5.5 Blades
5.5.1 Safety
To reduce the risk of accidental injury in the event
of a collision and to protect important parts in the
cutting deck, a force limiter is integrated as fol-
lows.
• Shear bolts between blades and blade bar.
• Torque limiting between gear wheels and blade
shaft.
• Possibility of positive drive belt slipping on the
plastic gear wheels.
5.5.2 Replacing blades
Wear protective gloves when changing
blade(s) to avoid cutting yourself.
Check that the blades are always sharp. This pro-
duces the best cutting results. The blades should be
replaced once a year.
Always check the blades after a collision. If the
blade system has been damaged, defective parts
should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
The blades are replaceable. When replac-
ing, both blades on the same blade bar must be re-
placed to avoid imbalance.
Attention!
Note the following when reassembling:
• The blades and blade bar must be installed as in
fig 18.
• The blades can be turned 1/3 of a turn in their
mountings. Select positions so that the blades
are offset 90° from each other. See "5.5.3" be-
low.
Tightening torque:
Screws (18:P) - 24 Nm
Shear bolts (18:Q) - 9.8 Nm
In the event of a collision, the shear bolts (18:Q)
can break and the blades bend back. If this has hap-
pened, install genuine shear bolts and tighten as
above.
5.5.3 Synchronising, blades
The deck has synchronised blades.
If one of the blades has struck a solid object (e.g. a
stone), the synchronisation may be altered. This
entails a risk of the blades colliding with each oth-
er.
Correctly synchronised blades must be offset 90°
from each other. See fig. 19.
Always check synchronisation after a collision.
ENGLISH
If the blades are not synchronised, one or more of
the following faults may have occurred in the cut-
ting deck:
• The positive drive belt has slipped on the gear
wheels.
• Torque limiting between gear wheels and blade
shaft has deployed. The arrows in fig. 20 must
be opposite each other for an intact deck. When
torque limiting has deployed, the arrows are not
opposite each other.
• The blade member is incorrectly installed on
the blade shaft. Can be installed in three differ-
ent positions. See 18:R.
In the event of incorrect synchronisation according
to the two first alternatives, contact an authorised
Stiga workshop for repair.
