Shut the engine off and wait until the blades come to a complete stop before removing the grass catcher container. A. Mow only in daylight or when there is good artificial light. B. Watch for holes or other hidden hazards. 12. Never raise the cutter deck while the blades are rotating. C. Do not drive close to a drop-off, ditch, creek bank, or other hazard. 13. Always park the mower and/or start the engine on a level surface. Apply the parking brake to prevent the mower from moving when you are not in the operator’s position. E. Do not operate where conditions are slippery. WARNING DO NOT OPERATE WITHOUT DISCHARGE CHUTE, MULCHING KIT, OR ENTIRE GRASS CATCHER INSTALLED 5. The discharge chute must always be installed and in the down position on the side discharge cutter deck except when the mulching plate or Hurricane Mulch Kit are properly installed. 5 14. If the cutting blades should strike a solid object or the equipment should start to vibrate abnormally, stop the engine, disconnect the spark plug wires, 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. 15. 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. WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. 16. ALWAYS travel up or down the slope whenever possible. Never across the slope. WARNING: 2. Disconnect the spark plug wires from the spark plugs to prevent accidental starting of the engine when servicing, adjusting or storing the machine. 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. Under no circumstances should the machine be operated on slopes greater than 15 degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION. 3. To reduce potential fire hazard, keep the engine free of excessive grease, grass, leaves and accumulations of dirt. 4. Park the machine on level ground. Never allow untrained personnel to service the machine. 5. Disconnect battery or remove spark plug wires before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. CAUTION: DO NOT touch the engine or the muffler while the engine is running or immediately after stopping. These areas may be hot enough to cause a burn. 6. Use care when checking blades. Wrap the blades or wear gloves and use caution when servicing them. Only replace or sharpen blades. Never straighten or weld them. 17. Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. 18. Before leaving the operator’s position or leaving the mower unattended, move the right foot pedal into the neutral position, apply the parking brake, and move the blade engagement switch to OFF. Shut the engine OFF and remove the key. 7. Be sure the machine is in safe operating condition by keeping nuts, bolts, and screws tight. Check the blade mounting bolts and nuts frequently to be sure they are tightened. 19. Do not pass or stand on the grass discharge side of any mower with the engine running. Stop the cutter blades when another person approaches. 8. If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing and other parts of the body away from the cutter deck blades and other moving parts. 20. Never leave the machine running unattended. 9. Do not overspeed the engine by changing governor settings. To be sure of safety and accuracy, have an authorized dealer check maximum engine speed with a tachometer. MAINTENANCE AND STORAGE 1. If the mower must be tipped to perform maintenance or adjustment, remove the battery, drain the gasoline from the fuel tank and the oil from the crankcase. Use jack stands to support the machine when required. 10. The engine must be shut off before checking the oil or adding oil to the crankcase. 6 11. Allow the engine to cool before storing the mower in any enclosure such as a garage or storage shed. Make sure the fuel tank is empty if the machine is to be stored in excess of 30 days. Do not store the mower near any open flame or where gasoline fumes may be ignited by a spark. 3. Check the tires for proper pressure. Caster Wheels Flat Free Drive Wheels 12 psi Rear Steering Wheel 15 psi 12. Always store gasoline in a safety-approved, red container. 5. Check the safety switches for proper adjustment: 4. Check for loose hardware. Tighten as needed. * The engine should crank and start if the machine is in neutral, the PTO engagement switch is OFF and the parking brake is ON. 13. Be careful when servicing the battery as it contains acid, which is corrosive and could cause burns to skin and clothing. 6. Apply lubricant to all the grease fittings. Lubricant was applied at the factory. This is just a precautionary check to make sure that all the fittings have been lubricated. 14. Batteries release explosive gases when being charged or discharged. Keep batteries away from any source of sparks and/or flame. Charge batteries in an open, well ventilated area. 15. Make sure all hydraulic connections are tight and all hydraulic hoses and lines are in good condition before starting the machine. WARNING: Hydraulic fluid is under high pressure. Keep body and hands away from pinholes or nozzles that eject hydraulic fluid under high pressure. If you need service on your hydraulic system, please see your authorized Scag dealer. If hydraulic fluid is injected into the skin, it must be surgically removed within a few hours by a doctor or gangrene may result. INITIAL RUN-IN PROCEDURES (FIRST DAY OF USE OR APPROXIMATELY 10 HOURS) 1. Check the belts for proper tension at 2, 4 and 8 hours. Adjust as needed. (See Belt Tension, page 10). 2. Check the neutral adjustment. (See Adjustments, page 9) 7 MOWER OPERATION -NOTEWhen the 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 cutter blades come up to speed. For best equipment life, engage the clutch with the engine at 3/4 throttle, not under full load. 1. Read and understand the safety instructions before attempting to operate this machine. 2. Before starting the engine: * Check the oil level in the engine and the hydraulic reservoir. * Fill the fuel tank with clean, fresh, lead-free gasoline. * Open the fuel valve on the bottom of the fuel tank. WARNING: If you are not familiar with the operation of the hydrostatic drive, practice turning and maneuvering before engaging the cutter blades. -NOTEUse gasoline with an octane rating no less than 87 and a maximum of 10% ethanol. 6. Release the parking brake. Depress the right foot pedal at the toe end to drive forward (See Figure 1) or depress the pedal at the heel end to drive in reverse. (See Figure 2) * The right hand foot pedal must be in the NEUTRAL position. * The blade clutch switch must be in the OFF position. * The parking brake must be ON. -NOTEThe left side operator presence pedal must be depressed for operation. 3. Start the engine: * Choke as required. If the engine is cold, pull the choke knob out. When the engine starts, slowly push the choke in. If the engine stalls, repeat the above operation. When the engine is warm, choking may not be necessary. 4. Depress the left hand operator presence pedal. sgb002 5. Engage the cutter blades by pulling the blade clutch switch into the ON position. Push the switch to the OFF position to disengage the cutter blades. Depress Toe End of Pedal Figure 1. Forward Operation PULL UP TO ENGAGE PUSH DOWN TO DISENGAGE 390S0138 8 ADJUSTMENTS PARKING BRAKE Minor brake adjustments can be made by loosening the top nut on both brake cables (see Figure 4). Back the nuts off approximately 1/4". While pulling one cable downward, tighten the bottom nut on the cable until it touches the bottom of the brake cable mount. Tighten both the top and bottom nuts to lock the cable in place. Repeat the above steps for the second brake cable. Make sure that both cables are adjusted evenly so that the brakes do not cause the mower to pull to the left or right. SGB003 Depress Heel End of Pedal Figure 2. Reverse Operation -NOTEThis is a minor brake adjustment. If the brakes do not function properly after this adjustment, see your Scag Service Dealer before operating your mower. 7. When driving over curbs, disengage the cutter blades and raise the cutter deck to clear the curb. Drive forward over the curb. After the curb is clear, lower the cutter deck back to normal operating position. Be sure to leave slack in the cable after lowering the cutter deck. 8. To "freewheel" or move the machine around without the engine running, rotate the dump valve lever located on the left rear of the engine deck to the freewheel position (See Figure 3). The lever must be returned to the drive position to operate the machine. DUMP VALVE FREE WHEEL Adjust Nuts DRIVE SGB028 Figure 4. Parking Brake Adjustment NEUTRAL ADJUSTMENT 1. Set the engine deck up on jack stands so the wheels are free to rotate. SGB006 2. Block the caster wheels to prevent an accident should the machine fall off the jack stands. Figure 3. Dump Valve Location -NOTETo prevent damage to the hydraulic system, do not exceed 1MPH when moving the machine in the freewheel postion. 3. Start the engine and determine if the drive wheels rotate. 9 5. Check the adjustment of the right foot control pedal for full forward speed. The pedal should rest on the foot plate when the pump is stroked in the full forward position. To make an adjustment, disconnect the ball joint from the pedal arm and loosen the jam nut (See Figure 6). Place the foot control pedal forward against the foot rest and adjust the ball joint on the rod until the stud aligns with the hole in the arm. Bolt the ball joint to the arm and tighten the jam nut. If the drive wheels consistently rotate when foot pedal control is in neutral, go to step 4. If the drive wheels inconsistently rotate, i.e. drive wheels sometimes rotate and sometimes do not when foot pedal is not depressed, then check neutral adjustment bolt for "zero free play" in neutral control spring. -NOTEIf there is free play in the foot pedal have your SCAG servicing dealer inspect the machine and repair it as needed. 4. If the drive wheels rotate in the forward travel direction, turn the adjustment bolt clockwise until the tire rotation stops. If the drive wheels rotate in the backward travel direction, turn the adjustment bolt counter-clockwise until the tire rotation stops (See Figure 5). Jam Nut Ball Joint SGB030 Figure 6. Foot Control Pedal Adjustment 6. Start the engine. The wheels should rotate only when the foot control pedal is depressed. BELT TENSION CAUTION: Stop engine and remove the key from the ignition before making any adjustments. Wait for all moving parts to come to a complete stop before beginning work. Neutral Control Spring 9/16" Socket SGB029 -NOTEThe Hydro Drive Belt is spring-loaded and does not require adjustment. Figure 5. Neutral Adjustment To adjust cutter deck drive and blade belts: 1. Remove belt cover. 10 2. To adjust cutter deck drive belt: Adjust the nut so that the belt moves 1/2" with 10 pounds of pressure. (See Figure 7). Adjust the tension by tightening or loosening the nut on the J-bolt. (See Figure 9). Nut "J" Bolt End Of L-Shaped Bracket Nut Deck Belt "J" Bolt Washer Washer Belt SGB044 SGB031 Figure 9. Blade Belt Tension Adjustment Figure 7. Cutter Deck Drive Belt Tension 4. Replace the belt covers. 3. To adjust blade drive belt: Using a belt tension gauge, check the belt tension so that the belt moves 1/2" with 10 pounds of pressure. (See Figure 8). 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 Dealer for belt adjustment. CUTTER DECK ADJUSTMENTS Due to the many conditions that exist, it is difficult to suggest a setting that will work for every lawn. There are, however, two adjustments that should be made on the cutter deck: pitch and height. PITCH is the angle of the blades (comparing front to rear). Use of Tension Gauge HEIGHT is the nominal distance that the blade is off the ground. This measurement is made with the blades pointed side to side and distance is measured between cutting tip and ground. sgb007 Figure 8. Blade Drive Belt Tension Check 11 Adjusting the blade height can be done by moving any number of the five smaller spacers on the blade mounting bolts to the top or to the bottom of the spindle shaft. All blades should be positioned equally (See Figure 10). The unit is shipped with one spacer on top of spindle and four underneath (See Figure 10). There are three positions for mounting the cutter deck (See Figure 11). For cutting in the lowest position, mount the cutter deck in the top hole (A). For cutting in the highest position, mount the deck in the lowest hole (C). Setting the cutter deck height will be determined by the type of cutting conditions. This adjustment does not affect blade pitch. A B Hex Nut-Torque to 75 Lb-Ft Cutter Blade Spacer 1/4" C Cutter Deck Spindle Shaft SGB032 Figure 11. Cutter Deck Height Adjustment Spindle Assembly Caster spacers also can be repositioned to change the cutting heights and to change the pitch of the deck (See Figure 12). Hex Head Bolt / Nut Cutter Blade Spacers1/4" To adjust the caster spacers, raise the deck and remove the pin and caster wheel. Reposition the caster spacers as needed, then replace the caster, top spacers and pin. Make the same adjustments on the other caster wheel. Washer Cutter Blade To adjust the blade height, move any number of the five 1/4" thick spacers on the blade mounting bolts to the top of the spindle shaft or below the spindle shaft. Hex Head Bolt Figure 10. Cutter Blade Adjustment Pin -NOTEFor best results, keep the cutter deck high in relation to the engine deck and the blades low in the cutter deck; ie. 4 or 5 spacers below the spindle shaft. Spacers Additional range to the cutting height can be achieved by repositioning the cutter deck in relationship to the engine deck. This adjustment also affects the pitch of the deck. 2002SGB005 Figure 12. Repositioning Spacers 12 CUTTER BLADES CAUTION: Blades have a sharp cutting edge. Wear protective gloves or wrap blades with protective material when removing, sharpening and installing blades. Angle Blade Back X Do Not Cut In 30 X Must NOT Exceed 1/3 Blade Width SGB033 Figure 13. Blade Sharpening Do not sharpen beyond 1/3 of the width of the blade. (See Figure 13). A. 3" Position - baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. (See Figure 15). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass. B. 3-1/2" Position (factory setting, Advantage Deck) baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. (See Figure 16). For general purpose cutting, place the Custom-Cut Baffle in the 3-1/2" position. This gives the best mix of cutting performance in all types of grass. C. 4" Position (factory setting, Velocity Plus Deck) baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck . (See Figure 17). Placing the baffle in the 4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout". To adjust the Custom-Cut Baffle height: -NOTEDress the blade with a file. Using a wheel grinder may burn the blade. Check the balance of the blade. If blades are out of balance, vibration and premature wear can occur. See your authorized Scag Dealer for blade balance tools. 1. Place the cutter deck in the transport position. 2. Remove the hardware securing the Custom-Cut Baffle to the cutter deck. (See Figure 14). 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 three (3) different positions for optimum performance. -NOTEHardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size. MOUNTING HARDWARE MOUNTING HARDWARE 2004 CCB Figure 14. Custom-Cut Baffle 13 3. Move the Custom-Cut Baffle to desired position.

This warranty is limited to the original purchaser and is not transferable. Proof of purchase will be required by the dealer to substantiate any warranty claims.

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, 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 two (2) 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 two 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.
