Belt Replacement
If the drive belt needs to be replaced, see your local authorized
dealer or refer to the Replacement Parts Section for ordering
information. Use only a factory-authorized belt as an "over- the-
counter" belt may not perform satisfactorily. The procedure
requires average mechanical ability and commonly available
tools.
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. The tines can be replaced either individually
or as a complete set. See the Replacement Parts Section for tine
identification and part numbers.
Tine Inspection
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.

Removing/Installing a Tine Assembly:
1.
A tine assembly consists of eight tines mounted on a tine
holder.

If removing both tine assemblies, mark them "left" and
"right" before removal. Remove the screw and locknut that

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.\
