3. PROPER AND INTENDED USE
1. Mower is equipped with Perfect Cut cutterbar. The mowing height differences, depending on
the inclination angle of the cutterbar are shown in Tab. 1.
Tab. 1. Mowing heights depending on cutter bar’s inclination angle.
„Perfect Cut” cutting bar
No tilt
3° tilt
5° tilt
Standard mowing height
Optional heights when using high mowing topping
Optional heights when using high mowing double topping
 Rotational suspended disc mower is intended mow green fodder such as grass and alfalfa on
permanent grassland (pastures), on crop fields without rocks, and to form loose rows of cut
fodder. The pasture or field being mown should be even and best if prepared by rolling. In
the event there is a majority of tall grass, the first and second mowing should be done at a height
of 2.4" - 2.8", while with a majority of short grass, at a height of 2". The last mowing should be
done a little higher - at 2.8" - 3.1" from the ground.
 Trailed front mower with tine/roller conditioner is intended to mow green fodder such as grass
and alfalfa on permanent grassland (pastures), on crop fields without rocks, and to form loose
rows of cut forage. As a result of the passing of the layers of the green fodder through the flails
or rollers, the grass stems are broken and a layer of wax is removed. This facilitates and speeds
up the drying process of the fodder by approximately 30 to 40%. The use of rollers is especially
recommended when mowing legumes such as alfalfa. Rollers are particularly recommended for
mowing grass legume such as alfalfa.
 The pasture or field being mown should be even and best if prepared by rolling.
NOTE: Grass, which has not grown much should be mowed with zero angle inclination.

Fig. 2b. Design of the trailed disc mower with swath conditioner
Fig. 2c. Design of the trailed disc mower with swath rollers
Hitch (14) enables attachment of the mower to a tractor. Drive onto cutterbar (4) is
transmitted from the tractor's rpm through PTO shaft onto intersecting axis gear (19), drive shaft
located on tiller (13), wide-angle PTO shaft (6) onto intersecting axis gear (20), cutterbar drive shaft
(5) and intersecting axis gear (7). Cutterbar has discs mounted with two rotary knives each. Extreme
most discs have additionally mounted swath guiding drums. Moreover drive from tractor's rpm
through intersecting axis gear (20), drive shaft (10) and belt gear (9) is transmitted onto swath tine
conditioner (3a) or rollers (3b). Cutterbar is attached to linkage (1). Protective guard (16) is
mounted over the cutterbar. Maneuvering with the mower when driving is possible owing to two
hydraulic cylinders (12) which connect tiller to mower's linkage.

4. SAFETY PRECAUTIONS
The following precautions are for your safety. They must be read carefully
and followed by every person who operates or maintains the machine. Failure to follow these
safety precautions could result in serious injury or death to the operator, maintenance person or
bystanders and property damage to the machine and surrounding property.
Safety Signal Words
This manual and the safety labels attached to this equipment utilize signal words that signify
safety hazards with different levels of severity. Below are the words used and the definitions
for these words:
• DANGER indicates a hazardous situation which, if not avoided, will result in death
or serious injury.
• WARNING indicates a hazardous situation which, if not avoided, could result in
death or serious injury.
• CAUTION indicates a hazardous situation which, if not avoided, could result in
minor or moderate injury.
• NOTE is used to address practices not related to physical injury.
4.1. General safety rules and regulations
The following descriptions are for your safety: They must therefore be read carefully
and applied every time you use the machine.
 The machine has been designed for use by one single operator.
 When using, servicing, repairing, moving or storing the machine, the operator must wear safety
footwear, safety gloves plus ear protection and dusk mask if necessary.
 During use, the machine may give rise to dust, especially if the soil is dry. You are advised to
use a tractor with a cab fitted with filters in the ventilation system. Failing this, wear a dust
mask with filter to protect your respiratory tract
 Front axis of the tractor should be weighted to keep the balance. If need be, use front wheel
weights.
 In order to keep steering conditions, impact on front axis should be at least 20% of the complete
tractor.
 Be extremely careful whenever using hydraulic lift lever or buttons. Any operation with
hydraulic lift lever should be done from operator’s seat; DO NOT move the lever from outside
of a tractor.
 In case of tractors equipped with EHR, operating with hydraulic lift is done by the buttons
mounted outside the tractor’s cabin. When operating be extremely careful.
 When switching from mowing to transport position, remove the entire PTO shaft or at least one
end of the shaft from the tractor’s PTO so it cannot turn.
 When attaching the mower to a tractor, the operator should wear protective gloves.
 DO NOT operate the mower unless all safety guards are in place and operational. In addition,
any damaged protective aprons should be replaced with a new one
 Start mowing only when tractor’s PTO reaches its normal 1000 rpm. DO NOT exceed 1050
