SAFETY INTERLOCK SYSTEM4.2

The mower is equipped with an interlock system

intended to protect the operator and others from injury.

This is accomplished by preventing the engine from

starting unless the deck drive is disengaged, the neutral

lock lever is in the neutral lock position, and the operator

is in the operating position. The system shuts off the

engine if the operator steps off the operator platform

with the deck drive engaged or if the neutral lock lever

is placed in the drive position (D) and the parking brake

is applied. Never operate equipment with the interlock

system disconnected or malfunctioning.

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.

INITIAL RUN-IN PROCEDURES4.3

FIRST DAY OF USE OR APPROXIMATELY 20 HOURS

Check all belts for proper alignment and wear at 2, 4 1. and 8 hours.

Change the engine oil and oil filter after the first 20 2. hours of operation. See Section 7.4.

Check oil level in the hydraulic system reservoir. 3. See Section 7.3

Check for loose hardware. Tighten as needed.4.

Check interlock system for proper operation. 5. See Section 4.2.

Check tire pressure. Adjust pressure if necessary. 6. See Section 7.10.

STARTING THE ENGINE4.4

CAUTION

DO NOT USE STARTING FLUIDS. Use of starting

ﬂ uids 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.

Be sure the fuel shutoff valve, located by the fuel 1. tank, is completely open. See Section 7.5.

Place the neutral lock lever in the neutral position 2. and disengage the the cutter blades .

Engage the parking brake.3.

Section 4

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. 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.

- 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, place the neutral lock lever in the drive (D) 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 forward and

to decrease speed, pull the steering control levers back.

See Figure 4-2.

To stop the forward travel completely, pull the steering

control levers back to the neutral position.

To steer the mower to the left while traveling forward,

pull the left steering control lever back. The further the

steering control is pulled back, the quicker the mower will

turn left. See Figure 4-3.

To steer the mower to the right while traveling forward,

pull the right steering control lever back. The further the

steering control is pulled back, the quicker the mower will

turn right. See Figure 4-3.

- NOTE -

Smooth operation of the steering control levers will

produce smooth mower operation. While learning

the operation of the steering controls, keep the

travel speed low.

REVERSE TRAVEL

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 steering control 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.

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 and place the neutral

lock lever in the neutral (N) position.

entire are behind the mower.

CAUTION

Before backing up, observe behind the mower for

persons and obstructions. Clear the area before

backing up. Possible injury or property damage

could occur.

- 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. This is normal.

Section 4

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

Always operate the engine at full throttle to properly

4. maintain cutting speed. If the engine starts to lug

down, reduce the forward speed and allow the

engine to operate at maximum RPM.

HILLSIDE OPERATION4.7

WARNING

DO NOT operate on steep slopes. Under no

circumstances should the machine be operated

on slopes greater than 20 degrees. ALWAYS

FOLLOW OSHA APPROVED OPERATION.

This mower has been designed for good traction and 1. 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.

Stay two cut widths away from slopes, drop offs, 2. ditches and retaining walls.

To prevent tipping or loss of control, do not start or 3. stop suddenly, avoid unnecessary turns and travel

at reduced speed. If tires lose traction, disengage

blades and proceed slowly off the slope.

Avoid sudden starts when mowing uphill. Sudden 4. starts may cause the machine to tip backwards.

Loss of traction may occur when traveling down hill. 5. Weight transfers to the front of the machine and

may cause the drive wheels to slip causing loss of

braking or steering.

Never back down hill.6.

Keep tires properly inflated.7.

PARKING THE MOWER4.8

Park the machine on a flat, level surface only. Do not 1. park the machine on an incline.

Disengage the cutter blades.

Shift the neutral lock lever into the neutral (N) 3. position.

Engage the parking brake.4.

Slow the engine to idle speed.5.

Turn the ignition key to the OFF position and remove 6. the key.

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.

After the mower has cooled down, fill the fuel tank

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

operation. See Engine Owner's Manual for proper

octane requirements.

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

REMOVING CLOGGED MATERIAL4.10

DANGER

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.

If the discharge chute becomes clogged, shut off

1. the engine and remove the ignition key. Using a stick

or similar item, dislodge the clogged material. Then

resume normal mowing.

Section 4

MOVING MOWER WITH ENGINE 4.11

STOPPED

To “free-wheel” or move the mower around without the

engine running, place the dump valve levers in the FREE-

WHEEL position. Disengage the parking brake and move

the mower by hand. The dump valve levers must be

returned to the DRIVE position and torqued to 7-10 ft/lbs

to drive the mower.

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

DO NOT operate without Discharge Chute,

Mulching Kit, or entire Grass Catcher properly

installed.

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.

Cut grass when it is dry and not too tall. Do not cut

3. grass too short (cut off 1/3 or less of existing grass

for best appearance). Mow frequently.

Keep mower and discharge chute clean.

When mowing wet or tall grass, mow the grass twice. 5. 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

inch to 4-1/2 inches at 1/4-inch intervals. To adjust the

cutting height:

WARNING

DO NOT adjust the cutting height with the mower

blades rotating. Disengage the power to the cutter

blades, put the neutral lock lever in the neutral

position, apply the parking brake and then adjust

cutting height.

Disengage the power to the cutter blades.

Pull on the cutter deck lift lever lever all the way 2. backward until it locks in place. See Figure 4-5.

Insert the lanyard pin into the cutting height index

3. at the desired cutting height. Pull backward on the

cutter deck lift lever, push and hold the lock button

See Figure 4-5. Slowly release the cutter deck lift

lever. A deck height decal is located on the cutting

height index as an aid in adjusting the deck to the

desired height.

adjustments.

Section 6

-NOTE-

Before proceeding with this adjustment, be sure

that the caster wheels turn freely and that the tire

pressure in the drive wheels is correct. If the tire

pressure is not correct, the machine will pull to the

side with the lower pressure.

If at full speed the mower pulls right, it is an

1. indication that the left wheel is turning faster than

the right wheel. To adjust this condition, proceed as

follows:

A. Stop the machine and place the steering control

levers in the neutral position. Loosen the lock nuts

securing the ball joints at each end of the LH steering

control rod. Rotate the control rod to lengthen the rod

and tighten the lock nuts. This will cause the control

rod to stroke the LH pump less, slowing down the LH

wheel. See Figure 6-3.

- NOTE -

If after making the adjustment as outlined in step

1A, the machine creeps forward or backward, the

neutral adjustment must be made as described

on page 20.

If at full speed the mower pulls left, it is an indication

2. that the right wheel is turning faster than the left

CUTTER DECK ADJUSTMENTS6.6

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 all tires are properly inflated.

Section 6

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 LH side of the machine, check the

distance from the top of the cutter deck to the floor. Next

check the distance from the top of the cutter deck to the floor

on the RH 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:

On the front RH side of the cutter deck locate the

1. cutter deck adjustment levers. Loosen the elastic stop

CUSTOM-CUT BAFFLE ADJUSTMENT

The Custom-Cut Baffle is designed to deliver optimum

airflow and superior cutting performance in any type of

grass. The Custom-Cut Baffle can be raised or lowered

to precisely tailor the deck's performance for the type of

grass being cut. The baffle can be set in seven (7) different

positions for optimum performance.

A. 3-1/2" or 3-3/4" Position - See Figure 6-7. For very

tall, wiry or tough-to-cut grass.

B. 4" (factory setting), 4-1/4" or 4-1/2" Position - See

Figure 6-7. 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 6-7. 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:

Park the machine on a flat surface, apply the parking 1. brake, shut off the engine and remove the key.

Place the cutter deck in the transport position.2.

Remove the hardware securing the Custom-Cut 3.

Baffle to the cutter deck.

Clutch Air Gap AdjustmentFigure 6-10.

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.

FRONT WEIGHT ADJUSTMENT6.8

This 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.

The 36" model comes standard with two (2) weights

installed and the 48" and 52" models come standard with

one (1) weight installed. All models must not be operated

with less than the number of weights listed above.

ELECTRIC CLUTCH ADJUSTMENT6.7

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

B. CHANGING HYDRAULIC OIL

The hydraulic oil should be changed after every 500 hours

or annually, whichever occurs first. The oil should also be

changed if the color of the fluid has become black or milky.

A black color and/or a rancid odor usually indicates possible

overheating of the oil, and a milky color usually indicates

water in the hydraulic oil.

- IMPORTANT -

The hydraulic oil should be changed if you notice

the presence of water or a rancid odor to the

hydraulic oil.

Park the mower on a level surface, stop the engine 1. and remove the ignition key.

Place a suitable container under the hydraulic 2. oil filter. Remove the fill cap from the reservoir.

Remove the drain plug from the fitting on the filter

base. See Figure 7-3. Allow the fluid to drain into the

container and properly discard it.

Re-install the drain plug into the tee fitting and be 3. sure it is tight.

- NOTE -

Before refilling the hydraulic oil reservoir the

hydraulic oil filter should be changed as outlined

in Procedure C "Changing Hydraulic Oil Filter

Element".

Fill the reservoir to full 2-1/4" inches below the filler 4. neck with 20W50 motor oil.

Replace the reservoir fill cap. Start the engine and 5. drive forward and backward for two minutes. Check

the oil level in the reservoir. If necessary, add oil to

the reservoir.

HYDRAULIC SYSTEM7.3

A. CHECKING HYDRAULIC OIL LEVEL

The hydraulic oil level should be checked after the first 8

hours of operation. Thereafter, check the oil after every

200 hours of machine operation or monthly, whichever

occurs first.

- IMPORTANT -

If the oil level is consistently low, check for leaks

and correct immediately.

Wipe dirt and contaminants from around the

1. reservoir cap. Remove the cap from the hydraulic oil

reservoir.

Visually check the level of hydraulic oil. Hydraulic 2. oil must be at least 2-1/4" inches from top of the

filler neck. If the level cannot be determined visually,

use a clean tape measure to check the level. If the

fluid is low, add 20W50 motor oil. DO NOT overfill;

(overfilling the oil reservoir may cause oil seepage

around the cap area).

Clean the fill cap and install it onto the reservoir.3.

1. sources of ignition.

Use only an approved gasoline container.

Never remove the gas cap or add fuel with the 3. engine running. Allow the engine to completely cool

before fueling.

Never fuel the machine indoors or in an enclosed 4. trailer.

Never store the machine or fuel container where 5. there is an open flame, spark or pilot light such as on

a water heater or other appliances.

Never fill containers inside a vehicle or on a truck 6. or trailer bed with a plastic liner. Always place

containers on the ground away from your vehicle

before filling.

Remove the machine from the truck or trailer and

7. fuel on the ground. If this is not possible, then refuel

the machine with a portable container, rather than

from a gasoline dispenser nozzle.

Keep the nozzle in contact with the rim of fuel tank 8. or container opening at all times until fueling is

complete. Do not use a nozzle lock-open device.

If fuel is spilled on clothing, change clothing

9. immediately and wash affected skin.

Replace gas cap and tighten securely.

BATTERY - ELECTRIC START MODELS7.7

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.

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.

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.

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.

Section 7

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

negative ground system.

When connecting the jumper cables, connect the

2. positive cable to the positive battery post, then

connect the negative cable to the negative battery

post.

CUTTER BLADES7.8

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.

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

4. 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.

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.

Sharpen the cutting edge at the same bevel as the 1. original. See Figure 7-6. Sharpen only the top of the

cutting edge to maintain sharpness.

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. “Non-Commercial” use is deﬁned as a single property owner,

where the single property is the residence of the owner of the mower. If the mower is cutting more than the owners single property, it is

deemed commercial use and the “non-commercial” warranty does not apply. Scag Power Equipment reserves the right to deny and / or

void the non-commercial warranty if it believes it to be in commercial use.

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 two (2) year for commercial

use, three (3) years for non-commercial use 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. 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.
