NOT APPLYING the rules mentioned above may cause hazard for the operator of the machine and bystanders,
as well as it may cause damage to the machine. For the damages resulting from the failure to
comply with these rules, the responsibility will be on the side of the mower’s user.
PARTIAL RISKS
The manufacturer has made every effort to ensure that the design and the intended method of operating the mower
does not cause any danger to people and their environment.
Due to the nature of the mower and the lack of such opportunities to fully expose the cutter, certain elements of risk
can occur.
THE DANGER caused by the presence of the sharp edges of the cutting system and the
possibilities of any hard objects thrown out, e.g. stones, broken blades, etc. The danger zone
resulting from the possibility of throwing out hard objects is within 150 ft. perimeter from the
mower being operated.
DANGER the working cylinders and the blades are still rotating for a certain amount of time even after the power
drive of the mower is turned off. Therefore, before proceeding with any work activities on the mower, it is crucial to
wait until the operating drums with the blades stop rotating.
DANGER changing the mower’s position from the transport position to the operating position and
backwards may be performed only on an even and flat surface after prior leveling of the machine.
Failure to comply with these conditions may cause the cutting system of the mower turn around on
its own on the suspension and hit or deform the operating elements of the tractor.
SAFETY SIGNS AND INSCRIPTIONS
There are warning labels placed on the mower with safety signs in the form of pictograms, which give clear
instructions and comments informing about what should be treated with special precaution in order for the operation
of the mower to be safe.
Carefully read every warning label and get familiarized with their meaning.
The warning labels should be kept clean and readable throughout the whole life of operating the mower. In case the
warning labels are not readable, the damaged labels should be replaced with new ones.
New systems and parts replaced during any repairs should have all required warning labels. The new labels may be
obtained from stores or from the manufacturer, as it is done with any other spare parts.

Design and Operation
The design of the mower:
1. Suspension
2. Central beam
3. Push rods, hydraulic cylinders (depending on the
version)
4. Main frame
5. Shield system
6. Stump jumper
7. Operating drums
8. Protective shield
9. Lock

7
The suspension system frame (1) is used to connect the mower with the tractor. The main frame (4) is connected
pivotally with the suspension frame through the central beam (2). The cutting system is made of two operating
drums (7) with blades attached rotationally in their lower part. The drums rest on the stump jumpers (8) when in the
operating position, which adjust to the ground contours.
Changing the position of the mower from the transport position to the operating position and backwards is made
possible through the pivotal connection of the of the suspension system frame with the central beam. The guards and
shield (8) protect the machine operator and other people from any hard object, which might be thrown out from
under by the operating drums (7).
The spring fuse prevents damages of the mower when the cutting system moves onto an obstacle; the operating
drums are powered by the tractor’s PTO. The drums along with the blades rotate in opposite directions cutting the
forage and forming it into windrows.
The one way slip clutch allows for free movement of the drums after disengaging the engine and protects the drive
elements from any damage.

then the right one) and secure them with cotter pins (Drawing # 4, point 3).
2. Slide the end of the upper connector between the yoke plates using the holes, then connect it with a bolt and se-
cure it with a cotter pin.
3. Lift the mower to relieve the support (Drawing # 4, point 5
4. Lift the support and support it with a cotter pin.
5. Tighten the chain (Drawing # 4, point 4) that’s limiting the side tilting of the tractor’s suspension system.
Assembly of the PTO Shaft
The drum mower should be equipped with an efficient PTO shaft with a guard, safety sign or the CE marking as well
as the technical specifications in accordance with the technical guidelines.
Using a PTO shaft with parameters different than those recommended by the manufacturer of the machine may over-
load the shaft, damage it or result in pulling both parts apart while lifting the machine and so create hazard for the
operators and the environment.
While assembling the PTO shaft, you should make sure, that the external pipe of the cover is on the side of the trac-
tor.
Tractor Mower
In order to install the shaft:
• Lower the mower down to the ground, turn off the engine and take out the key from the ignition.
• Insert the female tube end yoke to the power input of the machine and the power take-off of the
tractor and secure it from sliding out with rivets.
• Check whether the rivets secure the ends of the shaft from sliding out during operation.
• Install the chains of the shaft cover; one to the cover of the tractor’s power take-off, and the other to
the cover of the machine’s power input.
WARNING using a damaged PTO shaft, without the cover or a damaged cover, and without the
additional cover on the side of the tractor’s power take-off and the machine’s power input creates
immediate hazard of an accident.
