HEADER HEIGHT CONTROLS -- Figures 1 and 2

When changing the header, perform the header

height control (refer to paragraph ‘‘Header height con-

trol calibrations’’ and ‘‘InfoView Monitor’’, subheading

‘‘7. Calibrations’’).

IMPORTANT:

To enter an automatic header height control

mode (compensation, autofloat or stubble

height), proceed as follows:

1. Engage the threshing mechanism

2. Select a mode, and

3. Give a pulse on the automatic header

height control mode with the preselected stub-

ble height (autofloat and stubble height) or

preselected pressure (compensation).

To switch from one automatic mode to another,

select the required operation mode with selec-

tor switch 17 and give a pulse on automatic

header height control switch 20 to enter the se-

lected mode.

Manually operating header height control

switch 13 always has priority of the selected

automatic header height control mode (com-

pensation, autofloat or stubble height) and will

also disengage this automatic mode. Re-enter

42972

the automatic mode by giving a pulse on switch

20.

SECTION 4

NOTE

Figure 3:

When using a grain or maize header fitted with

autofloat sensors, plug A must be plugged into

socket B.

When using a flex header, plug A must be

plugged into socket C, as shown.

NOTE:

S The header calibration must be performed

when changing the header.

S To operate a flex header, the autofloat op-

51714

eration mode must be selected.

OPERATION MODES

With the header control selector switch 17 four differ-

ent operation modes are possible:

Transport operation -- Figure 1

ALWAYS use this mode for road transport, attaching

and detaching the header.

When the threshing mechanism is disengaged, this

mode is automatically selected.

Turn selector switch 17 fully counterclockwise and

raise the header by pushing on the upper part of

rocker switch 13 (2-speed function).

Lower the header by pushing on the lower part of

rocker switch 13 (2-speed function).

Tilt down the left-hand side of the header by pushing

on the left part of button 13.

Tilt down the right-hand side of the header by pushing

on the right part of button 13.

4-3

FIELD OPERATION

Compensation operation -- Figures 4 and 5

Use this mode when harvesting peas and/or laid

crops. In this operation mode the header slides over

the ground with a preselected pressure.

In this mode it is also possible to obtain an automatic

lateral flotation if autofloat sensors are installed.

The sensors should be connected to the combine and

the outer header skids should be in pivoting position

(i.e. hanging loose).

Turn selector switch 17 to the P-symbol.

Give a pulse on the automatic header height control

switch 20 and the header will automatically lower to

the preselected pressure when the threshing

mechanism is engaged.

After pressing the automatic header height control

switch 20, the green autodiagnostic indicator 22 will

start blinking and remain so to show the

compensation operation is engaged.

The preselected pressure can be adjusted during har-

vesting by means of the header compensation control

knob 19.

Turn counterclockwise (+) to increase the pressure of

42972

the header onto the soil.

Turn clockwise (--) to reduce the pressure of the head-

er onto the soil.

Operating the header height control rocker switch 13

[vertically] disengages the compensation system into

the transport mode [priority]. The green autodiagnos-

tic indicator 22 will extinguish.

A pulse on the automatic header height control switch

20 will bring the header back to the compensation op-

eration.

When setting the 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 contours when passing an obstacle.

In this case, it has to be set slightly heavier.

4-4

SECTION 4

Stubble height operation -- Figures 4 and 5

The header operates at a preselected stubble height.

Use this mode when harvesting standing crops or

when operating in stony conditions and at higher

stubble height.

Inthismodethe autofloat sensors [if installed] aredis-

engaged and the header can only be tilted manually

with rocker switch 13.

An automatic compensation is built in when touch-

ing the ground. After the header clears the ground, it

automatically returns to the preset stubble height.

Turn selector switch 17 to the S-symbol.

Give a pulse on the automatic header height switch 20

and the header will automatically lower to the

preselected stubble height when the threshing

mechanism is engaged.

The green autodiagnostic indicator 22 illuminates to

show that the header is operating at the preselected

stubble height.

43073

The preselected stubble height can be adjusted dur-

ing harvesting by means of the header stubble height

control knob 18.

Turn knob

clockwise

(+) to increase the

preselected stubble height.

Turn knob 18 counterclockwise (--) to reduce the

preselected stubble height.

Operating the header height control rocker switch 13

vertically lowers or lifts the header into the transport

mode [priority]. The green autodiagnostic indicator 22

extinguishes. To reenter the stubble height mode,

give a pulse on the automatic engagement switch 20.

4-5

FIELD OPERATION

Autofloat operation [if autofloat sensors are in-

stalled] -- Figures 6 and 7

The header will follow the field contours at a

preselected stubble height. Use this mode when a

short stubble is required.

An automatic compensation is built in when touch-

ing the ground. Once the header clears the ground, it

automatically returns to the preset stubble height.

Turn selector switch 17 fully clockwise. Give a pulse

on the automatic header height control switch 20 and

the header will automatically lower to the preselected

stubble height when the threshing mechanism is en-

gaged.

The green autodiagnostic indicator 22 illuminates to

show that the header is operating at the preselected

stubble height.

The preselected stubble height can be adjusted dur-

ing harvesting by means of the header stubble height

FIELD OPERATION

HEADER HEIGHT CONTROL CALIBRATIONS

Purpose

To obtain a correct functioning of the automatic head-

er height control modes (compensation / stubble

height / autofloat, if installed), three calibrations have

to be performed:

S Calibration of the ground level

S Calibration of the maximum cylinder pressure

S Calibration of the ground level through autofloat

sensors (if the autofloat system is installed)

These calibrations have to be carried out:

S At the first start-off (i.e. at the factory)

S When changing the wheel size or the header

S When adding one header lift cylinder

S When system components were replaced

To calibrate the automatic system, the appropriate

header has to be attached and the combine has to be

placed on a level surface.

Perform the two or three calibrations in sequence, ex-

cept when operating a flex header: the calibration of

SECTION 4

HEADER AND STRAW ELEVATOR REVERSING

SYSTEM

The combine is equipped with a system to reverse the

header reel (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 ele-

vator blockage occurs which makes the slip

clutch(es) slip, proceed as follows:

Model TX62

Stop the combine immediately and disengage the

header engaging lever.

Reverse the combine a couple of metres.

Leave the throttle lever at maximum speed.

Pull the spring-loaded lock A down and press the

reversing switch 45 (Fig.15).

IMPORTANT:

Hold the switch in the activated position.

This will activate the electric motor and thus re-

verse the straw elevator and header until the

blockage has been expelled.

Release the reversing switch 45 (Fig.15).

Lift-up the reel and engage the header engaging

lever.

Move the crop slowly towards the auger with the

reel.

Continue operation.

CAUTION:

If the blockage can not be removed by the

header reversing system, stop the engine

before attempting to unplug the header

manually.

4-13

FIELD OPERATION

Models TX63-TX64^PLUS-65^PLUS-66-67-68-68^PLUS --

Figures 13 and 14

Stop the forward travel of the combine immedi-

ately and disengage the header drive with the

emergency stop switch 15.

Reverse the combine a few metres.

3. a) Let the engine run at maximum speed and

switch OFF the header engagement switch 53

(Fig.15) and the unloading auger engagement

switch 55.

3. b) It is also possible to reverse the header, straw

elevator and threshing drum.

To do this, additionally switch OFF the threshing

mechanism engagement switch, lower the

42765

drum concave and switch ON the chopper en-

gagement switch.

Push and hold the reversing switch 21 to re-

verse the rotation of header and straw elevator.

NOTE:

Pushing the lower part of the reel variator

switch 14 while holding the reversing switch

21 will rotate the header and straw elevator

forwards.

5. a)

When the blockage has been expelled, lift up

the reel and engage the header by switching

ON the header engagement switch 53 (Fig.15).

5. b)

In case reversing of the header and threshing

mechanism was needed, first switch OFF the

chopper before switching ON the threshing

mechanism, consequently the chopper (if re-

quired) and finally the header.

42759

IMPORTANT:

It is not possible to remove all blockages using

the reversing system. If necessary, remove the

blockage manually. Refer to the next para-

graph ‘‘Header and/or straw elevator blockage

-- manual clearing’’.

4-14

SECTION 4

CAUTION:

If the blockage cannot be removed by the

header reversing system, stop the engine

before attempting to unplug the header

manually.

Grain headers only

Slowly move the crop with the reel to the feed

auger.

Continue operation.

HEADER AND/OR STRAW ELEVATOR BLOCK-

AGE -- MANUAL CLEARING

CAUTION:

If the blockage cannot be removed by

means of the reversing system, disen-

gage all engagement systems, shut down

the engine and wait until all parts have

come to a standstill.

If the blockage is situated at the straw elevator upper

shaft, gain access through the straw elevator bottom

plate. Refer to the paragraph below.

If theblockageissituatedat thestraw elevatorbottom

shaft, it will be necessary to detach the header. Refer

to Section 2, paragraph headed‘‘Detaching thehead-

er from the combine’’.

REEL TO GROUND SPEED SYNCHRONIZATION

With switch 43 (Fig.15) in the ON position, the reel

speed is synchronized to the ground speed. The ba-

sic ratio between the reel and the ground speed is

memorized in the central processing unit (part of the

fuse box). However, this ratio can be increased or de-

creased with the reel speed control switch

(Fig.13). The new ratio result will automatically be

memorized, replacing the existing ratio (still with

switch 43 in the ON position).

4-15

SECTION 4

NOTE:

S While activating the reel synchro by switch-

ing on the reel synchro switch 43, disregard

the fact that the reel speed increases to its

maximum speed or decreases to its mini-

mum speed.

This happens to a previous reel synchro

setting.

Adjust the reel speed with the reel variator

switch 14.

S As the electronic reel speed range is larger

than the mechanical reel speed, it may

take some seconds before the reel speed

reacts to the reel variator switch (with the

reel synchro ON).

3. Releasing the reel variator switch 14 will automati-

cally introduce the new relationship between the

reel speed and the combine ground speed in the

electronic system.

4. If you now change the combine ground speed, the

reel speed will be related automatically.

NOTE:

S If you now notice that the reel speed in-

creases or decreases too fast in relation to

the ground speed, change the ‘‘reel speed

synchro gain’’ factor (refer to paragraph

headed ‘‘InfoView Monitor’’, subheading ‘‘7.

Calibrations’’, further in this Section).

After changing the gain factor, repeat steps

1, 2 and 3.

S On headlands or whenever lifting the head-

er out of the operational zone (disengaging

of hectare counter), the reel speed will be

maintained until the header is lowered

again.
