Replacing the knives
Replace knives, if necessary, only in sets. Make sure all knives in a set are of the same length
and weight. The knife holders (Fig. 30) must not be damaged or deformed. If the knife holder pin is
worn too much, please replace it immediately (Fig. 39).
NOTICE:
During work, if mower begins to shake, it means that the disc (discs) are
operating only with one knife. In that case
, using the mower in this condition
for a long time could cause serious damage to the cutterbar
.
WARNING:
When replacing knives, the engine must be stopped and the cutterbar must
lie on the ground. PTO shaft must be disconnected. Discs should be
perpendicular to cutterbar.
