4 . MAINTENANCE AND ADJUSTMENTS
4.18 Challenger MT500B EU
4.5.11 - "ParkLock" electrohydraulic brake
A Fig. 27: A control located to the left of the steering wheel
allows the operator in the driver’s seat to control the "acti-
vated" and "deactivated" ParkLock positions.
IMPORTANT: If the tractor must be towed, refer to the
specific procedure in section 4.18.
Activating the "ParLock":
- the PowerShuttle lever must be in neutral position,
- the control (A) pushed towards the steering wheel
(closed padlock symbol).
The "ParkLock" is engaged.
NOTE: The electronic control ensures that the "Park-
Lock " is engaged as soon as the ground speed drops
below 1 kph. The indicator light on the instrument
panel comes on and the "P" symbol appears on the dig-
ital display.
Deactivating the "ParkLock":
- The control (A) must be pulled outwards (open padlock
symbol).
IMPORTANT: For the "ParkLock" to disengage after
engine start-up, the electronic control must record a
switch of the control (A) from the closed padlock posi-
tion to the open padlock position. If not, the "ParkLock"
remains engaged, even if the control is in the open pad-
lock position.
DANGER: Engage the control into locked position
(closed padlock symbol) before leaving the driver’s
seat with the engine running.

IMPORTANT: Before towing the tractor refer to the tow-
ing instructions section 4.18.
