FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT • Read this manual completely as well as other manuals that came with your mower. • DO NOT operate on steep slopes. To check a slope, attempt to back up it (with the cutter deck down).
USE ONLY SCAG APPROvED ATTACHMENTS AND ACCESSORIES. Attachments and accessories manufactured by companies other than Scag Power Equipment are not approved for use on this machine. See Section 8, Paragraph 8-1. For pictorial clarity, some illustrations and figures in this manual may show shields, guards or plates open or removed.
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.
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.

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.
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.

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.
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.
Section 4 Fuse Holders (Figure 4-1). Two 20-amp fuses protect the mower’s electrical system. To replace fuses, pull fuse out of the socket and install a new fuse. Left Steering Control (Figure 4-1). the mower's left wheel when traveling forward or reverse.
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.
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.
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.
Section 4 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.
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.

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.
Section 6 NEUTRAL ADJUSTMENT Be sure the dump valve levers are in the run position and the steering control levers are in the neutral lock position. With an operator in the seat, start the engine and disengage the parking brake. Run the engine at full operating speed and check if the machine creeps forward or backwards.
A. Stop the machine and place the steering control levers in the neutral position. Loosen the lock nuts securing the ball joints at each end of the RH steering control rod. Rotate the control rod to lengthen the rod and tighten the lock nuts. This will cause the control rod to stroke the RH pump less, slowing down the RH wheel.
Section 6 CUTTER DECk PITCH The pitch of the cutter deck should be equal between the front and rear of the cutter deck for proper cutting performance. To check for proper deck pitch, be sure that the mower is on a flat, level surface and the tires are properly inflated.
Check the cutter deck cutting height by placing the lanyard pin in the 3" position on the cutting height index. Release the deck from the transport position and allow the deck to move to the 3" cutting height position. Check the measurement from the floor to the cutter blade tip.
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.

Section 7 DRIvE BELTS All drive belts are spring-loaded and self-tensioning, however after the first 2, 4, 8 and 10 hours of operation, the belts should be checked for proper alignment and wear. Thereafter, check the belts after every 40 hours of operation or weekly, whichever occurs first.
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. See Figure 7-8.
