PTO shaft
The PT O shaft, supp lied with the machine, is of standard
length.
Therefore it might be necessary to adapt the PT O shaft.
In that case, before doing anything, consult the Manufacturer for the eventual adaptation.
When th e PTO shaft is fully e xtended, th e two tubes must
overlap by at least 15 cm (A). When fully inserted, the
minimum play must be 4 cm (B).

CAUTION: If the implement is used on
another tractor, always check the that the
guards completely cover the rotating parts
of the PTO shaft.
Installing - Page 12

INSTALLING
PTO shaft with shear pin (1142 model)
The shear pin, inserted in the PT O shaft, is equipped with
a safety bolt (A) that is set for an average force.
Whenever unduly resistant obstacles cause the bolt to
shear, it must be replaced by a new bolt.
PTO shaft with clutch (1149-1157-1165-1265
model)
The PTO shaft can be equipped with safety clutch to
protect the transmission components of th e machine from
stress and/or excessive overloads.
A
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 spring.
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
fi xing nuts (D). Unscrew one turn at a time and check the
clutch after having wo rked about 300 meter s. R epeat the
operation if necessary , remembering t o unscrew one turn
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: Never fully tighten the nuts. This would
void the function of the springs and, subsequently,
of the clutch, thus damaging the transmission components.
D
NOTE: This inspection must be performed at the
beginning of each new season.

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 effi ciency. 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 t ill when soil is wet. Wet soil will stick to the tines and tine shaf t. 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 for ward and lower tiller into
the ground.
• When you till hard ground or sod, till at a shallow depth on fi rst pass. Increase depth on each pass.
• When tilling on a hillside:
- Work up the the slope, if possible.
- If la teral work ca nno t be avoi ded , work from t he top to the b ottom in ord er to limit any terracing ef-
fect.

)
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 t iller 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 fi rmly blocked.
The tines with which the rotary tiller is equipped can work so ils of normal co nf ormation. Ch eck the deg r ee
of wear and co ndition of the tines each day. If the blades should accide ntall y be nd (o r br eak) during w ork,
they must be immediately replaced.
First - Identify tines:
Remember to mount the new tine in exactl y 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 fl ange.
Second - Install New Tines:
1. Raise tiller with a safe lifting device.
1. Put safety stands or blocks under tiller.
3. Stand facing rear of tiller and study placement of
tines.
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).
NOTE: Two bolts go in from each side. Refer to sketch
at right.
7. Tighten bolts.
CAUTION: The heads of the bolts fi xing the
hoe blades in place must be on the side of
the hoe blades themselves, while the nut
with relative washer must be on the fl ange
side (B). Tighten bolts to 91 Nm (67 lb-ft).
