FPM AGROMEHANIKA | 13
4. FITTING THE MOWER
4.1 Fitting onto a tractor
- For the mower to function properly and optimally, the edge of
the cutter bar must be at least 5 cm away from the external edge of
the wheel tract. Figures 32, 33, and 34 show examples of tting the
mower onto three dierent types of tractors – for tractors that have
a wheel gap of 1.32m, connect the tractor levers as shown (gure 32).
For a wheel gap of 1.5 m attach the tractor levers according to gure
33. For tractors with a wheel gap of 1.65 m place the tractor levers as
shown in gure 34.
NOTE: ADJUST THE MOWER SO THAT THE GAP A IS AROUND 5
CM. CHECK THAT THE TENSION CHAIN (C) ALLOWS THE CUTTER
BAR TO TAKE THE APPROPRIATE POSITION FOR OPERATION.
- Make sure to properly tie the awning to the frame while assem-
bling! The awning (D) is tied to a plastic washer (Q), over which a nut
(O) and screw (F) is tied (gure 20). This image shows how to place
the belt with holes (A) and the belt with a loop (B).
- Mount the carrier (J) at the end of the protective frame, fasten it
with two screws (R) (M10x30), two washers (T)(ø 10) and two self-lock-
ing nuts (O) (M10) (gure 17).
- Fasten the additional carrier (S) with a screw (V) (M10x50), and a
screw (R) (M10x45) to the protective frame (see gure 21 and 17).
- Figure 21A shows how to roll the awning into the transport posi-
tion. After rolling the awning, fasten its front and rear part using belts
(A and B) as shown in gure 19, and the mower is ready for transport.
DANGER! WHEN WORKING WITH THE MOWER, THE
PROTECTIVE CANVAS MUST ALWAYS BE PLACED ONTO
THE FRAME AND LOWERED INTO THE WORKING POSI-
TION.

14
Fitting is achieved in the following way:
.
1 – Move the tractor backwards, using
hydraulics bring down the lower tractor levers
to the height of the mower linkage point axis
and carry out the tting and
locking of levers as shown under
A in gure 35.
2 – Upper tractor lever – connect
the coupling (B) with the axle (C)
to the connector on the upper part
of the carrier frame, depending on the
category of tractor turn the thinner or
thicker part of the axle and secure it with
existing tighteners.
3 – Connect the hydraulic tube connector to the appropriate
hydraulic connector on the tractor (one way)
4 – Following that action, using hydraulics
raise the mower o the ground to the
required height for transport.
5 – For safe transport of the mower,
pull out the tightener (A) (gure 36) and
lock the parking switch (B) into the groove (C)
and the mower is ready for transport.
4.2 Cardan joint
It is very important for the Cardan joint to be properly set while con-
necting it to a tractor. Cardan cranks must never be allowed to get
stuck together when the machine is raised into the highest or low-
ered into the lowest position. The Cardan joint has a safety link. Make
sure to place the safety link towards the mower, so that the cutter
can be turned on.
If you determine that the Cardan joint is too long and cannot be con-
nected to the tractor, it is necessary to shorten it. The following im-
ages illustrate the procedure for shortening the Cardan joint.
1 – Join rst one, then the other half of the Cardan joint onto the
tractor and the machine, keep one half next to the other, and by
various adjustments of the tractor and the machine, adjust the
length of 10 mm and label it on the protector, (gure 25).
2 – Cut o the protective plastic, see gure 26.
3 – Cut o the prole tube, see gure 27. Further modications to
the plastic and tube are not permitted.
CAUTION! THE FOLLOWING ACTIONS AND INSTRUCTIONS MUST BE RESPECTED IN ORDER TO AVOID DAMAGE TO
THE MACHINE AND CARDAN JOINT OR PREMATURE WEARING OF THE CARDAN JOINT. NEVER ATTACH THE CARDAN
JOINT TO THE TRACTOR OUTPUT SHAFT WITH 750 OR 1000 RPM.

FPM AGROMEHANIKA | 15
4 – Lower the sharp outer edges (gure 28).
5 – Clean and oil (gure 29). Connect the Cardan joint tubes with
one another.
6 – The Cardan joint protection must never be removed, nor
moved during operation.
Attach the protection carrier chain onto the machine shaft pro-
tection (gure 30).
7 – The Cardan joint must never operate under too big an angle
(10° at most)° (gure 31).
4.3 Transporting the mower
Before transporting the mower on public roads and from one work-
ing area to another, do the following:
1. Turn o the tractor output shaft and wait for all moving parts
to come to a halt.
2. Raise the mower using hydraulics to the required height for
transport, press the peg (A) (gure 36A) and raise the parking
switch (B) so that the groove (C) reaches the height of the peg
(gure 36A).
3. Move the axle (A) (gure 37), on the oating lever into the bear-
ing for the transport position (see drawing of label B), secure it
with a tightener, whereby you prevent the lever from oating.
DANGER! IN ORDER TO ENSURE SAFE FUNCTIONING OF THE CARDAN JOINT, PLACE ALL SAFETY PROTECTIONS AT
THE APPROPRIATE PLACES AND SECURE THEM APPROPRIATELY. IF THE PROTECTIONS ARE DAMAGED OR WORN-
OUT, REPLACE THEM IMMEDIATELY.

4. Fold the front half of the protective canvas (A)
backwards (see the arrow) (gure 38), and
tie it with the appropriate belts.
5. Lift the cutter bar using the hydraulic cylinderinto the trans-
port – vertical position.
6. Move the lever (T) from the neutral position, i.e. connect it us-
ing the carrier frame and secure it using the tightener (L) (gure
39), and the mower is ready for transport.
5. USING THE MOWER
5.1. Before first use
Before starting the mower for the rst time, perform the following
checks:
No. Description All right (√)
1Product integrity
2Check that the V-belts are tightened
3Check that the pulley nuts are tightened
4Check that all screws are tightened
5Check the position of discs and cutting blades
6Check that the cutting discs are tightened
7Check the level of oil in the multiplier
8Check the level of oil in the cutter bar
9Check that all grease ttings are oiled
5.2 Working with the mower
Once you have lowered the cutter bar from the transport into the work-
ing position, turn on the input shaft and let the cutter bar revolve for
some time at a low number of revolutions in order for the oil to spread
throughout the cutter bar casing.
Before you start mowing, increase the number of shaft revolutions to
540 min-1.
It is very important that the mower operates at a prescribed number of
output shaft revolutions, otherwise the results of mowing will be unsat-
isfactory, and at certain times congestions may occur.
The speed of motion should be adapted to ground conditions.
The mowing itself can be performed continually, i.e. without breaks
and raising the mower o the ground while turning, because there is
no congestion when the mower reaches a mowed mass, and due to the
specic shape of the cutting discs the already mowed mass will not be
ground.
Take measures of extreme caution when working on uneven ground.
Adjust the mower in such a way that the possibility of the blades hit-
ting foreign objects or the ground is minimal.
1. Tilt the cutter bar at an angle using the handle on the coupling
(B) (gure 43) which adjusts the cutting height.
3. Check that the cutting blades rotate when the cutter edge hits
an obstacle.
4. Sharpen the blades (using the appropriate tools).
The protective canvas (awning) holds back foreign objects that get
deected o the blades and cutting discs, and protects the user and
other persons present.
WARNING! THE FOLLOWING ACTIONS AND IN-
STRUCTIONS MUST BE RESPECTED IN ORDER TO
AVOID DAMAGE TO THE MACHINE AND CARDAN
JOINT OR PREMATURE WEARING OF THE CARDAN
JOINT. NEVER ATTACH THE CARDAN JOINT TO THE
TRACTOR OUTPUT SHAFT WITH 750 OR 1000 RPM.
WARNING! BEFORE STARTING WITH WORK, RE-
MOVE STONES, FOREIGN OBJECTS, AND HIDDEN
OBSTACLES FROM THE WORKING AREA.
DANGER! WHEN WORKING WITH THE MOWER, THE
PROTECTIVE CANVAS MUST ALWAYS BE PLACED ONTO
THE FRAME AND LOWERED INTO THE WORKING POSI-
TION.
DANGER! BEFORE STARTING WORK, MAKE SURE THAT OTHER
PERSONS OR ANIMALS AND NOT WITHIN THE MOWER’S WORK AREA.

5.2.1 Adjusting the cutter bar
1. Place the axle (A) (gure 40) into the working position. This re-
leases the spring and allows the cutter bar to properly handle
the ground.
NOTE: FOR SWITCHING THE AXLE INTO THE WORKING POSITION,
THE CUTTER BAR MUST BE RAISED IN THE TRANSPORT POSITION.
2. Remove the transport position level (T) from the mower frame
carrier and attach it onto the frame (awning carrier) and fasten it
with the existing elastic tightener (L) (gure 41).
3. Using the hydraulic cylinder, lower the cutter bar into the
working position.
4. Adjust the mower using tractor levers so that the linkage point
centres (A) are at the height of 450 mm (gure 42).
5. Insert the chain (D) into the opening on the tension hook (A)
on the tractor as shown in gure 43. Completely lower the tractor
levers, which adjusts the height.
The adjusting is good if:
- The cutter bar is leaning on the ground
- The chain is bound and tightened
- The distance between the linkage points and the ground is
around 400 mm.
Managing the hydraulic cylinder is of great importance for the prop-
er functioning of the mower.
The managing is carried out during work, which will facilitate your
work and increase working output.
WARNING! BE VERY CAREFUL WHEN LOWERING
THE CUTTER BAR! THERE MUST NOT BE ANYONE IN
THE WAY WHILE LOWERING THE MOWER’S CUTTER
BAR.

5.2.2 Adjusting the cutting height
The cutting height is adjusted by rotating the entire cutter bar around
the longitudinal axis. This is achieved by shortening or lengthening
the coupling length (B) (gures 43 and 44). This adjustment should
be carried out very carefully in order to achieve a proper cut while
mowing (gure 44).
5.2.3 Safety device
The safety device is by default properly set for working under nor-
mal working conditions, and is activated only when the cutter bar
encounters hidden (hard) obstacles in the ground. For mowers with
four discs, the spring (B) is set to the measurement (A) which equals
102 mm (gure 45).
For mowers with ve, six, seven, or eight discs, the safety system is
congured using plate springs to the length of 94 mm, shown as Y
on gure 46.
If there is a need to exceptionally modify the safety device for the
user in order to adapt it to local conditions, the main principle is that
the safety device spring must be adjusted in such a way as not to be
activated under normal working conditions.
NOTE: CHECK THAT THE SAFETY DEVICE CASING IS OILED. IF NOT,
OIL ALL SLIDING PARTS WITH TECHNICAL OIL.
If the cutter bar hits a hidden obstacle while in operation, the safety
device (R) is activated which detaches the cutter bar (gure 45).
Then take the tractor a little in reverse and lift the mower using the
tractor levers. Swing the cutter bar towards the tractor, which will
restore the safety system to the original, working position.
5.2 Swath-former
For proper setting of swath shape and mowed mass ow, it is neces-
sary to loosen or tighten the coil spring (A) (gure 53). In case of more
dicult working conditions, the swath-former angle must be greater
in relation to the cutter bar (as close to 90° as possible).
CAUTION! IT IS VERY IMPORTANT TO ADJUST
THE CUTTER BAR WHILE ADJUSTING THE CUTTING
HEIGHT SO THAT THE BLADES DO NOT HIT THE
GROUND DURING OPERATION. OTHERWISE, THE
BLADES WILL QUICKLY GET DAMAGED, AS WILL
THE ROOTS OF PLANTS. PAY SPECIAL ATTENTION
IF YOU ARE WORKING ON UNEVEN GROUND.
CAUTION! NEVER TIGHTEN THE SPRING TOO
MUCH IN ORDER FOR THE SAFETY DEVICE TO
WORK PROPERLY.
CAUTION! WHEN THE SAFETY DEVICE ACTI-
VATES, IMMEDIATELY STOP THE TRACTOR AND
TURN OFF THE OUTPUT SHAFT.

6. ADJUSTMENTS AND MAINTNANCE
For tightening the cutting discs, it is necessary to tighten the screw
(Q) (gure 51) with a torque of 18 daNm.
When mounting the cutting discs under the nut (Q), use a spring
washer (R) for properly fastening the discs. It is always necessary to
install a protective washer (P) beneath the bearing, which prevents
dust and dirt from entering the cutting disc casing (gure 51).
6.1.1 Controlling the blades and cutting
discs
A) BLADES: They should be checked minutely before starting with
mowing. Quality cutting and good, safe work depend on well-sharp-
ened blades.
1. DAMAGED BLADES
Very rough, rugged, and damaged blade edges lead to:
- increased risk of accident;
- lower quality cutting;
- risk of damage to the cutter bar.
2. WORN-OUT BLADES
The width (B) of a worn-out blade, measured from the distance of
10 mm from the cutting disc edge must not be less than 3/4 of the
normal blade width.
The length of the oval opening (L) on the cutting blade must not
exceed 18 mm.
6.1 Discs and cutting blades
The discs, cutting blades, and blade carriers are of a very quality
build. The blades and blade carriers are made of a special steel alloy,
which is hardy and resistant to wearing, and therefore gives them a
long working life.
NOTE: ONLY USE ORIGINAL PARTS AND THOSE RECOMMENDED BY
FPM AGROMEHANIKA.
After long use, the blades’ cutting edges start to get blunt, so that
the cutting quality will no longer be satisfactory. The blunted edges
of the cutting blades require increased power, while the stocks of the
mowed plants are uneven and rugged.
Before replacing the blades, clean the earth and dirt o the blade
carrier and nut, as shown under A in gure 50. Unscrew the nut and
remove the blade carrier from its bearing.
Two cutting blades are mounted onto each cutting disc, which
revolves clockwise, while the neighbouring disc revolves count-
er-clockwise.
When you have ascertained that the cutting blade edges have been
blunted, replace the blades on the neighbouring discs together,
since the blades have two edges.
It is possible to sharpen the cutting blade edges as long as the tem-
pered edge (thermally reinforced) remains, however it is necessary
to preserve the cutting edge angle. If the damage is great, the blade
must be replaced with a new one.
All discs should be adjusted in such a way that the blade axes take a
right angle (see gure 50).
For tightening the screw (A) (gure 50) which holds the cutting
blades, use a torque of 7.5 daNm.
DANGER! BEFORE MAKING ANY ADJUSTMENTS, RE-
PAIRS, OR MAINTENANCE OF THE MOWER, SWITCH OFF
THE CARDAN JOINT POWER, TURN OFF THE TRACTOR,
TAKE OUT THE KEY, AND WAIT FOR THE REVOLVING
PARTS TO COME TO A HALT.
WARNING! BEFORE DOING MAINTENANCE AND RE-
PAIRS TO THE MOWER REMOVE ALL FOREIGN OBJECTS
AND PARTS SINCE THEY CAN BE THROWN AT NEARBY
PERSONS.

B) CUTTING DISCS): They should be checked regularly! (Especially
check the screw tightening torque.) The tightening torque equals 7.5
daNm.
- Perform a check immediately after hitting a hidden obstacle.
- Perform a check when replacing the blades.
Always mount two blades of the same type onto a cutting disc, in
order to avoid unbalancing the disc.
Perform a check prior to every mowing season.
1. You must replace the blade carrier in the following cases:
- When there are visible deformities.
- When the head gets worn at the blade contact area.
- When the nominal circumference of the blade carrier
Dn = 16 mm reaches a maximum value on the worn blade
carrier of D = 13 mm.
2. You must replace the nut in the following cases:
- When the contact protective mass in the nut loses elasticity,
which is characterised by frequent loosening.
- When the wearing of the nut reaches a value of a = H/2.
6.2 V-belts
The V-belts must be properly tightened in order to prevent excessive
slipping. Insuciently tightened belts cause the cutter bar to oper-
ate badly and to damage and tear prematurely.
In order to tighten the belt, loosen the nuts (A) (gure 52). Tighten
the nut (B) until the force of 9 daN is achieved, i.e. the deection of 10
mm between the belts. While doing that, make sure that the casing
ts the frame properly. Finally, tighten the nuts (A).
NOTE: CHECK THAT THE BELTS ARE STILL TIGHT AFTER THE FIRST
1/2 HOUR OF USE. WHEN REPLACING THE WORN-OUT BELTS, RE-
PLACE THE ENTIRE SET OF BELTS, REGARDLESS OF THE CONDITION
OF ONE BELT COMPARED TO OTHERS
6.3. Oiling
It very important to properly oil the transmission components in
order to full the strict requirement for working even in the most
dicult conditions. It is best to release the oil immediately after n-
ishing with work, since the oil is still warm then, and the residue has
still not settled.
NOTE: THE LISTED TIMES FOR OILING ONLY REFER TO NORMAL
WORKING CONDITIONS. IF YOU ARE WORKING IN MORE DIFFICULT
CONDITIONS, MORE FREQUENT OILING IS NEEDED.
CAUTION! USE OIL OF THE REQUIRED QUALITY
IN ORDER TO AVOID DAMAGE TO THE MACHINE. BY
PROPER AND REGULAR OILING YOU WILL ENSURE UN-
IMPEDED AND SAFE OPERATION.
CAUTION! THE OIL IN THE TORQUE MULTIPLIER
AND CUTTER BAR MUST NECESSARILY BE CHANGED
AFTER THE FIRST 8 HOURS OF OPERATION. ONLY USE
SAE 80 W EP OIL.
