dealer for more detailed information on the machine.
2. INTRODUCTION
❑This operator’s manual is essential for safe and proper use of this mower and should be read before
anyone operates this mower. It should be kept near the mower for future use. If the mower is used
by other operator, it should be in working condition and include this operator’s manual and all other
basic equipment.
❑Operator’s manual is delivered with every machine so that the operator can familiarize himself with
the design, working principle, servicing and adjustment of the mower. The operator should be
familiar with common safety rules and procedures.
❑The mower is manufactured according to international safety rules.
❑Compliance with the safety precautions in this operator’s manual will enable safe operation.
❑Please contact your dealer if you have any queries relating to the operation and service of
the mower.
❑This operator’s manual is an indispensable part of any machine and is intended to familiarize future
user with principles of proper operation and use of the machine as well as the risks involved.
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.

Note: Grass, which is very rare should be mowed with zero angle inclination.
❑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.

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.

KDT
REAR DISC MOWER
OPERATOR’S MANUAL
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.
❑No person and no objects must remain on the mower when driving or transporting.

KDT
❑When taking turns pay particular attention and consider the machine's weight and dimensions.
4.2. Qualifications of operator
To provide safe machine operation each person being the machine operator must meet the following
requirements:
❑Operator should hold driving license, have ability to drive vehicles safely and know road traffic rules.
❑Operator must be in proper physical condition to be able to operate the machine.
❑Operator must not be under the influence of alcohol, drugs and medicines, which all have influence
on vehicle driving and machine operation.
❑Operator should be familiarized with this manual and follow its provisions.
❑Operator should be familiar with working principles of both the tractor and the machine, and be able
to recognize and avoid hazards resulting from operation of the aggregate.
4.3. 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.
4.4. 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
