2.3 BEFORE OPERATION CONSIDERATIONS

1. NEVER allow children to operate this riding mower. Do not allow adults to operate this machine without proper instructions.

2. DO NOT mow when children and/or others are present.

3. Clear the area to be mowed of objects that could be picked up and thrown by the cutter blades.

4. DO NOT carry passengers.

Section 2

5. DO NOT wear loose fitting clothing that could get tangled in moving parts. Do not operate the machine wearing shorts; always wear adequate protective clothing including long pants. Wearing safety glasses, safety shoes and a helmet is advisable and is required by some local ordinances and insurance regulations.

6. Operator hearing protection is recommended, particularly for continuous operation of the mower. Wear suitable hearing protection. Prolonged exposure to loud noise can cause hearing impairment or loss.

7. Keep the machine and attachments in good operating condition. Keep all shields and safety devices in place. If a shield, safety device or decal is defective or damaged, repair or replace it before operating the machine.

WARNING:

This machine 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 operator is seated in the seat, the deck drive is disengaged, and the speed control is placed in the neutral position with the parking brake applied. The system also shuts off the engine if the operator leaves the seat with the mower running and the speed control is not in the neutral postion with the parking brake applied. It will also shut off the engine if the hopper is raised with the cutter deck drive engaged. Never operate equipment with the interlock system disconnected or malfunctioning.

8. Be sure interlock switches are functioning correctly.

9. Fuel is flammable; handle with care. Fill fuel tank outdoors. Never fill indoors. Use a funnel or spout to inhibit spillage. Clean up any spillage before starting the engine.

10. DO NOT add fuel to a running or hot engine. An explosion could occur. Allow engine to cool for several minutes before adding fuel.

11. Keep flammable objects (cigarettes, matches, etc.), open flames and sparks away from the fuel tank and fuel container.

12. Equipment must comply with the latest requirements per ANSI J137 and/or ANSI S279 when driven on public roads.

-NOTE-

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

13. DO NOT operate without a chute deflector installed; keep the deflector in lowest possible position.

14. Check the blade mounting bolts at frequent intervals for proper tightness.

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

2.4 OPERATION CONSIDERATIONS

4.2 SAFETY INTERLOCK SYSTEM

The mower is equipped with a safety interlock system that prevents the engine from starting unless the deck drive is disengaged and the speed control is in neutral and the parking brake is engaged. The interlock system shuts off the engine if the operator leaves the seat with the speed control in the neutral position and the parking brake is not engaged and/or the cutter blades are engaged. It will also shut the engine off if the cutter deck drive is engaged and the hopper is raised.

WARNING:

Section 4

3. If the engine is cold, adjust the engine choke as needed.

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.

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

1. Check all belts for proper alignment and wear after the initial 2, 4, and 8 hours of operation. The belt systems are self adjusting therefore tension adjustment is not necessary.

2. Change the engine oil and oil filter after the first 5 hours of operation. (See Section 7.4.)

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

7.3.)

4. Check for loose hardware. Tighten as needed.

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

4. Adjust engine throttle control to about half engine speed.

5. 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.

6. Allow engine to warm before operating the mower.

4.5 GROUND TRAVEL AND STEERING

-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.

6. Check tire pressure. Inflate tires if necessary.

4.4 ST ARTING THE ENGINE

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.

1. Be sure the fuel shutoff valve, located on top of the left fuel tank, is completely open. (See Section 7.4)

2. Sit in the operators seat and place the speed control in the neutral position and engage the parking brake.

-IMPORTANT-

Start practice with a slow engine speed and slow forward travel.

Do not push the steering control levers forward when traveling forward. They are only used to steer the mower and to travel in reverse by pulling back on the levers.

Learn to operate the mower with the left hand on the steering levers and the right hand on speed control as shown in Figure 4-4. Using both hands on the steering levers often causes overcontrol.

Learn to feather the steering controls to obtain a smooth operating action. Jerky movements tend to place extreme force on the drive pumps and axles, as well as damage the lawns.

Practice operating the mower until you can make it go exactly where you are aiming.

Section 4

In case of an emergency, such as loss of control, stop the mowers movement by quickly pulling the forward speed control lever to the neutral position.

Forward Tr avel

-NOTE-

Use one hand on both steering levers as shown in Figure 4-4 to minimize overcontrol.

To travel forward with the mower, move the speed control lever forward. Do not push the steering control levers forward as they are used only for steering the mower left or right. When the speed control is moved forward, the mower will travel forward at the speed the control lever is set at. To increase the speed, push the control lever forward and to decrease the speed, pull the control lever back. It is not necessary to hold the speed control in position, since a friction system holds the lever in position.

To stop the forward travel, pull the speed control lever back to the neutral position.

To steer the mower left while traveling forward, pull the left steering lever back. The further the lever is pulled back, the sharper the mower will turn left.

To steer the mower right while traveling forward, pull the right steering control lever back. The further the lever is pulled back, the sharper the mower will turn right.

-NOTE-

Smooth operation of the steering levers will produce a smooth mower operation. While learning the operation of the steering controls, keep the travel speed low.

-IMPORTANT-

Do not travel forward over a curb. The mower will hang up on the curb. Tilt the deck and travel backwards over the curb at a 45 degree angle. (See section 4.15 for cutter deck tilting instructions)

Reverse Travel

Figure 4-4 Hands On Controls

SCR 2K HOC

CAUTION:

Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur.

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.

To travel in reverse, pull both handles all the way back. Keep the travel speed low while traveling in reverse.

-NOTE-

The mower will not travel straight in reverse. Slight adjustments must be made using the steering controls.

Section 4

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 sharper 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 sharper the mower will turn right.

To stop the reverse travel, place the speed control lever in the neutral position and allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake and remove the ignition key.

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.

2. Engage the deck drive by pulling out on the yellow switch, located on the instrument panel, (Figure 4-6) to the engage position.

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

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

4.7 HILLSIDE OPERATION

WARNING:

T o 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. A void 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 reduces traction and steering control.

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

PUSH DOWN TO DISENGAGE

STT99CES

Figure 4-5 Cutter Engage Switch

-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 a normal condition.

3. Keep tires properly inflated.

4. Always travel up or down the slope, whenever possible; NEVER across the slope. (See Figures 4-6 and 4-7.)

every day of operation.

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

4.10 HOPPER, MULCH or SIDE DISCHARGE OPERA TION

When mowing with the cutting deck setup for rear discharge into the hopper, the blower belt must be installed. A control lever located on the left side of the tractor (Figure 4-8) will release tension on the idler pulley to allow the belt to be installed (grass catching operation) or removed (mulching or side discharge operations). The cutter deck must also be adapted to the type of cutting that the operator is attempting to perform.

1. Place the speed control in the neutral position.

2. Slow the engine to idle speed.

3. Engage the parking brake.

4. 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.

-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.

Grass Catching Operation

CAUTION:

Never leave grass clippings in the hopper after mowing. Wet or damp clippings will generate heat as they decompose which may cause spontaneous combustion to occur.

1. With the hopper lowered, engage the deck drive. When the deck drive is engaged, the grass delivery spout, which is designed to distribute the grass clippings through the inside of the hopper, will begin to oscillate. If the spout does not oscillate, do not use the grass catcher. Use the side discharge and then have the oscillating spout system repaired.

Section 4

Lock Pin and Latch Plate

SCR 2K TGO

-NOTE-

The mower has an interlock switch that will prevent the mower from starting if the hopper is in the raised position. This interlock switch will also shut the engine off if the hopper is raised while the engine is running and the deck drive is engaged.

2. Proceed to mow the lawn until the hopper is full. If your mower is not equipped with the optional hopper fill alarm to tell you when the hopper is full, check the hopper frequently when first using the grass catcher. After operating with the grass catcher for awhile, experience will tell you when the hopper is full.

4. When dumping the hopper into a disposal area:

A. Disengage the deck drive.

WARNING:

Never operate the grass catcher with the hopper back door open. Objects can be thrown out the spout of the hopper with a force that can cause injury to bystanders or property damage.

4.12 MOVING MOWER WITH ENGINE STOPPED

To free-wheel or move the mower around without the engine running, place the dump valve handle in the FREE-WHEEL position (Figure 4-2). Disengage the parking brake and move the mower by hand. The lever must be returned to the DRIVE position to drive the mower.

4.13 RECOMMENDA TIONS FOR MOWING

1. Do not mow with dull blades. A dull blade will tear grass, resulting in poor lawn appearance and requiring extra power.

2. 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.

4.14 ADJUSTING CUTTING HEIGHT

The mower deck can be adjusted from a height of 1 1/2inches to 5-inches at 1/2-inch intervals. To adjust the cutting height:

WARNING:

Do not adjust the cutting height with the mower blades rotating. Shut off the engine and remove the ignition key . Bodily injury could occur from the rotating blades.

1. Shut off the engine and remove the ignition key.

Remove Hair Pins

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 system clean.

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.

6. Use a slow travel speed for trimming purposes.

7. Operate the engine at or near 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.

Deck Height Adjustment Pin

7.7 BATTERY

A. Checking Electrolyte Level and Cleaning Battery

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.

WARNING:

Lead-acid batteries produce flammable and explosive gases. T o 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.

For any air cleaner, the operating environment dictates the air cleaner service periods. Inspect and clean the air cleaner element after every 100 hours of operation or biweekly, whichever occurs first and replace the element if required.

-NOTE-

In extremely dusty conditions it may be necessary to check the element once or twice daily to prevent engine damage.

1. Remove the wing nut securing the air cleaner cover to the engine. Remove the air cleaner cover and set aside.

2. Remove the nut securing the clamping plate and the air cleaner to the engine. Remove the clamping plate and set aside. Remove the air cleaner and inspect.

3. Clean or replace the air cleaner and foam precleaner as neccessary.

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.

WARNING:

Section 7

B. Charging the Battery

Refer to the battery chargers manual for specific instructions.

EXTERNAL CONTACT — Flush with water.

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. Tilt the seat forward to access the battery.

2. Remove the battery cell caps. Visually inspect electrolyte level in the cells. If electrolyte is 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.

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.

-IMPORTANT-

Do not overfill the battery. Electrolyte will overflow through the vent tube onto parts of the machine, resulting in severe corrosion.

3. Clean the cable ends and battery posts with steel wool or a wire brush. Use a solution of baking soda and water to clean the battery. Do not allow the solution to enter the battery cells.

4. Tighten the cable connections securely and apply a light coat of silicone dielectric grease to the terminal connections to prevent corrosion.

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.

C. Jump Starting

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.

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.

Section 7

7.8 DRIVE BELTS

After the first 2, 4, 8 and 10 hours of operation, check for proper tension on all drive belts and check for any damage. Thereafter, check the belt tension after every 100 hours of operation or bi-weekly, whichever occurs first.

1. Check the belts for cracks, tears, and excessive wear. Replace any damaged belts.

7.9 CUTTER BLADES

A. Blade Inspection

1. Remove the ignition key before servicing the blades.

2. Tilt the mower deck and secure in place.

WARNING:

Never operate the cutter blades with the deck in the raised position because it is hazardous and damage to mower will result.

3. Check the blades for straightness. If the cutter blades appear bent, they will need to be replaced.

B. Blade Sharpening

-NOTE-

DO NOT sharpen the blades beyond 1/3 of the width of the blade.

1. Sharpen the cutting edge at the same bevel as the original. See Figure 7-8. Sharpen only the top of the cutting edge to maintain sharpness.

ANGLE BLADE BACK

DO NOT CUT IN

Figure 7-8 Blade Sharpening

2. Check the balance of the blade. If the blades are out of balance, vibration and premature wear can occur. See your authorized Scag dealer for blade balancing or special tools, if you choose to balance your own blades.

X MUST NOT EXCEED

1/3 BLADE WIDTH

390S0139

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.

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

C. Blade Replacement

1. Remove the ignition key and engage parking brake before replacing the blades.

2. Tilt the mower deck and secure in place with lock pin.

3. Secure the cutter blades to prevent them from rotating, (use the optional Blade Buddy tool, P/N 9212, to assist in securing the cutter blades), remove the nut from the blade attaching bolt. Remove the cutter blade, bolt and spacer from the spindle shaft.

4. To install the new blade, put the flat washer onto the blade bolt and slide the bolt into the hole in the cutter blade.

5. Install the spacer onto the blade bolt and insert the belt into the cutter spindle shaft.

Section 7

CAUTION:

-IMPORTANT-

Spindle blade bolts are left handed thread.

6. Install the hex nut to the blade bolt at the top of the cutter spindle. Secure the blades from rotating using a Blade Buddy and torque to 75 ft-lbs.

7.10 TIRES

Check the tire pressures after every 8 hours of operation or daily.

Caster Wheels ........................................ 25 PSI

Rear Wheel............................................. 25 PSI

Drive Wheels ......................................... 12 PSI

7.11 HOPPER

The hopper screen should be cleaned after every 8 hours of operation or daily, whichever occurs first. It may be necessary to clean the screen more frequently when cutting wet and/or dirty grass.

Cutter deck gearbox can reach high operating temperatures. Allow cutter deck gearbox to cool before servicing.

The fluid level in the cutter deck gearbox should be checked after every 100 hours of operation or bi-weekly, whichever occurs first.

1. Remove the ignition key and engage the parking brake.

2. Lift the foot plate up to gain access to the gearbox.

3. Clean and remove the check plug from the side of the gearbox. See Figure 7-9. Visually check the fluid level in the plug port. The fluid level must be up to the bottom of the plug port. If the fluid level is low, fill gearbox through the check plug port with EP 8090 gear oil. Install the check plug and tighten securely.

GEARBOX FLUID CHECK PLUG

1. Remove the hopper screen from the hopper.

2. Wash the screen using a water hose until all the screen holes are clean.

3. Install the cleaned screen in the hopper.

-IMPORTANT-

Do not use the hopper with the screen removed. Grass clippings will discharge from the hopper with the screen removed.

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 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.
