  • Page 9: Safety Information

    Section 2 INTRODUCTION Your mower is only as safe as the operator. Carelessness or operator error may result in serious bodily injury or death. Hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of the personnel involved in the operation, transport, maintenance and storage of the equipment.

  • Page 10: Operation Considerations

    DO NOT allow children to ride or play on the machine, it is not a toy. Clear the area to be mowed of objects that could be picked up and thrown by the cutter blades. DO NOT carry passengers. DO NOT operate the machine under the influence of alcohol or drugs.
  • Page 11 Section 2 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. Stay two cut widths away from slopes, drop offs, ditches and retaining walls. To prevent tipping or loss of control, start and stop smoothly, avoid unnecessary turns and travel at reduced speed.

  • Page 12: Roll-Over Protection System

    Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. NEVER leave the machine running unattended. ROLL-OVER PROTECTION SYSTEM WARNING Keep the roll bar in the raised and locked position and the seat belt securely fastened during operation.
  • Page 13 Section 2 WARNING Failure to properly inspect and maintain the seat belt can cause serious injury or loss of life. Check the full length of the seat belt webbing for cuts, wear, fraying, dirt and stiffness. See Figure 2-3. Check the seat belt webbing in areas exposed to ultra violet rays from the sun or extreme dust or dirt.

  • Page 14: Maintenance Considerations & Storage

    MAINTENANCE CONSIDERATIONS & STORAGE Never make adjustments to the machine with the engine running unless specifically instructed to do so. If the engine is running, keep hands, feet, and clothing away from moving parts. Disengage drives, lower implement, set parking brake, stop engine and remove key or disconnect spark plug wire to prevent accidental starting of the engine when servicing or adjusting the machine.

    Hourmeter (Figure 4-1). Indicates the number of hours the engine has been operated. It only operates when the engine is running. Has preset maintenance reminders for engine and hydraulic system oil changes. Will start flashing scheduled maintenance 2 hours before preset time and continue flashing until 2 hours after.

  • Page 21: Initial Run-In Procedures

    Section 4 INITIAL RUN-IN PROCEDURES FIRST DAY OF USE OR APPROxIMATELY 20 HOURS Check all belts for proper alignment and wear at 2, 4 and 8 hours. Change the engine oil and oil filter after the first 20 hours of operation. (See Section 7.4.) Check hydraulic oil level in reservoir.

  • Page 22: Engaging The Deck Drive (Cutter Blades)

    - 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 4.1, items 13 - 15, on page 14 for cutter deck raising descriptions.) REvERSE TRAvEL CAUTION...

  • Page 23: Hillside Operation

    Section 4 HILLSIDE OPERATION 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.

  • Page 24: Moving Mower With Engine Stopped

    4.11 MOvING MOWER WITH ENGINE STOPPED To “free-wheel” or move the mower around without the engine running, rotate the dump valve levers counter- clockwise. See Figure 4-4. Disengage the parking brake and move the mower by hand. When the machine is in the desired position, engage the parking brake and rotate the levers clockwise until they stop.

  • Page 25: Adjusting The Steering Levers

    Section 4 Insert the lanyard pin into the cutting height index at the desired cutting height. Push forward on the deck lift foot lever, hold in place and pull back on the deck release lever. See Figure 4-6. Slowly release the foot pedal.

  • Page 26: Towing (Optional Hitch Accessory)

    4.16 TOWING (OPTIONAL HITCH ACCESSORY) NEVER allow children or others in or on towed equipment. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point. Follow manufacturer's recommendations for weight limit for towed equipment.

  • Page 30: Adjustments

    PARKING BRAKE ADJUSTMENT WARNING Do not operate the mower if the parking brake is not operable. Possible severe injury could result. The parking brake linkage should be adjusted whenever the parking brake lever is placed in the “ENGAGE” position and the parking brake will allow the mower to move. If the following procedures do not allow you to engage the parking brake properly, contact your Scag dealer for further brake adjustments.

  • Page 31: Travel Adjustments

    Section 6 TRAvEL ADJUSTMENTS Neutral or tracking adjustments will need to be made if: A. The steering control levers are in the neutral position and the machine creeps forward or backward. See Neutral Adjustment on page 25 (next procedure). B. The steering control levers are in the full forward position and the mower pulls to one side or the other when traveling in a forward direction.

  • Page 32: Throttle Control And Choke Adjustments

    Actuate the steering control levers forward and reverse several times and return them to the neutral position. Check that the drive wheels remained in neutral and readjust if necessary. Check that the steering control levers hit the stop before the pumps reach full stroke. Adjust as needed.

  • Page 33: Belt Alignment

    Section 6 BELT ALIGNMENT Belt alignment is important for proper performance of your Scag mower. If you experience frequent belt wear or breakage, see your authorized Scag service center for belt adjustment. 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.

  • Page 34: Custom-Cut Baffle Adjustment

    - NOTe - To prevent the cutter deck from teetering, all four (4) cutter deck hanging chains must have tension on them. If all four chains do not have tension on them and the deck teeters, you must readjust the cutter deck as outlined in the procedures above.
  • Page 35 Section 6 C. 4-3/4" or 5-1/4" Position - (See Figure 6-9). 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: Place the cutter deck in the transport position. Remove the hardware securing the Custom-Cut Baffle to the cutter deck.

  • Page 36: Electric Clutch Adjustment

    ELECTRIC CLUTCH ADJUSTMENT 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 assist in stopping blade rotation when the PTO is switched off or the operator presence circuit is interrupted.

    FILLER NECK INSERT FUEL LEVEL Figure 7-6. C.A.R.B. / ePA Phase 3 Fuel Level To avoid personal injury or proper ty damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Extinguish all cigarettes, cigars, pipes and other sources of ignition.

  • Page 43: Battery

    Section 7 - NOTe - In extremely dusty conditions it may be necessary to check the element once or twice daily to prevent engine damage. Unhook the clamps securing the air cleaner cover to the air filter canister. Remove the air cleaner cover and set aside.

  • Page 44: Drive Belts

    WARNING BATTERIES PRODUCE ExPLOSIvE GASES. Charge the battery in a well ventilated space so gases produced while charging can dissipate. 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).

  • Page 45: Tires

    Section 7 Angle Blade Back Do Not Cut In Figure 7-8. Blade Sharpening 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.
