that prevents the engine from starting unless the deck
drive is disengaged and the speed control is in neutral and
the parking brake is engaged. The interlock system shuts
off the engine if the operator leaves the seat with the
speed control in the neutral position and the parking
brake is not engaged and/or the cutter blades are
engaged. It will also shut the engine off if the cutter
deck drive is engaged and the hopper is raised.
11
WARNING:
Section 4
3. If the engine is cold, adjust the engine choke as
needed.
Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to yourself
and others or property damage could result.
4.3 INITIAL RUN-IN PROCEDURES (First
Day of Use or Approximately 10 Hours)
1. Check all belts for proper alignment and wear after
the initial 2, 4, and 8 hours of operation. The belt
systems are self adjusting therefore tension
adjustment is not necessary.
2. Change the engine oil and oil filter after the first 5
hours of operation. (See Section 7.4.)
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. Inflate tires if necessary.
4. Adjust engine throttle control to about half engine
speed.
5. 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.
6. 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.
4.4 STARTING THE ENGINE
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 on top of the
left fuel tank, is completely open. (See Section 7.4)
2. Sit in the operator’s seat and place the speed control
in the neutral position and engage the parking brake.
-IMPORTANT-
Start practice with a slow engine speed and slow
forward travel.
Do not push the steering control levers forward
when traveling forward. They are only used to
steer the mower and to travel in reverse by pulling
back on the levers.
Learn to operate the mower with the left hand on
the steering levers and the right hand on speed
control as shown in Figur e 4-4. Using both hands
on the steering levers often causes overcontrol.
Learn to feather the steering controls to obtain a
smooth operating action. Jerky movements tend
to place extreme force on the drive pumps and
axles, as well as damage the lawns.
Practice operating the mower until you can make
it go exactly where you are aiming.
12
Section 4
In case of an emergency, such as loss of control,
stop the mower’ s movement by quickly pulling the
forward speed contr ol lever to the neutral position.
Forward T ravel
-NOTE-
Use one hand on both steering levers as shown in
Figure 4-4 to minimize overcontrol.
T o travel forward with the mower , move the speed control
lever forward. Do not push the steering control levers
forward as they are used only for steering the mower left
or right. When the speed control is moved forward, the
mower will travel forward at the speed the control lever is
set at. T o increase the speed, push the control lever forward
and to decrease the speed, pull the control lever back. It is
not necessary to hold the speed control in position, since a
friction system holds the lever in position.
To stop the forward travel, pull the speed control lever
back to the neutral position.
To steer the mower left while traveling forward, pull the
left steering lever back. The further the lever is pulled
back, the sharper the mower will turn left.
T o steer the mower right while traveling forward, pull the
right steering control lever back. The further the lever is
pulled back, the sharper the mower will turn right.
-NOTE-
Smooth operation of the steering levers will
produce a 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
will hang up on the curb. Tilt the deck and
travel backwards over the curb at a 45 degree
angle. (See section 4.15 for cutter deck tilting
instructions)

Do not mow in reverse unless absolutely necessary
and then only after observation of the entire area
behind the mower .
To travel in reverse, pull both handles all the way back.
Keep the travel speed low while traveling in reverse.
-NOTE-
The mower will not travel straight in reverse.
Slight adjustments must be made using the
steering controls.

Section 4
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 sharper the
mower will turn left.
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 sharper the
mower will turn right.
To stop the reverse travel, place the speed control lever
in the neutral position and allow the steering control
levers to return to the neutral position. If the mower is
to be parked, engage the parking brake and remove the
ignition key.
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 — use only
moderate engine speed when engaging the deck
drive.
2. Engage the deck drive by pushing the Cutter Deck
Control Lever forward, (Figure 4-6) to the engage
position.
Cutter Deck
Control Lever
3. T o disengage the deck drive, pull back the Cutter
Deck Control Lever to the disengage position.
4. Always operate the engine at full throttle to properly
maintain cutting performance. 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:
T o minimize the possibility of overturning, the least
dangerous method of operating on hills and
terraces is to travel vertically up and down the slope,
not horizontally along the slope. Avoid any
unnecessary turns and travel at reduced speed.
1. The 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.
2. To inhibit tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed.
3. Keep tires properly inflated.
SCR 2001MCD

4. Fill the fuel tank with fresh, clean fuel at the end of
every day of operation.
5. Check the tire pressure. Inflate tires if necessary.
4.10 HOPPER, MULCH or SIDE DISCHARGE
OPERATION
When mowing with the cutting deck setup for rear discharge
into the hopper (Figure 4-9), the blower belt must be installed.
A control lever located on the left side of the tractor (Figure
4-8) will release tension on the idler pulley to allow the belt
to be installed (grass catching operation) or removed
(mulching or side discharge operations). The cutter deck
must also be adapted to the type of cutting that the operator
is attempting to perform.
1. Place the speed control in the neutral position.
2. Slow the engine to idle speed.
3. Engage the parking brake.
4. 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.
-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.

Grass Catching Operation
CAUTION:
Never leave grass clippings in the hopper after
mowing. Wet or damp clippings will generate heat
as they decompose which may cause spontaneous
combustion to occur .
1. With the hopper lowered, engage the deck drive. When
the deck drive is engaged, the grass delivery spout,
which is designed to distribute the grass clippings
through the inside of the hopper, will begin to oscillate.
-NOTE-
The mower has an interlock switch that will

4.13 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. A dull blade will tear
grass, resulting in poor lawn appearance and
requiring extra power.
2. 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.
4.14 ADJUSTING CUTTING HEIGHT
The mower deck can be adjusted from a height of 1 1/2inches to 5-inches at 1/2-inch intervals. T o adjust the cutting
height:
WARNING:
Do not adjust the cutting height with the mower
blades rotating. Shut off the engine and remove
the ignition key . Bodil y injury could occur from the
rotating blades.
1. Shut off the engine and remove the ignition key.
Remove
Hair Pins
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. Keep mower and discharge system 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 or near 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.

7.7 BATTERY
A. Checking Electrolyte Level and Cleaning
Battery
After every 40 hours of operation or weekly, whichever
occurs first, check the electrolyte level in the battery and
clean the battery and connections. Dirt and fluid on the
top of the battery can cause the battery to discharge.
Corrosion of the battery terminals or loose connections
will cause poor battery performance.
WARNING:
Lead-acid batteries produce flammable and
explosive gases. T o avoid per sonal injury when
checking, testing or charging batteries, DO
NOT use smoking materials near batteries.
Keep arcs, sparks and flames away from
batteries. Pro vide proper ventilation and wear
safety glasses.
For any air cleaner, the operating environment dictates
the air cleaner service periods. Inspect and clean the air
cleaner element after every 100 hours of operation or biweekly, whichever occurs first and replace the element if
required.
-NOTE-
In extremely dusty conditions it may be necessary to check the element once or twice daily to
prevent engine damage.
1. Remove the wing nut securing the air cleaner cover
to the engine. Remove the air cleaner cover and set
aside.
2. Remove the nut securing the clamping plate and the
air cleaner to the engine. Remove the clamping plate

WARNING:
BATTERY ELECTROLYTE FIRST AID
Section 7
B. Charging the Battery
Refer to the battery charger’s manual for specific
instructions.
EXTERNAL CONTACT — Flush with water.
EYES — Flush with water for at least 15
minutes and get medical attention
immediately.
INTERNAL — Drink large quantities of water.
Follow with Milk Of Magnesia, beaten egg,
or vegetable oil. Get medical attention
immediately. In case of internal contact, DO
NOT give fluids that would induce vomiting.
1. Tilt the seat forward to access the battery.
2. Remove the battery cell caps. Visually inspect
electrolyte level in the cells. If electrolyte is
below the bottom of vent well, fill with clean distilled
water to the bottom of vent wells (1/4 to 1/2 inch
above the plates). Install the battery cell caps.
Under normal conditions the engine’s alternator will have
no problem keeping a charge on the battery. If the
battery has been completely discharged for a long period
of time, the alternator may not be able to recharge the
battery, and a battery charger will be required.
DO NOT charge a frozen battery. It may explode and
cause injury. Let the battery warm before attaching a
charger.
Whenever possible, remove the battery from the mower
before charging and make sure the electrolyte covers the
plates in all cells.
WARNING:
BATTERIES PRODUCE EXPLOSIVE
GASES. Charge the battery in a well
ventilated space so gases produced
while charging can dissipate.
-IMPORTANT-
Do not overfill the battery. Electrolyte will
overflow through the vent tube onto parts of
the machine, resulting in severe corrosion.
3. Clean the cable ends and battery posts with steel
wool or a wire brush. Use a solution of baking soda
and water to clean the battery. Do not allow the
solution to enter the battery cells.
4. Tighten the cable connections securely and apply a
light coat of silicone dielectric grease to the terminal
connections to prevent corrosion.
Charging rates between 3 and 50 amperes are
satisfactory if excessive gassing or spewing of
electrolyte does not occur or the battery does not feel
excessively hot (over 125°F). If spewing or gassing
occurs or the temperature exceeds 125°F, the charging
rate must be reduced or temporarily stopped to permit
cooling.
C. Jump Starting
1. The booster battery must be a 12 volt type. If a
vehicle is used for jump starting, it must have a
negative ground system.
2. When connecting the jumper cables, connect the
positive cable to the positive battery post, then
connect the negative cable to the negative battery
post.

after repair will be paid for by the owner. Scags 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.
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 Operators 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

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
warranty period 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. Scags 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.

gasoline, expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner,
mechanics 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.
