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 pr esence of the shar p edges of the cutting system and the possi-
bilities 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 wor king 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 fr om the tr ansport position to the operating posi-
tion 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 instruc-
tions 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.

GENERAL INFORMATION
Sales Information
The technical condition and the equipment of the mower should be checked at the time of purchase.
It should be required from the equipment dealer to carefully fill out the Warranty Registration Form. Failure to pro-
vide the date of purchase or the dealer’s information might cause the buyer to suffer disapproval of any possible com-
plaints.
Equipment and Spare Parts
The mower includes the following basic equipment:
 The Operator’s Manual, Parts Breakdown and Warranty Registration Form 1pc.
 Blade Changing Tool 1pc.
 Blades (packed) 18pcs
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 piv-
otally 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 operat-
ing 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 pos-
sible 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 slip one way clutch allows for free movement of the drums after disengaging the engine and protects the drive
elements from any damage.

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 ad-
ditional cover on the side of the tractor’s power take-off and the machine’s power input creates immediate
hazard of an accident.
