MAINTENANCE

Flail Blades

Wear/Rotation/Replacing

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:

IMPORTANT INFORMATION

Only the flail blade rotor shaft can be rotated to achieve even wear. The spring tines and delta blades must be operated in the correct direction.
