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 A in 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.
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.
4.4. 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.

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 operate 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 to remove objects from the rotor
bar until the tractor has been shut down and the tiller tines have completely
stopped.

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.
• 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.
10
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 exactly 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 in order 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.
7. STORAGE
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:
• Wash the implement, particularly removing any fertilizer and/or chemical products, and
then thoroughly dry it.
• Carefully check for any damaged or worn parts and replace these if necessary.
