WARNING
WARNING
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. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. See Figure 2-4, Page 7 to determine
approximate slope of area to be mowed. ALWAYS
FOLLOW OSHA APPROvED OPERATION.
This machine is equipped with an interlock system
intended to protect the operator and others from
injury. This is accomplished by preventing the
engine from starting unless the deck drive is
disengaged, the parking brake is on, the steering
control levers are in the neutral position and the
operator is in the seat. The system shuts off the
engine if the operator leaves the seat with the deck
drive engaged and/or the steering control levers
are not in the neutral position and the parking
brake is not engaged. Never operate equipment
with the interlock system disconnected or
malfunctioning.
2. 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.

WARNING
WARNING
Failure to properly inspect and maintain the seat
belt can cause serious injury or loss of life.
Reduce speed when turning, operating on slopes,
slick or wet surfaces. Allow extra distance to
stop.
Stay off of slopes too steep for safe operation.
To check a slope, attempt to back up it (with the
cutter deck down). If the machine can not back
up the slope without the wheels slipping, do not
operate the machine on this slope. Under no
circumstances should the machine be operated
on slopes greater than 15 degrees. See Figure 2-4
to determine approximate slope.
1. Check the full length of the seat belt webbing for
cuts, wear, fraying, dirt and stiffness. See Figure 2-3.
2. Check the seat belt webbing in areas exposed to
ultra violet rays from the sun or extreme dust or
dirt. If the original color of the webbing in these
areas is extremely faded and/or is packed with dirt,
the physical strength of this webbing may have
deteriorated. If this condition exists, replace the seat
belt system.
DO NOT mow near drop-offs, ditches or
embankments. The machine could suddenly roll
over if a wheel goes over the edge or if the edge
caves in.
3. Check the buckle and latch for proper operation
and determine if the latch plate is excessively worn,
deformed, or if the buckle is damaged or cracked.

4.4 STARTING THE ENGINE
Start practicing with a slow engine speed and slow
forward travel.
CAUTION
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a“runaway”engine condition
that could result in engine damage and/or
personal injury.
Learn to feather the steering controls to obtain a
smooth operating action.
Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.

1. Make sure the fuel valve is completely open on the
LP tank.
To travel forward with the mower, disengage the parking
brake, pull levers inward out of the neutral lock position
and slowly push the steering control levers forward an
equal distance. The further the steering control levers
are pushed forward the greater the forward speed will
be. To increase the speed, push the steering control
levers further forward and to decrease the speed, pull the
steering control levers back.
2. Secure the ROPS in the upright and locked position.
3. Sit in the operator’s seat, fasten seat belt and place
the steering control levers in the neutral position.
4. Engage the parking brake.
5. Place the PTO switch in the disengaged position.
6. If the engine is cold, choke the engine as needed.
To stop the forward travel, pull the steering control levers
back to the neutral position.
7. Move the engine throttle control to about half engine
speed.
To steer the mower left while traveling forward, pull the left
steering lever back. The further the lever is pulled back,
the quicker the mower will turn left.
8. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do
not hold the key in the START position for more
than 15 seconds at a time. Allow at least 60
seconds between each cranking attempt to prevent
overheating of the starter motor. Prolonged cranking
can damage the starter motor and shorten battery
life.
To steer the mower right while traveling forward, pull the
right steering control lever back. The further the lever is
pulled back, the quicker the mower will turn right.
- NOTe -
9. Allow engine to warm before operating the mower.
Smooth operation of the steering levers will
produce smooth mower operation. While learning
the operation of the steering controls, keep the
travel speed low.
4.5 GROUND TRAvEL AND STEERING
- IMPORTANT -
If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions.
- IMPORTANT -
Do not travel forward over a curb. The mower will
hang up on the curb. Raise the deck and travel
backwards over the curb at a 45 degree angle.

To travel in reverse, pull levers inward out of the neutral
lock position and pull both handles back. Keep the travel
speed low while traveling in reverse.
- NOTe -
A squealing noise may be heard when engaging
or disengaging the deck drive. It is caused by the
electric clutch plates meshing as the mower comes
up to speed. This is normal.
The mower may not travel straight in reverse.
Slight adjustments may need to be made using
the steering controls.
To steer left while traveling in reverse, allow the left
steering control lever to move forward. The further the
control is allowed to move forward, the quicker the mower
will turn left.
3. To disengage the deck drive, push the switch in to
the disengage position.
4. Always operate the engine at full throttle to properly
maintain cutting speed. If the engine starts to lug
down, reduce the forward speed and allow the
engine to operate at maximum RPM.
To steer right while traveling in reverse, allow the right
steering control lever to move forward. The further the
control is allowed to move forward, the quicker the mower
will turn right.
To stop the reverse travel, allow the steering control levers
to return to the neutral position. If the mower is to be
parked, place the handles in the neutral lock position and
engage the parking brake.

4.7 HILLSIDE OPERATION
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not
use high pressure spray or direct the spray onto
electrical components.
WARNING
- IMPORTANT -
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. Under no circumstances should the
machine be operated on slopes greater than 15
degrees. ALWAYS FOLLOW OSHA APPROvED
OPERATION.
Do not wash a hot or running engine. Cold water
will damage the engine. Use compressed air to
clean the engine if it is hot.
2. Keep the entire mower clean to inhibit serious heat
damage to the engine or hydraulic oil circuit.
3. Check the drive belts for proper alignment and any
signs of wear. Correct and adjust if necessary.
1. This mower has been designed for good traction
and stability under normal mowing conditions.
However, caution must be used when traveling on
slopes, especially when the grass is wet. Wet grass
reduces traction and steering control. The Roll-Over
Protection System is standard equipment for this
machine. See Section 2.5, page 6 of this manual for
further details.
DANGER
To avoid injury from burns, allow the mower to
cool before removing the LP tank.
2. To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel
at reduced speed. If tires loose traction, disengage
blades and proceed slowly off the slope.
4. See Engine Owner's Manual for proper liquid
propane requirements.
5. Check the tire pressure. Adjust pressure if
necessary.
3. Stay two cut widths away from slopes, drop offs,
ditches and retaining walls.
4.10 REMOvING CLOGGED MATERIAL
4. Avoid sudden starts when mowing uphill. Sudden
starts may cause the machine to tip backwards.
5. Loss of traction may occur when traveling down hill.
Weight transfers to the front of the machine and
may cause the drive wheels to slip causing loss of
braking or steering.
DANGER
ROTATING BLADES
6. Keep tires properly inflated.
NEvER PUTYOUR HANDS INTOTHE DISCHARGE
CHUTE FOR ANY REASON!
4.8 PARkING THE MOWER
1. Park the machine on a flat, level surface only. Do not
park the machine on an incline.
Shut off the engine and remove the key and
only then use a stick or similar object to remove
material if clogging has occurred.
2. Place the steering control levers in the neutral
position.
3. Disengage the cutter blades.
4. Slow the engine to idle speed.
5. Engage the parking brake.
1. If the discharge chute becomes clogged, shut off

4.11 MOvING MOWER WITH ENGINE
STOPPED
5. When mowing wet or tall grass, mow the grass twice.
Raise the mower to the highest setting for the first
pass and then make a second pass to the desired
height.
To “free-wheel” or move the mower around without the
engine running, rotate the dump valve levers counter-
clockwise. See Figure 4-4. Disengage the parking brake
and move the mower by hand. When the machine is in the
desired position, engage the parking brake and rotate the
levers clockwise until they stop. The dump valve levers
must be returned to the DRIVE position and torqued to
10 lb-ft to drive the mower.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at full throttle for best cutting.
Mowing with a lower RPM causes the mower to tear
the grass. The engine is designed to be operated at
full speed.
8. Use the alternate stripe pattern for best lawn
appearance. Vary the direction of the stripe each
time the grass is mowed to avoid wear patterns in
the grass.

6.7 ELECTRIC CLUTCH ADJUSTMENT
ADJUSTMENT NUTS
The electric clutch serves two functions in the operation of
the mower. In addition to starting and stopping the power
flow to the cutter blades, the clutch also acts as a brake to
assist in stopping blade rotation when the PTO is switched
off or the operator presence circuit is interrupted.
When the clutch is disengaged, the air gap between the
armature and rotor must be adjusted to fifteen thousandths
of an inch, 0.015, for proper operation. The airgap
adjustment is made at three bolts on the clutch.There are
three inspection windows, one next to each adjusting bolt.
See Figure 6-10.
INSPECTION WINDOW (x3)
ADJUSTMENT NUTS
Figure 6-12. Clutch Air Gap Adjustment
Figure 6-10. Clutch Air Gap Adjustment
This adjustment should be done every 500 hours of
operation or annually, whichever comes first. In cases
where the machine is heavily used, airgap settings should
be checked more often.
1. Locate the inspection windows on the clutch.
2. Place a 0.015 feeler gauge in the slot between the
rotor and the armature. See Figure 6-11.
If the air gap is too narrow, the clutch armature may drag
when disengaged, resulting in premature failure.
INSERT 0.015 FEELER GAUGE HERE
If the air gap is too wide, the clutch may be slow to engage
as the magnet must pull the armature in from a greater
distance.
Figure 6-11. Clutch Air Gap Adjustment
3. Tighten or loosen the adjusting bolt as needed to
acheive the 0.015 inch airgap. See Figure 6-12.
Perform this operation at all three inspection
windows.

Spindle assemblies have a Limited Warranty for three years (parts and labor 1st year and 2nd; parts only 3rd year).
Any Scag product used for rental purposes is covered by a 90 day warranty.
The Scag mower, including any defective part must be returned to an Authorized Scag Service Dealer within the warranty period. The
expense of delivering the mower to the dealer for warranty work and the expense of returning it to the owner after repair will be paid
for by the owner. Scag’s responsibility is limited to making the required repairs and no claim of breach of warranty shall be cause for
cancellation or rescission of the contract of sale of any Scag mower. “Non-Commercial” use is defined as a single property owner,
where the single property is the residence of the owner of the mower. If the mower is cutting more than the owners single property, it is
deemed commercial use and the “non-commercial” warranty does not apply. Scag Power Equipment reserves the right to deny and / or
void the non-commercial warranty if it believes it to be in commercial use.
This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has been
operated in any way contrary to the operating instructions as specified in the Operator’s Manual. The warranty does not apply
to any damage to the mower that is the result of improper maintenance, or to any mower or parts that have not been assembled or
installed as specified in the Operator’s Manual and Assembly Manual. The warranty does not cover any mower that has been altered or
modified, changing performance or durability. In addition, the warranty does not extend to repairs made necessary by normal wear, or
by the use of parts or accessories which, in the reasonable judgment of Scag, are either incompatible with the Scag mower or adversely
affect its operation, performance or durability.
Scag Power Equipment reserves the right to change or improve the design of any mower without assuming any obligation to
modify any mower previously manufactured. All other implied warranties are limited in duration to the two (2) year for commercial
use, three (3) years / 500 hour for non-commercial use or ninety (90) days for mowers used for rental purpose. Accordingly, any such
implied warranties including merchantability, fitness for a particular purpose, or otherwise, are disclaimed in their entirety after the
expiration of the appropriate two year or ninety day warranty period. Scag’s obligation under this warranty is strictly and exclusively
limited to the repair or replacement of defective parts and Scag does not assume or authorize anyone to assume for them any other
obligation. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for gasoline,
expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner, mechanic’s travel time,
telephone or telegram charges, rental of a like product during the time warranty repairs are being performed, travel, loss or damage to
personal property, loss of revenue, loss of use of the mower, loss of time or inconvenience. Some states do not allow the exclusion or
limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This warranty gives you
specific legal rights, and you may also have other rights which vary from state to state.
