ATTACHMENT TO THE TRACTOR
Carefully read this instruction manual and the manuals of the tractor and PTO shaft manufac-
turer. All tillers are built to be attached to any tractor equipped with a three point hitch of the
correct category and with suitable ball ends.
Before attaching the equipment to the tractor, make sure that the ground is smooth and flat and
that nobody is standing between the tractor and the tiller; slowly move the tractor towards the
tiller by aligning the tractor lower lift arms with the two tiller coupling side pins; turn the engine
off and pull the brake.
It is possible to adjust the attachment position
releasing the bolts B. (picture 1) and modifying
the position of the plates A. Tighten the bolts
after making any adjustment.
picture 1
After adjusting the couplers, connect the lower lift arms by removing the lynch pins from the
pins located on the hitch brackets, inserting the lift arm pins through the hitch block and ball
ends and secure them by means of the pins which were previously removed.
Connect the tractor top link to the top mast by
removing the pin located between the two plates,
inserting the top link and securing it by means of
the pin.
Adjust the top link so that the upper part of the
frame is parallel to the ground.
Block all the linking parts by means of the sway
chains or arms.
Make sure that the central unit axis (gearbox
assembly) is parallel to the ground, thus minimiz-
ing the stresses on the power take off and increas-
ing the working life of the equipment.
picture 2
After executing all the above-mentioned activities,
make sure that all the nuts and bolts are tightened.

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 min. acceptable clearance is 2 inches (picture 3).
picture 3
Check that the PTO shaft min. and max. 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.
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.
Make sure that the skids are set at the same height on both sides.
picture 4
To adjust the working depth, loosen and remove
nut A(picture 4) and adjust the skid height
according to the holes B. When the adjustment
is completed, tighten the screws.

SET-UP

picture 5
LEVELING BOARD ADJUSTMENT
The height of the rear leveling board can be
adjusted, making the ground more compact
and smooth. Release the chain A from the
bracket B (picture 5), and re-engage it
according to the desired working height.
These activities must be carried out with the engine off,
the power take off disengaged and the hand brake
applied. If needed, lift the equipment and place it on sup-
ports, thus preventing any injuries that might be caused
by a sudden fall of the equipment.
CHAIN ADJUSTER
The B tillers are equipped with a self-loading chain drive system (picture 6).
The setting of the system is made during assembly; any adjustments when using the
machines, must be carried out by an authorized dealer or work shop.
picture 6
START UP
After carrying out these adjustments, the equipment is ready for use. When at the working
area, do not start the power take off with the tiller in working position in the ground. Be
sure to lift it by a few centimeters using the tractor lift. Start the engine, engage the power
take off, lower the equipment to its working position and start.

SET-UP
ASSEMBLING B SERIES 3-POINT HITCH
STEP 1: Install the top mast to the tiller main frame as shown.
STEP 2: Install the top link bracket to the top mast with the hole in the highest position
as shown.
STEP 3: Install the bottom link brackets with the holes facing down. This gives you
the standard A.S.A.E. dimension of 18" if the tractor does not have a quick
hitch.
STEP 4: If the tractor has an A.S.A.E. quick hitch, place the bottom brackets with
the holes in the high positions to obtain the correct spacing to tractors with
quick hitches.
NOTE: It is necessary to order a 3 bushing kit - part number 883303 - to
make the tiller A.S.A.E. quick hitch compatible.

ROAD TRANSPORT
With reference to road transport, follow local traffic regulations.
SHUT DOWN
The following activities are recommended if the tiller will not be used for a long period of time:
1 Clean and dry the equipment.
2 Inspect the equipment and replace the damaged or worn parts if necessary.
3 Tighten all the screws and nuts.
Lubricate and cover the machine with a tarpaulin and store it in a dry place.
MAINTENANCE
Maintenance is crucial for the working life and efficiency 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.
eBefore injecting lubricating grease into the grease fittings,
clean the fittings to prevent mud, dust, or any other
foreign matter from contaminating the grease and reducing
the lubrication effect.
eWhen adding or changing the oil, use the same type of oil
to prevent mixing oils with different features.
eAll maintenance activities must be carried out with the tiller
resting horizontally on the ground.
eAfter 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
eAfter 50 working hours, change the oil in the gearbox and make sure that all the
screws and bolts are tightened.
EVERY 8 WORKING HOURS
eGrease the PTO shaft crosses.
EVERY 50 WORKING HOURS
eRemove the cover (A - pict. 7, pg. 13) and grease the rotor bearing inside.
eCheck the oil level in the case/bevel gear pair (A- pict. 8, pg. 13) by removing
gearbox's upper oil plug (A- pict. 8, pg. 13); oil level should be contained between
the 2 nicks of MIN & MAX of the dip stick oil plug (B- pict. 8, pg. 13). If needed add
SAE EP 80W90 oil.
eCheck the oil level in the side transmission (A- pict. 9, pg. 13). If needed add
SAE EP 80W90 oil.
eMake sure that all the screws and bolts, especially on the blades, are tightened.
EVERY 500 WORKING HOURS
eChange the oil of the case/bevel gear pair, side transmission and rotor support; use
SAE EP 80W90 oil. Contact the closest dealer for this maintenance activity.

Page 13
MAINTENANCE
The old oil must be disposed of in compliance with the local
laws where these activities are carried out; do not spill or
dispose of waste oil on the ground.
The maintenance activities must be carried out with the
engine off, the power take off disengaged, the parking brake
engaged, and the equipment placed on the ground.
BLADES REPLACEMENT
To assure the optimum efficiency of the machine, make sure that the tiller blades are in a
