2. INTRODUCTION
 This operator’s manual should be considered as the basic mower’s equipment and keep for
future use. 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.
GENERAL WARNING
When operating the mower please comply with the warnings and
safety regulations shown throughout this manual by this safety alert
symbol.
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
1. Double-end disk mower is equipped with Perfect Cut 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 cutting bar and its tilt angle
„Perfect Cut” cutting bar
No tilt 3° tilt 5° tilt

Optional heights when using high mowing double topping
 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
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.
 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.
Note: Grass, which is very rare should be mowed with zero angle inclination.

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 familiarized with its detailed specifications and with safety rules and
regulations. Willful changes of the mower will lead to revoking of the warranty.

4. SAFETY ADVICE
4.1. Safety rules and regulations
 During operation of the mower the Regulation of the Farm Ministry and Food Economy
(Rozporządzenie Ministra Rolnictwa i Gospodarki Żywnościowej) from 12-01-1998 dealing
with safety and hygiene during the operation of tractors, machinery, tools andequipment used
for farming (Dz. U. Nr 12/98 poz. 51), should be observed.
 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.
 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 working to transport position unmount the whole or at least one end (from
tractor’s PTO) of PTO shaft.
 When mounting the mower on a tractor, danger of wounding is present. It is recommended for
the operator to wear protective gloves.
a) Operation without safety guards as well as with damaged or raised guards is not allowed
(danger of stones, etc. being thrown out). Damaged protective apron should be replaced with a
new one
 Start mowing only when tractor’s PTO reaches its normal 1000 rpm.
 DO NOT exceed 1050 PTO rpm.
 Nobody is allowed to remain within 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
