10.3.5 Inspection of knives and securing
elements

with genuine KUHN parts.
When the following equipment is fitted:
• Knife attachment per bolt and nut.
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.
The length C of a knife must exceed 65 mm (2.6’’).
- The width B of a knife, measured at A = 10 mm
(0.4’’) of the disk, must exceed 34 mm (1.34’’).
Elongation of hole due to wear:
- Check that there is still a minimum value L
equalling 9 mm (0.35’’).
- Always replace both knives per disc to avoid
creating an out-of-balance force.
