on the hydraulic pumps, used to “free-wheel” the

mower. Rotating the levers clockwise until they stop

allows the unit to move under hydraulic power. The

levers must be in this position during operation of the

mower. Rotating the levers counter-clockwise allows

the mower to be moved by hand (free-wheeling).

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.

hours of operation. (See Section 7.4.)

4.5 GROUND TRAVEL AND STEERING

-IMPORTANT-

3. Check hydraulic oil level in reservoir. (See Section

7.3.)

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

4. Check for loose hardware. Tighten as needed.

5. Check interlock system for proper operation. (See

Section 4.2.)

attempting to mow. Learn the operation on flat

ground before operating on slopes.

6. Check tire pressure. Adjust pressure if necessary.

(See Section 7.10)

-IMPORTANT-

Start practicing with a slow engine speed and

slow forward travel.

4.4 STARTING THE ENGINE

Learn to feather the steering controls to obtain

a smooth operating action.

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.

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.

1. Be sure the fuel shutoff valve, located behind the

operator's seat, 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.

To stop the forward travel, pull the steering control levers

back to the neutral position.

4. If the engine is cold, choke the engine as needed.

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.

5. Move the engine throttle control to about half engine

speed.

6. 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.

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.

7. Allow engine to warm before operating the mower.

Section 4

-NOTE-

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.

Smooth operation of the steering levers will

produce smooth mower operation. While

learning the operation of the steering controls,

keep the travel speed low.

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.

-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)

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.

Reverse Travel

2. Engage the deck drive by pulling out on the yellow

switch, located on the instrument panel, (Figure 4-3)

to the engage position.

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.

PULL UP TO ENGAGE

PUSH DOWN TO DISENGAGE

STT99CES

Figure 4-3 Cutter Engage Switch

To travel in reverse, pull both handles back. Keep the

travel speed low while traveling in reverse.

-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.

-NOTE-

The mower will not travel straight in reverse.

Slight adjustments must be made using the

steering controls.

3. To disengage the deck drive, push the switch in to the

disengage position.

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.

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.

Section 4

-IMPORTANT-

4.7 HILLSIDE OPERATION

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.

WARNING:

2. Keep the entire mower clean to inhibit serious heat

damage to the engine or hydraulic oil circuit.

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. ALWAYS FOLLOW OSHA APPROVED

OPERATION.

3. Check the drive belts for proper alignment and any

signs of wear. Correct and adjust if necessary.

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.

To avoid injury from burns, allow the mower to

cool before removing the fuel tank cap and

refueling.

4. After the mower has cooled down, fill the fuel tank

with fresh, clean fuel at the end of every day of

operation.

2. To prevent tipping or loss of control, do not start or

stop suddenly, avoid unnecessary turns and travel at

reduced speed.

5. Check the tire pressure. Adjust pressure if necessary.

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

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.

4.9 AFTER OPERATION

1. Wash the entire mower after each use. Do not use

high pressure spray or direct the spray onto electrical

components.

Download from Www.Somanuals.com. All Manuals Search And Download.

Section 4

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.

4.10 REMOVING CLOGGED MATERIAL

ROTATING BLADES

6. Use a slow travel speed for trimming purposes.

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.

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.

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 FREE-

WHEEL 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.

4.12 RECOMMENDATIONS 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.

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.

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.

-NOTE-

Before proceeding with the cutter deck adjustments,

be sure that all tires are properly inflated.

Cutter Deck Level

Check the distance from the bottom 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 bottom 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

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:

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. Loosen the jam nuts on both adjusting rods.

(See Figure 6.5)

1. On the front LH side of the cutter deck locate the

cutter deck adjusting bolt. (See Figure 6.5)

2. Using a wrench on the spring compression nut (See

7.7 BATTERY

WARNING:

A. Checking Electrolyte Level and Cleaning

Battery

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.

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.

BATTERY ELECTROLYTE FIRST AID

EXTERNAL CONTACT — Flush with water.

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.

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. Loosen the two plastic wing nuts and then remove the

battery cover.

2. Remove the battery cell caps. Visually inspect

electrolyte level in the cells. If electrolyte is

B. Charging the Battery

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.

Refer to the battery charger’s manual for specific

instructions.

-IMPORTANT-

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.

3. Clean the cable ends and battery posts with steel wool.

Use a solution of baking soda and water to clean the

battery. Do not allow the solution to enter the battery

cells.

DO NOT charge a frozen battery. It may explode and

cause injury. Let the battery warm before attaching a

charger.

4. Tighten the cable connections securely and apply a

light coat of silicone dielectric grease to the terminal

connections to prevent corrosion.

WARNING:

Always wear proper hand and eye protection

BATTERIES PRODUCE EXPLOSIVE GASES.

Charge the battery in a well ventilated space

so gases produced while charging can

dissipate.

when working with cutter blades.

3. Check the cutter blades for straightness. If the cutter

blades appear bent, they will need to be replaced.

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.

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.

C. Jump Starting

4. If a blade cutting edge is dull or nicked, it should be

sharpened. Remove the blades for sharpening. See

"Blade Replacement."

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.

-NOTE-

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.

LIMITED WARRANTY-COMMERCIAL EQUIPMENT

Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judg-

ment 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 clutches have a Limited Warranty for 2 year (Parts and labor 1st year; Parts only

2nd year).

* Cutter Spindle Assemblies 46631 have a Limited Warranty for three years (Parts and

labor 1st year; Parts only 2nd and 3rd 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 obliga-

tion 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. 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.

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, 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.
