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 machine 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 (9 cm), they should be replaced or straightened as necessary. • New tines should be assembled as shown in Fig. 28. Sharpened tine edges will rotate rearward from above. tine_3 NEW TINE WORN TINE FIG. 24 COUNTER TINE ROTATION SHARP EDGE TINE 3-1/2" MAX (9 CM) FIG. 25 TINE SHARP EDGE HAIRPIN CLIP SHARP EDGE 02050 SHARP EDGE SHEAR PIN SHARP EDGES SHARP EDtiGneE_13 FIG. 26 16
