WARNING:
FAILURE TO FOLLOW SAFE OPERATING PRACTICES
MAY RESULT IN SERIOUS INJURY.
* Read this manual completely as well as other manuals that came
with your mower.
* 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 mow on wet grass. Wet grass reduces traction and steering
control.
* Keep all shields in place, especially the grass discharge chute.
* Before performing any maintenance or service, stop the machine and
remove the spark plug wire and ignition key.
* If a mechanism becomes clogged, stop the engine before cleaning.
* Keep hands, feet and clothing away from power-driven parts.
* Keep others off the tractor (only one person at a time)
REMEMBER - YOUR MOWER IS ONLY AS SAFE AS THE OPERATOR!
Hazard control and accident prevention are dependent upon the awareness,
concern, prudence, and proper training of the personnel involved in the
operation, transport, maintenance, and storage of the equipment.

Section 2
2.5 ROLL-OVER PROTECTION SYSTEM
WARNING:
Seat belt must be securely fastened during
operation. Failure to do so could cause
serious injury or loss of life.
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. Do not mow on wet grass. W et grass reduces traction
and steering control.
Any or all parts of the Roll-Over Protection System MUST
NOT be removed. Failure to adhere to this guideline could
result in injury or death.
The potential exposure of this seat belt to severe enviromental
conditions make it crucial to inspect the seat belt system
regularly .
It is recommended that the seat belt be inspected on a daily
basis for signs of damage. Any seat belt system that shows
cuts, fraying, extreme or unusual wear, significant
discoloration due to UV exposure, dirt or stiffness, abrasion
to the seat belt webbing, or damage to the buckle, latch
plate, hardware or any other obvious problem should be
replaced immediately .
3. Check the buckle and latch for proper operation and
determine if the latch plate is exessively worn, deformed,
or if the buckle is damaged or cracked. See Figure 2-1.
INSPECT BUCKLE
& LATCH
INSPECT WEBBING
Figure 2-1 Seat Belt Inspection
WARNING:
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.
ALWAYS travel up or down the slope whenever
possible. Never across the slope.
WARNING:
Failure to properly inspect and maintain the
seat belt can cause serious injury or loss of
life.
1. Check the full length of the seat belt webbing for cuts,
wear, fraying, dirt and stif fness. See Figure 2-1.
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.
Operate the machine smoothly, no sudden turns,
starts or stops on a slope.
NEVER tow on slopes. The weight of the towed
equipment may cause loss of traction and loss of
control.
DO NOT permit untrained personnel to operate the
machine.

starter motor. Prolonged cranking can damage the
starter motor and shorten battery life.
6. Allow engine to warm before operating the mower.
4.5 GROUND TRA VEL AND STEERING
-IMPORT ANT-
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. Practice
until you are comfortable with the handling of
the machine before attempting to mow. Learn
the operation on flat ground before operating
on slopes.
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.
1. Sit in the operator’s seat, fasten seat belt and place
the steering control levers in the neutral position.
2. Engage the parking brake.
3. If the engine is cold, choke the engine as needed.
4. Move the engine throttle control to about half engine
speed.
-IMPORT ANT-
Start practicing with a slow engine speed and
slow forward travel. Learn to feather the
steering controls to obtain a smooth
operating action.
Forward T ravel
T o 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.
T o stop the forward travel, pull the steering control levers
back to the neutral position.
T o 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.
14
Section 4
STT99CES
PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE
T o 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-
Smooth operation of the steering levers will
produce smooth mower operation. While
learning the operation of the steering
controls, keep the travel speed low.
-IMPORTANT-
Do not travel forward over a curb. The
mower may hang up on the curb. Raise the
deck and travel backwards over the curb at a
45 degree angle. (see Section 4.1, item 12 for
cutter deck raising instructions)
Reverse Travel
CAUTION:
Disengage power to the mower before backing up.
Do not mow in reverse unless absolutely necessary
and then only after observation of the entire area
behind the mower .
CAUTION:
T o 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.
T o 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.
4.6 ENGAGING THE DECK DRIVE (CUTTER
BLADES)
1. Set the throttle at about 3/4 speed. Do not attempt to
engage the deck drive at high speed as this shortens
the electric clutch life — use only moderate engine
speed when engaging the deck drive.
2. Engage the deck drive by pulling out on the yellow
switch, located on the instrument panel, (Figure 4-3)
to the engage position.
-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.
Before backing up, obser ve the rear for persons
and obstructions. Clear the area before backing
up. P ossible injury or property damage could occur.
T o 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-
The mower may not travel straight in reverse.
Slight adjustments must be made using the
steering controls.
T o 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.
Figure 4-3 Cutter Engage Switch

Section 4
3. T o 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.
4.7 HILLSIDE OPERATION
WARNING:
DO NOT operate on steep slopes. T o 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.
4.8 PARKING THE MOWER
1. Park the machine on a flat, level surface only . Do not
park the machine on an incline.
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.
6. Turn the ignition key to the OFF position and remove
the key.
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.
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 7 of this manual for
further details.
2. T o prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed. If tires lose traction, disengage
blades and proceed slowly off the slope.
3. A void sudden starts when mowing uphill. Sudden
starts may cause the machine to tip backwards.
4. 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.
-IMPORT ANT-
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.
4. Check the tire pressure. Adjust pressure if necessary.
5. Keep tires properly inflated.
16
Section 4
WARNING
4.10 REMOVING CLOGGED MATERIAL
ROTATING BLADES
NEVER PUT Y OUR HANDS INT O THE DISCHARGE
CHUTE FOR ANY REASON! Shut off the engine and
remove the key and only then use a stick or similar
object to remove material if clogging has occurred.
1. If the discharge chute becomes clogged, shut off the
engine and remove the ignition key . Using a stick or
similar item, dislodge the clogged material. Then
resume normal mowing.
4.11 MOVING MOWER WITH ENGINE
STOPPED
To “free-wheel” or move the mower around without the
engine running, place the dump valve levers in the FREEWHEEL position (Figure 4-2, page 13). Disengage the
parking brake and move the mower by hand. The dump
valve levers must be returned to the DRIVE position to
drive the mower.
4. Keep mower and discharge chute clean.
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.
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 an 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.
4.13 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1- inch
to 4-1/2 inches at 1/4-inch intervals. T o adjust the cutting
height:
4.12 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and require
extra power.
2. The discharge chute must not be removed and must
be kept in the lowest position to deflect grass
clippings and thrown objects downward. Direct the
side discharge away from sidewalks or streets to
minimize cleanup of clippings. When mowing close
to obstacles, direct the discharge away from the
obstacles to reduce the chance of property damage
by thrown objects.
WARNING
DO NOT OPERATE WITHOUT DISCHARGE CHUTE, MULCHING
KIT, OR ENTIRE GRASS CATCHER INSTALLED
3. Cut grass when it is dry and not too tall. Do not cut
grass too short (cut off 1/3 or less of existing grass
for best appearance). Mow frequently.
WARNING:
DO NOT adjust the cutting height with the mower
blades rotating. Disengage the power to the cutter
blades and then adjust cutting height.
1. Disengage the power to the cutter blades.
2. Push the cutting height adjustment foot pedal all the
way forward using your right foot until it locks in
place. (Figure 4-4, page 18)
3. Insert the pin into the cutting height index at the
desired cutting height. Push forward on the deck lift
foot lever, hold in place and lift up on the deck release
lever, (Figure 4-4). Slowly release the foot pedal. A
deck height decal is located on the cutting height index
as an aid in adjusting the deck to the desired height.

-NOTE-
If after making the adjustments as outlined do not
correct the tracking or neutral, contact your local
Authorized Scag Power Equipment Dealer.
6.3 THROTTLE CONTROL AND CHOKE
ADJUSTMENTS
These adjustments must be performed by your Scag
dealer to ensure proper and efficient running of the
engine. Should either need adjustment, contact your
authorized Scag service center.
6.4 BELT ADJUSTMENT
WARNING:
Before removing any guards, shut the
engine off and remove the ignition key.
All drive belts and cutter deck belts are spring loaded and
self-tensioning. The belts should be checked periodically
for proper alignment and wear.
1. If at full speed the mower pulls right, it is an
indication that the left wheel is turning faster than the
right wheel. T o adjust this condition, proceed as
follows:
A. Stop the machine and place the steering control
levers in the neutral position. Turn the tracking
adjustment bolt for the LH pump inward
(clockwise). This will cause the control rod to
stroke the LH pump less, slowing down the LH
wheel. (See Figure 6-3, Page 23).
2. If at full speed the mower pulls left, it is an indication
that the right wheel is turning faster than the left
wheel. T o adjust this condition, proceed as follows:
A. Stop the machine and place the steering control
levers in the neutral position. Turn the tracking
adjustment bolt for the RH pump inward
(clockwise). This will cause the control rod to
stroke the RH pump less, slowing down the RH
wheel. (See Figure 6-3).
6.5 BELT ALIGNMENT

Section 6
6.6 CUTTER DECK ADJUSTMENTS
Cutter deck level, pitch and height are set at the factory.
However, if these adjustments should ever need to be
made, the following procedures will aid in obtaining the
proper cutter deck adjustment.
-NOTE-
Before proceeding with the cutter deck
adjustments, be sure that all tires are properly
inflated.
Cutter Deck Level
The cutter deck should be level from side-to-side for
proper cutting performance. To check for level, be sure
that the mower is on a flat, level surface, the tires are
properly inflated and the cutter deck is set at the most
common cutting height that you will use. On the RH side
of the machine, check the distance from the top of the
cutter deck to the floor. Next check the distance from
the top of the cutter deck to the floor on the LH side of
the machine. Both measurements should be the same.
If the two measurements are different, the cutter deck
level must be adjusted as follows:
3. Tighten the two elastic stop nuts to secure the cutter
deck in the proper position.
Cutter Deck Pitch
The pitch of the cutter deck should be equal between the
front and rear of the cutter deck for proper cutting
performance. To check for proper deck pitch, be sure
that the mower is on a flat, level surface and the tires are
properly inflated.
Check the distance from the top of the cutter deck to the
floor at the rear RH side of the cutter deck directly
behind the cutter deck hanging chains. Next check the
distance from the top of the cutter deck to the floor at
the front RH side of the cutter deck directly in front of
the cutter deck hanging chains. The measurement at the
front of the cutter deck should be the same as the rear of
the deck. Make these measurements at the LH side of
the cutter deck also. If the measurement at the front of
the deck is not the same, the cutter deck pitch must be
adjusted as follows:
1. Loosen the elastic stop nuts securing the deck level
links on front of the cutter deck on both sides (See
Figure 6-5, Figure 6-6).
1. If the cutter deck is lower on one side, loosen the
elastic stop nuts securing the deck level links on the
front and rear of the lower side. (See Figure 6-4).
