C. 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 ship-
ment.) 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 operating range.
Note:
Gasoline Engine: For the recommended 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
an expansion tank which should be maintained
with a 1/2” to 1” above the bottom.
d. Tires: 8-10 psi rear, 20-25 psi front caster tires
Note:
New tires are overinflated in order to prop-
erly 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 main-
tained by a spring mechanism that adjusts for
wear and stretch.
c. Examine the belts for cuts, fraying, and exces-
sive 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".
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 con-
nection 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 surface to the
bottom edge of the mowing blade at the front
and the back of the deck on each side of the
mower. (Four dimensions.)
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
wrench loosen the top jam nut of the left side of
the Lift Link. To adjust the side of the deck up
or down turn the jam nut clockwise or counter
clockwise a few turns.
e. To change the pitch (front to rear), loosen the
top nuts on the rear Lift Links. With a few
turns, adjust clockwise or counter clockwise
the lower nuts of the rear Lift Links. Once the
deck is adjusted, retighten upper 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.
5. Lubricate all fittings listed in the maintenance
section.
D. Zero Turn Break-In And Operating Pro-
cedures
DANGER:
Reread the “When Mowing” Safety Precautions.
The following procedures are suggested for operators of
ride-on machines which have zero turn capabilities.
