Removing and Sharpening Blades. See figure 20.
Each blade is secured to the blade mount adapter
plate wtih two bolts, nuts and lockwashers. The
blade is removed by removing these bolts and
nuts and pulling the blade away from the adapter.
When replacing the blades be sure the blade
offset and the sharp edges are positioned as
shown at the right. Tighten the retaining boltssecurely.
Do not re-use worn or stri pped
fasteners.
FIGURE 20. BLADE REMOVALADJUSTMENTS
~ CAUTION
MAKE ALL ADJUSTMENTS (RE-
GARDLESS OF HOW MINOR) WITH
THE IGNITION KEY IN THE OFF PO-
SITION, WITH THE IGNITION WIRE
REMOVED AND SECURED AT
LEAST 1 " AWAY FROM THE SPARK
PLUG, WITH THE SHIFT LEVER IN
NEUTRAL AND THE BLADE CON-
TROL LEVER IN THE OFF POSI-
ION. IN ADDITION THE WHEEL
SHOULD BE BLOCKED TO PRE-
VENT ACCIDENTAL MOVEMENT.
5. Each time you use the rider be sure you check
the condition of the nuts, bolts, cotter pins,
etc. to be sure all are tight and secure
properly.
6. The transaxle transmission is pre-lubricated
at the factory. Check the oil level every 25
hours by removing the oil fill plug. If the oil is
below the level of the plug opening, fill to that
level with SAE 90 extra heavy duty
transmission oil.
Transmission oil should be changed every 50
hours of operation or once each season.
7. The disc brake pads wear and may require
replaci ng occasionally. Th is replacement is
best done by a qualified service dealer.
& CAUTION
Brakes should be kept in good oper-
ating condition to avoid possible in-
jury or damage to the operator or
tractor.
8. Should excessive vibration develop, check for
the cause immediately. Check for a damaged
blade, damaged bearing shaft, frayed belt, an
obstruction, etc. DO NOT operate the rider
again until the cause is found and corrected.
SPARK PLUG
The spark plug gap should be cleaned and reset to
a 0.030-inch clearance once a season (see figure19).
Spark pi ug replacement is recommended at
the start of each mowing season.
~ NOTE
Whenever the spark plug is removed
for cleaning, it is advisable to re-
place the spark plug gasket with a
new gasket.

NOTE
To insure safe operation of your
unit, ALL nuts and bolts must be
checked periodically for correct
tightness.
WHEEL ADJUSTMENT
The caster (forward slant of the king pin) and the
camber (tilt of the wheels out at the top) requires
no adjustment. Automotive steering principals
have been used to determine the caster and
camber on the tractor. The front wheels should
toe-in 1/8 inch.
Before beginning work on the cutterblade,
remove the spark plug fromthe
cylinder.
