	A. Tine Inspection:
Figure 5-4: Wheel gear cable assembly.	With use, the tines will become shorter,
	narrower and pointed (Figure 5-5). Badly
	worn tines will result in a loss of tilling

	chopping up and turning under organic
	matter. Use Figure 5-5 as a guide to
	when the tines should be replaced.

B. Removing a Single Tine:

1.Remove the two screws and nuts that attach a single tine to the tine holder (Figure 5-6). If needed, use penetrating oil to help free the nuts.

2.When installing a single tine, be sure to position it so that its cutting edge will enter the soil first as the tiller moves forward.

C. Removing a Tine Assembly:

1.If removing both tine assemblies, mark them “left” and “right” before removal. Doing so will help ensure that the assem- blies are reinstalled on the correct sides of the tiller.

2.Remove the screw and locknut that secure the tine assembly to the tine shaft (Photo 5-7). Pull the tine assembly off the shaft (if necessary, use a rubber mallet to tap the tine assembly outward).

3.Before reinstalling the tine assembly, inspect the tine shaft for rust, rough spots or burrs and file or sand as needed. Apply a thin coat of grease to the shaft.

4.Install each tine assembly so that the cutting edge of the tines will enter the soil first when the tiller moves forward. Secure the tine assembly to the tine shaft using the screw and locknut previously removed. Tighten securely.
