Wear/Rotation/Replacing flail blades
After you have used your dethatcher for some time,
the blades will begin to wear on the striking edge.
When this happens, their dethatching performance
will diminish. A new combing edge may be obtained
by rotating the entire rotor shaft assembly laterally
(end to end). This procedure can be repeated until
the blades reach their wear limit; see illustration.
Rotate the rotor shaft as follows:
A. New blade
B. Worn blade
C. After rotation
3. Remove the belt guard (see illustration).
4. Remove the belt and pulley from the rotor shaft.
5. Remove the 6 bearing bolts and allow the rotor
shaft to slide out.
6. Check the shaft, bearing, blade length, blade
e-rings and spacers.
7. Rotate the shaft end for end.
8. Refit the bearing bolts.
9. Refit the pulley and check that it is aligned with
top pulley.
10. Refit the drive belt.
11. Check the pulley alignment to the engine shaft
pulley. The drive belt should run smoothly in
its track. Adjust as necessary. Tighten the
pulleys.
12. Refit the belt guard.
13. Reattach the spark plug cable.
Rotating the rotor shaft
1. Allow the engine to cool.
2. Disconnect the spark plug.
IMPORTANT INFORMATION
Only the flail blade rotor shaft can be rotated
to achieve even wear.
