3. Select the speed range and gear.
Select a speed range which:
gives the optimum fuel consumption without overloading the engine and
the transmission.
allows the engine to operate comfortably at about 75% of its maximum
power.
You can select any speed range and gear you want, but if a gear within the
range of C4 and D5 is selected, automatics shift the gear to C3.
IMPORTANT: Use the creeper gear for slow driving speeds only. Do not use
it for bigger drafting force.
4. Move the power shuttle lever to either drive forward or reverse.
5. If you have started on a slope and kept the brake pedals pressed, release the
brake pedals.
The hillhold is activated and keeps the tractor stationary.
6. Adjust the driving speed with the drive pedal.
This deactivates the hillhold and you can start driving even uphill so that the
tractor does not move downhill at all. Keep an eye on the indicator lights and
gauges while driving.
NOTE: If the engine stops when driving, for example due to overload, you can
restart it without turning the ignition key to the OFF position first. However, if the
front linkage, PTO, U-pilot, hydraulics or cruise control were in use when the
engine stopped, they have to be restarted separately.

Transmission system

The tractor transmission system has six speed ranges and five Powershift
stages. These together give the tractor 30 forward and 30 reverse gears.
The speed ranges are named LA, LB, A, B, C and D. The speed ranges LA and
LB are called creeper speed ranges. The actual driving speeds achieved depend
on the engine speed and the tyres. The following table includes approximate
driving speeds for each speed range with the engine speed of 1400–2200 rpm
and 20.8-42 tyres.
