macchine agricole
Cut plants shredded to much
▪
Slightly lift the cutter from the ground, adjusting the height with the wheels (the blades of the cutter must not touch the
ground).
▪
Increase the ground speed.
Cut plants not shredded enough
▪
Slightly lower the machine towards the ground.
▪
Reduce the ground speed.
▪
Do not work in soil that is too wet.
Rotor clogged
▪
Soil too wet to work.
▪
Raise the machine from the ground.
▪
Reduce the ground speed.
▪
Do not work where the grass is too tall. If necessary, remove any material that has built up at the sides of the rotor to pre-
vent overheating.
The machine jolts over the ground or vibrates
▪
Foreign bodies locked between the knives.
▪
Knives incorrectly mounted without the helical arrangement or with edges that dig into the ground.
▪
Worn or broken knives.
▪
Rotor misshapen owing to blows received during work from foreign bodies in the central part.
Other faults
▪
The machine fails to work evenly along its width, shredding either too much or too little on one side, for example on the
right: shorten the right link.
Work on hilly ground
It is advisable to proceed «upwards» in the direction of the slope. Particular attention should be paid since, owing to the nature of
the ground, the stability of the tractor could be compromised or it could slip sideways.
Winter periods
It is inadvisable to work with the machine during cold periods, when the temperature drops below 0°C (zero degrees centigrade),
because the tines become sensibly more fragile. Moreover, when the weather is cold, the machine must be allowed to idle for a
few minutes with the PTO at half rate so as to allow the lubricants and transmission components to warm up.

4.5 TOOLS

The knives with which the machine is equipped are suitable for work with soil/plants of normal conformation. Check their condi-
tion each day to make sure they are not worn. If they should accidentally bend (or break) during work, they must be immediately
replaced and mounted in the identical position.
Proceed in the following way to replace the tools:
▪
Park the tractor on a flat surface with the machine hitched, then raise the machine with the power lift
▪
Insert two strong bearing stands at the sides of the machine to protect yourself should it fall
▪
Lower the machine on to the stands, turn off the tractor engine and apply the parking brake

4.6 STOPPING THE MACHINE

At the end of the job, the operator must:
▪
Disengage the tractor PTO
▪
Lower the machine to the ground
▪
Stop the tractor and engage the parking brake
▪
Make sure that all parts of the machine have come to a standstill
Only after the above mentioned operations have been carried out may the operator leave the tractor unattended.
