Putting into service
Preparing the tractor
-
The tractor PTO stub must rotate at a speed of
1000 min
-1
.
The tractor must be equipped with:
- 2 double-acting hydraulic valves.
or
- 1 single acting hydraulic outlet.
Hitch pin parallelism.
Adjust tractor lift rods so that hitch pins are parallel to the
ground.
Check that the tractor's authorized gross
weight as well as its lift capacity and
maximum weight per axle are not surpassed.
The front axle load (1) must never, under any
circumstances, be less than 20% of the
tractor's unladen weight. Add ballast weights
to the front in order to preserve the steering
and braking efficiency.
The tractor must be fitted with lower link
stabilizers.
for easier attachment and pitch angle
adjustment, we recommend to use a hydraulic
top link.
In this case, an additional double acting outlet is
required.
