7. Before attempting to start the engine, move the
speed adjustment lever into the neutral position,
move the blade engagement switch to the OFF
position, apply the parking brake, and move the
neutral latches to neutral.
WHILE OPERATING
1. Start the engine when the neutral latches are in
the neutral lock position, the cutter blades are
disengaged, the parking brake is on and the speed
adjustment lever is in the neutral position.
2. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are ha ard-
ous and could possibly be deadly.
3. Using the machine demands attention. To
prevent loss of control:
A. Mow only in daylight or when there is good
artificial light.
B. Watch for holes or other hidden ha ards.
C. Do not drive close to a drop-off, ditch, creek
bank, or other ha ard.
D. Reduce speed when making sharp turns and
when turning on hillsides.
E. Always be sure of your footing. Keep a firm
hold on the handles and walk---never run.
F. Do not operate where conditions are slippery.
4. The discharge chute must always be installed and
in the down position on the side discharge cutter
deck except when the Scag optional grass
catcher or mulching plate are properly installed.
If the discharge area should plug, shut the engine
off and wait for all movement to stop before
removing the obstruction.
5. Disengage the blades and wait for them to stop
before crossing gravel drives, walks or roads.
6. Shut the engine off and wait until the blades
come to a complete stop before removing the
grass catcher container.
7. Never raise the cutter deck while the blades are
rotating.
8. Always park the mower and/or start the engine
on a level surface. Apply the parking brake to
prevent the mower from moving when you are

9. If the cutting blades should strike a solid object
or the equipment should start to vibrate abnor-
mally, stop the engine, disconnect the spark plug
wire, and check immediately for the cause.
Vibration is generally a warning of trouble.
Check the machine for damaged or defective
parts. Repair any damage before starting the
engine or operating the cutter deck. Be sure the
blades are in good condition and the blade bolts
are tight.
10. Reduce speed and exercise extreme caution on
slopes and in sharp turns to prevent tipping or
loss of control. Be especially cautious when
changing directions on slopes.
DO NOT operate on steep slopes. To check a
slope, attempt to back up it (with the cutter deck
down). If the machine can back up the slope
without the wheels slipping, reduce speed and
use extreme caution. ALWAYS FOLLOW OSHA
APPROVED OPERATION.
11. Do not touch the engine or muffler while the
engine is running or soon after it is stopped.
These areas could be hot enough to cause a burn.
12. Before leaving the operators position or leaving
the mower unattended, move the speed adjust-
ment lever into the neutral position, place the
neutral latches in the neutral lock position, apply
the parking brake, and move the blade engage-
ment switch to OFF. Shut the engine OFF and
remove the key.
13. Do not pass or stand on the grass discharge side
of any mower with the engine running. Stop
operation when another person approaches.
14. Use only Scag approved riding attachments.
Scag Approved Riding Attachments:
RS-ZT
Using unapproved attachments, (especially "stand-
up" riding attachments) may be ha ardous.
MAINTENANCE AND STORAGE
1. Disconnect the spark plug wire from the spark
plug to prevent accidental starting of the engine
when servicing, adjusting or storing the machine.
2. If the mower must be tipped to perform mainte-
nance or adjustment, remove the battery, drain
the gasoline from the fuel tank and the oil from
the crankcase.
3. To reduce potential fire ha ard, keep the engine
free of excessive grease, grass, leaves and accu-
mulations of dirt.
4. Be sure the machine is in safe operating condition
by keeping nuts, bolts, and screws tight. Check
the blade mounting bolts and nuts frequently to
be sure they are tightened.
5. If the engine must be running to perform a
maintenance adjustment, keep hands, feet, cloth-
ing and other parts of the body away from the
cutter deck blades and other moving parts.
6. Do not overspeed the engine by changing gover-
nor settings. To be sure of safety and accuracy,
have an authori ed dealer check maximum engine
speed with a tachometer.
7. The engine must be shut off before checking the
oil or adding oil to the crankcase.
8. Allow the engine to cool before storing the
mower in any enclosure such as a garage or
storage shed. Make sure the fuel tank is empty if

INITIAL RUN-IN PROCEDURES
(FIRST DAY OF USE OR APPROXI-
MATELY 10 HOURS)
1. Check the belts for proper tension at 2, 4 and 8
hours. Adjust as needed.
2. Check the steering control rods and the speed
control for neutral adjustment. (See Adjust
ments, page 6-8)
3. Check the tires for proper pressure.
Caster Wheels 25 psi.
Drive Wheels 15 psi.
4. Check for loose hardware. Tighten as needed.
5. Check the safety switches for proper adjustment:
* The engine should crank and start if the
machine is in neutral, the PTO engage-
ment switch is OFF and the parking brake
is ON.
6. Apply lubricant to all the grease fittings. Lubri-
cant was applied at the factory. This is just a
precautionary check to make sure that all the
fittings have been lubricated.
MOWER OPERATION
-NOTE-
Use gasoline with an octane rating no less than
87.
* The speed adjustment lever must be in
NEUTRAL.
* The blade clutch switch must be in the OFF
position.
* The neutral latches must be in the neutral
lock position.
* The key switch must be on.
* The parking brake must be on.
3. Start the engine:
* Choke as required. If the engine is cold, pull
the choke knob out. When the engine starts,
slowly push the choke in. If the engine stalls,
repeat the above operation. When the engine
is warm, choking may not be necessary.
4. Engage the cutter blades by lifting and pushing
the blade cluch switch into the ON position. Pull
the switch to the OFF position to disengage the
cutter blades.
-NOTE-
When PTO is engaged or (possibly) disengaged,
a squealing sound rom the underside o the
machine is normal. It is caused by the electric
clutch plates meshing as the mower comes up to
speed. For best equipment li e, engage the
clutch with the engine at 1/2 throttle, not under
ull load.
1. Read and understand the safety instructions
before attempting to operate this machine.
2. Before starting the engine:

CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is
difficult to suggest a cutter deck setting that will
work for every lawn. There are two adjustments
that can be made on these decks, pitch and height.
PITCH is the angle of the blades (comparing front
to rear). A 1/4" downward pitch (front of deck
down) is recommended for best cutting perfor-
mance.
HEIGHT is the nominal distance the blade is off of
the ground. This measurement is made with the
blades pointed side to side and distance is measured
between cutting tip and ground. (Also see Blade
Height Adjustment)
Changes to the cutting height can be achieved by
repositioning the cutter deck. (This adjustment will
also effect the pitch of the deck). There are three
available positions (see figure 4).

Caster spacers also can be repositioned to change
cutting heights and to change the pitch of the deck.
(See figure 5)

REPOSITIONING SPACERS
Figure 5. Caster Wheel Spacers
BLADE HEIGHT ADJUSTMENT
Adjusting the blade height can be done by moving
any number of the five smaller 1/4" spacers on the
blade mounting bolts to the top of the spindle shaft or
below the spindle shaft.
-NOTE-
All blades should be positioned equally.
For best cut and discharge, a minimum of three
spacers should be installed between the blade and the
spindle. (See figure 6)

7
CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade.
(See figure 7)
-NOTE-
Dress the blade with a ile. Using a wheel
grinder may burn the blade. Check the balance
o the blade. I blades are out o balance, vibra-
tion and premature wear o spindle assembly can
occur. See your authorized Scag dealer or
blade balancing or special tools, i you choose to
balance your own blades.
