Tractor stability
Check the lifting capacity and the longitudinal stability of the tractor by means of the following formula. Add ballast at
the front if necessary.
To determine the total weight of the machine, add up the weight of all the components (see Chapter 3).

The front axle of the tractor is lightened according to the weight attached at the time of
coupling to the shredder. THE LOAD ON THE FRONT AXLE MUST BE AT LEAST 20% of
the total mass tractor/equipment ready to be used.
Check the lifting capacity and the stability of the tractor to avoid its tipping and/or losing

the grip of the steering wheels.
Lift the machine completely and check that the tractor does not pitch.
When the machine is at its maximum extension, check the stability of the tractor: open the arms slowly and keep
the shredding flail head as close as possible to the ground. If necessary, ballast the tractor rear wheel opposite the
extended arms.
Do not work with the arms extended while the tractor is sitting on sloping ground.
During transport, move the machine into the central position.
