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.
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.
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.
FOLDABLE ROLL-OvER PROTECTION SYSTEM
(IF EqUIPPED)
WARNING
Keep the roll bar in the raised and locked position
and the seat belt securely fastened during
operation. Failure to do so could cause serious
injury or loss of life.

SAFETY INTERLOCK SYSTEM4.2
The mower is equipped with a safety interlock system that
prevents the engine from starting unless the deck drive is
disengaged, the parking brake is engaged, the steering
control levers are in the neutral position and the operator
is in the seat. The interlock system shuts off the engine
if the operator leaves the seat with the steering control
levers not in the neutral position and/or the cutter blades
engaged and the parking brake not engaged.
WARNING
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.

comfortable with the controls before proceeding
to mow.
FORWARD TRAvEL
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.
To stop the forward travel, pull the steering control levers
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 quicker the mower will turn left.
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 -
Smooth operation of the steering levers will
produce smooth mower operation. While learning
the operation of the steering controls, keep the
travel speed low.
Allow engine to warm before operating the mower.
9.
GROUND TRAvEL AND STEERING4.5
- 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.
Learn the operation on flat ground before operating
on slopes.
Start practicing with a slow engine speed and slow
forward travel.
- 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.
(See Section 4.1, items 12 - 14, on page 14 for

HILLSIDE OPERATION4.7
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. ALWAYS FOLLOW OSHA APPROvED
OPERATION.
This mower has been designed for good traction 1.
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.
AFTER OPERATION4.9
Wash the entire mower after each use. Do not 1.
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.
Keep the entire mower clean to inhibit serious heat
2.
damage to the engine or hydraulic oil circuit.
Check the drive belts for proper alignment and any 3.
signs of wear. Correct and adjust if necessary.
DANGER
To avoid injury from burns, allow the mower
to cool before removing the fuel tank cap and
refueling.
To prevent tipping or loss of control, do not start or 2.
stop suddenly, avoid unnecessary turns and travel
at reduced speed. If tires loose traction, disengage
blades and proceed slowly off the slope.
Avoid sudden starts when mowing uphill. Sudden 3.
starts may cause the machine to tip backwards.
Loss of traction may occur when traveling down hill.
4.
Weight transfers to the front of the machine and
may cause the drive wheels to slip causing loss of
braking or steering.
5.
Keep tires properly inflated.
PARKING THE MOWER4.8
Park the machine on a flat, level surface only. Do not 1.
park the machine on an incline.
Place the steering control levers in the neutral

Raise the mower to the highest setting for the first
pass and then make a second pass to the desired
height.
Use a slow travel speed for trimming purposes.6.
Operate the engine at full throttle for best cutting. 7.
Mowing with a lower RPM causes the mower to tear
the grass. The engine is designed to be operated at
full speed.
Use the alternate stripe pattern for best lawn 8.
appearance. Vary the direction of the stripe each
time the grass is mowed to avoid wear patterns in
the grass.
ADJUSTING CUTTING HEIGHT4.13
The mower deck can be adjusted from a height of 1-1/2
inches to 5-1/2 inches at 1/4-inch intervals. To adjust the
cutting height:
DO NOT operate without Discharge Chute,
Mulching Kit, or entire Grass Catcher properly
installed.
Dump Valve ControlFigure 4-4.
RECOMMENDATIONS FOR MOWING4.12
Do not mow with dull blades. A dull blade will tear 1.
grass, resulting in poor lawn appearance and
reduced mowing power.
WARNING
The discharge chute must not be removed and 2.
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.

models), or seven (7) (current production) different
positions for optimum performance.
3-POSITION CUSTOM-CUT BAFFLE
ADJUSTMENT - EARLY MODELS
A. 3" Position - (See Figure 6-8). Baffle is installed
using the top set of holes on the front baffle welded
inside the cutter deck. In this position the Velocity-Plus
cutter deck will deliver the best quality-of-cut in very
tall, wiry, tough to cut grass.
To adjust the Custom-Cut Baffle height:
1.
Place the cutter deck in the transport position.
Remove the hardware securing the Custom-Cut 2.
Baffle to the cutter deck. See Figure 6-8.
- NOTe -
Hardware location used in the illustrations are for
reference only. Location of hardware may vary
depending on cutter deck size.
Move the Custom-Cut Baffle to desired position. See

Reinstall the mounting hardware as shown. Torque
hardware to 39 lb-ft.
7-POSITION CUSTOM-CUT BAFFLE
ADJUSTMENT - CURRENT PRODUCTION
A. 3-1/2" or 3-3/4" Position - (See Figure 6-9). For very
tall, wiry or tough-to-cut grass.
B. 4" (factory setting), 4-1/4" or 4-1/2" Position - (See
Figure 6-9). For general purpose cutting. This gives the
best mix of cutting performance in all types of grass.
C. 4-3/4" or 5-1/4" Position - (See Figure 6-9). Placing
the baffle in either the 4-3/4" or 5-1/4" setting will
enhance fall cutting (leaf pickup) and reduce cutter
deck "blowout".
To adjust the Custom-Cut Baffle height:
B. 3-1/2" Position - (See Figure 6-8). Baffle is installed
using the middle set of holes on the front baffle welded
inside the cutter deck. Can be used for general purpose
cutting. Placing the Custom-Cut Baffle in the 3-1/2"
position gives a good mix of cutting performance in all
types of grass.
C. 4" Position (factory setting) - (See Figure 6-8). Baffle
is installed using the bottom set of holes on the front
baffle welded inside the cutter deck. Placing the baffle
in the 4" setting will enhance fall cutting (leaf pickup)
and reduce cutter deck "blowout".

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 6-3.
Section 6
Clutch Air Gap AdjustmentFigure 6-1.
Locate the inspection windows on the clutch.1.
Place a 0.015 feeler gauge in the slot between the 2.
rotor and the armature.
Tighten or loosen the adjusting bolt as needed to 3.
acheive the 0.015 inch airgap. See Figure 6-4.
Perform this operation at all three inspection
windows.
Clutch Air Gap AdjustmentFigure 6-1.
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.
If the air gap is too narrow, the clutch armature may drag
when disengaged, resulting in premature failure.
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.

WARNING
Lead-acid batteries produce flammable and
explosive gases. To avoid personal injury when
checking, testing or charging batteries, DO NOT
use smoking materials near batteries. Keep arcs,
sparks and flames away from batteries. Provide
proper ventilation and wear safety glasses.
WARNING
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to cause cancer and reproductive harm.
Wash hands after handling.
A. CHARGING THE BATTERY
Refer to the battery charger’s manual for specific
instructions.
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.
WARNING
Electric storage battery fluid contains sulfuric
acid which is POISON and can cause SEvERE
CHEMICAL BURNS. Avoid contact of fluid with
eyes, skin, or clothing. Use proper protective gear
when handling batteries. DO NOT tip any battery
beyond 45° angle in any direction. If fluid contact
does occur, follow first aid suggestions below.
BATTERY ELECTROLYTE FIRST AID
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.
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.
B. JUMP STARTING
The booster battery must be a 12 volt type. If a 1.
vehicle is used for jump starting, it must have a

CUTTER BLADES7.9
A. BLADE INSPECTION
Remove the ignition key before servicing the blades.1.
Raise the mower deck to the highest position. Place 2.
the lanyard pin in the highest cutting height position
to prevent the cutter deck from falling.
B. BLADE SHARPENING
- NOTe -
If possible, use a file to sharpen the blade. Using
a wheel grinder may burn the blade.
- NOTe -
DO NOT sharpen the blades beyond 1/3 of the
width of the blade. See Figure 7-6.
1.
Sharpen the cutting edge at the same bevel as the
original. See Figure 7-6. Sharpen only the top of the
cutting edge to maintain sharpness.
4.
WARNING
Always wear proper hand and eye protection when
working with cutter blades.
Check the cutter blades for straightness. If the cutter 3.
blades appear bent, they will need to be replaced.
WARNING
Do not attempt to straighten a bent blade, and
never weld a broken or cracked blade. Always
replace it with a new blade to assure safety.
If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
- NOTe -
Keep the blades sharp. Cutting with dull blades not
only yields a poor mowing job, but slows the cutting
speed of the mower and causes extra wear on the
engine and the blade drive by pulling hard.
Blade SharpeningFigure 7-6.
Check the balance of the blade. If the blades are out 2.
of balance, vibration and premature wear can occur.
See your authorized Scag dealer for blade balancing

Esta garantía no cubre ningún cortacésped que haya sido sometido a uso indebido, descuido, negligencia o accidente, o que
se haya operado de manera distinta a la especificada en el manual del operador . La garantía no será de aplicación en ningún caso
de daño ocasionado al cortacésped como consecuencia de mantenimiento inadecuado o a cualquier cortacésped o piezas que no se hayan

mecánico, cargos por comunicaciones telefónicas o telegramas, alquiler de un producto similar durante el período en que se llevan a cabo
las reparaciones bajo garantía, viajes, pérdida o daño de bienes personales, lucro
cesante, daños ocasionados por la pérdida del uso
del cortacésped, daños por la pérdida de tiempo o cualquier otro inconveniente. La limitación o exclusión antes
mencionada no será de aplicación en aquellos estados en los que no esté permitida la exclusión o limitación de daños
