A - Range Shift Lever

B - Gear-Shift Buttons

C - Hand Clutch Button

D - Automatic Button

E - Gear Shift Switch (Extra)

F - Reverse Drive Lever

Gears are shifted by means of range shift lever (A), gear shift buttons (B) - or switch (E) - and reverse drive lever (F). Automatic selection is activated and de-activated by means of button (D). The hand clutch is operated by means of button (C).
Before starting the engine, move reverse drive lever (F) to its neutral position. To drive, first move range shift lever (A) to the desired range and then move the reverse drive lever to the desired direction of travel.

CAUTION: If the reverse drive lever is actuated when the engine is running and a range is selected, the tractor will start to move.

To change the ranges, the clutch pedal must be depressed or the hand clutch button must be actuated. There is no need to actuate the clutch to shift gears or to change the direction of travel.
To park the tractor, move reverse drive lever (F) to its neutral position, then engage park lock at the range shift lever (A).

IMPORTANT: Engage park lock only when the tractor is stationary.

NOTE: If shift lever (A) is moved to park when reverse drive lever (F) is not in neutral, an audible alarm is triggered and the blue INFO light comes on. When the engine shuts off, the reverse drive lever remains in its selected position but the transmission shifts into neutral.

If the reverse drive lever is not in neutral when the engine is started, an audible alarm is triggered and the relevant message appears on the digital display to alert the operator.

If the reverse drive lever is moved out of neutral while park lock is engaged, an audible alarm is triggered and the blue INFO light comes on. To make the tractor move, first put the range shift lever in a range and then move the reverse drive lever from neutral to the desired position.

Hand clutch

Press button (C), the clutch separates. Ranges may be selected or the tractor can be halted. Release button (C), the clutch engages with modulation. On tractors equipped with a seat switch (operator presence switch), the following applies:
If, within the last 3 seconds before the button is released, there was no weight on the seat and no actuation of the clutch pedal or brake pedal, the tractor does not move, although the reverse drive lever is in the forward or reverse position. A message appears on the digital display. To make the tractor move, move the reverse drive lever to neutral and then back into the desired direction.

NOTE: The hand clutch is not suitable for creeping up to an implement.

The hand clutch can be activated and de-activated at address PTQ167. See Customization in Operation and Entering Diagnostic Addresses Using Digital Display (Customer Level), Section "Diagnostic Trouble Codes and Customization".

Optimum gear-shifting for driving under load (transport) with speed matching deactivated:

1. Select a range suitable for driving under load.
2. Engage the first gear.
3. Drive and shift up through the ranges until the top range is reached.
4. Shift up through the gears.

Optimum gear-shifting for driving under load (transport) with speed matching activated:

1. Select a range suitable for driving under load.
2. Engage the first gear.
3. Drive and shift up through the gears until the top gear is reached.
4. Select the next range; speed-matching automatically selects the gear that corresponds to travel speed.
5. Shift up through the gears and change ranges until desired travel speed is obtained.

Cold-weather operation

If the oil is cold (0°C, 32°F), it may affect how the reverse drive lever operates. At temperatures below -10°C (14°F), it may take longer to change the direction of travel. Below +5°C (41°F), the automatic softshift is de-activated.

In certain circumstances, the reverse drive lever may have to be actuated several times before the tractor starts to move. When the oil has had time to warm up, operation becomes normal again.

Come-home mode

Under certain circumstances, the tractor can still be driven in come-home mode even if there is an electrical fault in the transmission.

To do this, stop the engine, remove connector K01/04 (relay box) and re-install it at a position 90° from its original position. The wording Come Home must be at top.

NOTE: In the come-home mode, engine speed is limited to 1500 rpm and only the first gear in each range is available. The hand clutch is NOT available.

Restriction in the event of a missing speed signal

If the control unit notices that the speed signal is missing, only the first three gears in each range are available.

Automatic gear shifting

D - Automatic Button

E - Automatic Icon

F - Gear Indicator

G - Sector Icon for Highest Gear

Automatic gear-shifting is selected by pressing button (D) once; icons (E) and (G) appear on the display together with the current gear (F).

The gears in each range are shifted in relation to the position of the hand throttle or foot throttle as soon as engine speed reaches a maximum or minimum value. The different operating modes can be set via a potentiometer (see "AutoQuad™ PLUS Transmission — Settings" on the following pages).

The following operating modes are available:

• Eco mode

• Power mode

• Intermediate settings

IMPORTANT: "Eco mode" is suitable ONLY for light work in the field and for driving on roads when the load being pulled is not heavy.

The automatic function can be deactivated by pressing button (D) once again or by selecting a gear manually.

Programmable highest gear in automatic gear shifting

NOTE: For programming, automatic gear shifting must be switched off.

In addition to activating the automatic gear-shift function, button (D) may be used to determine the highest possible gear. The following applies:

Press button (A)	Highest gear	Sector icon
1x	Fourth gear	4 sectors
2x briefly in succession	Third gear	3 sectors
3x briefly in succession	Second gear	2 sectors

This setting is lost as soon as automatic gear shifting is switched off.

In the illustration, the highest gear (G) is 3rd (three sectors light up).
