Measure 1” (“B” dimension) back from the inner shaft universal joint shield and make a mark
at this location on the outer shaft shield.
•Remove shaft from tractor and gearbox shaft.
•Measure from end of inner shield to scribed mark (“X” dimension). Cut off inner shield at the
mark. Cut same amount off the inner shaft (“X1” dimension).
•Measure from end of outer shield to scribed mark (“Y” dimension). Cut off outer shield at the
mark. Cut same amount off the outer shaft (“Y1” dimension).
The PTO shaft maximum allowable length must, when fully extended, have a minimum overlap of
the profile tubes by not less than 1/3 the free length with both inner and outer profile tubes being of
equal length.
For minimum PTO shaft length, measure 1” (“B” dimension) back from universal joint shield to end
of outer PTO shaft shield.
4. OPERATING
Before operating the tiller, make sure you have read and understood the operating manuals of
the tiller, tractor, and PTO shaft.
DANGER
During operation, adjustment, maintenance, repairing or transportation of the machine, the
operator must always use appropriate Personal Protective Equipment (PPE).
Before starting work, ensure that all machine guards are in good conditions and fully
functional.
NOTE: Never attempt to adjust the rotary tiller while the tractor is running. Do not allow the tractor
engine or rotary tiller to bog down or stall. This causes undue wear and tear on the tiller and tractor.
If this continues to happen reduce ground speed and raise tilling depth of rotary tiller. Never attempt

10
to remove objects from the rotor bar until the tractor has been shut down and the tiller tines have
completely stopped.
4.1 RAISING PARKING STAND
1. Remove spring locking pin.
2. Slide parking stand and way up on tiller bracket.
3. Fasten with spring locking pin.
4.2. LOWER CLEVISES ADJUSTMENT
It is possible to adjust the lower hitch position loosening the bolts
and sliding the clevis. Tighten the bolts after making any
adjustment required.
4.3 SKIDS ADJUSTMENT
The working depth of the tiller is determined by the position of the side skids. It may be increased by
raising the skids and decreased by lowered them. It's important that both skids are adjusted at the
same height.
To adjust the working depth, perform the following steps:
•Lift the machine, put it safely on security stands, then switch the tractor engine off,
disengage PTO, set parking brake and off the ignition key.
•Loosen the bolt Ain the front of the skid.
•Loosen the bolt B and remove the bolt on the rear of the skid.
•Adjust the height of the skid through the holes, as desired.
•Tighten the bolts.

11
When finished, verify that both skids are at same level, and check if the
front of the tiller is leveled to the back, when lowered to the ground.
Adjust with the 3-point top link if necessary.
4.3. REAR BOARD ADJUSTMENT
The position of plank board is adjustable by varying the hole position
on shocker mounting plate (A). lowering the hole will increase
pressure of tension shocker assembly (B) on plank board which result
soil level compaction while upper hole position will reduce the
pressure.
To adjust the plank board position, perform the following steps:
Loosen and remove the bolt and nut of shocker holding clamp (C) adjust the clamp upper and
lower against shocker mounting plate (A) as required.
5. TRANSPORTING
To set the tiller for transportation, perform the following steps:
•Idle tractor engine, disengage tractor PTO, and wait for stopping of all rotating parts.
•Lift the tiller until the transport position, making sure the PTO shaft does not contact tractor
or tiller. A minimum gap of 2 cm should be leaved between the tubes and tractor and tiller.
•Lock the tractor lifting hydraulics, turn off the engine, set the parking brake, remove ignition
key, and get off the tractor.
•Adjust the parking stand to the highest position, through the use of relative retaining pin, to
prevent possible damage during transport. When driving on public roads, follow strictly all
local laws and traffic regulations
6. MAINTENANCE
6.1 SERVICE LUBRICATION
CAUTION
•The given frequencies are indicative and refer to normal conditions of use. They may
therefore be subjected to variations in relation to the type of service, in more or less dusty
environment, seasonal factors, etc.
•In the case of heavy-duty condition, the maintenance operation should obviously be more
frequent.
•Before injecting grease into the lubricators, the greasing points must be thoroughly cleaned
to prevent mud, dust or foreign bodies from mixing with the lubricants, thus reducing or even
annulling its lubricating effect.
•When topping up or changing the lubricant, always ensure that the oil is of the same type as
that used previously.

12
•Always keep oil and greases well away from children’s reach. Always thoroughly read the
warnings and precautions indicated on the containers.
•Avoid contact with the skin.
•Always thoroughly and fully wash after use. The utilized oils should be treated in compliance
with the current anti-pollution laws.
It is advisable to use SAE 140 EP Grade OIL or equivalent for the gear box unit and side
transmission. It is advisable to use high quality grease for all greasing points.
EVERY 8 WORK HOURS
•Grease the PTO Shaft cross journals.
•Check that the bolts fixing the hoe blades are well tightened.
EVERY 50 WORK HOURS
•Check the level of the oil in the gearbox or in the reduction unit and top up to the level mark
on the rod as necessary.
•Side Drive Transmission: Check the level of the oil in the side casing of the transmission unit.
•Add oil through the fill plug if necessary. It should flow from the level plug.
EVERY 200 WORK HOURS
•Change the oil in the gearbox or in the reduction unit and transmission casing by completely
draining of the old oil through the drain plug, under the reduction unit and through the
transmission drain plug.
6.2 BLADES REPLACEMENT
The Blades with which the rotary tiller is equipped can work soils of normal conformation. Check the
degree of wear and condition of the Blades each day. If the blades should accidentally bend (or
break) during work, they must be immediately replaced.
FIRST - IDENTIFY BLADES:
Remember to mount the new Blade in the same position as the old one. If several Blades must be
replaced, it is advisable to remove and assemble one Blade at a time to prevent positioning errors.
The tillers are normally equipped with 6 blades per flange.
SECOND - INSTALL NEW BLADES:
1. Raise tiller with a safe lifting device.
2. Put safety stands or blocks under tiller.
3. Stand facing rear of tiller and study placement of Blades.
4. Remove bolts, lock washers, and nuts.

13
7. STORAGE
1. It is advisable to proceed in the following way at the end of the season or if the machine is to
remain inactive for a long period of time:
a. Wash the implement, particularly removing any fertilizer and/or chemical products,
and then thoroughly dry it.
b. Carefully check for any damaged or worn parts and replace these if necessary.
2. Fully check screws or bolts, particularly those fixing the hoe blades.
3. Thoroughly lubricate the implement and lastly protect it with a plastic sheet. Store it in a dry
place. Careful compliance with these instructions will be all to the advantage of the user who
will be sure to use an implement in perfect conditions when work begins again. Remember
that the manufacturer is always at your disposal for any assistance or spare parts as may be
required.
