6.3. REPLACEMENT OF MIXER BLADES
Visually inspect the blades (for chipping, bends and cracks) from the
service platform. Sharpen blunt blades on your own; immediately
replace all damaged blades (worn-out blades are not covered by the
warranty). Periodically enter the feeder wagon tank to inspect the
tightening of the blade fastening nuts on the mixer. Tighten (and loosen)
the nuts with a box wrench (size 30); counter the bolt with Allen key size
12. Tighten the nuts to 425 Nm. If the cutting performance is reduced
or the feed cutting time is significantly longer, the blades are blunt and
must be replaced. Two persons are necessary for blade replacement:
one person holds the blade while the other tightens/removes the bolts.
Use two ladders to enter the feeder wagon's tank. Insert the taller
ladder (with hooks located at 140 cm) into the eyes on the platform and
hook it on the tank rim. Rest the other ladder inside the tank and hook
in on the inner ring. Use the ladder end over the tank rim as a support
when moving between the ladders.
The new blades should be secured with plastic
covers that are removed once all blades have been
secured on the mixer
Carry the blades in metal buckets.

Before entering the feeder wagon's tank to inspect
and retighten the nuts or to replace the blades:
•
park the machine on a level and solid ground away
from overhead power lines;
•
turn off the tractor engine, remove the ignition
key, and engage the parking brake on the tractor
and the machine;
•
decouple the telescopic jointed shaft from the
tractor and from the feeder trailer;
•
turn the PIC by hand to move the mixer in order to
expose the tank bottom part on which the ladder
will stand;
•
set up the ladders as explained above.
wARNING!
Exercise extreme caution when replacing the blades
(and retightening the nuts) – there is a risk of cutting
or crushing the handling person's body between the
blade/mixer and the tank wall.

Use the following equipment to replace the blades
(and retighten the nuts):
•
robust (leather) work gloves;
