direction, it significantly impairs the quality of mowing and in some cases the mower stops
mowing. Besides, it may lead to premature wear or even damage of the slides and cutterbar.
When high grass prevails, first and second cut should be mowed at height level 2.4" - 2.8",
but when the grass grows low it should be mowed at 2". The last cut should be mowed a
little bit higher, 2.8" - 3"
above the ground.
Too high a PTO rpm whirls the air, which may cause inclination of the grass in front of discs,
which impairs the quality of mowing.
Too low a PTO rpm impairs the quality of mowing and in some cases the mower stops mowing
(too low linear velocity of the knife).
In contrast with 2-drum mowers, straight mounting of the mower and full speed are not always
possible. Adjust inclination of the mower, PTO rpm, speed and correctness of knife-mounting to
get the best results.
In case of mowing soft meadows, the pressure of the cutterbar on the ground should be reduced
by adjusting support springs.
Always check to make sure that the ground speed suits the conditions or work and that it does
not create a potential source of danger
Do not take sharp turns anytime and do not operate in reverse.

Mower clogging
When operating the mower, pay attention to variable conditions on the field, which may cause
the mower to clog, such as: terrain unevenness, height and density of grass as well as other objects
in the grass. In order to avoid clogging, mowing speed should be adjusted to the conditions. In order
to take care of machine clogging, lower the cutterbar onto the ground, disconnect the drive and
remove the ignition key. When eliminating the mower's clogging wear all appropriate protective
gear.

Taking turns on headlands.
Lift the mower with hydraulic cylinder (Pos. 2 Fig. 3a, page 7) before turning. The mower
does not need to be additionally lifted by tractor’s 3-point linkage (Fig. 27).
