TINE REPLACEMENT  

 

 

 

(See Figs. 24, 25 and 26)

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.

FIG. 25

•     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.

•     New tines should be assembled as shown in Fig. 

26.  Sharp ened tine edges will rotate rearward from 
above.
