Knives
- Inspect systematically all knives before the machine is
operated to:
• Ensure the cutting quality.
• Ensure 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 80 mm (3.15’’).
Knife width B, measured at a distance A of 10 mm (0.4’’)
from the disc edge must exceed 20 mm (0.8’’).
The hole L for the securing bolt must not become oval by
more than 20 mm (0.8’’).
- Always replace both knives per disc to avoid creating
an out-of-balance force.
Immediately replace worn or damaged parts with
genuine KUHN parts.
