blade to prevent accidental engine start-
ing. Protect hands by using heavy gloves
or a rag to grasp the cutting blades.
1. Remove the large bolt and lock washer which holds
the blade and adapter to the blade spindle.
2. Remove the blade and adapter from the spindle.
3. If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and nuts
which hold the blade to the adapter.
B. Sharpening
Remove the cutting blades by following the directions
of the preceding section.
When sharpening the blades, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high speeds,
may cause damage to the mower and could break,
causing personal injury.
The blade can be tested for balance by balancing it on
a round shaft screwdriver. Remove metal from the
heavy side until it balances evenly.
NOTE: It is recommended that the blade always be
removed from the adapter for the best test of balance.C.
Reassembly
Before reassembling the blade and the blade adapter
to the unit, lubricate the spindle and the inner surface
of the blade adapter with light oil. Lubricating the bolt
holes, bolts and inner surface of the nuts with light oil
is also recommended. A 4 oz. p'lastic bottle of light oil

FUEL FILTER
Your unit is equipped with a replaceable in-line fuel
filter. Replace filter whenever contamination or
discoloration is noticed. Order replacement filter
through your authorized engine service dealer.
CLEANING ENGINE AND DECK
Any fuel or oil spilled on the machine should be wiped
off promptly. Grass, leaves, and other dirt must not be
left to accumulate around the cooling fins of the engine
or on any part of the machine.
Clean the underside of the deck after each mowing.
WHEEL ADJUSTMENT
The caster (forward slant of the king pin) and the
camber (tilt of the wheels out at the top) require no ad-
justment. Automotive steering principles have been
used to determine the caster and camber on the trac-
tor. The front wheels should toe-in 1/8 inch.
To adjust the toe-in, follow these steps.
1. Remove the hex nut and lock washer, and drop
the end of the tie rod from the axle bracket. See
figure 20.
2. Loosen the hex jam nut on tie rod.
3. Adjust the tie rod assembly for correct toe-in.
