Replacing The Knives And Knife Mountings - SaMASZ KDD 861 Operator's Manual

6.4.

Replacing the knives and knife mountings

Worn and/or damaged knives should be immediately replaced (Fig. 31). Replace knives, if
necessary, only in sets. When replacing, carefully inspect a knife mounting. If knife mounting
(Fig. 30) is worn, immediately replace two mountings (tightening torque 130 Nm / 96 ft-lb (Fig.
32)).
NOTICE:
When operating pay attention whether there are no excessive vibrations of the
mower which may indicate that the disc(s) operate with 1 cutting knife
attached only. Long-term cutting with insufficient amount of knives will cause
permanent damage to the cutterbar, not eligible for a repair under the
warranty. When operating check knives for completeness.
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.
WARNING!
Due to various windrow widths in the mowers (and therefore various rotation
directions of the discs), before mounting the knives check rotation directions
of each disc (Fig. 33).
