3. PROPER AND INTENDED USE
Rear disc mower is equipped with the Perfect Cut cutterbar. Table 1 shows the mowing height
differences, depending on the tilt angle of the cutterbar.
Tab. 1. Mowing height depending on the kind of the cutterbar and its tilt angle

 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
2.4" - 2.8", while with a majority of short grasses at a height of 2". The last mowing should be
done a little higher - at 2.8" - 3.1" from the ground.
 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 inches. 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 2.4" - 2.8", while with a majority of short grasses
at a height of 2". The last mowing should be done a little higher - at 2.8" - 3.1" from the
ground.
NOTE: Grass, which has not grown much should be mowed with zero angle inclination .

WARNING:
Use of the mower for purposes other than described above is forbidden. Improper
use can be dangerous and may lead to voiding of the warranty. Mower should be
operated and repaired only by people familiar with its detailed specifications and
with all applicable safety rules and regulations and with the relative dangers.
Unauthorized modifications to the mower will lead to voiding the warranty.
3.1. Technical data
Generally, KT mowers can divided into two groups:
- mowers with hydro - pneumatic suspension
- mowers with spring suspensions
The hydro-pneumatic suspension replaces the traditional springs. This significantly improves
the comfort of mower operation. The operator thus can quickly set the pressure of the cutterbar on
the ground with use of the tractor’s hydraulics. Additionally the latter is integrated with the
hydraulic safety device.
Emitted noise: up to 105 dB. Noise measured by noise meter from 3' 3" distance from
the machine in motion in final test area.
The technical specifications for the above mentioned groups are presented below.

3.2. Design and working principle
The linkage frame (1) enables connecting the mower to the 3-point hitch of the tractor. The
power from the PTO of the tractor is transmitted by the drive shaft, the miter gear (3) to the drive
shaft (7), which through the miter gear (8) powers the cutterbar (4). On the cutterbar (4), there are
discs with two cutting blades each. Hydraulic lifting cylinder (2) fed from the tractor external
hydraulics is used to adjust the mower to working position. 3-point linkage frame, onto which
spring-suspended cutterbar (4) is set. The mower is also equipped with a rotational cylinder (10),
which has two functions. The first one is possibility to fold the mower backwards which, in many
cases, significantly simplifies the transportation, while the second is the factory-calibrated hydraulic
safety device (11). The swath guides (5) and safety cover (6) are also installed on the main frame.
Support foot (12) is mounted to 3-point linkage frame (1). Optional equipment: warning plate with
combined lights and reflectors (13).

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 moving from working 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.
 No person (except operator) should stand within danger area which is a minimum of 170'
from any operating part, especially when operating near roads and in areas with stones and
other debris. Be certain that children and animals are at a safe distance away from the
machine .
IMPORTANT: Maintenance and adjustment should ONLY be done after the following has
occurred:
 tractor’s engine has been stopped and ignition key has been taken out,
 all rotating parts have come to complete standstill (NOTE: cutting knives will
rotate for several minutes after engine is turned off),
 the cutterbar is on the ground .
 Never tamper with or remove safety devices on the machine or make them inoperable.
 Before starting work and periodically thereafter, replace any damaged, missing and/or worn
blades and bladee holders.
 When driving on public roads always comply with local traffic regulations, especially those
concerning warning lights.
 When the mower is lifted for repair on 3-point linkage, it should be secured against falling
by mechanical support or by chain.
 The bolts and other fasteners have to be periodically checked and, if necessary, tightened or
replaced. DO NOT work with damaged or worn fasteners.
 Never lift the mower on tractor linkage when the drive is operating and the cutting discs are
rotating.
 When operating the mower, the tractor should always be equipped with operator protection
that is required by laws and regulations.
 Never start the mower when the mower blades are off the ground.
 Before you start the tractor make sure that all drives are turned off and the levers that turn
the hydraulics are in neutral position.

 Never leave tractor’s engine running without supervision. Before you leave the tractor, turn
off the engine and remove the key from tractor’s ignition.
 DO NOT operate the mower when driving the tractor backwards.
 Permissible inclination of the mower on a slope when working and during transport is 8°.
Exceeding this incline can result in mower tipover.
 Never stand between tractor and mower unless tractor and mower are secured against
moving by the tractor’s brake.
 If any maintenance must be done under an elevated mower, it must be blocked or otherwise
secured against falling.
 When the parts of the mower need replacement, use only original spare parts as described in
the spare parts list. Pay particular attention to PTO shaft’s guards and mower’s and tractor’s
spline shaft guards.
 Hydraulic hoses are potentially very dangerous. Do the following to minimize any hazards:
 Hydraulic hoses should be periodically checked and if any damage to the hoses have
occurred or if they have been used more than 5 years, replace with new ones.
 Never use scotch tape to repair hydraulic hoses.
 When connecting hydraulic hoses to tractor’s hydraulic connectors, make sure that
the tractor’s or mower’s hydraulic system is not under pressure.
 The mower should be stored under a roof and in a way as to not be hazardous to both people
or animals.
 In the event of an accident involving this mower in a field or on a road, follow all applicable
first aid procedures and contact SaMASZ technical service.
 Mower should be kept clean, so as to avoid danger of fire.
4.2. Conditions of mounting mower on tractor
 Prior to the mounting operation, be sure that the tractor and mower hitches are compatible
and that the tractor's hitch load is adequate for the machine which is to be mounted or
attached.
 Prior to mounting the machine, examine the technical condition of the mower's hitch
assembly and tractor's 3-point linkage.
 Use only genuine cotter pins to mount the mower on a tractor.
4.3. Transport
The lifting, handling and transporting operations can be very dangerous unless they are
carried out with the utmost caution. Have all persons not involved in the actual work move
away from the area and limit the zone where the operations are to be carried out. Also make
sure that the area in which the operations take place is clear and that there is a sufficient escape
route, i.e. a free, safe zone to which the operators can quickly move if the load should fall.
The safety hooks and ropes used to lift the machine must be of an adequate carrying
capacity.
To minimize the risk of serious injury or death, do the following:
 When the machine is converted from the transport position to the work position and vice
versa, you could be pinched or crushed by some of its parts. Take extra care when carrying
out these maneuvers and have all persons keep well clear of the danger zone.
 Do not change position of the mower until there are no people or animals around (pay
particular attention to children).
 While transporting the mower, put a warning plate with combined lights and reflectors and
warning triangle on the mower.

 Transport should be done by qualified and specifically trained personnel,
 Grab the mower by any lifting devices only in places indicated by hook sign (Fig. 5),
Fig. 5. Transport holders
 For mower lifting, use only lifting devices with hoisting capacity larger than mower’s weight
shown in data plate. This also applies to ropes and chains used for lifting,
 Do not lift if transport belts, belt suspensions, ropes are damaged. Whenever damage to these
parts occurs, replace with new ones,
 When mounting slings, chains, handles etc., always set the machine's center of gravity
properly,
 To safely support the machine, use ropes of adequate length so that the angle between them is
no greater than 120°, and the angle between the strand and the vertical is no greater than 60°,
 Lift the machine with the utmost caution and move it slowly,
