SAFETY PRECAUTIONS
A. General
1. Read this Operator’s Manual before starting the mower. Study the
controls and learn the proper sequence of operation.
2. Do not allow anyone to operate or maintain this machine who has
not read this manual. Never permit children to operate this
machine.
3. Never carry passengers.
4. Do not remove any shields, guards or safety devices. If a shield,
guard or safety device is damaged or does not function, repair or
replace it before operating the mower.
5. Always wear safety glasses and safety shoes when operating or
maintaining this mower. Do not wear loose-fitting clothing.
6. Disconnect the spark plug wires or remove the key from the ignition
to prevent the engine from accidentally starting before performing
any maintenance on this mower.
7. Never run the engine indoors without adequate ventilation. Exhaust
fumes are deadly.
8. To avoid serious burns, do not touch the engine, exhaust pipe or
muffler while the engine is running or until it has cooled after it has
been shut off.
9. The liquid in the battery is dilute sulfuric acid. Always wear safety
glasses and rubber gloves when working on the battery. Do not
overfill the battery.
10. Lead-acid batteries generate hydrogen and oxygen gases which
form an explosive mixture. Keep sparks and flames away at all
times.
11. When looking for oil leaks, never run your hand over hydraulic
hoses, lines or fittings. Never tighten or adjust hydraulic hoses,
lines or fittings while the system is under pressure. If high-pressure
oil penetrates the skin, the oil must be removed within a few hours
by a doctor familiar with this form of injury or serious complications
may result.
B. Related to Fuel
1. Fuel is highly flammable. Please respect it.
2. Do not smoke or permit others to smoke while handling fuel.
3. Always use approved containers for fuel.
4. Always shut off the engine and permit it to cool before removing the
fuel tank cap.
5. Always fill the fuel tank outdoors.
6. If the fuel container spout will not fit inside the fuel tank opening,
use a funnel.

7. When filling the fuel tank, stop when the fuel reaches one inch from the
top. This space is necessary for tank expansion.
Do not overfill
.
8. Wipe up any spilled fuel.
C. When Mowing
1. Keep adults, children and pets away from the area to be mowed.
2. When operating this mower in the forward direction, DO NOT allow
the steering levers to return to the neutral position on their own.
Always maintain a firm grip on the levers, operate them smoothly
and avoid any sudden movements of the levers when starting or
stopping.
3. If the mower is equipped for side discharge, never use the mower
without the discharge chute installed and placed in the down posi-
tion.
4. Always remove debris and other objects from the area to be
mowed.(
Note
: debris and loose grass will reduce traction.)
5. Mow only in daylight.
6. Watch for holes, sprinkler heads and other hidden hazards.
7. Avoid driving too close to trees, creeks, ditches, sand traps and
other obstacles.
8. Before backing up, check behind you and watch where you’re
going.
9. Always reduce speed when making a turn, and when grass is wet.
10. Always mow across slopes, never up and down the slope. Do not
operate on steep slopes and slow down before turning.
11. Be careful when crossing gravel paths or roadways. Always turn off
the blade clutch switch and wait until the blades stop rotating and
raise the cutting deck to the transport position. Always allow other
vehicles to have the right-of-way.
12. If you hit a solid object while mowing, turn off the blade clutch
switch, place the left and right steering levers in the neutral,
opened-out position, move the throttle to slow, set the parking
brake, shut off the engine and take the key from the ignition switch.
Inspect for damage. Repair any damage. Make sure the blades are
in good condition and that the blade bolts are tight before restarting
the engine.
13. Never leave the mower unattended without: turning off the blade
clutch switch; placing the left and right steering levers in the neutral
opened-out position; moving the throttle to slow; setting the parking

brake; shutting off the engine and taking the key from the ignition
switch.
14. Never walk or stand on the discharge side of a mower with the
engine running. Turn off the blade clutch switch if another person
approaches while you are operating the mower.
15. Never attempt to operate the traction unit without the mowing deck
attached.
16. Keep the mower and especially the engine and hydraulic compo-
nents clean and free of grease, grass and leaves to reduce the
chance of fire and to permit proper cooling.

OPERATING INSTRUCTIONS
A. Controls
1.
Engine Ignition and Start Switch:
(See Figure 1.) Located on the
instrument housing below the right side of the operator’s seat.
When the key is inserted and turned clockwise, 45 degrees, the
ignition circuit is closed. Turning the switch further against spring
pressure starts the engine. The engine will only start if the blade
clutch switch is in the “off” position, the parking brake is engaged
and the left and right steering levers are in the neutral, opened-out
position. The key should always be removed from the switch if the
operator leaves the mower’s seat.
2.
Engine Throttle Control:
(See Figure 2.) Located on the left side
of the mower next to the operator’s seat. Moving the throttle control
from the rear to the front will increase the engine speed from slow
to fast.
3.
Left and Right Steering Levers:
(See Figure 3.) These hinged
levers open out to the side in the neutral position to permit the
operator to be seated or to leave the mower’s seat. The operator,
when seated, can pull the levers up to the operating position, a
comfortable forearm’s length away. These levers control all of the
movements of the mower.
In order to start the engine, both steering levers must be opened
out to the side in the neutral position; the parking brake must be
engaged; and the blade clutch switch must be “off”. However, once
the engine starts, the parking brake must be released before the
operator places the steering levers into the operating position or
the engine will automatically shut off.

Note:The Steering Lever will return toward neutral when released, but they
should be placed in neutral by the driver. If the Drive Handles are not placed in neutral,
the tractor may creep.
4.
Electric Blade Clutch Switch:
(See Figure 1.) Located on the
right side of the mower behind the ignition switch. This is an “on/
off” toggle switch that controls the electric blade clutch which sup-
plies power to the cutting blades through the PTO. The switch must
be turned off to start the engine and should be turned off for safety
any time another person approaches the mower or the mowing
deck is raised to the transport position. Power to the electric clutch
will also be cut off if the operator leaves the operator’s seat.
5.
Parking Brake:
(See Figure 3.) Located on the left side of the trac-
tion unit. The handle is an overcenter lever which applies the inter-
nal drum-type brake on each drive wheel when the handle is pulled
to the rear. The brake must be engaged in order to start the engine.
6.
Deck Lift Handle:
(See Figure 3.)
Located on the right front corner of
the mowing deck.To raise the mowing
deck to the transport position, the
lever is pulled to the rear and moved
inward to lock into a stop for trans-
port. To lower the mowing deck, raise
the deck lift handle and move it out-
ward. This allows the handle to move
forward, lowering the deck to the cut-
ting position.
7.
Fuel Shutoff Valve:
(See Figure 4.)
Located on top of the fuel tank. When
turned in a clockwise direction until it
stops, it will shut off the flow of fuel to
the engine. When turned in a coun-
terclockwise direction it will open and
allow fuel to flow to the engine. Close
this valve if you are not going to run
the mower for a period of 30 minutes
or more to prevent flooding the
engine.
8.
Seat Adjustment Lever:
The Seat
Adjustment Lever is located beneath the seat. The Seat Adjust-
ment Lever is used to move the seat forward and backward. To
place the seat in the desired position pull the seat adjustment lever

to the left then push the seat forward or back to the desired posi-
tion. Release the lever so the seat will lock in place.
9.
Digital Tachometer and Hour Meter:
(See Figure 1) Located on
the right side of the mower of the ignition switch. When the
machine is running the tachometer displays engine rpm. When the
machine is off the tachometer displays running time.
Note:There will be a flashing “LUBE” for each recommended lubrication interval.
There is a flashing “OIL” at each recommended engine oil and filter change. Flashing
of “Lube” or “Oil” will continue for 1 hour regardless of maintenance done to the unit.
10.
Choke Lever:
(See Figure 2) The Choke Lever is located on the
left instrument panel next to the seat. The Choke Lever is operated
manually. Having the Choke Lever in the ON position helps the
engine to start during initial start-up. During normal operation the
Choke Lever should be in the OFF position.
B. Initial Adjustments and Service
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 (for
a gasoline engine), fill the fuel tank (beside the engine on
the left or right side of the mower). When the fuel reaches
one inch from the top of the tank, stop. DO NOT OVER-
FILL. 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 operating range.
Note:Gasoline Engine: Use SAE 10W30 or SAE 10W40 engine oil, rated for ser-
vice SJ.
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 contaminating the
oil. Remove the cap and make sure the oil level is up to the
lowest hole on the oil tank fill neck. The top hole is for vent-
ing. If the oil level is low, fill with a good grade of SAE20W-
50 oil.
d. Tires: 8-10 psi Rear, 25-30 psi Front Caster Tires
01004965.fm Page 9 Friday, March 23, 2001 9:17 AM

10
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 25-30 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
Proper Angle or Pitch:
The cutting height is set anywhere in the range of 1-1/2" to 5-1/2".
You may need to adjust the mowing deck to achieve the proper
angle for mowing. Follow the procedures below to set the appro-
priate 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, disconnect the spark plug wires and using the
transport lever, lower the mowing deck into the 4" height of
cut position. (The 4" height of cut position is recommended
in order for one to see and obtain a measurement. Any
height of cut position is acceptable as long as a proper
measurment can be taken.)
b. Using a ruler, pencil and paper, measure and note the dis-
tance 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: When mea-
susring
Note:The front blade edge of the mowing deck should be 1/8"-3/8" below the rear
blade 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.
Note:While adjusting the mower decks proper angle and side to side leveling,
raise and lower the deck in order for the deck to “settle”. Occasionally, if the deck is not
raised and lowered improper adjustment occurs. Improper adjustment especially
occurs when the unit is new and pivot points and linkages are caught up in “fresh”
paint.
