Shifting the AutoQuad™ PLUS Transmission

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). AutoShift 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 start driving, 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 engine is running and a range has been selected, actuating the reverse drive lever will cause the tractor to start moving.

To change the ranges, the clutch pedal has to be depressed or the hand clutch button has to 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 and then engage park lock at the range-shift lever (A).

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

NOTE: If shift lever (A) is moved to park and 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 starts, an acoustic alarm is given and a corresponding message appears on the digital display.

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 stopped. 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, even though the reverse drive lever is in the forward or reverse position. A message appears on the digital display. To make the tractor move, set 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.

Optimal gear-shifting for driving under load (transport) with speed matching disabled:

1. Select a range suitable for starting up under the respective 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.

Optimal gear-shifting for driving under load (transport) with speed matching enabled:

1. Select a range suitable for starting up under the respective 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), SoftShift is deactivated.

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.

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.

Come-Home Mode

LX234748-UN-30SEP15

To do this, stop the engine, remove connector (A) (fuse/relay box), rotate it 90° to the right and reinsert it.

The wording Come Home must be at the top.

Refer also to fuses and relays (LCS) with PowrQuad™ transmission in the Service Section - if necessary.

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.

Automatic gear shifting

LX1056686-UN-09JUL12

LX1056716-UN-09OCT12

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 accelerator pedal 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, AutoShift 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	4th gear	4 sectors
2x briefly in succession	3rd gear	3 sectors
3x briefly in succession	2nd 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).
