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.

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
a) mower without conditioner
SaMASZ rear disc mower is designed for mowing standing grass on meadows and in stone free fields.
It is a machine for hay and green fodder production. When the high grass prevails, the first and the
second cut should be mowed at the height level - 6-7 cm, but when the grass grows low – at the height
level - 5 cm. The last cut should be mowed a little bit higher – 7-8 cm above the ground.
b) mower with tine/roller conditioner
SaMASZ rear disc mower with tine/roller conditioner is designed for mowing standing grass on
meadows and in stone free fields. It particularly concerns mowers with roller conditioner, because they
tolerate stones only up to few centimeters. If a mower comes across a bigger stone, tractor-mower set
must be stopped and the stone removed, because it may lead to serious damage. It is a machine for hay
and green fodder production. Tine/roller conditioner provides effective conditioning and accelerates
drying of the forage. Roller conditioner is recommended in case of fragile crops like lucerne (alfalfa).
It reduces leaf loss to an absolute minimum. When the high grass prevails, the first and the second cut
should be mowed at the height level - 6-7 cm, but when the grass grows low – at the height level - 5
cm. The last cut should be mowed a little bit higher – 7-8 cm above the ground.
CAUTION:
Use of the mower for other purposes than the above mentioned
is forbidden. Different use than the above mentioned will be considered
as improper and may lead to revoking of the warranty. Mower should be
used, operated and repaired only by people familiarised with its detailed
specifications and with safety rules and regulations. Wilful changes of the
mower will lead to revoking of the warranty.

4. SAFETY ADVICE
4.1. Safety rules and regulations
 Front axis of the tractor should be weighted to keep the balance. If need be, use front wheel
weights.
 Any operation with the hydraulic lift lever should be done from the operator’s seat; DO NOT
move the lever from outside of the 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 working to transport position unmount the whole or at least one end (from
tractor’s PTO) of PTO shaft.
 Operation without safety guards as well as with the damaged or raised guards is not allowed
(danger of the stones, etc. being thrown out).
 Start mowing only when the tractor’s PTO reaches its normal 540 rpm.
 DO NOT exceed 600 PTO rpm.
 Nobody is allowed to remain within the danger area of at least 50 m. Particular caution is
necessary when operating near roads and in stoney areas.
 Any maintenance and adjustment work should only be done after the drive has been disconnected
and when the cutting discs have come to the complete standstill.
 Always check the mower before starting work, in particular for damaged, missing and/or worn
knives and knife holders. Damaged or worn parts must be replaced.
 When driving on public roads always comply with local traffic regulations, especially concerning
warning lights.
CAUTION:
All service and repair operations must be done only after the tractor
engine has been stopped, all rotating parts have come to the complete
standstill and the cutterbar is on the ground.
CAUTION:
Be certain that children and animals are at a safe distance away from the
machine. Never allow anyone to ride on a machine or tractor.
 When the mower is lifted for repair on the 3-point linkage, it should be secured against
falling by a 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 on and the cutting discs are rotating.
 When operating the mower, the tractor should always be equipped with the cabin.
 Mower should not be operated when the tractor-mower set is not balanced.
 Never start the mower when it is lifted.
 Never start the mower, when people or animals are near the machine.
 Never lift the safety guard before the rotating parts have come to the complete standstill. Tractor’s
engine must be stopped.
 Always comply with the safety decals describing hazards, and warning signs placed on the
machine.
 Before you start the tractor make sure that every other drives are turned off and the levers steering
hydraulics are in neutral position.
 Never leave the tractor’s engine running without supervision. Before you leave the tractor, turn off
the engine and put off the key from tractor’s ignition switch,
