Tightening Tiller Hardware
A WARNING
Stop the engine, allow it to
cool, disconnect the spark
plug wire and prevent it from
touching the spark plug be¬
fore tightening any bolts,
screws, or nuts.
Failure to do so could result
in personal injury or property
damage.
After the first two hours of tiller
operation, check all fasteners (nuts,
bolts, screws, pins, etc.) and
tighten any that may have loosened.
After this initial check, check those
same fasteners after every ten
hours of tiller operation.
Most of the fasteners on your
tiller are in plain view. However,
the following ones are not readily
visible. Be sure to check them for
tightness as well.
1. Rear End Cap Bolts-These
three bolts are located at the rear
end of the tiller transmission. Lift
up the hood flap to view them.
2. Transmission Housing Cover
Bolts- These four bolts are lo¬
cated on the top of the rear end of
the tiller's transmission. You see
them when you lift the hood flap.
Boio Tines
As you use your tiller, the tines
will gradually wear. They will be¬
come shorter, narrower and
pointed, decreasing their ability to
till effectively. Check the tines for
wear several times a season, and
replace badly worn tines to restore
your tiller's effectiveness.

tine holder loose.
3. Slide the tine assembly off the
tine shaft.

to remove the other tine assembly.
5. Installing the tine assembly is
simply the reverse of its removal.

uneven spots or burrs from the tine
shaft, using fine sandpaper. Then
grease the tine shaft before rein¬
stalling the tine assemblies. Tight¬

lockwashers that secure the tine to
its tine holder. See Figure 5-12.
NOTE: If the nuts are rusted,
apply penetrating oil to the bolt
and nut. Let the oil soak in for
several minutes before loosening
the nut. Always loosen the nut
rather than the bolt.
3. When installing individual
tines, install them in the reverse
order from which they were re¬
moved. All tine tips must point in¬
ward toward the transmission.
Also be sure the cutting edges face
so they will enter the soil first
when the tiller is moving forward.
