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: Use SAE 10W30 or
SAE 10W40 engine oil, rated for service SJ. Shell
Rimula 15W40 is also recommended and provides
service SL and CI-4 plus.
c.
Hydraulic Oil:
(Filled at the factory before
shipment.) The hydraulic oil tank is located
beneath the operator’s seat. Always wipe off
the area around the oil tank fill neck before
checking the oil level to prevent dirt from con-
taminating the oil. Remove the cap and make
sure the oil level is a 1/4” below the oil tank fill
neck. If the oil level is low, fill with Shell Rimula
15W40 or equivalent oil. Equivalent oil should
meet GM Allison C-4.
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 main-
tained 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 anywhere in the range of 1" to 5". You may
need to adjust the mowing deck to achieve the
proper pitch angle for mowing. Follow the proce-
dures 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 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" (1/8” for 1-1/2”, 1/16” for 1”)
below the rear edge of the deck so that the blades
are cutting grass in only the front half of their cir-
cular 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" (1/8” for 1-1/2”, 1/16” for 1”)
lower than the dimension at the rear of the
deck on each side of the mower, do not adjust.
If not, you will need to adjust the Deck Lift
Spring Assist (See Figure 5). You may also
need to adjust the Deck Links (See Figure 5).

Figure. 5
d.
Lower the mower deck to the cutting position.
With a wrench loosen the lower rear nut on
the Deck Lift Links. To adjust the deck up or
down, use a wrench and with a few turns,
adjust clockwise or counter clockwise the
upper rear nut of the Deck Lift Links. Repeat
this procedure on the opposite side of the
Mower. Once the deck is adjusted, retighten
nuts.
e.
Raise the mowing deck to the transport posi-
tion using the foot pedal.
f.
Use the foot pedal to lower the mowing deck
to the cutting position and repeat step “b.”
above to make sure that the desired cutting
height has been attained. If the dimensions
are not correct, repeat steps “c.” through “e.”
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.
1.
Orientation:
a.
Read the entire Operator’s Manual.
b.
Sit on the machine, adjust the seat before-
and-after, then adjust the speed/directional
(lap bar) controls (they can be adjusted fore-
and-aft, as well as up-and-down — 9/16"
wrench required).
