- Too low PTO rpm impair 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 is not always
possible. Adjust experimentally the inclination of the mower, PTO rpm, speed and correctness of
knife-mounting.
- In case of mowing soft meadows the pressure of the cutterbar on the ground should be reduced by
adjusting support springs.
5.7.2.Taking turns over swaths.
Lift the mower with hydraulic cylinder (Pos.2 Fig.3) and take the turn. The mower does not need to be
additionaly lifted by tractor’s 3-point linkage.

MOUNTING AND ADJUSTMENTS
6.1.
Mounting and timing of the knives
The knives should be mounted as shown in Fig. 14 and 15. The knives recommended by the
manufacturer have dimensions 115x49x4 and comply with the norm PN-EN 795:2002. Mount the
knives according to the rule, that the cutting edges should be directed towards ground, so that a knife
will lift the grass after cutting.
Fig. 14. Mounting of the knives on the mowing discs.
CAUTION:
Use only the knives recommended by the manufacturer.
6.2.
Replacing the knives
Worn and/or damaged knives should be immediately replaced.
Replace knives, if necessary, only in sets. Make sure all knives in a set are of the same length and
weight. The knife holders (Fig. 24) must not be damaged or deformed. If the knife holder pin is worn
too much, please replace it immediately.
CAUTION:
During work, please pay particular attention to mower’s shaking. If it
happens, it means that the disc (discs) works only with one knife. In that
case long-lasting mowing will cause serious damage of the cutterbar.
