TINE REMOVAL AND REPLACEMENT
All 4 tines should be replaced at the same time because
they will wear evenly through normal use. Work on one
side at a time.
WARNING: To prevent serious personal
injury, always wear heavy gloves when
handling the tines.
1. Put the On/Off Stop Control in the STOP (O) position
and disconnect the spark plug wire.
2. Remove the clevis pin clips and clevis pins (Fig. 15).
3. Remove the tines and felt cushions from the shaft.
4. Clean and oil the shaft.
5. Replace the tines and felt cushions by reversing
steps 2 and 3 (Fig. 16).
NOTE: When installed correctly, the hubs on the tines
will face each other and the letter “R” stamped
on the tines will appear on the right side of the
cultivator and the letter “L” will appear on the
left side from the normal operating position. It is
important that the tines are installed correctly.
6. Repeat this procedure on the opposite side.
