8. 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.

WARNING:

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after

handling.

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. Use jack stands to support the machine when required.

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

4. Park the machine on level ground. Never allow untrained personnel to service the machine.

9. 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.

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

11. 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.

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

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

14. Batteries release explosive gases when being charged or discharged. Keep batteries away from any source of sparks and/or flame. Charge batteries in an open, well ventilated area.

5. Disconnect battery or remove spark plug wires before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

6. Use care when checking blades. Wrap the blades or wear gloves and use caution when servicing them. Only replace blades. Never straighten or weld them.

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

WARNING:

Hydraulic fluid is under high pressure. Keep body and hands away from pinholes or nozzles that eject hydraulic fluid under high pressure. If you need service on your hydraulic system, please see your authorized Scag dealer . If hydraulic fluid is injected into the skin, it must be surgically removed within a few hours by a doctor or gangrene may result.

INITIAL RUN-IN PROCEDURES (FIRST DAY OF USE OR APPROXIMATELY 10 HOURS)

1. Check the belts for proper tension at 2, 4 and 8 hours. Adjust as needed. (See Belt Tension, page 9).

2. Check the neutral adjustment. (See Adjustments, page 8)

3. Check the tires for proper pressure.

Caster Wheels Flat Free Drive Wheels 12 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.

7. 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.

Page 12

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.

* 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:

-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 3/4 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)

-NOTE-

The left side operator presence pedal must be depressed for operation.

* 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 pulling the blade clutch switch into the ON position. Push the switch to the OFF position to disengage the cutter blades.

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.

6. When driving over curbs, disengage the cutter blades and raise the cutter deck to clear the curb. Drive forward over the curb. After the curb is clear, lower the cutter deck back to normal operating position. Be sure to leave slack in the cable after lowering the cutter deck.

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.

-NOTE-

To prevent damage to the hydraulic system, do not exceed 1MPH when moving the machine in the freewheel postion.

NEUTRAL ADJUSTMENT

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.

Page 14

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

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-

If there is free play in the foot pedal have your SCAG servicing dealer inspect the machine and repair it as needed.

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).

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.

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.

Page 16

Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mounting bolts to the top or to the bottom of the spindle shaft. All blades should be positioned equally (See Figure 10).

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

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.

This adjustment does not affect blade pitch.

Figure 11. Cutter Deck Height Adjustment

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.

To adjust the blade height, move any number of the five 1/4" thick spacers on the blade mounting bolts to the top of the spindle shaft or below the spindle shaft.

-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.

CUTTER BLADES

CAUTION:

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

Angle Blade Back

Do Not Cut In

A. 3" Position - baffle is installed using the top set of

holes on the front baffle welded inside the cutter deck. (See Figure 15). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry , tough to cut grass.

B. 3-1/2" Position (factory setting, Advantage Deck) -

baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. (See Figure 16). For general purpose cutting, place the Custom-Cut Baffle in the 3-1/2" position. This gives the best mix of cutting performance in all types of grass.

X Must NOT Exceed

1/3 Blade Width

SGB033

Figure 13. Blade Sharpening

Do not sharpen beyond 1/3 of the width of the blade. (See Figure 13).

-NOTE-

Dress the blade with a file. Using a wheel grinder may burn the blade. Check the balance of the blade. If blades are out of balance, vibration and premature wear can occur. See your authorized Scag Dealer for blade balance tools.

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 three (3) different positions for optimum performance.

C. 4" Position (factory setting, Velocity Plus Deck) -

baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck . (See Figure 17). Placing the baffle in the 4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout".

T o adjust the Custom-Cut Baffle height:

1. Place the cutter deck in the transport position.

2. Remove the hardware securing the Custom-Cut Baffle to the cutter deck. (See Figure 14).

-NOTE-

Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size.
