4 . MAINTENANCE AND ADJUSTMENTS
4.10 Challenger MT500B EU
4.5.4 - Setting ground speed
To increase or decrease speed, both levers can be used.
The left-hand lever (Fig. 12) adjusts the speed by incre-
ments of 0.1 to 2 kph, depending on the length of time the
lever is activated.
The right-hand lever (Fig. 13) allows to adjust the transmis-
sion ratio more easily due to its progressivity. When de-
creasing the ratio, the tractor stops at 0 kph (dynamic stop).
The right-hand lever travels at varying increments depend-
ing on its position. It has 3 increment types (Fig. 14):
• Increments of 0.03 to 0.5 kph in brackets 1 and 4.
• Increments of 1 kph in brackets 2 and 5.
• Increments of 2 kph in brackets 3 and 6.
There is a mechanical stop when shifting to bracket 2 or
bracket 3.
NOTE: If speed regulation is active, pressing the lever
automatically deactivates it.
4.5.5 - Selecting Hare or Tortoise range
The "TECHstar CVT" transmission possesses 2 gear rang-
es. Each range is limited, as shown by the following table:
A button
4
on the right-hand console (Fig. 15) is used for
shifting Hare/Tortoise range. Shifting is possible while the
tractor is moving, but only from Tortoise to Hare range.
When shifting from Hare to Tortoise, the left-hand lever
(Fig. 12) must be in neutral position, or the clutch pedal
must be pressed down. The range is displayed on the in-
strument panel right-hand screen.
