G. Initial Adjustments
1. Check the fluid levels and tires:
Note:
These checks should be made daily,
before starting the engine.
a. Fuel: Using a good grade of unleaded,
regular gasoline, fill the fuel tank (beside
the engine on the left side of the mower).
When the fuel reaches one inch from the
top of the tank, stop. DO NOT OVERFILL.
Space must be left for expansion.
b. Engine Oil: (Filled at the factory before
shipment.) Pull out the oil dipstick, wipe it
off and reinsert it. Pull it out again and read
the oil level. If it is below the operating
range, add oil through the fill tube using a
funnel to bring it up to the top of the operat-
ing range.
Note:
Gasoline Engine: For the recom-
mended oil weight refer to engine manual.
c. Hydraulic Oil: (Filled at the factory before
shipment.) The hydraulic oil is contained
within the integrated hydrostatic transaxles
and does not need to be checked or
replaced. The oil level in the expansion
tank needs to be maintained at 1/2" to 1"
above the bottom of the tank.
d. Tires: 8-10 psi rear, 20-25 psi front caster
tires
Note:
New tires are overinflated in order to
properly seat the bead to the rim. The normal
working pressure for the traction tires is 8-10
psi. The front caster wheels should be inflated
to 20-25 psi.
2. Check that all Nuts, Bolts and Screws are
Tight.
3. Check the tension of the deck drive belts.
a.
Remove the deck cover
b.
The tension of the deck drive belts are
maintained by a spring mechanism that
adjusts for wear and stretch.
c.
Examine the belts for cuts, fraying, and
excessive wear. Replace if any of these
are detected.
d.
Replace the deck cover.
4. Adjust the Mowing Deck: The cutting height
is set in 1/4" increments in the range of 1-1/2"
to 4". Do not attempt to raise the mower deck
higher than 4" because you will damage com-
ponents on your mower. You may need to
adjust the mowing deck to achieve the proper
angle for mowing. Follow the procedures
below to set the appropriate angle to the
mowing deck.
a. Park the mower on a flat paved surface,
engage the parking brake, shut off the
engine, remove the key from the ignition
switch, remove connection of the spark
plugs and using the foot pedal, lower the
mowing deck into the cutting position.
b. Using a ruler, pencil and paper, measure
and note the distance from the paved sur-
face to the bottom edge of the mowing
blade at the front and the back of the deck
on each side of the mower. (Four dimen-
sions.)
Note:
The front edge of the mowing deck
should be 1/8"-1/4" below the rear edge of the
deck so that the blades are cutting grass in
only the front half of their circular path. This
decreases friction and reduces the drive
power required.
c. If the dimension at the front of the mowing
deck is 1/8"-1/4" lower than the dimension
at the rear of the deck (pitch) on each side
of the mower, do not adjust. If not, you will
need to adjust the Lift Links (See Figure 5).

d. To level the deck (side to side), place the
deck in the (3" suggested) cutting position.
With a 3/4" wrench loosen the lower jam
nut of the left side of the Lift Link. To adjust
the side of the deck up or down turn the
upper jam nut clockwise (to raise) or
counter clockwise (to lower) a few turns.
e. To change the pitch (front to rear), loosen
the lower nuts on the rear Lift Links. With a
few turns, adjust clockwise (to raise) or
counter clockwise (to lower) the upper nuts
of the rear Lift Links. Once the deck is
adjusted, retighten lower nuts.
f.
Raise the mowing deck to the transport
position using the deck lift pedal.
g. Use the deck lift pedal to lower the mowing
deck to the cutting position and repeat step
"b." above to make sure that the desired
cutting height and pitch and level have
been attained. If the dimensions are not
correct, repeat steps "c." through "f." above.
