•  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.
•  For tines that are slightly worn, the bolt ed tine and 
hub assemblies can be switched between sides to 
continue till ing in the same tilling mode if tilling in a 
different mode is desired then the bolt ed tine and hub 
assemblies should be switched back to their original side 
so that the tine edge with the least wear will be used.

TINE REPLACEMENT 
(See Figs.  27, 28 and 29)
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.
