9.3 TROUBLESHOOTING HINTS FOR THE
TRACTOR OPERATOR/DRIVER
Insuffi cient depth
a) Check the positioning of the two depth skids or of the roller, if
present.
b) Move forward more slowly as the power of the tractor may be
insuffi cient.
c) If the earth is too hard a second or third hoeing may be neces-
sary.
d) If the hoe blades are rotating on top of the earth instead of cutting
into it, increase the working depth and proceed more slowly.
The earth is not broken up fi nely enough
a) Lower the levelling blade.
b) Reduce the tractor speed.
c) Don't work earth that is too wet.
d) In the machine fi tted with a levelling bar, raise or lower this so
as to keep the sods closer to the hoe blades
Clogging up of the rotor
a) The earth is too wet for hoeing.
b) Raise the levelling blade.
c) Reduce the tractor speed.
d) Reduce the number of hoe blades per fl ange from 6 to 4.
e) Avoid choeing where there is long grass and carefully clean
whatever debris has gathered on the supports on the sides of
the rotor to avoid overheating.
The machine bounces over the earth or vibrates
a) There are foreign bodies caught between the hoe blades.
b) The hoe blades have been incorrectly
not forming the helix shape or with the blunt edge placed to cut
into the earth fi rst instead of the cutting edge.
c) Worn or broken hoe blades.
d) The rotor is deformed because of blows to the central part
caused by foreign bodies present during hoeing.
e) Cardan shaft in wrong position (see Fig.4)
Other problems
The machine does not hoe to the same depth over the whole width
e.g. if it hoes too deeply on the right side shorten the right arm of
the lift bars and regulate the position of the right-hand skid.
Working a hill/slope
Where possible always try to «work up» the slope. If this is not
possible avoid hoeing along the contours of the hill and hoe up
and down the slope to avoid a terracing effect.
Practical notes
The hoed earth should be on the right of the driver.
The best system is to hoe alternate strips.
9.4 PARKING
WARNING
Comply with the following instructions in order to ensure that
the machine remains stable when released from the tractor:
1) Position the support foot as shown in the fi gure (1 - Fig.58)
2) Hold the cardan shaft with a suitable support (2 Fig.59).

10.0 MAINTENANCE
Here follows a list of various maintenance operations to be carri-
ed out periodically. Lowered operating costs and a longer lasting
seeding machine depend, among others, on the methodical and
constant observation of mese rules.
The maintenance periods listed in this booklet are only indi-
cative and are for on normal conditions on use, therefore be
varied depending the kind of service, the more or less dusty
surroundings, seasonal factors, etc. For more serious condi-
tions of service, maintenance will logically be done more often.
CRUSHING AND SHEARING HAZARD. POTENTIAL SERIOUS
INJURIES OR DEATH.
All operations must be carried out by expert personnel,
equipped with protective gloves, in a clean and dust-free
environment.
All maintenance operations must be carried out with the ma-
chine hooked up to the tractor, the parking brake engaged,
the engine off, the ignition key removed and the equipment
sitting on suitable supports on the ground.
