TINE REMOVAL AND REPLACEMENT
All 4 tines should be replaced at the same time because they will wear evenly through normal use. Work on one side at a time.
WARNING: To prevent serious injury, always wear
heavy gloves when handling the tines.
1.Put the On/Off Stop Control in the STOP (O) position and disconnect the spark plug boot from the plug.
NOTE: It may be necessary to lay the cultivator back in a horizontal position on a flat level surface with the handles touching the ground.
2. | Remove the click pin from each end of the tine shaft. |
| Slide the tines off of the shaft (Fig. 12a). |

4. When you are reinstalling tines, lay out the tines and |
compare them to those shown in Figure 12b. Note |
specifics about each tine: its hub, curvature and |
lettering (“A” or “B”). This will help make sure that |
you are placing the correct tines in the correct order. |
NOTE: If you look closely, you can see a slight curvature in the tine tips. These curves should point toward the front of the cultivator when the tines are installed. Figure 12b shows the curve in each tine.
5. | Using Figures 12a and 12b for reference, slide on the |
| new tines with the hubs facing outward. |
| The tines are stamped “A” or “B.” The tine order |
| should be “B, A, B, A” from left to right when facing |
| the cultivator from the front. |
6. | Secure the new tines to the shaft with click pins. It |
| may be necessary to wash the dirt off the tines and |
| shaft to help during this entire process. |
