Belt Replacement
If the drive belt or reverse drive belt needs to be replaced, see your 1.
local authorized dealer or refer to the Replacement Parts Section
for ordering information. Use only a factory-authorized belt as 2.
an "over- the-counter" belt may not perform satisfactorily. The
procedure requires average mechanical ability and commonly
available tools.
NOTE:When reinstalling the belt cover, be sure to engage the
bail and hold it so that the drive belt is tight before attempting to
reinstall the belt cover. This will enable the belt to fall under the
belt keeping mechanism built into the belt cover. Failure to do so
could damage the belt and/or belt cover.
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.
TineInspection
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 Fig. 7-1 for the following tine procedures.

Removing/Installing aSingleTine
1. With the engine shut off and the spark plug wire
disconnected, remove the two hex screws (3/8-16x 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.
Rem0ving/Installing aTineAssembly:
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 hex screw (3/8-16x 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 offthe shaft.
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.
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 Iocknut.

NOTE:The transmission gear oil does not need to be changed
unless it has been contaminated with dirt, sand or metal
particles.
1. Drain the gasoline from the fuel tank or run the engine
until the fuel tank is empty.
2. Drain the oil from the engine.
