Replacement of knives

7.4
Install supports underneath the cutter bar if it is lifted
from the ground, and you intend to carry out work to the
machine.
The mower knives come in 2 different versions for discs with
LH or RH rotation. The front of the cutting edge has to point
downward, viewed in the direction of rotation of the disc
(fig. 30).
The mower knives have two cutting edges. After one edge is
worn, the knife can be reversed so that the second edge can
be used.
• Knives should always be replaced in pairs in order to keep
the disc balanced.
• Replace worn or damaged nuts and knife bolts.
• Type "S":
- use new knife bolts together with a locking agent, or
apply Loctite 243 to the threaded part of the bolt;
- tighten the knife bolts with a torque of 50-60 Nm
(5-6 kgm).
• Type "N":
- use new, self-locking nuts and tighten them with a torque
of 50-60 Nm (5-6 kgm).
