3. Check hydraulic oil level in reservoir. (See Section
7.3)
4. Check for loose hardware. Tighten as needed.
5. Check interlock system for proper operation. (See
Section 4.2)
6. Check tire pressure. Adjust pressure if necessary.
(See Section 7.10)
4.4 STARTING THE ENGINE
6. Turn the ignition key to the ST AR T position and
release the key as soon as the engine starts. Do not
hold the key in the ST ART 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.
7. Allow engine to warm before operating the mower.
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. 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. Be sure the fuel shutoff valve, located behind the
operator's seat by the left fuel tank, is completely
open. (See Section 7.5)
2. Sit in the operator’s seat and place the steering
control levers in the neutral position.
3. Engage the parking brake.
4. If the engine is cold, choke the engine as needed.
5. Move the engine throttle control to about half engine
speed.
-IMPORTANT-
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.
13
Section 4
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 13 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.
PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE
STT99CES
Figure 4-3 Cutter Engage Switch

Section 4
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.
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. ALWAYS FOLLOW OSHA APPROVED
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.
-IMPORTANT-
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. An optional Roll Over
Protection System is available for this machine. See
Section 2.5, page 6 of this manual for further details.
2. To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed.
3. Keep tires properly inflated.
4.8 PARKING THE MOWER
1. Place the steering control levers in the neutral
position.
2. Disengage the cutter blades
T o avoid injury from b urns, allo w the mower to cool
before removing the fuel tank cap and refueling.
4. After the mower has cooled down, fill the fuel tanks
with fresh, clean fuel at the end of every day of
operation. See Engine Owner's Manual for proper
octain requirements.
5. Check the tire pressure. Adjust pressure if necessary.
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.
3. Slow the engine to idle speed.
4. Engage the parking brake.
5. Turn the ignition key to the OFF position and remove
the key.
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.
15
Section 4
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
FREE-WHEEL position (Figure 4-2, Page 1 1).
Disengage the parking brake and move the mower by
hand. The dump valve levers must be returned to the
DRIVE position and torqued to 10ftlbs to drive the
mower.
4.12 RECOMMENDATIONS FOR MO WING
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and require
more engine 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.
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.
4.13 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1-inch
to 5-1/2 inches at 1/4-inch intervals. T o adjust the cutting
height:
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 4-5)
3. Insert the lanyard 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. (Figure 4-5)
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 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.

all moving parts to come to a complete stop
before beginning work.
CAUTION:
The engine and drive unit can get hot during
operation causing burn injuries. Allow engine
and drive components to cool before making any
adjustments.
-NOTE-
Before proceeding with this adjustment, be sure
that the caster wheels turn freely and that the tire
pressure in the drive wheels is correct. If the tire
pressure is not correct, the machine will pull to
the side with the lower pressure.
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock
nuts securing the ball joints at each end of the
RH steering control rod. Rotate the control rod
to shorten the rod and tighten the lock nuts.
This will cause the control rod to stroke the RH
pump less, slowing down the RH wheel. (See
Figure 6-3).
-NOTE-
If after making the adjustment as outlined in step
2A, the machine creeps forward or backward, the
neutral adjustment must be made as described on

follows:
A. Stop the machine and place the steering control
levers in the neutral position. Loosen the lock
nuts securing the ball joints at each end of the
LH steering control rod. Rotate the control rod
to shorten the rod and tighten the lock nuts.
This will cause the control rod to stroke the LH
pump less, slowing down the LH wheel. (See
Figure 6-3).
-NOTE-
If after making the adjustment as outlined in step
1A, the machine creeps forward or backward, the
neutral adjustment must be made as described on
page 22.
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:
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.
6.5 BELT ALIGNMENT
Belt alignment is important for proper performance of
your Scag mower. If you experience frequent belt wear
or breakage, see your authorized Scag service center for
belt adjustment.

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:
1. On the front LH side of the cutter deck locate the
cutter deck adjusting bolt. (See Figure 6-4)
2. Loosen the elastic stop nut and move the bolt up or
down in the slot to adjust the cutter deck until the
distance from the top of the cutter deck to the floor
is the same as the measurement on the RH side of
the machine.
3. Tighten the elastic stop nut to secure the cutter deck
in the proper position.
Cutter Deck Pitch
The pitch of the cutter deck should be level from front to
back 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 equal with 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 level, the cutter deck pitch must be
adjusted as follows:
1. Loosen the lock nuts on both adjusting rods.
(See Figure 6-4)
CUTTER DECK
LOCK NUT
ADJUSTING BOLT
STC2001CDA
Figure 6-4. Cutter Deck Adjustment
2. Using an adjustable jaw pliers, turn the adjusting rods
on the non threaded portion of the rod until the deck
is equal front to back on both the RH and the LH
side of the cutter deck. Tighten both lock nuts.
-NOTE-
To prevent the cutter deck from teetering, all four
cutter deck hanging chains must have tension on
them. If all four chains do not have tension on
them and the deck teeters, you must readjust the
cutter deck as outlined in the procedures above.
All measurements should be taken from the top
edge of the deck as the Advantage+ decks have
an uneven bottom edge.
24
Section 6
Cutter Deck Height
The cutter deck height adjustment is made to ensure that
the cutter deck is cutting at the height indicated on the
cutting height index gauge. To check for proper deck
height, be sure that the mower is on a flat, level surface
and the tires are properly inflated.
1. Place the cutter deck in the transport position.
Loosen the jam nuts on both ends of the deck height
control rod. (See Figure 6-5)

3. Check the cutter deck cutting height by placing the
lanyard pin in the 3" position on the cutting height
index. Release the deck from the transport positon
and allow the deck to move to the 3" cutting height
position.
4. Check the measurement from the floor to the cutter
blade tip. If the measurement is not at 3", an
adjustment can be made using the deck height
control rod. (See Figure 6-5)
-NOTE-
If an adjustment had to be made, be sure that the
cutter deck can easily be locked into the
transport position.
Custom-Cut Baffle Adjustment
The Custom-Cut Baffle is designed to deliver optimum
airflow and superior cutting performance in any type of
grass. The Custom-Cut Baffle can be raised or lowered
to precisely tailor the deck's performance for the type of
grass being cut. The baffle can be set in three (3)
different positions for optimum performance.
