SET-UP
PTO SHAFT CONNECTION
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation
match those of the tractor. Carefully read the PTO shaft and tractor instructions.
Furthermore, accurately read the instructions of the manufacturer of the PTO shaft and of the
tractor.
Before starting any activity, make sure that the guards are installed on the power take off of the
tractor and PTO shaft. Make sure that they cover the PTO shaft throughout its length.
When fully extended, the plastic pipes must overlap
by at least 1/3 of the length of the pipes (LT). When
retracted, the minimum acceptable clearance is 2"
(picture 6).
Check that the PTO shaft minimum and maximum
length are within the parameters of the machine tractor
coupling.
Should problems arise, contact your dealer. After the
installation, anchor the PTO shield to the tractor and
machine using the special chains; make sure that it turns
smoothly. If the PTO shaft is equipped with safety
devices, e.g. torque limiters or free-wheel devices,
install them on the operative machine side. For the use
and maintenance of the PTO shaft, please refer to the
relevant manual.
SLIP CLUTCH DRIVE SHAFT
This tiller has a drive shaft with a slip clutch, which has been calibrated
for a certain overload. To adjust the clutch, tighten or loosen bolts equally.
Don’t over-tighten or clutch will lock and not slip under stress, which
could cause damage during operation. The clutch assembly should get
warm (normal temp. 104-122°F) under normal operation. If the clutch
gets extremely hot, this is a sign of slippage. If the machine sits for an
extended period of time with no usage, the bolts should be loosened and
the PTO engaged. This will allow the clutch discs to become free again.
After a few seconds, shut-off the tractor and retighten bolts equally.
Recheck clutch assembly for temperature after using in tilling application.
If it is too hot, the bolts need tightening. If it is too cool, loosen bolts.

SET-UP
COVER ADJUSTMENT
The rear cover can be adjusted in height to better compact
the ground and make it at. The adjustment can be made by
releasing chain A (picture 7) from upper hook B and inserting
it back to the needed height.
These operations shall be made only on working ground and
only after having stopped the engine, disengaged the power
takeo and pulled the parking brake. If necessary, lift the
machine from the ground but, in order to avoid risks for
people, place it on supports thus preventing any injuries that
might be caused by its sudden fall.
WORKING DEPTH ADJUSTMENT
The working depth of the equipment depends on the position of the lateral skids. If the skids
are raised, the working depth increases; if the skids are lowered, the working depth decreases.
To adjust the working depth, loosen nut A, B, and C
(picture 8) and adjust the skid height according to
the notches D.
When the adjustment is completed, tighten the
screws to the correct torque, according to the
values suggest in Torque Specications, page 5.
IMPORTANT: Make sure that the skids are set at
the same height on both sides.
These operations shall be made only on working ground and
only after having stopped the engine, disengaged the power
takeo and pulled the parking brake. If necessary, lift the
machine from the ground but, in order to avoid risks for
people, place it on supports thus preventing any injuries that
might be caused by its sudden fall.

MAINTENANCE
Maintenance is crucial for the working life and efciency of any agricultural equipment. If
the equipment is properly maintained and operated, a long working life and operator safety
are assured.
The maintenance intervals indicated in this booklet are provided as a mere reference and are
related to normal working conditions; changes may occur depending on the type of activities,
environmental dust, seasonal factors, etc.
• Before injecting lubricating grease into the grease ttings, clean
the ttings to prevent mud, dust, or any other foreign matter
from contaminating the grease and reducing the lubrication effect.
•When adding or changing the oil, use the same type of oil to
prevent mixing oils with different features.
•All maintenance activities must be carried out with the tiller
resting horizontally on the ground.
•After using the equipment for a few hours, make sure that all the
bolts (especially tine bolts) are tightened; regularly check all the
machine guards.
FIRST CHECK
•After 50 working hours, change the oil in the gearbox and make sure that all the screws and
bolts are tightened.

SPARE PARTS
The maintenance activities must be carried out
with the engine o, the power take o disengaged,
the parking brake engaged, and the equipment
placed on the ground.
BLADES REPLACEMENT
To assure the optimum efciency of the machine, make sure that the tiller blades are in a good
working condition and that their bolts are tightened; replace them if they are broken or bent.
The new parts must be installed in the original position.
Before replacing the blades, turn the tractor engine o,
pull the parking brake, disengage the power take o,
raise the tiller using the tractor lift, and install supports
to prevent accidental dropping of the machine.
Pay special attention to the bolts A on the blades (picture 14): the screw head must be placed
on the blade side, with the washer and the nut on the ange side, so that the bolts cannot
loosen while the equipment is being used. When several blades must be replaced, replace one
blade at a time, so that the initial helical layout is maintained.
