Service

WARNING! Disconnect the spark plug wire
and ground it against the engine before
performing any maintenance or repairs.
Maintenance
Engine
Refer to the separate Engine Operator's Manual for
engine maintenance instructions.
Tires
Recommended operating tire pressure is
approximately 20 p.s.i. on 16 inch tires. (Check
the sidewall of the tire for the manufacturer's
recommended pressure). Maximum tire pressure
under any circumstances is 30 p.s.i. Equal tire
pressure should be maintained on both tires.
WARNING! Excessive pressure (over 30
p.s.i.) when seating beads may cause the
tire/rim assembly to burst with force
sufficient to cause serious injury.
Tines
Clean the underside of the tine shield after each
use. The dirt washes off the tines easier if rinsed off
immediately instead of after it dries. Always towel
dry the tiller afterwards and apply a light coat of oil
or silicone to prevent rusting or water damage.
NOTE: Never use a "pressure washer" to clean
your tiller. Water can penetrate tight areas of
the tiller and its chain case and cause serious
damage to the tiller.
Lubrication
Transmission
The transmission is pre-lubricated and sealed at
the factory. It requires no checking unless the
transmission is disassembled. To fill with grease, lay
the right half of the transmission on its side, add 22
ounces of Benalene 920 grease, and assemble the left
half to it. This grease can be obtained at your nearest
authorized dealer by ordering part number 737-0300
or calling the Customer Support number on page 2.
Clutch Handle
Lubricate the pivot point on the clutch handle and
the cable at least once a season with light oil. The
control must operate freely in both directions.
Pivot Points
Lubricate all the pivot points and linkages at least
once a season with light oil.
Tine Shafts
Remove the tine assemblies and lubricate the tine
shafts at least once a season.
Wheel Shafts
Remove the wheel assemblies and lubricate the axle
shafts at least once a season.
Adjustments
WARNING! Never attempt to make any
adjustments while the engine is running,
except where specified in the Operator's
Manual.
Engine Adjustment
Refer to the separate Engine Operator's Manual for
engine adjustment instructions.
Clutch Cable
Refer to the Assembly & Set-Up section of this manual
for instructions on adjusting the clutch cable.
Idler Pulley Rod
After the belt tension has been adjusted, if the belt
is excessively stretched, you may need to adjust the
idler pulley rod. This can be checked easily.
With the engine off and the clutch control bail
disengaged, shift the gear selection handle to each
forward mode. If the indicator bracket touches
the idler pulley rod with the clutch control bail
disengaged, then an adjustment is necessary.
1. Disconnect and ground the spark plug wire
against the engine.
2. Remove the belt cover as described under Belt
Replacement in the Service section.
3. Remove the cotter pin and spring washer from
the idler pulley rod. See Figure 4-1.

4. Move the idler pulley rod to the lower hole in
the idler bracket.
5. Replace the spring washer and hairpin clip.
6. Check the clearance of the idler pulley rod to the
indicator bracket by shifting to each forward mode.
Handle
The handle may be adjusted to the desired height.
Refer to the Assembly & Set-Up section for details.

Your tiller has been engineered with a belt designed
for long life and optimal performance. It should
never be replaced with a non-OEM belt. Order all
belts through an authorized service dealer or by
contacting Customer Support.
1. Disconnect and ground the spark plug wire
against the engine.
2. Remove the belt cover from the left side of the
tiller by removing the two screws from the top
of the belt cover. See Figure 4-2.

NOTE: Upon reassembly, make certain the belt
is routed over the idler pulley and inside of
belt keepers by the engine pulley.
Secondary Cable Adjustment
If additional adjustment is necessary after the
primary adjustment can no longer be used, the
secondary adjustment can be performed as follows:
1. Remove the belt cover as instructed in the Belt
Replacement section above.
2. Locate the spring at the end of the cable. See
Figure 4-4.
3. Loosen the upper nut, then tighten or loosen the
lower nut until the proper tension is reached.
