SET UP
ATTACHMENT TO THE TRACTOR
Carefully read this instruction manual and the manuals of the tractor and PTO shaft manufacturer.
All Phoenix tillers are built to be attached to any tractor equipped with a three point lift 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 lifter 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 3) and modifying the
position of the plates A(on the tillers T5, T10, T15, T20). Tighten the bolts after making any
adjustment.
On the tillers T25, T30 it is possible to change the lower position of the floating brackets by
inserting the pin Ain the lower hole B, as shown in picture 4, or do the opposite.
picture 3 picture 4
A
B
After adjusting the couplers, connect the lower arms by removing the catch pins from the pins
located on the hitch blocks, 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 third upper
point 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 th
e
frame is parallel to the ground.
Block all the linking parts by means of the swa
y
chains or arms.
Make sure that the central unit axis (case/bevel
gear pair) is parallel to the ground, thus
minimising the stresses on the power take off and
increasing the working life of the equipment.

Unifarm Machinery Corporation
PO Box 38, Wilson, NC, U.S.A.
page 13
After executing all the above-mentioned activities, make sure
that all the nuts and bolts are tightened.
CONNECTION TO THE PTO SHAFT
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 1-2 cm (picture 6).
picture 6
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.

page 14
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.
To adjust the working depth on the T5, T10, T15, T20 tillers loosen and remove nut A(picture 7)
and adjust the skid height according to the holes B. When the adjustment is completed, tighten the
screws.
To adjust the working depth on the T25, T30 tillers loosen nut A(picture 8) adjust the rod Buntil
you reach the requested height. When the adjustment is completed, tighten the screws.

picture 9
DRAG BOARD ADJUSTMENT
The height of the rear drag board can be adjusted,
making the ground more compact and smooth. Release
the chain A (picture 9) and re-engage it at the desired
height B.
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 supports, thus
preventing any injuries that might be caused by a sudden fall
of the equipment.

page 15
GEARBOX
picture 10The T25, T30 tillers are equipped with a gearbox and it is
possible to change the rotor speed independently from
the speed of the tractor’s PTO.
High speed improves the soil working, but rotating parts
wear more quickly.
To change the speed on the T25, T30 tillers, remove the
cover A(picture 10) of the box and invert the gears B
and Cat the inner side; it is possible to obtain other two
speeds by replacing the fixed gears with the ones placed
on the cover.
For the gearbox speed refer to the labels on the machine.
Adjust the gearbox with the engine shut off, the power take
off disengaged, the parking brake engaged, and the
equipment resting on the ground.
CHAIN ADJUSTER
On the T5, T10 tillers are equipped with a chain drive, the chain adjustment is made during
assembly. Any adjustments when using the machines, must be carried out by an authorized dealer
or work shop.
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 centimetres using the tractor lift. Start the engine, engage the power take off, lower the
equipment to its working position and start.
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:
1Clean and dry the equipment.
2Inspect the equipment and replace the damaged or worn parts if necessary.
3Tighten all the screws and nuts.

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.
-Before 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.
-When adding or changing the oil, use the same type of oil
to prevent mixing oils with different features.
-All maintenance activities must be carried out with the
tiller resting horizontally on the ground, with the engine
off and not overheated.
-After 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
-After 50 working hours, change the oil in the gearbox and make sure that all the screws and
bolts are tightened.
EVERY 8 WORKING HOURS
-For the T10 tillers grease the rotor support through the grease fitting A(picture 11).
-Grease the PTO shaft crosses.
EVERY 50 WORKING HOURS
-Check the oil level in the case/bevel gear pair by removing gearbox's upper oil plug (A- picture
14); oil level should be about at half of gearbox. If the model is equipped with dip stick oil plug
(B- picture 12), make sure that the oil level is contained between the 2 nicks of MIN & MAX.
-Check the oil level in the side transmission (A- picture 13) and in the T15, T20, T25, T30
tillers check the oil level in the rotor support (A- picture 14). If needed add SAE EP 80W90 oil.
-Make sure that all the screws and bolts, especially on the blades, are tightened.
EVERY 500 WORKING HOURS
-Change the oil of the case/bevel gear pair, side transmission and rotor support (T15, T20, T25,
T30); use SAE EP 80W90 oil. Contact the closest Phoenix dealer for this maintenance activity.

Unifarm Machinery Corporation
PO Box 38, Wilson, NC, U.S.A.
page 17
picture 11 picture 12
picture 13 picture 14
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.
BLADE REPLACEMENT
To assure the optimum efficiency of the machine, make sure that the tiller blades are in a good
working condition and that their bolts are tightened; replace them if they are broken or bent. The
new parts must be installed in the original position.
The T5, T10, T15, T20, T25, T30 tillers are equipped with 6 blades per flange; but it is possible to
reduce the number to four blades per flange (except for T25, T30 tillers), in case special ground
conditions require this modification.

Unifarm Machinery Corporation
PO Box 38, Wilson, NC, U.S.A.
page 18
Before replacing the blades, turn the tractor engine off, pull
the parking brake, disengage the power take off, raise the
tiller using the tractor lift, and install supports to prevent
accidental dropping of the machine.
Pay special attention to the bolts Aon the blades (picture 15): the screw head must be placed on
the blade side, with the washer and the nut on the flange side, so that the bolts cannot loosen while
the equipment is being used.
When several blades must be replaced, replace one blade at a time, so that the initial helical layout
is maintained (picture 16).
