SAFETY
Most accidents occur during work, maintenance, or transport due to non-observance of the fundamental
safety requirements. This is why you are the most important person for operating and maintaining your
mower. Regardless of whether you are working alone, with your family members, or with other persons,
always read and observe the basic method of operation. Additionally, warning labels are affixed on the
mower that serve as a reminder to always observe safety practices.
- Read this manual carefully prior to beginning work.
- Metal nameplate must always be legible, visible and clean.
- Every time before using the mower check whether all parts (nuts, screws, etc.) are tightened,
and especially secure the rotor cutters, rotor ends to the supports, lower pins to the supports and the
pyramid to the mower body.
- If the cutters and their fasteners (nuts, bolts, etc.) are worn out or damaged,
replace them immediately with original parts from FPM AGROMEHANIKA AD BOLJEVAC.
- For reasons of safety, check if the protectors on the tractor connecting shaft and PTO shaft
of the rotary mower are correctly installed and secured.
- Use a PTO shaft recommended by the manufacturer.
- Fasten the PTO shaft guard with the provided chains. (PTO
shaft guard may not turn.) If the guard is damaged, replace it immediately.
- When the PTO shaft is not in use, place it onto its provided location on the machine.
- Prior to adjusting, lubricating, or cleaning the mower, turn off the tractor and switch off the
PTO shaft.
- Wait until all moving parts have come to a stop before approaching the mower.
- Keep away from all mower parts while working.
- Never wear clothing that can get caught in the mower’s moving parts, and when approaching the
moving mower, pay particular attention that the clothing is not caught by the rotor or the PTO shaft.
- Never transport an unsecured mower .
- Never transport an operating mower.
- Never transport others on the mower or the tractor during work or transport.
- Never turn on the connection shaft when the mower is in the transport position.
- The operator must ensure that no individuals or animals are in the work area of the

GENERAL INFORMATION
Rotary mowers for soil cultivation with active cutting tools — tines are a range of rotary machines
for cultivation with horizontal axis of rotation driven by the tractor output PTO shaft.
The transmission module provides optimal usage of the tractor power when coupled with a
connecting shaft, due to small transmission losses, while operating at standard connecting shaft rpm of
540 min
-1
; optimal work modes and other conditions regarding safety, overload control and protection
that may be expected during operation.
The work module, rotor with cutters, provides good cultivation quality under any operating
conditions and modes thanks to its shape, geometry and arrangement with minimum energy consumption,
human or mechanical work per unit of volume of cultivated soil.
The rotary mowers are suitable for all kinds of different agricultural production applications.
This machinery is best suited for:
-high-quality soil cultivation and preparing the soil for one-pass sowing
-small-scale placing and compacting of soil and protection from erosion
-all-year application for basic and additional soil cultivation, meadow and pasture
regeneration and aeration, and intertillage in orchards
-maintaining the structure and increasing the soil fertility
-mixing the plant trimmings and mineral fertilisers with the soil
-operation on both lowland and sloped terrains
Transmitting the engine power from the tractor connecting shaft over the transmission to the
mower rotor with cutters not only prevents the tractor wheels from slipping and sliding, but on the
contrary pushes the tractor forward.
The mower is attached to the category I and II tractors. The machine is raised in the transport and
lowered in the operating position by using the tractor’s hydraulic control lever.
The rotary mowers are attachable to any domestically or internationally produced tractors with
adequate engine power at 540 min-1 tractor output shaft rpm.

OPERATING THE ROTARY MOWER
BEFORE USE
1. Check whether all parts (nuts, screws, etc.) are properly tightened, and secure the rotor cutters,
rotor ends to the brackets, lower pins to the brackets and pyramid to the mower body.
- If the cutters and their fasteners (nuts, bolts, etc.) are worn out or damaged,
replace them immediately with original parts from FPM AGROMEHANIKA AD BOLJEVAC.
2. When operating the mower, always use stabiliser links (Fig. 2) and stabiliser chains (Fig. 3). To
attach the stabiliser links to the tractor, proceed as follows (see Fig. 2).
a) Attach the left stabiliser link bracket (Fig. 2, pos. 1) under the housing of the rear left
tractor half-axis, and right under the housing of the rear right tractor half-axis (Fig. 2, pos.
2) by screwing it in.
NOTE: Position the stabiliser link brackets so that the pins for attaching the stabiliser rods are
facing each other, i.e. the tractor centre line.
b) Place the stabiliser links onto the bracket pins so that the slightly bent link ends are facing
the tractor centre line.
c) Secure the stabiliser links with safety keys.
3. If your tractor is equipped with stabiliser chains, follow the assembly method shown in Fig. 3;
assembly sequence matches the sequence for stabiliser link (see under 2)
4. Grease all required places on the rotary mower.

Attaching the rotary mower to the tractor
DANGER: Attaching the mower to the
tractor can be extremely
hazardous. Exercise great caution
and observe the instructions.
DANGER: Use a tractor
configuration that
meets the rotary
mower requirements.
Always perform the attaching operation on an even surface as follows:
1. First, remove the paint from the mower trunnions.
2. Reverse the tractor slowly to position it perpendicular to the rotary mower, lower the lower
linkages using the hydraulic controls until they reach the height of the centre line of the mower
attachment points, and turn the tractor engine off.
IMPORTANT: If the tractor is poorly positioned, it is much easier to move the tractor forward or
backward than trying to drag the rotary mower towards the tractor linkages by using your own
strength.
3. Attach the upper linkage to the top point support on the mower frame (Fig. 4, pos. A).
Figure 4. Attaching the mower. Figure 5. Proper position of the rotary
mower after attaching it to the tractor.
Figure 6. Checking the PTO shaft function

position.
Figure 7. Maximum refraction angle of the
PTO shaft.
4. Attach the left lower linkage (and the stabiliser link, if used) to the left rotary mower trunnion, and
secure it in this position with the provided keys (Fig. 4, pos. B).
5. Attach the right lower linkage (and the stabiliser link, if used) to the right rotary mower trunnion,
and secure it in this position with the provided keys (Fig. 4, pos. C).
6. Attach the front end of the PTO shaft (the end with the friction clutch) to the connecting shaft of
the mower and secure it in this position (Fig. 4, pos. D).
Page 17

Attach the other end of the PTO shaft to the connecting shaft of the tractor and secure it in this position.
ATTENTION: The PTO shaft guard must be affixed. Attach it before connecting the
PTO shaft with the tractor connecting shaft.
7. From the tractor seat, using the hydraulic controls in the lower quadrant position, move the tractor
slowly forward or backward until the front end of the upper linkage can be attached and secure it
in this position with the provided splines.
8. After attaching the machine to the tractor as described above, bring the centre line of the reduction
gear in the horizontal position by extending or shortening the upper linkage as shown in Fig. 4.
IMPORTANT:
Always observe the order of sequence when attaching the machine to the tractor:
a) left lower linkage
b) right lower linkage
c) upper linkage
9. If necessary, you can extend the tractor lifting links to the required length, ensuring that the
machine is not raised too far from the ground when the linkages are in the bottommost position.
This prevents any possible damage to the drive mechanism.
IMPORTANT:
After bringing the mower in the vertical position, you can proceed with other
adjustments required for normal operation of the rotary mower.
10. Using the hydraulic controls, raise the mower carefully so that the PTO shaft’s angle of refraction
is not too large. After raising the machine in the uppermost position by following this procedure,
check the following:
a) Check the PTO shaft for ease of movement and that the joins are not jammed.
b) Check that the PTO shaft is not extended too far.
c) Check the PTO shaft guard for ease of movement.
d) Attach the PTO shaft guard using the provided chains.
Repeat the procedure when the tractor is positioned so that the machine is hanging in the
bottommost position. To achieve this, drive the tractor with the attached mower up the ramp until
the machine is hanging in the bottommost position, ensuring that its lowest point is now
significantly lower than the tractor’s lowest point, as shown in Fig. 6.
Page 18

WARNING: If the PTO shaft is operating improperly in the bottommost position of the machine, shorten
the tractor lifting links.
ATTENTION: The maximum angle of
refraction of the PTO shaft is 30
degrees (see Fig. 27). If this angle is
exceeded during operation, serious
damage to the PTO shaft or connecting
shaft may occur. Take special care to
ensure that the universal joints are not
stuck.
NOTICE: Failure to observe the
fundamental requirements for the PTO
shaft operation may lead to breakage of
the PTO shaft or damage to the rotary
mower.
11. Adjust the lower linkages (and stabiliser links, if used) in order to limit the lateral swing of the
machine to 5 to 10 cm.
When working on sloped terrain, this swinging motion must be avoided; therefore, use stabiliser
links, or secure the tractor linkages with tension chains.
12. Mark all of the mower positions on the tractor for the purpose of avoiding these adjustments next
time, while ensuring proper mower operation.
13. If attaching the linkages to the mower is impossible,
reverse the attachment points order (see Fig. 7a), so
that both trunnions are facing inside. Other adjustment steps
remain unchanged.
All tractor-mounted rotary mowers manufactured by IMT Agromehanika AD Boljevac are designed
for attaching to the tractors with a three-point linkage, irrespective of the tractor category (I or II).
ATTENTION: When attaching the machine to the tractor, strictly observe the
instructions in this manual.
CAUTION: The rotary mower is attached properly if the following conditions are met:
1. When the centre line of the reduction gear casing is brought in the horizontal position with
rotor cutters nearly touching the ground.
2. When the distance between the tractor and the mower is the shortest possible, PTO shaft
components may be extended so far that they are not telescoping completely.
When the mower is raised in the topmost, or lowered in the bottommost position, PTO
shaft components may not fall out from one another.
3. When the mower is raised in the topmost, or lowered in the bottommost position, joint
components are not touching each other.
4. When the mower is brought in the lateral vertical position (achieved by adjusting the lower
linkages, lifting links, and levelling lever).
Page 19

DETACHING THE MACHINE FROM THE TRACTOR
1. Slowly lower the rotary mower to the ground.
2. Sitting in the driver’s seat, decouple the upper linkage end (Fig. 4, pos. A) from the tractor while
moving slowly forward or backward with the tractor, if necessary, for easy removal of the pin.
-Replace the pin on the tractor and secure it with the lock.
3. Remove the front PTO shaft joint from the tractor connecting shaft (Fig. 4, pos. E).
4. Detach the right lower linkage using, if necessary, the levelling lever on the tractor in order to
make the entire detaching process easier (Fig. 4, pos. D).
5. Detach the left lower linkage (Fig. 4, pos. B).
WARNING: After decoupling the machine from the tractor linkages, replace the locks on the links to
prevent them from being torn off when the tractor is moving.
ADJUSTMENT AND MAINTENANCE
CAUTION: Remove all objects when
adjusting your rotary mower. Foreign
objects and parts may be ejected in the
direction of individual standing by.
ATTENTION: Prior to performing
any adjustments or configurations to
the machine, switch off both the PTO
shaft and the tractor engine.
If handled and maintained properly, rotary mowers manufactured by FPM Agromehanika d.o.o Boljevac
ensure better quality of work and have a longer service life. Therefore, always follow the instructions
given in this manual, in order to achieve optimal performance and quality.
Any worn or damaged parts must be replaced with original parts from FPM Agromehanika AD Boljevac
to ensure high quality and precise assembly.
