  • Page 7: 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 8: Operation Considerations

    If the operator(s) or mechanic(s) cannot read English or Spanish, it is the owner's responsibility to explain this material to them. DO NOT wear loose fitting clothing. Loose clothing, jewelry or long hair could get tangled in moving parts. Do not operate the machine wearing shorts; always wear adequate protective clothing including long pants.
  • Page 9 Section 2 When using any attachment, never direct the discharge of material toward bystanders or allow anyone near the machine while in operation. Before attempting to start the engine, with the operator in the seat, disengage power to the cutter deck, place the steering control levers in the neutral position and engage the parking brake.
  • Page 10: Roll-Over Protection System

    ROLL-OvER PROTECTION SYSTEM WARNING Keep the roll bar in the raised and locked position and the seat belt securely fastened during operation. Failure to do so could cause serious injury or loss of life. This mower has been designed for good traction and stability under normal mowing conditions.
  • Page 11 Section 2 It is recommended that the seat belt be inspected on a daily basis for signs of damage. Any seat belt system that shows cuts, fraying, extreme or unusual wear, significant discoloration due to UV exposure, dirt or stiffness, abrasion to the seat belt webbing, or damage to the buckle, latch plate, hardware or any other obvious problem should be replaced immediately.
  • Page 12: 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.

    OPERATING INSTRUCTIONS CAUTION Do not attempt to operate this mower unless you have read this manual. Learn the location and purpose of all controls and instruments before you operate this mower. CONTROLS AND INSTRUMENT IDENTIFICATION Before operating the mower, familiarize yourself with all mower and engine controls.
  • Page 17: Safety Interlock System

    Section 4 Hour meter (Figure 4-1). Indicates the number of hours the engine has been operated. It operates whenever 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 18: Starting The Engine

    STARTING 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. Be sure the fuel shutoff valve, located behind the operator's seat, is completely open.
  • Page 19: Engaging The Deck Drive (Cutter Blades)

    Section 4 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.
  • Page 20: Hillside Operation

    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 21: Moving Mower With Engine Stopped

    Section 4 4.11 MOvING MOWER WITH ENGINE STOPPED To “free-wheel” or move the mower around without the engine running, place the dump valve levers in the FREE- WHEEL position (Figure 4-4). Disengage the parking brake and move the mower by hand. The dump valve levers must be returned to the DRIVE position and torqued to 10ft/lbs to drive the mower.
  • Page 22: Adjusting The Height Adjust Pedal

    DECK RELEASE LEVER Figure 4-6. Deck Release Lever 4.14 ADJUSTING THE HEIGHT ADJUST PEDAL Position the seat to the desired location. While in the operator's position without the engine running, push down on the height adjust pedal to check for full function control. The height adjust pedal can be located in three (3) different positions for operator comfort and control.
  • Page 23: Towing (Optional Hitch Accessory)

    Section 4 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.

    Section 6 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.
  • Page 28: Travel Adjustments

    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. (Neutral Adjustment, See Page 26). 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 29: Throttle Control And Choke Adjustments

    Section 6 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.
  • Page 30: Belt Alignment

    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 31 Section 6 - 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 32 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.
  • Page 33: Electric Clutch Adjustment

    Section 6 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.
