2. INTRODUCTION
 This operator’s manual should be considered as the basic mower’s equipment. If the mower is
handed over to another operator, it should be in working condition and given away along with
operator’s manual and it’s other basic equipment.
 Operator’s manual is attached to every machine in order that the operator can familiarize
himself with design, working principles, service and adjustment of the mower. The user of the
mower should be familiar with common safety rules and procedures.
 The mower is manufactured according to international safety rules.
 Compliance with the warnings in this operator’s manual will ensure safe operation.
 Please contact your dealer if you have any queries relating to the operation and service of
the mower.
 Operator’s manual remains part of mower’s equipment.
GENERAL WARNING
When operating the mower please comply with the warnings and
safety regulations shown throughout this manual by this safety
alert symbol.
CAUTION:
Operation of the mower before reading the operator’s manual carefully
as well as operating by the unauthorized staff, especially by children, is
strictly forbidden.

3. PROPER USE
1. A mower without crop scarifier or rollers is equipped with the „Perfect Cut” cutting bar
or optionally with the „Heavy Duty” cutting bar. In table 1 the mowing height differences,
depending on the tilt angle of the cutting bar are shown.
Table 1. Mowing height depending on the kind of the cutting bar and its tilt angle
„Perfect Cut”

 The rear mounted disc mower is intended to mow green fodder: grass, alfalfa and such 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, best if prepared by rolling. In
the event of a majority of tall grass the first and second mowing should be done at a height of
60 - 70 mm, while with a majority of short grasses at a height of 50 mm. The last mowing
should be done a little higher - at 70 - 80 mm from the ground.
2. A mower with the crop scarifier/rollers is equipped with the „Perfect Cut” cutting bar or the
optional „Heavy Duty” cutting bar.
 The rear mounted disc mower with crop scarifier/rollers is intended to mow green fodder:
grass, alfalfa and such on permanent grassland (pastures), on crop fields without rocks, and to
form loose rows of cut fodder. 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, best if prepared by rolling. This is especially true of mowers with rollers
as they tolerate rocks with a diameter of a few centimeters. If a larger stone is picked up stop
and remove it as it could cause damage of the discs. With a majority of tall grasses the first and
second mowing should be done at a height of 6 - 7 cm, while with a majority of short grasses at
a height of 5 cm. The last mowing should be done a little higher - at 7 - 8 cm from the ground.

as improper and may lead to revoking of the warranty. Mower should
be used, operated and repaired only by people familiarized with its
detailed specifications and with safety rules and regulations. Willful
changes of the mower will lead to revoking of the warranty.

4.7. Design and operation of safety breakaway device
Hydraulic safety breakaway design protects mower against hitting small obstacles. In
the event of hitting an immovable obstacle the cutterbar folds back about 30 degrees and at the
same time rises about 70 cm. After that, the cutterbar automatically comes back to working
position.

Fig. 10. Simultaneous holding back of the mower up and backwards when safety breakaway advice is used
CAUTION:
Proper operation of hydraulic safety breakaway device is ensured only
by manufactured adjustment of the valve (500 kg). Changing of safety
breakaway device adjustment will lead to losing of warranty.
5. OPERATION
5.1. Attaching the mower to the tractor
Mower’s frame is adjusted to be attached to the tractors class 2,0 and 3,0. The mower is
connected to tractor’s 3-point-linkage (Fig. 11). After the mower has been attached, adjust (on flat
ground) mower’s position by means of top Sand lower links W(Fig. 11). The cutterbar should lean
towards driving direction. Lower links W should be connected to 3-point linkage frame pins A.
Connect hydraulic hoses to tractor’s hydraulic connectors.
After the mower has been attached to tractor, check balance and steerability of tractor-mower
set. To do it, weigh the set and after that drive on the weigher with only front axis of the tractor
(the mower must be in transport position – lifted upwards). If the pressure on the front axis is at
least 20% of the whole set’s pressure, it means the set is stable. If not, front axis should be
balanced.
