the reversing system. If necessary,
remove the blockage manually. Refer to the next
paragraph "header and/or straw elevator
blockage-manual clearing".
NOTE: If the blockage can not be removed by the
reversing system, stop the engine before attempting
to unplug manually.
6. Continue operation.

SECTION 3 - FIELD AND SITE OPERATION
Manual clearing of the header and straw
elevator blockage

CAUTION
If the blockage cannot be removed by means of the
reversing system, disengage all engagement
systems, stop the engine, remove the ignition key
and wait until all moving parts have completely
stopped.
If the blockage is situated at the upper shaft of the
straw elevator, gain access through the cover on the
top side of the straw elevator or detach the header
with the straw elevator from the combine (refer to the
paragraph headed "Straw elevator removal", further
in this section).
If the blockage is situated at the straw elevator lower
shaft, it will be necessary to detach the header. Refer
to "SECTION 3 - FIELD AND SITE OPERATION",
paragraph headed "Detaching the header from the
combine".
Stubble height indicator (if applicable)
The crop cutting height can be read out on the
stubble height indicator 6 which is located on the
operator's platform.
If adjustment is necessary, proceed as follows:
1. Park the combine on a level ground.
2. Lower the header onto the ground.

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).
Tilt down the left-hand side of the header by pressing
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).

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

Change the fan speed only when the threshing
mechanism is engaged.

CAUTION
Be careful when changing the fan speed, as the
threshing mechanism is engaged.
The fan speed cannot be checked on the
tachometer.

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.

Returns
IMPORTANT: For maximum efficiency, keep the
amount of material in the returns elevator to the
absolute minimum.

4

Excessive returns will:
o High risk of grain damaging.
o Sieve overload with consequent grain loss.
The amount of returns can be checked through cover
4 after performing a kill stall.
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.

A cover plate is fitted over the grain tank unloading
auger. This cover plate is fitted with the plate 12,
which can be adjusted to regulate the unloading rate
according to the nature and moisture content of the
grain being handled.
To increase the unloading rate, raise the plates; to
reduce, lower the plate.

Unloading tube
The unloading tube is controlled hydraulically from
the operator's platform. A warning light is provided in
the cab to alert the operator when the unloading tube
is not in the fully closed position as this can be an
operating hazard in fields with trees, high tension
wire pylons, telegraphic poles, etc.
