•
Uneven wear of the pair of blades, which
could cause unbalance
Check the blade holder, blade bolts and mowing

matched to the forces to be expected.
Parts to be checked:
Blade bolt (30)

Immediately after hitting an obstacle
Immediately in case of abrasive noises in the area
of the cutter bar
Control criteria:
• Uneven wear of mowing blades (32) (danger of
unbalance)
• Bent or damaged mowing blades (32)
• Bent, damaged or worn blade holder (the wear
area of the blade holder has reached the edge of
the hole) (31)

1. Insert lever (H) at a right angle to the ground (Pos A)
between mower disc and blade holder.
2. Turn the lever (H) until it appears in line with the mower
disc (Pos B). This will push the blade holder (31)
downwards.
3. Remove the mowing blade (32).
4. Cleaning: Remove chuck residues and dirt from the
blade bolt (30) and on the inside of the hole on the
blade holder (31).
5. Check wear parts for the control criteria listed above.
6. Insert mower blade:
a. If you have to change the mower blade (32), always
change both blades of the respective mower disc.
b. When inserting a mowing blade (32), pay attention
to the running direction of the mowing disc. The
mowing blades are labeled accordingly. Insert a
mowing blade with the same direction of rotation
(R,L) as the old mowing blade.
7. Visual inspection of the assembly: Ensure that the
mowing blade (32) is placed between blade bolt (31)
and blade holder (30) as shown.
