Maintenance and service
6.7.1.
Checking the knives and knife holders
All knives should have the same lengths and weights. Always check mower before starting
work for damaged, missing and/or worn knives. Replace them, if necessary, only in sets. Make sure
all knives in a set are of the same length and weight.
If the knife holder pin is worn too much and/or the knife holder is worn or deformed, please
replace it immediately (Fig. 27).
Fig. 27. Permissible wear of knife holder pin
CAUTION:
If the knife is missing or disc cover plate is damaged the vibrations may
occur, which leads to cutterbar’s damage. In that case warranty claim will be
revoked. If the disc or disc cover plate is damaged, the whole set must be
immediately replaced (2 knives) with new genuine ones.
