The blades differ, are at 90° to one another, and are con-
tra-rotating. When installing them, make sure that they are correctly posi-
tioned by refering to the code number marked on the outside of each one.
When re-fitting the blades, always follow
the indicated sequence, making
sure that the blades' wings are
facing towards the interior of the
cutting deck and that the cupped
side of the cup washer (1) is pres-
sing against the blade. Fully tigh-
ten the fixing screws (2), prefera-
bly using a torque wrench set at
45-50 Nm. If the shaft hub (3)
came off when dismantling the
blade, make sure that the key (4)
is firmly in its correct position.
