6.1. Mounting and timing of cutting blades
The cutting blades should be mounted as shown in Fig. 21. The blades recommended by the
manufacturer have dimensions of 105x49x4 and comply with the PN-EN 795:2002 standard. Mount
the blades so that cutting edges are directed towards the ground, and a blade lifts the grass after
cutting.

WARNING:
- Use only blades recommended by manufacturer.
- Check condition of blades and holders before each operation. Worn or
damaged blades should be replaced immediately.
6.2. Blade replacement
Replace blades, if necessary, only in pairs. Make sure both blades in a pair are of the same
length and weight. The blade holders (Fig. 22) must not be damaged or deformed. If the blade
holder pin is worn too much, please replace it immediately (Fig. 34)

NOTICE:
During work, if mower begins to shake, it means that the disc (discs) are operating only with one
knife. In that case, using the mower in this condition for a long time could cause serious damage to
the cutterbar.
