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.
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.
