AutoPowr™ — Controls

The AutoPowr™ transmission provides infinitely variable ground speeds in forward travel from 50 meters per hour (164 feet per hour) to 50 km/h (31 mph). In reverse travel, the transmission provides infinitely variable ground speeds from 50 meters per hour (164 feet per hour) to 30 km/h (18.6 mph). Maximum speeds may vary slightly due to tire size.

Reverse drive lever

LX1037182-UN-06JUN06

A — Neutral Position
Disengages park lock allowing tractor to roll, but does not transmit power to the wheels. N appears on the corner post display.

B — Forward Travel
In this position, power is transmitted to the wheels to allow forward travel. F appears on the corner post display.

C — Power Zero
Hand-held zero position is used to temporarily hold tractor stationary on a relatively flat surface.

D — Reverse Travel
In this position, power is transmitted to the wheels to allow reverse travel. R appears on the corner post display.

E — Park
In this position, park lock is applied to hold the tractor stationary and prevent it from rolling away. P appears on the corner post display.

F — Center Park
Scrolls through set speeds on corner post display continuously, while tractor is not moving.

To drive the tractor, move the lever to forward (B) or reverse (D). If the lever is moved from forward or reverse back to the center park position (F), the tractor will continue to roll and the transmission goes to its Power Zero mode. Ten seconds after the tractor stops rolling, park will automatically engage. If the lever is moved from Forward or Reverse directly to Park position (E), the tractor will brake to a stop using the transmission. Park will then engage. Remember to actuate the brake pedals as well when driving downhill.

If the lever is moved from forward or reverse to the Power Zero position (C), the tractor will continue to roll but it will not be braked by the transmission. When the tractor is stationary, power remains at the transmission. For Power Zero, the lever must be held firmly in this position. If the lever is released from the Power Zero position, it will automatically go to the center park position (F).

When the tractor is stopped, move the lever back to the corner park position (E). If the lever is moved to neutral (A), the direction clutches are opened and there will be no power in the transmission. The tractor may roll away.

Speed control lever

LX1037183-UN-10OCT05

A - Speed Control Lever

B - Speed Wheel (for setting maximum speed)

1 - Speed Band 1

2 - Speed Band 2

Travel speed is regulated using the speed control lever. Two speed bands are available.

Speed band 1 allows a maximum forward speed setting of 20 km/h (12.4 mph). Speed band 2 allows a maximum forward speed of 40 km/h (25 mph) or 50 km/h (31 mph).

NOTE: The maximum speed depends on the tire size. See also Section 65.

The maximum speed in band 1 is always the minimum speed in band 2. This means that when changing the band, there is no change in speed.

The maximum speed in a speed band is adjusted using speed wheel (B). See AutoPowr™ Settings on the following pages for details.

The maximum speed of a band is reached with the engine at full throttle and the speed control lever at the end of its travel in the speed band (provided tire dimensions match the set values precisely). If the accelerator pedal is not at the end of its travel, the tractor will move at a corresponding speed (not proportional). If the speed control lever is not at the end of its travel in a speed band, the tractor will similarly operate at a corresponding speed.

Speed wheel (B) does not have a stop and can be infinitely adjusted. It makes a change in relation to the previous setting. If the maximum speed setting is changed with wheel (B) while the tractor is moving, the change is always based on the last setting. Turning the speed wheel will directly increase or decrease the last maximum speed setting. Any changes are stored by the tractor's electronics.

Creeper

If you chose a forward speed of lower than 2 km/h (1.24 mph) in band 1, the tractor will automatically shift to creeper mode. The possible minimum travel speed is 0.05 km/h (0.03 mph).

The maximum speed in band 2 is 2.5 times higher than in band 1. In both speed bands, maximum speed in creeper mode is not more than 2.5 times higher than the minimum speed. For example, if a maximum speed of 0.50 km/h (0.33 mph) is set in band 1, the minimum speed will be 0.20 km/h (0.12 mph).

At speeds below 0.6 km/h (0.37 mph), changing engine speed does not have any effect on travel speed.

If, in creeper mode, you use the speed wheel to increase speed while the tractor moving in band 2, the following occurs:

• If the speed selected is below 10 km/h (6.2 mph), the transmission remains in creeper mode. This means the originally set values will apply on changing back to band 1. Speed band 1 will flash on the digital display.
• Creeper mode also remains in effect if the 10 km/h (6.2 mph) speed is temporarily exceeded and then reduced to under 10 km/h (6.2 mph) before returning to band 1.
• Creeper mode will be ignored if the 10 km/h (6.2 mph) speed is exceeded and band 1 is re-engaged. The forward speed band 1 is automatically set to 1.24 mph (2 km/h).

Accelerator pedal and hand throttle

LX1037184-UN-10OCT05

A - Hand Throttle

The signal used for control is always the signal that requests or commands the higher engine speed.

If the accelerator pedal or hand throttle is moved to command a higher engine speed, engine speed increases. In ECO mode, once the set ground speed has been reached, the engine speed is reduced again (load-dependent).

If the reverse drive lever is set to forward or reverse, you can accelerate the tractor to the set speed using the accelerator pedal or hand throttle. The immediate travel speed is directly dependent on the setting of the accelerator pedal or hand throttle. The engine speed is only indirectly affected by the position of the accelerator pedal.

When the accelerator pedal or hand throttle are activated, the values set in the CommandCenter™ for automatic control and engine-speed limitation are always taken into account. For example, the value set for engine-speed limitation is not exceeded, even at full throttle. In Eco mode, the engine turns only as fast as needed, even if the operator applies full throttle.

Brake pedals

LX1024390-UN-03JUL00

A - Brake Pedals

If both brake pedals are depressed when driving the tractor, the speed will be reduced or the tractor stops. Due to the automatic clutch function, there is no need to depress the clutch pedal when braking.

When the brakes are released again, the tractor automatically accelerates up to the speed currently commanded by the hand throttle or accelerator pedal.

The higher the engine speed, the greater is the force required at the brake pedals to stop the tractor.

Clutch pedal

The clutch pedal normally does not need to be depressed to stop the tractor. If the clutch pedal is depressed, the corresponding clutch signal has priority over other commands.
