2. INTRODUCTION
 This instruction should be regarded as part of the basic equipment of the mower and keep for
future use. When the mower is turned over to a different user it should be in working condition
and accompanied by this instruction manual and all other basic equipment it should posses.
 Before operating this mower the user should first completely read the instructions in this
manual and should be familiar with general safety rules.
 The mower has been manufactured in accordance with all safety norms.
 Adhering to the instruction manual guarantees the user full safety during operation.
 In the event of any doubts regarding starting and operation of the mower please contact
the manufacturer.
 The instruction manual is an integral part of the equipment of the mower.
GENERAL WARNING

3. INTENDED USE
1. A mower without crop scarifier or rollers is equipped with the „Perfect Cut” cutterbar
or optionally with the „Heavy Duty” cutterbar. In table 1 the mowing height differences,
depending on the tilt angle of the cutterbar are shown.
Tab. 1. Mowing height depending on the kind of the cutterbar and its tilt angle
„Perfect Cut” cutterbar
No tilt 3° tilt 5° tilt
„Heavy Duty” cutterbar
No tilt 3° tilt 5° tilt
 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” cutterbar or
the optional „Heavy Duty” cutterbar.
 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.

WARNING:
It is forbidden to use the mower for purposes other than those listed in this
instruction. Using the mower for other purposes will be classified as use not
according with the intended use and could exclude the manufacturer from
responsibility from any resulting damages. The mower should be used, serviced and
repaired only by persons familiar with its characteristics and with safety
regulations. Unauthorized modification of the mower may release the manufacturer
from responsibility for any resulting malfunctions or damages.
3.1. Technical data
1. The KT mowers can be generally divided into two groups:
 mowers with hydro - pneumatic suspension
 mowers with spring suspensions
2. The hydro – pneumatic suspension replaces the traditional springs which significantly improves
the comfort of mower operation. Thanks to this solution the operator can, using the hydraulic
system of the tractor quickly set the pressure of the cutterbar on the ground. Additionally this
system is integrated with the hydraulic safety device.
3. Emitted noise: up to 105 dB. Noise measured by noise meter from 1 m distance from
the machine in motion in final test area.
4. The technical specifications of the groups mentioned above are presented below.
