Tine Inspection
The bolo tines will wear with use and should be inspected at the beginning of
each tilling season and after every 30 operating hours. The tines can be replaced
either individually or as a complete set. See the Replacement Parts section for tine
identification and part numbers.
With use, the tines will become shorter, narrower and pointed. Badly worn tines will
result in a loss of tilling depth, and reduced effectiveness when chopping up and turning
under organic matter.
Refer to Figure 21 for the following tine procedures.

Removing/Installing a Single Tine
1. With the engine shut off and the spark plug wire disconnected, remove the
two hex screws (3⁄8-16 x 1.00) and hex lock nuts (3⁄8-16) that attach a single
tine to a tine holder. If needed, use penetrating oil on the nuts.
2. When installing a single tine, be sure to position it so that its cutting edge
(sharp) will enter the soil first as the tiller moves forward.
Removing/Installing a Tine Assembly:
1. A tine assembly consists of eight tines mounted on a tine holder.
2. If removing both tine assemblies, mark them "left" and "right" before removal.
Remove the hex screw (3⁄8-16 x 1.75) and flange lock nut (3⁄8-16 ) that secure
the tine assembly to the tine shaft. If necessary, use a rubber mallet to tap the
tine assembly outward off the shaft.
3. Before reinstalling the tine assembly, inspect the tine shaft for rust, rough
spots or burrs. Lightly file or sand, as needed. Apply a thin coat of grease to
the shaft.
4. Install each tine assembly so that the cutting (sharp) 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.
