BEFORE OPERATING WHILE OPERATING

1. Know the operating controls and how to stop quickly.

2. Do not allow children to operate the machine.

Do not allow adults to operate the machine without proper instruction.

3. Remove all debris or other objects that might be picked up and thrown by the cutter blades. Keep all bystanders away from the mowing area.

6. Fill the fuel tank with clean, fresh gasoline, with a minimum octane rating of 87. Avoid spilling gasoline. Gasoline is highly flammable, handle it carefully.

A. Use an approved gasoline container.

B. Do not fill the tank while the engine is hot or running.

C. Do not smoke while handling gasoline.

D. Fill the fuel tank outdoors and up to approximately 1" (25 mm) below the bottom of the filler neck.

E. Wipe up any spilled gasoline.

7. Before attempting to start the engine, move the blade engagement switch to the OFF position and apply the parking brake.

1. Start the engine when the cutter blades are disengaged, the parking brake is on and the right foot pedal is in the neutral position.

2. Do not run the engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and could possibly be deadly.

4. Keep all shields, safety devices, and decals in place. If a shield, safety device or decal is defective or damaged, repair or replace it before operating. Also, check all nuts, bolts and screws for proper tightness, to assure the machine is in safe operating condition.

5. Do not operate the machine while wearing sandals, tennis shoes, sneakers or shorts. Also, do not wear loose fitting clothing which could get caught in moving parts. Always wear long pants and substantial shoes. Wearing safety glasses and safety shoes is advisable and required by some local ordinances and insurance regulations.

3. Using the machine demands attention. To prevent loss of control:

A. Mow only in daylight or when there is good artificial light.

B. Watch for holes or other hidden hazards.

C. Do not drive close to a drop-off, ditch, creek bank, or other hazard.

D. Reduce speed when making sharp turns and when turning on hillsides.

E. Do not operate where conditions are slippery.

4. The discharge chute must always be installed and in the down position on the side discharge cutter deck except when the Scag optional grass catcher or mulching plate are properly installed.

If the discharge area should plug, shut the engine off and wait for all movement to stop before removing the obstruction.

5. Disengage the blades and wait for them to stop before crossing gravel drives, walks or roads.

6. Shut the engine off and wait until the blades come to a complete stop before removing the grass catcher container.

7. Never raise the cutter deck while the blades are rotating.

8. Always park the mower and/or start the engine on a level surface. Apply the parking brake to prevent the mower from moving when you are not in the operators position.

2

9. If the cutting blades should strike a solid object or the equipment should start to vibrate abnormally, stop the engine, disconnect the spark plug wire, and check immediately for the cause.

Vibration is generally a warning of trouble.

Check the machine for damaged or defective parts. Repair any damage before starting the engine or operating the cutter deck. Be sure the blades are in good condition and the blade bolts are tight.

10. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tipping or loss of control. Be especially cautious when changing directions on slopes.

MAINTENANCE AND STORAGE

1. Disconnect the spark plug wire from the spark plug to prevent accidental starting of the engine when servicing, adjusting or storing the machine.

2. If the mower must be tipped to perform maintenance or adjustment, remove the battery, drain the gasoline from the fuel tank and the oil from the crankcase.

3. To reduce potential fire hazard, keep the engine free of excessive grease, grass, leaves and accumulations of dirt.

4. Be sure the machine is in safe operating condition by keeping nuts, bolts, and screws tight. Check the blade mounting bolts and nuts frequently to be sure they are tightened.

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. ALWAYS FOLLOW OSHA

APPROVED OPERATION.

5. If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing and other parts of the body away from the cutter deck blades and other moving parts.

11. Do not touch the engine or muffler while the engine is running or soon after it is stopped.

These areas could be hot enough to cause a burn.

6. Do not overspeed the engine by changing governor settings. To be sure of safety and accuracy, have an authorized dealer check maximum engine speed with a tachometer.

12. Before leaving the operators position or leaving the mower unattended, move the right foot pedal into the neutral position, apply the parking brake, and move the blade engagement switch to OFF.

Shut the engine OFF and remove the key.

7. The engine must be shut off before checking the oil or adding oil to the crankcase.

13. Do not pass or stand on the grass discharge side of any mower with the engine running. Stop the cutter blades when another person approaches.

8. Allow the engine to cool before storing the mower in any enclosure such as a garage or storage shed. Make sure the fuel tank is empty if the machine is to be stored in excess of 30 days.

Do not store the mower near any open flame or where gasoline fumes may be ignited by a spark.

3

9. Always store gasoline in a safety-approved, red container.

10. Be careful when servicing the battery as it contains acid, which is corrosive and could cause burns to skin and clothing.

11. Batteries release explosive gases when being charged or discharged. Keep batteries away from any source of sparks and/or flame.

12. Make sure all hydraulic connections are tight and all hydraulic hoses and lines are in good condition before starting the machine.

13. Hydraulic fluid is under high pressure. If you need service on your hydraulic system, please see your authorized Scag dealer.

MOWER OPERATION

1. Read and understand the safety instructions before attempting to operate this machine.

2. Before starting the engine:

* Check the oil level in the engine and the hydraulic reservoir.

* Fill the fuel tank with clean, fresh, lead-free gasoline.

* Open the fuel valve on the bottom of the fuel tank.

-NOTE-

Use gasoline with an octane rating no less than

87.

INITIAL RUN-IN PROCEDURES

(FIRST DAY OF USE OR APPROXI-

MATELY 10 HOURS)

1. Check the belts for proper tension at 2, 4 and 8 hours. Adjust as needed. (See Belt Tension, page 7).

2. Check the neutral adjustment. (See Adjustments, page 6)

3. Check the tires for proper pressure.

Caster Wheels

Drive Wheels

25 psi.

15 psi.

Rear Steering Wheel 15 psi

4. Check for loose hardware. Tighten as needed.

5. Check the safety switches for proper adjustment:

* The engine should crank and start if the machine is in neutral, the PTO engagement switch is OFF and the parking brake is ON.

6. Apply lubricant to all the grease fittings. Lubricant was applied at the factory. This is just a precautionary check to make sure that all the fittings have been lubricated.

4

* The right hand foot pedal must be in the

NEUTRAL position.

* The blade clutch switch must be in the OFF position.

* The parking brake must be ON.

3. Start the engine:

* Choke as required. If the engine is cold, pull the choke knob out. When the engine starts, slowly push the choke in. If the engine stalls, repeat the above operation. When the engine is warm, choking may not be necessary.

4. Depress the left hand operator presence pedal.

5. Engage the cutter blades by lifting and pushing the blade cluch switch into the ON position. Pull the switch to the OFF position to disengage the cutter blades.

-NOTE-

When the PTO is engaged or (possibly) disengaged, a squealing sound from the underside of the machine is normal. It is caused by the electric clutch plates meshing as the cutter blades come up to speed. For best equipment life, engage the clutch with the engine at 1/2 throttle, not under full load.

WARNING:

If you are not familiar with the operation of the hydrostatic drive, practice turning and maneuvering before engaging the cutter blades.

5. Release the parking brake. Depress the right foot pedal at the toe end to drive forward (See

Figure 1) or depress the pedal at the heel end to drive in reverse. (See Figure 2)

7. To "freewheel" or move the machine around without the engine running, rotate the dump valve lever located on the left rear of the engine deck to the freewheel position (See Figure 3). The lever must be returned to the drive position to operate the machine.

ADJUSTMENTS

PARKING BRAKE

Minor brake adjustments can be made by loosening the top nut on both brake cables (see figure

4). Back the nuts off approximately 1/4". While pulling one cable downward, tighten the bottom nut on the cable until it touches the bottom of the brake cable mount. Tighten both the top and bottom nuts to lock the cable in place. Repeat the above steps for the second brake cable. Make sure that both cables are adjusted evenly so that the brakes do not cause the mower to pull to the left or right.

-NOTE-

This is a minor brake adjustment. If the brakes do not function properly after this adjustment, see your Scag Service Dealer before operating your mower.

4. If the drive wheels rotate in the forward travel direction, turn the adjustment bolt clockwise until the tire rotation stops. If the drive wheels rotate in the backward travel direction, turn the adjustment bolt counter-clockwise until the tire rotation stops (See Figure 5).

Spring

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

2. Block the caster wheels to prevent an accident should the machine fall off the jack stands.

3. Start the engine and determine if the drive wheels rotate.

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

9/16" Socket

Figure 5. Neutral Adjustment

SGB029

5. Check the adjustment of the right foot control pedal for full forward speed. The pedal should rest on the foot plate when the pump is stroked in the full forward position. To make an adjustment, disconnect the ball joint from the pedal arm and loosen the jam nut (See Figure 6). Place the foot control pedal forward against the foot rest and adjust the ball joint on the rod until the stud aligns with the hole in the arm. Bolt the ball joint to the arm and tighten the jam nut.

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

-NOTE-

DO NOT OVERTIGHTEN. If you turn the adjustment bolt too much you will compress the spring, making too much end play. Go to step 4.

CUTTER DECK ADJUSTMENTS

Due to the many conditions that exist, it is difficult to suggest a setting that will work for every lawn.

There are, however, two adjustments that should be made on the cutter deck: pitch and height.

PITCH is the angle of the blades (comparing front to rear).

HEIGHT is the nominal distance that the blade is off the ground. This measurement is made with the blades pointed side to side and distance is measured between cutting tip and ground.

Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mounting bolts to the top of the spindle shaft or to the bottom of the spindle shaft. All blades should be positioned equally (See Figure10).

The unit is shipped with one spacer on top of spindle and four underneath (See Figure 10).

This adjustment does not affect blade pitch.

Hex Nut-Torque to 75 Lb-Ft

Cutter Blade

Spacer 1/4"

-NOTE-

For best results, keep the cutter deck high in relation to the engine deck and the blades low in the cutter deck; ie. 4 or

5 spacers below the spindle shaft.

Additional range to the cutting height can be achieved by repositioning the cutter deck in relationship to the engine deck. This adjustment also affects the pitch of the deck.

There are three positions for mounting the cutter deck (See Figure 11). For cutting in the lowest position, mount the cutter deck in the top hole (A).

For cutting in the highest position, mount the deck in the lowest hole (C). Setting the cutter deck height will be determined by the type of cutting conditions.

Caster spacers also can be repositioned to change the cutting heights and to change the pitch of the deck (See Figure 12).

To adjust the caster spacers, raise the deck and remove the pin and caster wheel. Reposition the caster spacers as needed, then replace the caster, top spacers and pin. Make the same adjustments on the other caster wheel.

CUTTER BLADES

CAUTION:

Blades have a sharp cutting edge. Wear protective gloves or wrap blades with protective material when removing, sharpening and installing blades.

STEERING CABLE ROUTING

When the steering cable is routed between the front pulley and the rear steering collar, it is very important that the cable does not rub where it crosses. The top of the cable end from the front pulley must go over the top of the lower cable end (See Figure 14). The cable should be tightened until the slack has been removed. The cable should not be under tension. Do not overtighten the adjusting nuts on the rear steering collar pulley.

Scags 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 Operators 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 Operators 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 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.
