after the soil has been worked. When the rear bar is raised, the clods are no longer broken up and the soil is no longer levelled.
4.7.1 USEFUL TIPS
Here are a few useful suggestions on how to resolve some of the problems that may occur during work.
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 32°F (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.
4.8 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.
DANGER
Tool replacement is a dangerous operation.
Proceed in the following way to replace the hoe blades:
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
▪
Lower the machine on to the stands, turn off the tractor engine and apply the parking brake
