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).

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).
