MAINTENANCE
Wear/Replacing delta blades
Over time and due to wear, the blades will diminish in length. Once the blades have worn down by about
19 mm (3/4"), the overall length of the blade at the longest point of the blade will be about 64
mm(2 1/2"), and it will be necessary to replace the blades.
It is possible to replace delta blades without removing the rotor shaft. Remove the delta blade by removing the two screws with nuts holding the blade in place.
Turn the new blade until it is properly aligned; see illustration.

Wear/Replacing spring tines
Over time and due to wear, the tines will diminish in length. When the tines can no longer be adjusted to comb 6 mm (1/4") into the soil, the tines must be replaced.
Spring tines can be replaced without removing
the rotor shaft by using a 1/2" socket wrench. Remove the screw and replace the spring tine using the wrench. Fit the new spring tine before removing the tine on the opposite side.
