• Release the “Park Lock” parking brake. For this pur-
pose:
- take off the spacer (Ref. 4 Fig. 78) after removing the
screw ref. 5,
- refit and tighten the screw Ref. 5 (Fig. 79).
4.18.1 - Limp home mode
DANGER: When the tractor is stopped, the
gear range must be in neutral position (mid-
dle position) and the brake must be engaged.
CAUTION: Once the tractor is started, the
transmission is driven totally by meshing if a
gear range (hare or tortoise) is engaged. Press
down the clutch pedal, because any transmis-
sion ratio can be selected.
If the transmission ratio control is not possible due to a
breakdown, the tractor can be driven mechanically using a
limp home lever.
Maximum speed in the “Hare” range is 34 kph in forward
position and 25 kph in reverse position. For the “Tortoise”
range, maximum speed is 15 kph in forward position and
11 kph in reverse position.
• Stop the engine if it is running.
• Open the cover located on the cab floor (right-hand side)
(Fig. 73).
• Remove the protective shield (Fig. 74 and Fig. 75).
• Position the limp home lever on the range control (Ref. 2
Fig. 80) and select the limp home range:
- clockwise direction, tortoise range,
- anti-clockwise direction, hare range.
NOTE: The maximum speed when shifting range is 2
kph.
IMPORTANT: When changing range, only use the sup-
plied limp home lever, because the coupling mecha-
nism in the control unit could be damaged (maximum
allowed torque 10 Nm).
• Start the tractor while pressing down the red button
(limp home button) (Fig. 81).
