SERVICE AND ADJUSTMENTS
TINE REPLACEMENT (See Figs. 24, 25 and
26)
CAUTION:
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 they should be replaced or straight ened
as necessary.
• New tines should be assembled as shown in Fig.
X3. Sharp ened tine edges will rotate rearward from
above.
