4.5.2 - Use
There are no mechanical speeds like on a standard tractor.
4.5.2.1 - Selecting direction of travel
The “TECHstar CVT” transmission possesses a user inter-
face and a specific display screen. The PowerShuttle lever
(Fig. 8) controls direction of travel, and speed increase and
decrease.
Move the left-hand lever in the required direction of travel.
The corresponding symbol is displayed on the instrument
panel right-hand screen, as shown in the following table:
When the tractor is operating, the direction is always
changed with the left-hand lever (Fig. 8). To start the tractor
moving (forward or reverse travel), the correct transmis-
sion ratio must be selected.
4.5.2.2 - Fast Shifting
When changing the direction of travel, the tractor decreas-
es to a halt, then accelerates in the opposite direction.
Shifting is inhibited but not blocked when the following
functions are active:
• the underspeed supervisor
• the turbo clutch function
During tractor movement, if the clutch pedal is activated,
the transmission ratio is decreased until speed is zero.
The armrest lever (1 Fig. 9) also controls speed increases
and decreases depending on the direction of travel.
