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, is completely open. (See section 7.5.)
2. Sit in the operators seat and place the steering
control levers in the neutral position.
3. Engage the parking brake.
4. Place the PTO switch in the disengaged position.
5. If the engine is cold, choke the engine as needed.
6. 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.
Practice operating the mower until you are
comfortable with the controls before proceeding
to mow.
Forward Travel
To travel forward with the mower, disengage the parking
brake 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.
12
Section 4
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.
-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 4.13 for cutter deck
raising instructions)
Reverse Travel
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.
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, 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.
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:
Before backing up, observe the rear for persons and
obstructions. Clear the area before backing up.
Possible injury or property damage could occur.
To travel in reverse, pull both handles back. Keep the
travel speed low while traveling in reverse.
-NOTE-
The mower may not travel straight in reverse.
Slight adjustments may need to be made using
the steering controls.

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.
T o avoid injury from burns, allow the mower to cool
before removing the fuel tank cap and refueling.
2. To prevent tipping or loss of control, start and stop
smoothly, avoid unnecessary turns and travel at
reduced speed.
3. Keep tires properly inflated.
4.8 P ARKING THE MOWER
1. Place the steering control levers in the neutral
position.
2. Disengage the cutter blades
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.
4. After the mower has cooled down, fill the fuel tank
with fresh, clean fuel at the end of every day of
operation.
5. Check the tire pressure. Adjust pressure if
necessary.

4.10 REMOVING CLOGGED MA TERIAL
ROTATING BLADES
NEVER PUT YOUR HANDS INTO 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). 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.
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.
DUMP VALVE
CONTROL
4.12 RECOMMENDA TIONS 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.
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 chute clean.

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 bottom of
the cutter deck to the floor. Next check the distance
from the bottom 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 elastic stop nut to secure the cutter deck
in the proper position.
Cutter Deck Pitch
The pitch of the cutter deck should be 1/4" down toward
the front 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. Use the following procedures,
however, measure from the top of the cutter deck rather
than the bottom edge. Lay a straight edged object on the
top of the Advantage cutter deck, protruding towards the
front of the machine, when measuring the front height.
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 1/4" lower than the
measurement at 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 1/4"
lower, the cutter deck pitch must be adjusted as follows:
1. On the front LH side of the cutter deck locate the
cutter deck adjusting bolt. (See Figure 6.5)
JAM NUT

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 bottom of the cutter deck to the
floor is the same as the measurement on the RH side
of the machine.
1. Loosen the jam nuts on both adjusting rods.
(See Figure 6-5)
2. Using a wrench on the spring compression nut (See
Figure 6-5) turn the adjusting rods until the 1/4"
forward pitch is obtained on both the RH and the LH
side of the cutter deck. Tighten both jam 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.

31
Section 7
WARNING:
BATTERIES PRODUCE EXPLOSIVE
GASES. Charge the battery in a well
ventilated space so gases produced while
charging can dissipate.
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.
WARNING:
Always wear proper hand and eye protection
when working with cutter blades.
3. Check the cutter blades for straightness. If the
cutter 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.
4. 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.
7.8 DRIVE BELTS
All drive belts are spring loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and
wear. Thereafter, check the belts after every 40 hours
of operation or weekly, whichever occurs first.
-NOTE-
If you experience frequent belt wear or breakage,
see your authorized Scag service center for belt
adjustment.
7.9 CUTTER BLADES
A. Blade Inspection
1. Remove the ignition key before servicing the blades.
2. Raise the mower deck to the highest position. Place
the lanyard pin in the highest cutting height positon 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 7-9, Page 33.

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 one (1) 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 one 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.
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,
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.
