SERVICE AND ADJUSTMENTS
TINE REPLACEMENT
(See Figs. 25, 26 and 27)
CAUTION: Tines are sharp. Wear
gloves or other protection when han-
dling tines.
A badly worn tine causes your tiller to work harder and dig
more shallow. Most important, worn tines cannot chop and
shred organic matter as effectively nor bury it as deeply as
good tines. A tine this worn needs to be replaced.

• To maintain the superb tilling performance of this
ma chine the tines should be checked for sharpness,
wear, and bending, particularly the tines which are
next to the transmission. If the gap between the tines
ex ceeds 3-1/2 inches (9 cm), they should be replaced
or straight ened as necessary.
• For tines that are slightly worn, the bolted tine and hub
assemblies can be switched between sides to continue
tilling in the same tilling mode. If tilling in different mode
is desired then the bolted tine and hub assemblies
should be switched back to their original side so that
the tine edge with the least wear will be used.
