Warning
: make sure that the safety device only
allows the engine to start when the gearshift,
reverse shuttle and PTO levers are in neutral
position. Never ever cut out the safety device. If
it fails to operate regularly, have it adjusted by
specialized personnel.
Operation
Gearbox
Gearbox and speed range selector: 12 forward
speeds - 4 reverse speeds
The gearbox and speed range selector are controlled
separately by means of two levers. The gearshift lever
is on the right while the speed range selector is on the
left.
The gearshift selects four gear ratios (1, 2, 3, 4).
The speed range selector supplies three forward
ranges: low, standard, high, and one reverse range for
each gear ratio.
To change from one range to the other, disengage the
clutch, stop the tractor and shift the speed range
selector lever.
To change from one gear to the other within the same
speed range (including the reverse), simply operate the
gearshift lever without stopping the tractor since the
gearbox is the synchromesh type.
The speed must be chosen according to the job in
hand, the type of implement used and the soil
conditions.
Always choose a gear that enables the engine to work
with a certain reserve, so that any extra work-load can
be absorbed by the engine itself.
With the engine at maximum power, the available
speed ranges are:
Low Range:
- Four gears from 1.6 to 4.9 Km/h
Standard Range:
- Four gears from 4.0 to
12.2 Km/h
High Range:
- Four gears from10 to 29.3 Km/h.
Reverse:
- Four gears from 4.5 Km/h.to
13.2Km./h.
The tractor can be equipped with different types of
gearbox on request. Consult the Optionals chapter.
