6.10.1. Checking the blades and blade holders
All blades should have the same lengths and weights. Always check mower before starting
work for damaged, missing and/or worn blades. Replace them, if necessary, only in pairs.
If the blade holder pin is worn too much (Fig. 34) and/or the blade holder is worn or
deformed, replace it immediately
Fig. 34. Permissible wear of blade holder pin
NOTICE:
If the blade is missing or disc cover plate is damaged the vibrations may occur, which can
cause cutterbar damage. In that case, warranty claim will be rejected. If the disc or disc
cover plate is damaged, the whole set must be immediately replaced (2 blades) with new
genuine ones.
6.10.2. Checking the tension of tine and roller conditioners’ driving chain
Drive from conditioner and rollers driving shaft is transmitted by chain onto conditioner’s or
rollers’ axis. Constant chain tension is provided by tensioner, adjusted with tensioning bolt N (Fig.
35).
Properly tensioned chain, after being pressed with finger on tensioner end (K) should deflect
by approx. 2".
