CAUTION: Avoid injury. Proper ballastings is required for safe operation of your tiller
IMPORTANT: Refer to the tractor operator manual for proper ballasting information and tire inflation
• A 540 rpm PTO
• Refer to the tractor operator is manual for correct ballasting and tire pressure, depending on installed
equipment.
Park vehicle safety
• Stop vehicle on a lever surface, not on a slope.
• Disengage PTO.
• Engage the park brake.
• STOP the engine.
• Remove the key.
• Before you leave the operator’s seat, wait for engine
and all moving parts to STOP.
Stay clear of rotating drivelines
Entanglement in rotating driveline can cause serious
injury or death:
• Wear close fitting clothing.
• STOP the engine and be sure PTO driveline is stopped

The shear pin, inserted in the PTO shaft, is equipped with
a safety bolt (A) that is set for an average force.
Whenever unduly resistant obstacles cause the bolt to

PTOshaftwithclutch(1150-1160-1160H-1250-
1260-1360 model)
The PTO shaft can be equipped with safety clutch to
protect the transmission components of the machine
from stress and/or excessive overloads.
The tilt of the PTO shaft must not exceed 10 degrees.
The clutch is already pre-adjusted for average stress. If it
slips too easily (and overheats), it will be necessary to
evenly tighten all the nuts (D) that retain the springs.
The clutch disks must be changed if the clutch still slips
after all the nuts have been tightened.
If the clutch does not slip, evenly unscrew all the spring
fixing nuts (D). Unscrew one turn at a time and check the
clutch after having worked about 300 meters. Repeat the
operationifnecessary, rememberingtounscrewoneturn
at a time. If the clutch maintains a temperature of about
40-50°C (104-122°F) degrees during work, this means
that it has been correctly regulated.
IMPORTANT:Neverfullytightenthenuts. Thiswould
voidthefunctionofthespringsand,subsequently,of
the clutch, thus damaging the transmission compo-
nents.

NOTE: This inspection must be performed at the
beginning of each new season.

OPERATING
Operate safely
• Protect your hands when you inspect or unplug the tiller. You may need gloves or tools, such as a
screwdriver or scraper. Be sure hardware is tight. Repair or replace damaged, badly worn, or missing
parts. Be sure guards and shields are in good condition and fastened in place. Make any necessary
adjustments before you operate.
• Clear work area of objects that you do not want tilled
into the ground or that might damage the tiller. Consider
the tilling area and set up a safe tilling pattern. Do not
till under condition in which traction or stability is
doubtful. Keep people and pets out of the work area.
Stop machine if anyone enters the area.
• If you hit an object, stop the machine and inspect it.
Make repairs before you operate. Keep machine
properly maintained and in good working order.
• DO NOT leave machine unattended when it is running.
• Only operate during daylight or with good artificial light.
• DO NOT let anyone, ESPECIALLY CHILDREN, ride
on machine or vehicle. Riders are subject to injury such
as being thrown off. Riders may also obstruct the
operator’s view, resulting in the machine being
operated in an unsafe manner.
• DO NOT let children or an untrained person operate
machine.
• DO NOT wear radio or music headphones while
operating the machine. Safe operation requires your
full attention.
• DO NOT operate the tractor and tiller when you are
tired or ill.
It is absolutely forbidden to stand between the tractor and the implement when maneuvering
the lift control from the outside.

The tiller unit can be shifted sideways in relation to the
three-points hicth. This makes the implement extremely
versatile during the various work conditions.
Use of the hexagonal drive shaft allows the tiller unit to
quickly slide, thus notably simplifyng the operation.

OPERATING
Tilling tips
Before You till:
• Pick up rocks and foreign objects.
• Mow tall weeds and grass to keep them from wrapping around tines or tine shaft.
• Check tines. Loose, bent, broken, or missing tines reduce operating efficiency. If necessary, replace
tines.
Test the soil by squeezing it in your hand. If soil forms a ball, it is too wet to till. If soil does not compress
easily or falls apart, it is ready to till.
DO NOT till when soil is wet. Wet soil will stick to the tines and tine shaft. Wet soil will also dry out and
become hard, making it hard to work with during the growing season.
During tilling
CAUTION: Never lower tiller into the ground while the tractor is turning.
• DO NOT back up or make sharp turn with tiller in ground.
• Move PTO switch lever to ON when tiller is out of the ground. Move tractor forward and lower tiller into
the ground.
• When you till hard ground or sod, till at a shallow depth on first pass. Increase depth on each pass.
• When tilling on a hillside:
- Work up the the slope, if possible.
- If lateral work cannot be avoided, work from the top to the bottom in order to limit any terracing effect.

Replacing tines
CAUTION: To prevent injury: Wear heavy gloves when replacing tines.
To get the best performance from your tiller:
• Replace badly bent, worn, or broken tines immediatly.
• Replace worn or broken hardware (see your Frontier dealer for correct hardware).
• MAKE SURE to replace tines on ONE spindle at time to keep spiral tine pattern.
• Tine cutting edge MUST BE facing forward in direction of tine rotation.

SERVICE
CAUTION: Make sure you block tiller before doing any service on the tiller.
• STOP engine.
• LOCK park brake.
• FIRMLY block tiller on horizontal surface.
Tines can be changed with the tiller mounted on tractor. Make sure you block the tiller before doing any
service on the tiller.
Tines
Before replacing tines make sure the tiller is firmly blocked.
The tines with which the rotary tiller is equipped can work soils of normal conformation. Check the degree
of wear and condition of the tines each day. If the blades should accidentally bend (or break) during work,
they must be immediately replaced.
First - Identify tines:
Remember to mount the new tine in exactly the same position as the old one (A). If several tines must be
replaced, it is advisable to remove and assemble one tine at a time in order to prevent positioning errors.
The tillers are normally equipped with 4 blades per flange.
Second - Install New Tines:
1. Raise tiller with a safe lifting device.

1. Put safety stands or blocks under tiller.
3. Standfacingrearoftillerandstudyplacementoftines.
4. Remove four bolts, lock washers, and nuts (C).
NOTE: Make sure to replace tines on ONE spindle at
a time to keep spiral tine pattern.
5. Remove left-hand tine (A) and right-hand tine (B).
6. Install new tines and fasten with bolts, lock washers,
and nuts (removed above).

Adjust depth control on tractor.
Raise leveling board.
TILLED SOIL TOO FINE
Use a faster tractor ground speed.
Lower leveling board.
TILLED SOIL TOO COARSE
Use lower tractor speed.
Wait until soil is drier.
TINES BALLING UP WITH SOIL
Raise leveling board.
Decrease tractor speed.
Ground too sticky for working.
CUTTING TOO DEEP ON ONE SIDE Tiller not level:
• Level tiller.
• Adjust depth control skid.
