INTRODUCTION SIGNAL WORDS Your mower was built to the highest standards in the industry. However, the prolonged life and maximum efficiency of your mower depends on you following the operating, maintenance and adjustment instructions in this manual. This symbol means “Attention! Become Alert! Your Safety is Involved!" The symbol is used with the following signal words to attract your attention to safety messages found on the decals and throughout this manual.
BEFORE OPERATING WHILE OPERA TING OPERATING 1. Know the controls and how to stop quickly. 1. Start the engine when the neutral latches are in the neutral lock position, the cutter blades are disengaged, the parking brake is on and the speed adjustment lever is in the neutral position. 2. Do not allow children to operate the machine. Do not allow adults to operate the machine without proper instruction. 2. Do not run the engine in a confined area without adequate ventilation.
14. Use only Scag approved riding attachments. 9. If the cutting blades should strike a solid object or the equipment should start to vibrate abnormally, stop the engine, disconnect the spark plug wire, and check immediately for the cause. Vibration is generally a warning of trouble. Check the machine for damaged or defective parts. Repair any damage before starting the engine or operating the cutter deck. Be sure the blades are in good condition and the blade bolts are tight.
9. Always store gasoline in a safety-approved, red container. MOWER OPERATION 1. Read and understand the safety instructions before attempting to operate this machine. 10. Be careful when servicing the battery as it contains acid, which is corrosive and could cause burns to skin and clothing. 2. Before starting the engine: * Check the oil level in the engine and the hydraulic reservoir. * Fill the fuel tank with clean, fresh, leadfree gasoline. * Open the fuel valve on the bottom of the fuel tank. 11.
-NOTEWhen 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 mower comes up to speed. For best equipment life, engage the clutch with the engine at 1/2 throttle, not under full load. WARNING: If you are not familiar with the operation of the hydrostatic drive and zero turn feature, practice turning and maneuvering with the hand controls before engaging the blades.
LOW CUT (1 3/4"- 3") -NOTEDue to initial belt stretch and to prevent the belt from slipping, check this adjustment after the first 2 hours, 4 hours and 8 hours of operation. MID RANGE (2 1/2"- 3 3/4") 3. Adjust the RH blade drive belt using a belt tension gauge. Adjust the belt so that the belt moves 1/2" with 10 pounds of pressure. Adjust the tension by tightening or loosening the J-bolt nut (See figure 3). HIGH CUT (3 1/4"- 4 1/2") 4. Replace the belt cover.
ANGLE BLADE BACK X DO NOT CUT IN X MUST NOT EXCEED 1/3 BLADE WIDTH 30 SC4O8G Figure 7. Blade Sharpening NEUTRAL ADJUSTMENT 1. Raise the drive wheels off the ground and block the caster wheels. 2. Remove the speed control spring and the steering control rod from the machine. (See figure 8) Steering Control Rod Bolts SC407G Spring Figure 6. Blade Spacers Bellcrank Handle SC160G Figure 8. Neutral Adjustment 3. Loosen the wing nut and let the speed adjustment bearing lever fall away from the cam.
3. Tighten the bearing securing the speed adjustment bearing lever and repeat on the opposite side. STEERING CONTROL ROD ADJUSTMENT 4. With the machine on a flat level surface, start the engine and place the speed adjustment lever into the speed that will most often be used. -NOTEThis adjustment is made to allow the steering control levers to be moved out of the neutral latch without engaging reverse. 1. Connect the steering control rods into the steering control levers on the handle.
