SECTION 5:  MAKING ADJUSTMENTS

WARNING: 

Never attempt to make any

adjustments while the engine is running,
except where specified in operator’s
manual.

Handle Adjustment

The handle height may be adjusted to the desired 
height. Refer to the handle adjustment in Know Your 
Tiller section.

Belt Tension Adjustment

Periodic adjustment of the belt tension may be required 
due to normal stretch and wear on the belt. Adjustment 
is needed if the tines or wheels seem to hesitate while 
turning, but the engine maintains the same speed.

To adjust the tension on the belt, refer to Final Clutch 
Adjustment in Assembly Instructions.

After belt tension has been adjusted, if the belt is 
excessively stretched, you may need to adjust the idler 
pulley rod. This can easily be checked.

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.

Disconnect and ground out spark plug wire against 
the engine.

Remove the belt cover as described under Belt 
Replacement in the Maintenance section.

Remove the hairpin clip and spring washer from the 
idler pulley rod. Refer to Figure 9.

Move the idler pulley rod to the lower hole in the 
idler bracket.

Replace the spring washer and hairpin clip.

Check clearance of the idler pulley rod to the 
indicator bracket by shifting to each forward mode, 
as before.

Engine Adjustment

Refer to the separate engine manual for engine 
adjustment instructions.

SECTION 6:  MAINTAINING YOUR TILLER

WARNING: 

Disconnect the spark plug

wire and ground it against the engine
before performing any repairs or
maintenance.

Engine

Refer to the separate engine manual for engine 
maintenance instructions.

Maintain 

engine oil

 as instructed in the separate 

engine manual packed with your unit. Read and follow 
instructions carefully.

Service 

air cleaner

 every ten hours under normal 

conditions. Clean every hour under extremely dusty 
conditions. Poor engine performance and flooding 
usually indicates that the air cleaner should be 
serviced. To service the air cleaner, refer to the 
separate engine manual packed with your unit.

IMPORTANT:

 Never run your engine without air cleaner 

completely assembled.

The 

spark plug

 should be cleaned and the gap reset 

every 25 hours of engine operation. Spark plug 
replacement is recommended at the start of each tiller 
season; check engine manual for correct plug type and 
gap specification.

Clean the engine

 regularly with a cloth or brush. Keep 

the cooling system (blower housing area) clean to 
permit proper air circulation which is essential to engine 
performance and life. Be certain to remove all dirt and 
combustible debris from muffler area.

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.

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 pivot points and linkages at least once a 
season with light oil.

Tine Shafts

Remove tine assemblies and lubricate the tine shafts at 
least once a season.
