New Holland CX720, CX740, CX760, CX780, CX820, CX840, CX860, CX880. Operator's Manual

SECTION 2 - CONTROLS, INSTRUMENTS AND OPERATION

AUDIBLE ALARM

An audible signal (buzzer) is linked with all the

different levels of alarms (low, medium, high).

A pop-up screen on the Infoviewt shows the

explanation of the specific alarm.

NOTE: When the alarm is functioning, try to locate

the defect or contact your local dealer for assistance.

AUTOMATIC ENGINE SHUT-OFF

In case of an emergency, in order to prevent engine

or hydrostatic system damage, or to protect your

personal safety, the engine will automatically be shut

off immediately, if the following elements occur:

• Low engine oil pressure

(+buzzer alarm + InfoViewt)

• Excessive engine oil and engine coolant

temperature (+buzzer alarm + InfoViewt)

• Low hydrostatic oil pressure

(+buzzer alarm + InfoViewt)

• Engine gearbox oil pressure

(+buzzer alarm + InfoViewt)

NOTE: If it is necessary to move the combine for

safety reasons, the engine can be (re-)started after

an “automatic engine shut-off” (the engine will only be

shut down after 30 seconds in this case). In this case,

the operator assumes the responsibility for any

engine damage or failure.

SECTION 3 - FIELD AND SITE OPERATION

PARKING BRAKE

The parking brake is operated by pressing tumbler

switch 1.

The parking brake has two positions.

• The first position: Off position

NOTE: When selecting another gear, the parking

brake is activated automatically during shifting.

• The second position: Parking position

NOTE: Each time the engine is started, the parking

brake will be activated. (even if the parking brake

tumbler switch is set in the “OFF” position) To release

the parking brake, set the parking brake tumbler

switch first in the “ON” position after in the “OFF”

position.

NOTE: When the “ON” (parking) position is selected

during driving, the parking brake will be activated

when the multifunction handle (hydrostatic) is moved

to neutral position or the ground speed is lower than

0.5 km/h (0.3 mph).

Emergency stop (If configured in InfoViewt

)

Pressing quick stop button 2 on the multifunction

handle while driving the combine will cause the

combine to stop.

Depending on the time button 2 is pressed, the

combine will stop like explained below:

• If pressing not longer than two seconds on

quick stop button 2:

The hydrostatic will be disabled immediately.

• If pressing between two and six seconds on

quick stop button 2:

The hydrostatic will be disabled immediately.

After two seconds the parking brake will

come on additional, during four seconds.

• If pressing for a minimum of six seconds on

quick stop button 2:

The same result will occur when pressing

between two and six seconds, but after six

seconds the parking brake will close

completely to stop the combine abruptly.

Remark: After an emergency stop, to advance again,

bring first the multifunction handle back to the neutral

position (the parking will be released automatically).

3-4

SECTION 3 - FIELD AND SITE OPERATION

Gear shifting system

A selector switch

(1-2-N-3-4) indicates the

selected gear.

Selecting a gear is only possible with the

multifunction handle in neutral position.

Turn the button to select a gear. The parking brake is

automatically engaged and the hydrostatic system

will be disabled.

The InfoViewt shows the selected gear on top of the

screen when the gearshifting is completed. The

parking brake will reset to its previous state and the

operator can take over the hydrostatic control.

Remark: When selecting another gear during driving,

the system will wait until the multifunction handle is in

the neutral position and the combine is stopped

completely.

Differential lock (if equipped)

When operating in slippery or muddy ground

conditions the differential lock may be engaged to

provide better traction.

If one of the traction wheels start spinning,

immediately depress the differential lock pedal (1).

Now both traction wheels will turn at the same speed.

Keep the pedal (1) depressed until the machine has

passed the obstacle.

Release the pedal to disengage the differential lock.

IMPORTANT:

• Do not make turns with differential lock pedal

depressed.

• It may be necessary to slow down the combine to

allow engagement of the differential lock.

How to obtain an idea on loss level

CAUTION

The straw chopper must be disconnected when

checking loss.

Example:

A 6-straw walker combine with a 17 ft (5.10 m)

grain header operating in wheat.

Average yield: 5000 kg/ha.

• Surface P= surface being harvested:

1 meter multiplied by X (header width) = 5.10 m².

• 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.

• 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 5 x 5.1 = 25.5 grams.

• Considering the average weight of wheat being

23000 grains/kg, this means:

586 grains in

surface Q. (1% loss level!)

• 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 HEIGHT CONTROLS

When changing the header (grain header), perform

the header settings and header calibrations (refer

to “SECTION 2 - CONTROLS, INSTRUMENTS AND

OPERATION”, Paragraph: ”VI CALIBRATIONS AND

CONFIGURATIONS”.

To enter an automatic header height control mode

(stubble height and/or Autofloatt, compensation),

proceed as follows after doing first the calibrations:

Stubble height and Autofloatt mode

In this mode, without Autofloatt potentiometer

sensors, the header operates at a preselected

stubble height.

If the Autofloatt potentiometer sensors are installed,

the header will follow the field contours at a

preselected stubble height.

1. Engage the threshing mechanism and the straw

elevator with switches 1 and 2.

2. Set header memory tumbler switch 4 in stubble

height/Autofloatt mode position 1 or 2.

3. Lower the header to the desired cutting height

using header height and header lateral flotation

rocker switch 3.

4. Press automatic header height control button 6

for minimum 2 seconds to store.

(A beep will confirm)

NOTE: It is possible to store two different header

heights values by using header memory tumbler

switch 4 in stubble height/Autofloatt mode position

1 or 2.

5. To change one of the memorised header height

setpoints during working, using the header height

and header lateral flotation rocker switch 3 (slow

up/down) to raise or lower the header to the

desired value. Press the automatic header height

control button 6 for minimum 2 seconds to store

the new height position. (A beep will confirm)

6. At the headlands the operator can press

automatic header height control button 6 twice to

lift the header out of the crop.

To reenter the automatic mode give a pulse on the

automatic header height control button 6 and the

header will be relower to the preselected height

position.

3-23

SECTION 3 - FIELD AND SITE OPERATION

NOTE: To change only the working setpoint, press

slow up/down with header height and header lateral

flotation rocker switch

3 without confirming by

automatic header height control button 6. The system

will stay in automatic mode.

NOTE: Operating the header height control rocker

switch 3 (only fast speed up or down, no lateral tilt)

disengages the automatic mode system completely

into the transport mode (priority).

NOTE: It is also possible to switch over from one

header height to an other or even to header

compensation by using memory tumbler switch 4.

IMPORTANT: It is only possible to change the header

height position as long as they are working in the

range of the “Maximum stubble height”. To change

the maximum stubble height, refer to “SECTION 2 -

CONTROLS, INSTRUMENTS AND OPERATION”,

paragraph

“VI:

CALIBRATIONS

AND

CONFIGURATIONS”, headed “11.Header”.

An automatic compensation is build in when

touching the ground. After the header clears the

ground, it automatically returns to the preset

stubble height. This automatic compensation can

be adjusted with the threshold pressure. A lower

threshold pressure will limit forces on the ground

when touching the ground.

Refer to

“SECTION

CONTROLS,

INSTRUMENTS AND OPERATION”, paragraph

“VI: CALIBRATIONS AND CONFIGURATIONS”,

headed “11.Header”.

3-24

SECTION 3 - FIELD AND SITE OPERATION

Compensation mode

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 Autofloatt potentiometer 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).

1. Engage the threshing mechanism and the straw

elevator with switches 1 and 2.

2. Set header memory tumbler switch

4 in

compensation mode.

3. Lower the header to the desired cutting height

using header height and header lateral flotation

rocker switch 3.

4. Press automatic header height control button 6

for minimum 2 seconds to store.

(A beep will confirm)

NOTE: The calibrated header pressure means the

pressure in the header lift cylinders with the header

+/- 15 cm (6 inches) above the ground.

5. To change the preselect pressure during working,

using the header height and header lateral

flotation rocker switch 3 (slow up/down) to the

desired pressure. Press the automatic header

height control button 6 for minimum 2 seconds to

store the new pressure. (A beep will confirm)

6. At the headlands the operator can press

automatic header height control button 6 twice to

lift the header out of the crop.

To reenter the automatic mode give a pulse on the

automatic header height control button 6 and the

header will lower until the preselected pressure is

obtained.

NOTE: To change the pressure, press slow up/down

with header height and header lateral flotation rocker

switch 3 without confirming by automatic header

height control button

6. The system will stay in

automatic mode.

NOTE: It is also possible to switch over from one

header height to an other or even to header

compensation.

3-25

SECTION 3 - FIELD AND SITE OPERATION

Transport mode

This mode is automatically selected when:

• Straw elevator is not engaged.

• Road mode is selected.

• Push on the header height rocker switch.

Flex header operation

To work with a flex header perform the header type

configuration. Refer to “SECTION 2 - CONTROLS,

INSTRUMENTS AND OPERATION”, paragraph:

“VI CONFIGURATIONS AND CALIBRATIONS”,

headed: “11.Header”.

AUTO HEADER LIFT

This automatic system is build in to protect the header

skid shoes by reversing the combine.

• Flex header: The header lift up two seconds after

the header skid shoes no more touching the

ground.

• Other headers: The header lift up one second

after the header skid shoes no more touching the

ground.

To get this system, the following conditions has to be

done.

• Auto header lift installed, refer to

“SECTION 2 - CONTROLS, INSTRUMENTS

AND OPERATION”, paragraph:

“VI CONFIGURATIONS AND CALIBRATIONS”,

headed: “11.header”.

• Autofloatt installed, refer to

“SECTION 2 - CONTROLS, INSTRUMENTS

AND OPERATION”,

“VI CONFIGURATIONS AND CALIBRATIONS”,

headed: “11.header”.

3-27

SECTION 3 - FIELD AND SITE OPERATION

REEL TO GROUND SPEED SYNCHRONIZATION

The reel to ground speed synchronization system is

an automatic system which, if switched on with the

reel speed synchronization engagement switch 3,

creates a linear relation ship of the reel speed with the

ground speed.

The basic ratio between the reel and the ground

speed can be increased or decreased with the reel

speed control switches 1 and 2.

• A= Reel speed (km/h)

• B= Ground speed (km/h)

• C= Minimum reel speed

(setting with InfoViewt monitor)

• D= Auto reel speed slope

(depends the header type)

• E= Auto reel speed offset

IMPORTANT: Before setting the reel speed, check (if

mechanical reel drive) if the reel speed sensor is

“installed“ in the configuration info screen and adjust

the “Minimum reel speed (C)”. Select these items on

the InfoViewt monitor to adjust. Refer to “SECTION

- CONTROLS, INSTRUMENTS AND

OPERATION”, paragraph: “VI CONFIGURATIONS

AND CALIBRATIONS”, headed: “11.Header”.

For example:

If the Auto reel speed offset (E) = 0 km/h and the

ground speed (B) = 4 km/h (2.5 mile/h): This means

that the tip speed of the reel= 4 km/h. (2.5 mile/h)

NOTE: How higher the auto reel speed offset

setpoint, how higher the tip speed of the reel in

relation with the ground speed.

3-28

SECTION 3 - FIELD AND SITE OPERATION

To obtain a proper reel synchro control, proceed as

follows:

1. Set the reel speed synchronization engagement

tumbler switch 3 in the ON position.

2. Operate the combine in a section of the field that

best represents the overall crop with a minimum

ground speed of 1 km/h (.6 mph).

3. Adjust the reel speed with the reel speed

switches 1 and 2 to match with the combine

ground speed.

If you now change the combine ground speed, the

reel speed will change automatically according to the

ground speed change.

NOTE: On headlands or whenever, lifting the header

out of the operational zone

(disengaging of

hectare/acre counter), the reel speed will be

maintained until the header is lowered again.

3-29

SECTION 3 - FIELD AND SITE OPERATION

• The operator has not been turning the steering

wheel for at least two seconds.

• Press automatic header height control button (6),

the SmartSteert system goes into HHC mode

and becomes active and will steer the combine

along the selected edge of the crop.

If the SmartSteert symbol in the indicator bar

on the InfoViewt is appearing with a white

background means that the SmartSteert

system is activated (operational).

3-30

SECTION 3 - FIELD AND SITE OPERATION

The SmartSteert system is automatically switched

off from its activated mode when:

• the automatic header height control button (6) is

pressed two times.

• the ground speed is lower than 0.5 km/h

(0.32 Miles/h) or the combine is reverse driving.

• the operator is turning the steering wheel.

• the signal quality from the HGS sensor is too low

or no crop edge is detected or end of crop is

detected.

NOTE: In the enabled mode, the SmartSteert

system is not controlling the steering wheels
