4.2 SAFETY INTERLOCK SYSTEM

This mower is equipped with a safety system that prevents
the engine from starting unless the mower blade brake is
disengaged and parking brake is engaged. The system also
shuts the engine off if the operator's left foot is raised from
the interlock pedal with the mower and parking brakes
disengaged.

WARNING:

Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disconnect or bypass any switch; injury to
yourself and others or property damage could
result.

If the safety interlock system is malfunctioning or if you
want to ensure that it is working properly, perform the tests
in Table 4-1. Stop the test and have the system inspected
and repaired if:

4.3 INITIAL RUN-IN PROCEDURES (First
Day of Use or Approximately 10 Hours)

1. Check all belts for proper tension at 2, 4 and 8 hours;

4.4 DIESEL ENGINE BREAK-IN

The proper break-in of a new diesel engine can make a
difference in the performance and life of the engine. Perform
the following break-in procedure during the first 50 hours
of operation:

1. A new engine should be operated with as near full load
as possible. However, the engine must be allowed to
reach an operating temperature before operating at full
load conditions.

2. The engine oil should be checked twice daily. Higher
than normal oil consumption is not uncommon during
the initial break-in period.

3. Change the oil and filter element after the first 40
hours of operation.

4. Check all engine belts for proper tension after the first
10 hours of operation and adjust, if necessary. Refer
to Adjustments in Section 6.

4. Turn the ignition key switch to the PREHEAT position
until the indicator light for the glow plug glows bright
red. The colder the temperature, the longer it will take
to energize the glow plug. This step is not necessary
when starting a warm engine.

5. Turn the ignition key switch to 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 inhibit overheating the starter
motor. Prolonged cranking can damage the starter
motor and shorten battery life.

6. Allow engine to warm to operating temperature.

4.6 OPERATOR COMFORT ADJUSTMENTS

Two adjustments can be made to make your mowing job
comfortable. The steering handle can be adjusted up or
down and the seat can be adjusted forward or back.

5. During the break-in period, check and tighten all
engine hardware.

4.5 STARTING THE DIESEL ENGINE

CAUTION:

DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause “Runaway” engine condition
that could result in engine damage and/or
personal injury.

1. Be sure the fuel shut-off valve is completely open.
The valve is located in the fuel line between the fuel
tank and electric fuel pump (See Section 7).

2. Sit in the operators seat and depress the interlock foot
pedal with your left foot. Make sure the parking brake
and mower blade brake are engaged.

A. Adjusting Steering Handle Height

1. Remove the hardware securing the handle to the
steering shaft. Two sets of holes are available to
adjust the handle height.

2. Release the handle to lock the position.

Figure 4-5 Seat Adjustment

4.7 ADJUSTING GROUND SPEED AND

DIRECTION

-NOTE-

If you are not familiar with the operation of
the hydrostatic drive, practice turning and ma­neuvering with the foot controls before engag­ing the blades. Learn the operation in an open
area away from buildings, fences, or obstruc­tions. Learn the operation on a flat ground
before operating on slopes. Start maneuver­ing with SLOW engine speed until you are fa­miliar with all operating characteristics. Prac­tice maneuvering the mower until you can
make it go exactly where you intend.

1. To travel forward, depress the right foot pedal at the
toe. (See Figure 4-6). The further the pedal is de­pressed the faster the mower will travel forward.

Figure 4-6 Forward - Depress Toe End of Pedal

-NOTE-

Before shifting from forward to reverse, or re­verse to forward, come to complete stop then
shift the foot pedal to the desired direction.

2. To travel backwards (reverse), depress the right foot
pedal at the heel (See Figure 4-7). The further the
pedal is depressed the faster the mower will travel
backwards. Use slower traveling speed when traveling
backwards and observe the area behind you before
moving.

-NOTE-

If the mower is driven on public roads, it must
comply with state and local ordinances as well
as SAE J137 and/or ASME S279 requirements.
Contact your local authorities for regulations
and equipment requirements.

-NOTE-

The left operator foot pedal must be depressed
before operation.

Figure 4-7 Backward (Reverse) Operation- Depress

Heel End of Pedal

12

Section 4

3. Check that all systems function correctly.

4. When traveling, the throttle control can be adjusted to
increase or decrease travel speed.

5. Reduce speed when turning around trees, shrubs, etc.

IMPORTANT:

Avoid high-speed turns on all surfaces. Tires
can slip on grass and can wear rapidly on
concrete and asphalt.

6. When going over curbs, first activate the mower deck
lift switch to fully raise the deck to clear the curb. Go
FORWARD over the curb.

4.8 ENGAGING THE MOWER

1. Set engine throttle about 1/2 speed. Do not attempt
to engage the blade at high engine speed as this

shortens the electric clutch life  use only moderate
engine speed when engaging the blades.

3. Always operate the engine at full throttle to
properly maintain cutting speeds. If the engine
starts to lug down, reduce the forward speed to
allow the engine to operate at maximum RPM.

4.9 HILLSIDE OPERATION

WARNING:

To 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 limits
traction and steering control.

2. Engage the mower blades by moving the blade brake
lever down and to the right.

WARNING:

A safety interlock switch (left foot pedal) will
cause the engine to stop if the blade brake
is disengaged, and the left foot pedal is not
depressed. The function of the switch
should be checked by the operator raising
his left foot and disengaging the blade
brake; the engine should stop. If the switch
is not working, it should be repaired or
replaced before operating the mower. Do
not disconnect the interlock safety switches
because they are for the operator’s protec­tion.

-IMPORTANT-

Do not engage the mower blades when
transporting the mower across drives, loose
materials, etc.

2. To inhibit tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at a
reduced speed.

3. Keep tires properly inflated.

4. Always travel up or down the slope, whenever pos­sible; NEVER across the slope.

5. If the mower cannot climb the slope, the grade is too
steep for safe operation. Do not make another attempt
to climb the slope. Engage the blade brake to stop the
blades and back down slowly.

13

Figure 4-8 Proper Operation on Slope

Section 4

-IMPORTANT-

If at all possible, do not engage the mower
brake with engine running at high speed, since
premature wear of the electric clutch will oc­cur. Lower speed to near idle then engage the
brake.

CAUTION:

The blade brake stops the blades from rotating.
If the blades do not stop, contact your Scag
Dealer.

CAUTION:

Remove the key from the ignition switch when
leaving the mower unattended to inhibit children
and inexperienced operators from starting the
engine.

Figure 4-9 Improper Operation on Slope

4.10 STOPPING

1. Slow engine speed to idle.

2. Place the right foot pedal in the center (neutral)
position.

3. Engage the blade brake.

4. Engage the parking brake and turn ignition key to OFF.

4.1 1 AFTER OPERA TION

1. Park the mower on a flat and level surface and fully
lower the cutting deck to the ground. Stop the engine
and engage the parking and blade brakes. Remove the
key from the ignition switch.

-IMPORTANT-

If the radiator dirt screen is not removed and
cleaned after every use, the screen will be­come clogged with grass clippings, etc., block­ing the air flow through the radiator. This
will cause a high engine operating tempera­ture that may cause damage to the engine.

2. Clean the radiator dirt screen. See Section 7 for
radiator dirt screen removal and cleaning instructions..

3. Wash the entire mower after each use. Do not use high
pressure spray or direct the spray onto electrical
components.

14

Section 4

-IMPORTANT-

Do not wash a hot or running engine. Use
compressed air to clean the engine and the
radiator fins. Cold water will damage the
engine and/or radiator.

4. Keep the entire mower clean to inhibit serious heat
damage to the engine or hydraulic oil circuit.

5. Recheck the cutter drive belts for proper tension,
alignment and any signs of rubbing. Correct and adjust
as necessary.

6. Fill the fuel tank with fresh, clean fuel at the end of
every day of operation.

7. Check the tire pressure. Inflate tires if necessary.

4.12 MOVING MOWER WITH THE ENGINE

STOPPED

To free-wheel or move the mower around without the
engine running, rotate the dump valve handle (screw and
nut) located on the side of the hydraulic pump to full open
position. See Figure 4-10. Disengage the parking brake
and move the mower by hand. The lever must be returned
to the original position to operate the mower.

4.13 RECOMMENDATIONS FOR MOWING

1. Keep the mower deck and discharge chute clean.

2. Mow with sharp blades. A dull blade will tear grass,
resulting in poor lawn appearance and takes extra
power (slow mowing speed).

3. The discharge deflector must not be removed and must
be kept in the lowest position to deflect grass clippings
and thrown objects downward. Orient the side dis­charge away from sidewalks or street to minimize
cleanup of clippings. When mowing close to obstacles,
orient the discharge away from obstacles to reduce the
chance of property damage by thrown objects.

4. Cut grass when it is dry and not too tall. Mow
frequently and do not cut grass too short (cut off 1/3
or less of existing grass for best appearance).

5. Operate the engine at or near full throttle for best
cutting. Mowing with a lower RPM causes the mower
to not cut clean and tear the grass. The engine is
designed to be operated at full speed.

6. Use slow travel speed for trimming purposes.

7. When mowing tall or wet grass, mow the grass twice.
Raise the mower to the highest setting for the first pass
and then make a second cutting pass to the desired
height.

Dump Valve

Handle

Close

Figure 4-10 Dump Valve Handle

8. Be sure the mower is leveled properly for a smooth
cut. See Section 7, Adjustments.

Open

9. Use alternate stripe mowing pattern for best appear­ance and vary the direction of the stripe each time the
grass is mowed to avoid wear patterns in the grass.

4.14 ADJUSTING CUTTING HEIGHT

The mower deck height switch on the instrument panel is
used to adjust the cutting height of the deck. Do not adjust
the cutting height while the mower is moving. Stop the
mower, then activate the deck height switch to position the
deck at the desired height. A gauge is located on the right
front of the mower (See Figure 4-11) for use in selecting
the proper cutting height.

4.15 TILTING THE MOWER DECK

CAUTION:

Do not tilt the deck with the mower blades
rotating. Engage the blade brake before tilting
the deck. Bodily injury or damage to the mower
or property could result.

1. Stop the traveling movement of the mower and engage
the blade brake.

2. Use the deck tilt control switch on the instrument panel
to raise the deck.

3. Before lowering the deck, observe that there are no
objects under the deck. Remove any objects then,
activate the deck tilt switch to lower the deck.

ADJUSTMENTS

Section 6

6.1 P ARKING BRAKE ADJUSTMENT

WARNING:

Do not operate the mower if the parking brake is
not operable. Possible severe injury could
result.

The parking brake linkage should be adjusted whenever the
parking brake lever is placed in the Engage position and
the parking brake will not hold the mower from moving. A
minor adjustment can be made at the control lever by
loosening the jam nut shown in Figure 6-1 and turning the
rod in a clockwise direction to tighten the linkage. Tighten
the jam nut.

If this adjustment does not hold the mower from moving or
no more thread is available on the rod, contact your Scag
dealer before operating the mower.

6.2 FORW ARD/REVERSE NEUTRAL

ADJUSTMENT

The forward/reverse linkage should be adjusted whenever
the mower will not stay stationary when the forward/reverse
(right) foot pedal is placed in the neutral position.

1. Set the engine deck on jack stands so the wheels are
free to rotate.

2. Block the caster wheels to prevent an accident should
the unit fall off the jacks.

3. Start the engine and observe for drive wheel
rotation.

If the wheels consistently rotate when the foot control
is in neutral, go to step 4.

If the drive wheels intermittently rotate, i.e. the drive
wheels sometimes rotate and sometimes do not when
the foot pedal is not depressed, then check the neutral
adjustment bolt for zero free play in the neutral control
spring.

-NOTE-

If you turn the nut too much, you will com­press the spring, making too much end play.
Go to step 4.

4. If the drive wheels rotate in rearward travel direction,
turn the adjustment bolt (Figure 6-1) clockwise until
rotation stops. If the drive wheels rotate in the for­ward travel direction, turn the adjusting bolt counter­clockwise until rotation stops.

5. Check the adjustment of the right foot pedal for full
forward speed. The bottom of the foot pedal should be
1/4 inch from the top of the foot plate (See Figure 6-1)
when the pump is stroked in the full forward position.

To make an adjustment, loosen the jam nut at the
pump control bellcrank (Figure 6-1). Depress the foot
pedal and turn the control rod until 1/4 inch is obtained
between the bottom of the foot pedal and the top of the
foot plate. Tighten the jam nut.

6. Start the engine. The drive wheels should rotate only
when the forward/reverse foot pedal is depressed.

6.3 THROTTLE CONTROL LINKAGE

ADJUSTMENT

Should the throttle control lever not stay in
position after moving it to increase or decrease the
engine speed, the throttle linkage must be
tightened. Hold the lock nut (Figure 6-2) with a wrench
while turning the bolt clockwise to tighten the throttle lever
against the friction plate. Do not overtighten as the control
lever will be hard to move.

6.4 CUTTER BRAKE LINKAGE

The cutter brake linkage is self-adjusting. If the brake will
not hold the cutter blades from turning, consult your Scag
dealer. Do not operate the mower if the cutter brake is not
functioning properly.

6.5 FAN BELT ADJUSTMENT

1. Remove the pump belt guard to gain access to the fan
drive idler bracket.

2. Loosen the two bolts (A and B, Figure 6-3). Using a
3/8 inch ratchet wrench installed in hole C, rotate the
bracket until 1/2 inch deflection in the belt is observed
using 10 pounds of pressure on the belt. See Engine
Drive Belts, section 7.9 for checking method.

If the engine speed must be increased or decreased, consult
your Scag dealer.

6.10 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 dealer for belt
adjustment.

6.11 CUTTER DECK ADJUSTMENTS

Due to many conditions that exist, it is difficult to suggest a
setting that will work for every lawn. However, two
adjustments should be made on the cutter deck to ensure
proper grass cutting: DECK LEVEL AND PITCH.

-NOTE-

Before checking for proper cutter deck adjust­ments, check that all tires are inflated to the
correct pressure.

DECK LEVEL is the adjustment to level the deck side-to­side. For proper blade cutting, the deck should be level.
To check for level, place the mower on a flat, level surface.
On the right side of the deck, measure from the ground to
the bottom of the cutter deck (Figure 6-7). Then, take a
measurement on the left side of the deck. Both measurements
should be equal. If different, adjust the deck to level.

To level the deck, loosen the adjusting nut (Figure 6-8) and
lift or lower the deck until the left side measurement equals
the right side measurement. Tighten the adjusting nut.

Adjusting Nut

Figure 6-8 Leveling the Cutter Deck

PITCH is the adjustment to angle the blades from rear to
front. For proper grass cutting, the blades should be angled
forward. To check proper blade pitch, place the mower on
a flat, level surface. Measure the distance from the ground
to the rear of the mower deck ("X", Figure 6-9). Then,
measure on both sides of the mower deck the distance from
the ground to the front of the deck ("Y"). The front should
be 1/4 inch lower than the rear. If not correct, adjust the
pitch.

Figure 6-7 Measuring Height of Deck

= " Y "

Figure 6-9 Pitch Measurement

1. To adjust the pitch, loosen the jam nut on both
adjusting rods (See Figure 6-10).

" X " =

2. Turn the adjusting rods counter-clockwise to lower the
front of the deck and clockwise to raise the front of the
deck. When a difference of 1/4 inch from front to rear
is obtained on left and right, tighten both jam nuts.

6.12 BLADE CUTTING HEIGHT

ADJUSTMENT

The blade cutting height is adjusted by actuating the deck
height switch on the instrument panel. However, if the
cutting height compared to what is shown on the cutting
height gauge (See Figure 6-12) is in question, the cutting
height should be checked. To check the cutting height, lift
the discharge chute and measure from the ground to the
cutting edge of the blade (See Figure 6-11). If the
measurement is different from what is registered on the
gauge, adjust the gauge rod to the proper setting.

LIMITED WARRANTY-COMMERCIAL EQUIPMENT

Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judgment
of Scag, to be defective in materials or workmanship, will be repaired or replaced by an Authorized Scag Service Dealer
without charge for parts and labor. This warranty is limited to the original purchaser and is not transferable. Proof of
purchase will be required by the dealer to substantiate any warranty claims. All warranty work must be performed by an
Authorized Scag Service Dealer.

This warranty is limited to the following specified periods from the date of the original retail purchase for defects in materials
or workmanship:

* Wear items including drive belts, blades, hoses and tires are warranted for 90 days.
* Batteries are covered for 90 days.
* Frame, deck, and structural components including oil reservoir, fittings, and oil cooler are

warranted for 1 year.
* Engines and electric starters are covered by the manufacturers warranty period.
* Drive system components are warranted for 1 year by the component manufacturer, in

conjunction with Scag Power Equipment. (Excluding fittings, hoses, cooling system, oil

reservoir, drive belts).
* Electric clutch components are warranted for 1 year.

Any Scag product used for rental purposes is covered by a 90 day warranty.

The Scag mower, including any defective part must be returned to an Authorized Scag Service Dealer within the warranty
period. The expense of delivering the mower to the dealer for warranty work and the expense of returning it to the owner
after repair will be paid for by the owner. Scags 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 Operators 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 not been
assembled or installed as specified in the Operators Manual and Assembly Manual. The warranty does not cover any mower
that has been altered or modified, changing performance or durability. In addition, the warranty does not extend to repairs
made necessary by normal wear, or by the use of parts or accessories which, in the reasonable judgment 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 one (1) year warranty period or ninety (90) days for mowers used

or otherwise, are disclaimed in their entirety after the expiration of the appropriate one year or ninety day warranty period.
Scags 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,
mechanics 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.
