3. PROPER AND INTENDED USE
Mower KDT is equipped with the Perfect Cut cutterbar. The mowing height differences,
depending on the inclination angle of the cutterbar are shown below Tab. 1.

•The front mounted disc mower is intended for mowing green fodder such as grass and alfalfa
on permanent grassland (pastures), on crop fields without rocks, and forming 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.
•The front mounted disc mower with tine/roller conditioner is intended for mowing green fodder
such as grass and alfalfa on permanent grassland (pastures), on crop fields without rocks, and
forming 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, 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 grass it
should be cut at a height of 2". The last cut 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

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
shoes, safety gloves plus ear protection and dust 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
 DO NOT exceed 600 PTO rpm.

 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, and
 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
knives and knife 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 bot 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.
 During transport, always put the mower in its proper and safe transport position. See section 5.3.
 Before putting the mower in transport position, make sure that the tractor’s PTO is turned off
and all rotating parts have come to a complete stop.
 Do not drive over 25 km/h (15 mph). Drive slower if road conditions are poor, especially on
irregular surfaces or steep slopes.
 The behavior of the tractor on the road, such as its turning and braking capacities, are affected
by the implements mounted.
 When driving on the road after work, check to make sure that the tires and soil working tools
are clean to prevent the road surface from becoming dirty.
 Make sure that the machine is not damaged during transport.

After the mower has been attached to tractor, check the balance and steerability of tractor-mower
set. To do this, calculate to formulas given in the appendix or weigh the set, and then drive on the
scales only with 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, the front axis should be balanced.
