Adjusting the threshing drum speed

H

DOMINATOR 130

- Unblock the threshing drum gate (7 / 8) with

lock (Y).

Reducing the threshing drum speed

- Move lever (1) from the neutral position (N)

7

towards (7), thus reducing the threshing drum

speed.

8

Increasing the threshing drum speed

Y

- Move lever (1) from the neutral position (N)

speed.

Blocking the threshing drum gate

- Block threshing drum gate (7 / 8) with lock (Y).

Consequently, the drum speed cannot be acciden-

tally changed.

11.6.7 Threshing drum two-step variable-

speed drive (chain drive)

- Observe the general warnings at the beginning of

the "Fieldwork" chapter.

An optional chain drive kit for threshing crops that

crack easily can be installed in place of the drum varia-

ble-speed drive.

Three speeds can be obtained by changing sprockets

4

(2). An additional fourth speed can be obtained by

replacing sprocket (1) on the impeller shaft.

11.7.1 Adjusting the deflector curtain

- Observe the general warnings at the beginning of

the "Fieldwork" chapter.

The deflector curtain (1) can be height-adjusted on the

right side of the machine, using a chain.

In the basic grain setting, the deflector curtain is hang-

ing down freely.

Raise the curtain in heavy, long-strawed crops and

where a lot of greenstuff is encountered.

1

It is essential to lower the curtain again in short-

strawed light crops.

36

19623

- Unlock chain (2) at position (A) and adjust its

length.

The deflector curtain can be set higher or lower.

The deflector curtain can yield to the rear.

11.7.2 Observe the straw blockage warning

downstream of the separation stage

In case of a straw jam downstream of the separation

stage, cover (1) is actuated and the horn on the opera-

tor's platform produces a horn tone.

WARNING:

Straw plug.

Machine damage.

- Immediately stop the machine and

remove straw plug.

11.7.3 Adjusting the separation performance

monitor display

The cleaning and separation performance monitor

allows the operator to make full use of the capacity of

the machine.

The display (3) 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 excited pulses are visual-

ised by the meter lights of the display (3).

The sensitivity of the separation display can be set

depending on the properties of the crop (straw mois-

39

ture, green part, grain shape, leaf content of straw).

19647

- Adjust the separation performance monitor

sensors.

3

- Set the sensitivity of the separation display and

the desired individual grain loss limit at switch (4).

The display reacts more sensitive / less sensitive,

depending on the adjusted set value.

Check the grain loss limit. Proceed as follows:

- Prepare fieldwork.

4

- Set the machine depending on the crop. See

threshing chart.

40

- Engage front attachment.

DOMINATOR 150 / 140

19558

- Engage the threshing mechanism.

- Drive the machine into the crop at the speed

appropriate for the crop.

- Stop the machine when the forth to fifth light of the

meter light (3) lights up constantly after a sufficient

distance has been covered.

- Check the losses in the swath.

4

- If loss is at an acceptable level, continue operation

with selected setting.

3

- When losses on the straw walker are too high,

increase the gauge sensitivity by about half to one

step, using switch (4).

41

DOMINATOR 130

19412

Now adjust forward speed until the fourth or fifth

light in the meter light (3) lights up again.

- When excessive losses on the straw walker con-

tinue, check the machine setting regarding

concave clearance, drum speed and deflector cur-

tain setting.

If the loss rate, indicated by the fourth or fifth light in

the meters, is acceptable, the capacity of the combine

is fully utilised at this forward speed.

11.8.1 Adjusting the fan speed

The cleaning fan blows all light particles out of the

machine from below. Excessive “matting” of grain,

chaff and broken straw on the upper sieve can be pre-

vented by having sufficient volume of wind. The wind

blast also helps to fluff up the material.

The speed can be infinitely varied with crank (1). The

crank is decelerated by a spring and is therefore pro-

tected against unintended misadjustments.

- Engage the threshing mechanism.

- Set the diesel engine speed to fast idling

speed.

-

Note!

Constructive conditions.

Machine damage.

- Adjust the fan speed only when the

threshing mechanism is engaged.

- Adjust fan speed with crank (1) until the desired

44

speed is shown on gauge (2).

Fan speed

Gauge value x 100 = approx. fan speed in rpm.

The speed must be set depending on the crop. See

threshing chart.

Basic rule: Set the fan speed as high as possible,

depending on crop conditions.

The frogmouth sieves are adjustable for all grain sizes

by levers.

Lever (5) is used to adjust the upper frogmouth sieve

over its full length, including the returns passthrough

area (4).

Lever (6) is used to adjust only the returns pass-

through area (4).

- Adjust the grain sieving (3) of the upper frogmouth

sieve with lever (5) so that the grain quantity is

sieved after three fourths of the sieve area has

been sieved.

47

19639

- Always set the returns sieving (4) of the upper

frogmouth sieve with lever (5) for all crop types

wider than the grain sieving (3), so as to prevent

ears not threshed out from falling through and get-

ting into the returns. Check returns.

3

- Adjust the lower frogmouth sieve with the lever (7)

so that the crop in the grain tank corresponds to

4

the desired quality. Check returns.

The cleaning and separation performance monitor

allows the operator to make full use of the capacity of

the machine.

The display (3) allows the operator to determine how

fast the machine can be driven without the reasonable

grain loss limit being exceeded.

2

The grains carried out through the sieve fall on the

sensor (2). The excited pulses are visualised by the

meter lights of the display (3).

The sensitivity of the cleaning system display can be

adjusted depending on the properties of the crop

49

(grain moisture, grain shape, green part).

depending on the adjusted set value.

Check the grain loss limit. Proceed as follows:

- Prepare fieldwork.

- Set the machine depending on the crop. See

threshing chart.

- Engage front attachment.

50

- Engage the threshing mechanism.

DOMINATOR 150 / 140

19558

- Drive the machine into the crop at the speed

appropriate for the crop.

- Stop the machine when the forth to fifth light of the

meter light (5) lights up constantly after a sufficient

distance has been covered.

- Check the losses in the swath.

- If loss is at an acceptable level, continue operation

6

with selected setting.

- When losses on the sieve are too high, increase

the gauge sensitivity by about half to one step,

5

using switch (6).

51

Now adjust forward speed until the fourth or fifth

DOMINATOR 130

19412

light in the meter light (5) lights up again.

- When excessive losses on the sieve continue,

check the machine setting regarding concave

clearance, drum speed, fan speed and sieve

setting.

When the cleaning is properly adjusted, one of the

lights at the bottom of the meter light (5) lights up.

The cleaning and separation performance monitor

should be adjusted as described to suit changing

losses in the morning, when the crop is wet with dew,

at noon when the crop is absolutely dry, and in the

evening when the crop gradually gets damp.
