BOLO TINES
The bolo tines will wear with use and
should be inspected at the beginning of
each tilling season and after every 30
operating hours. Tines can be replaced
individually or as a complete set. Never
inspect or service the tines unless the
engine is stopped, the spark plug wire is
disconnected, and the ignition key is
removed on electric start models.
A. T ine Inspection:
With use, the tines will become shorter,
narrower and pointed (Figure 5-6). Badly
worn tines will result in a loss of tilling
depth and reduced effectiveness when
chopping up and turning under organic
matter. Use Figure 5-6 as a guide to
when the tines should be replaced.
Figure 5-6: Checking tines for wear.
B. R emoving a Single Tine:
1. With the engine shut off and the spark
plug wire disconnected, remove the two
bolts and nuts that attach a single tine to
the tine holder (Figure 5-7). 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. R emoving a Tine Assembly:
1. With the engine shut off and the spark
plug wire disconnected, remove the tine
hood by removing the two attaching
screws at the rear of the hood and the
two attaching screws at the front of the
hood.
2. If removing both tine assemblies, mark
them “left” and “right” before removal.
Remove the screw and locknut that
secure the tine assembly to the tine shaft
(Photo 5-8). 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 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.
