SERVICE AND ADJUSTMENTS
TINE REPLACEMENT (See Figs. 24, 25 and
26)
CAUTION: Tines are sharp. Wear gloves
or other protection when handling 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 exceeds 3-
1/2 inches they should be replaced or straightened as
necessary.
• New tines should be assembled as shown in Fig. 26.
Sharpened tine edges will rotate rearward from above.
