Knives
Inspect systematically all knives before the machine is
operated to:
- guarantee the cutting quality.
- guarantee safety in use.
- Prevent cutterbar damage risks.
Replace knives in the following cases:
- Damaged knives.
• Very rough conditions can cause knives to crack
and become deformed.
- Worn knives.
Knife length C must exceed 65 mm (2.6’’).
Knife width B, measured at a distance A of 10 mm (0.4’’)
from the disc edge must exceed 20 mm (0.78’’).
The hole L for the securing bolt must not become oval by
more than 22 mm (0.86’’).
Always replace both knives per disc to avoid creating an
out-of-balance force.
