Do not put hands or feet near rotating parts or under the machine. Keep clear of the discharge opening at all times. Only allow responsible adults, who are familiar with the instructions, to operate the machine. Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blades. Be sure the area is clear of bystanders before operating. Stop machine if anyone enters the area. Never carry passengers. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing. • • 3 Never direct discharged material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blades when crossing gravel surfaces. Do not operate machine without the entire grass catcher, discharge guard, or other safety devices in place and working. Slow down before turning. Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove keys before dismounting. Disengage blades when not mowing. Shut off engine and wait for all parts to come to a complete stop before cleaning the machine, removing the grass catcher, or unclogging the discharge guard. Operate machine only in daylight or good artificial light. Do not operate the machine while under the influence of alcohol or drugs. Watch for traffic when operating near or crossing roadways. Use extra care when loading or unloading the machine into a trailer or truck. Always wear eye protection when operating machine. Data indicates that operators, age 60 years and above, are involved in a large percentage of riding mower-related injuries. These operators should evaluate their ability to operate the riding mower safely enough to protect themselves and others from serious injury. Follow the manufacturer’s recommendation for wheel weights or counterweights. Keep machine free of grass , leaves or other debris build-up which can touch hot exhaust / engine parts and burn. Do not allow the mower deck to plow leaves or other debris which can cause build-up to occur. Clean any oil or fuel spillage before operating or storing the machine. Allow machine to cool before storage. SAFETY RULES • II. SLOPE OPERATION Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it. • Mow up and down slopes, not across. • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles. • Choose a low ground speed so that you will not have to stop or shift while on the slope. • Do not mow on wet grass. Tires may lose traction. Always keep the machine in gear when going down slopes. Do not shift to neutral and coast downhill. • Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope. • Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the machine to roll over. • Use extra care while operating machine with grass catchers or other attachments; they can affect the stability of the machine. Do no use on steep slopes. • Do not try to stabilize the machine by putting your foot on the ground. • Do not mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel is over the edge or if the edge caves in. • • Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine. Never allow children to operate the machine. Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child. IV. TOWING • • • • • Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point. Follow the manufacturer’s recommendation for weight limits for towed equipment and towing on slopes. Never allow children or others in or on towed equipment. On slopes, the weight of the towed equipment may cause loss of traction and loss of control. Travel slowly and allow extra distance to stop. V. SERVICE SAFE HANDLING OF GASOLINE To avoid personal injury or property 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. • Use only approved gasoline container. • Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling. • Never fuel the machine indoors. • Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or other appliances. • Never fill containers inside a vehicle or on a truck or trailer bed with plastic liner. Always place containers on the ground away from your vehicle when filling. III. CHILDREN Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them. • Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator. • Be alert and turn machine off if a child enters the area. • Before and while backing, look behind and down for small children. 4 SAFETY RULES • • • • Remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle. Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device. If fuel is spilled on clothing, change clothing immediately. Never overfill fuel tank. Replace gas cap and tighten securely. • • • • GENERAL SERVICE • • • • • • • • • • Never operate machine in a closed area. Keep all nuts and bolts tight to be sure the equipment is in safe working condition. Never tamper with safety devices. • • • Be sure the area is clear of bystanders before operating. Stop machine if anyone enters the area. Never carry passengers. Do not mow in reverse unless absolutely necessary. Always look down and behind before and while backing. Never carry children, even with the blades shut off. They may fall off and be seriously injured or interfere with safe machine operation. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine. Keep children out of the mowing area and in the watchful care of a responsible adult other than the operator. Be alert and turn machine off if a child enters the area. • • • • • 5 Check their proper operation regularly. Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage and remove any fuel-soaked debris. Allow machine to cool before storing. If you strike a foreign object, stop and inspect the machine. Repair, if necessary, before restarting. Never make any adjustments or repairs with the engine running. Check grass catcher components and the discharge guard frequently and replace with manufacturer’s recommended parts, when necessary. Mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them. Check brake operation frequently. Adjust and service as required. Maintain or replace safety and instruction labels, as necessary. Before and while backing, look behind and down for small children. Mow up and down slopes (15° Max), not across. Choose a low ground speed so that you will not have to stop or shift while on the slope. Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blades and proceed slowly straight down the slope. If machine stops while going uphill, disengage blades, shift into reverse and back down slowly. Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.

TO OPERATE MOWER Your tractor is equipped with an operator presence sensing switch. Any attempt by the operator to leave the seat with the engine running and the attachment clutch engaged will shut off the engine. You must remain fully and centrally positioned in the seat to prevent the engine from hesitating or cutting off when operating your equipment on rough, rolling terrain or hills. 1. Select desired height of cut. 2. Lower mower with attachment lift control. 3. Start mower blades by engaging attachment clutch control. TO STOP MOWER BLADES disengage attachment clutch control. The cutting height range is approximately 1-1/2" to 4-1/2". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending upon soil conditions, height of grass and types of grass being mowed. • The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate growth. • For best cutting performance, grass over 6 inches in height should be mowed twice. Make the first cut relatively high; the second to desired height. CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deflector shield in place. TO ADJUST GAUGE WHEELS Gauge wheels are properly adjusted when they are slightly off the ground when mower is at the desired cutting height in operating position. Gauge wheels then keep the deck in proper position to help prevent scalping in most terrain conditions. NOTE: Be sure tractor is on a flat level surface. 1. Lower mower and adjust mower to desired cutting height. 2. Remove retainer spring and clevis pin which secure each gauge wheel bar. 3. Lower gauge wheels to ground. Raise gauge wheels slightly to align holes in bracket and gauge wheel bar and insert clevis pin. Gauge wheels should be slightly off the ground. 4. Replace retainer spring into clevis pin. 5. Be sure all gauge wheels are in the same setting. IMPORTANT: Be sure to readjust gauge wheels if you change the cutting height of the mower deck. Attachment Clutch Switch Pull Out to “Engage” Attachemnt Lift Lever High Position Low Position Deflector Shield Push-In to “Disengage” REVERSE OPERATION SYSTEM (ROS) Your tractor is equipped with a Reverse Operation System (ROS). Any attempt by the operator to travel in the reverse direction with the attachment clutch engaged will shut off the engine unless ignition key is placed in the ROS "ON" position. Retainer Spring WARNING: Backing up with the attachment clutch engaged while mowing is strongly discouraged. Turning the ROS "ON", to allow reverse operation with the attachment clutch engaged, should only be done when the operator decides it is necessary to reposition the machine with the attachment engaged. Do not mow in reverse unless absolutely necessary. Clevis Pin 12 Transmission Engaged USING THE REVERSE OPERATION SYSTEM 1. Move motion control lever to neutral (N) position. 2. With engine running, turn ignition key counterclockwise to ROS "ON" position. 3. Look down and behind before backing. 4. Slowly move motion control lever to reverse (R) position to start movement. 5. When use of the ROS is no longer needed, turn the ignition key clockwise to engine "ON" position. ROS "ON" Position Transmission Disengaged NOTE: To protect hood from damage when transporting your tractor on a truck or a trailer, be sure hood is closed and secured to tractor. Use an appropriate means of tying hood to tractor (rope, cord, etc.). TOWING CARTS AND OTHER ATTACHMENTS Tow only the attachments that are recommended by and comply with specifications of the manufacturer of your tractor. Use common sense when towing. Too heavy of a load, while on a slope, is dangerous. Tires can lose traction with the ground and cause you to lose control of your tractor. Engine "ON" Position (Normal Operating) 02828 TO OPERATE ON HILLS WARNING: Do not drive up or down hills with slopes greater than 15° and do not drive across any slope. Use the slope guide provided at the back of this manual. • Choose the slowest speed before starting up or down hills. • Avoid stopping or changing speed on hills. • If stopping is absolutely necessary, push brake pedal quickly to brake position and engage parking brake. IMPORTANT: The motion control lever returns to neutral (N) position when the brake pedal is depressed. • To restart movement, slowly release parking brake and brake pedal. • Slowly move motion control lever to slowest setting. • Make all turns slowly. BEFORE STARTING THE ENGINE CHECK ENGINE OIL LEVEL The engine in your tractor has been shipped, from the factory, already filled with summer weight oil. 1. Check engine oil with tractor on level ground. 2. Unthread and remove oil fill cap/ dipstick; wipe oil off. Reinsert the dipstick into the tube and rest oil fill cap on the tube. Do not thread the cap onto the tube. Remove and read oil level. If necessary, add oil until “FULL” mark on dipstick is reached. Do not overfill. • For cold weather operation you should change oil for easier starting (See the oil viscosity chart in the Maintenance section of this manual). • To change engine oil, see the Maintenance section in this manual. TO TRANSPORT When pushing or towing your tractor, be sure to disengage transmission by placing freewheel control in freewheeling position. Freewheel control is located at the rear drawbar of tractor. 1. Raise attachment lift to highest position with attachment lift control. 2. Pull freewheel control out and into the slot and release so it is held in the disengaged position. • Do not push or tow tractor at more than two (2) MPH. • To re-engage transmission, reverse above procedure. ADD GASOLINE • Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline will increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. 13 • The attachments and ground drive can now be used. If the engine does not accept the load, restart the engine and allow it to warm up for one minute using the choke as described above. COLD WEATHER STARTING (50° F and below) 7. When engine starts, slowly push choke control in until the engine begins to run smoothly. Continue to push the choke control in small steps allowing the engine to accept small changes in speed and load, until the choke control is fully in. If the engine starts to run roughly, pull the choke control out slightly for a few seconds and then continue to push the control in slowly. This may require an engine warm-up period from several seconds to several minutes, depending on the temperature. NOTE: In extreme cold conditions, if engine will not start you may need to disengage the motion drive belt as follows: 1. Be sure parking brake is engaged. 2. Remove retainer spring from the drive belt tension handle to relieve belt tension. 3. Start engine and allow it to warm up for three (3) minutes. 4. Shut-off engine and engage parking brake. 5. Engage drive belt tension handle and replace the retainer spring. AUTOMATIC TRANSMISSION WARM UP Before driving the unit in cold weather, the transmission should be warmed up as follows: 1. Be sure the tractor is on level ground. 2. Place the motion control lever in neutral. Release the parking brake and let the brake slowly return to operating position. 3. Allow one minute for transmission to warm up. This can be done during the engine warm up period. • The attachments can be used during the engine warm-up period after the transmission has been warmed up and may require the choke control be pulled out slightly. NOTE: If at a high altitude (above 3000 feet) or in cold temperatures (below 32 F) the carburetor fuel mixture may need to be adjusted for best engine performance (see “TO ADJUST CARBURETOR” in the Service and Adjustments section of this manual). CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. IMPORTANT: When operating in temperatures below32°F(0°C), use fresh, clean winter grade gasoline to help insure good cold weather starting. CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. TO START ENGINE When starting the engine for the first time or if the engine has run out of fuel, it will take extra cranking time to move fuel from the tank to the engine. 1. Be sure freewheel control is in the transmission engaged position. 2. Sit on seat in operating position, depress brake pedal and set parking brake. 3. Move attachment clutch to disengaged position. 4. Move throttle control to fast position 5. Pull choke control out for a cold engine start attempt. For a warm engine start attempt the choke control may not be needed. NOTE: Before starting, read the warm and cold starting procedures below. 6. Insert key into ignition and turn key clockwise to start position and release key as soon as engine starts. Do not run starter continuously for more than fifteen seconds per minute. If the engine does not start after several attempts, push choke control in, wait a few minutes and try again. If engine still does not start, pull the choke control out and retry. WARM WEATHER STARTING (50° F and above) 7. When engine starts, slowly push choke control in until the engine begins to run smoothly. If the engine starts to run roughly, pull the choke control out slightly for a few seconds and then continue to push the control in slowly. 14 PURGE TRANSMISSION MOWING TIPS CAUTION: Never engage or disengage freewheel lever while the engine is running. To ensure proper operation and performance, it is recommended that the transmission be purged before operating tractor for the first time. This procedure will remove any trapped air inside the transmission which may have developed during shipping of your tractor. IMPORTANT: Should your transmission require removal for service or replacement, it should be purged after reinstallation before operating the tractor. 1. Place tractor safely on level surface with engine off and parking brake set. 2. Disengage transmission by placing freewheel control in disengaged position (See “TO TRANSPORT” in this section of manual). 3. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to slow position. Disengage parking brake. 4. Move motion control lever to full forward position and hold for five (5) seconds. Move lever to full reverse position and hold for five (5) seconds. Repeat this procedure three (3) times. NOTE: During this step there will be no movement of drive wheels. The air is being removed from hydraulic drive system. 5. Move motion control lever to neutral (N) position. Shutoff engine and set parking brake. 6. Engage transmission by placing freewheel control in engaged position (See “TO TRANSPORT” in this section of manual). 7. Sitting in the tractor seat, start engine. After the engine is running, move throttle control to half (1/2) speed. Disengage parking brake. 8. Slowly move motion control lever forward, after the tractor moves approximately five (5) feet, slowly move motion control lever to reverse position. After the tractor moves approximately five (5) feet return the motion control lever to the neutral (N) position. Repeat this procedure with the motion control lever three (3) times. Your transmission is now purged and now ready for normal operation. • Tire chains cannot be used when the mower housing is attached to tractor. • Mower should be properly leveled for best mowing performance. See “TO LEVEL MOWER HOUSING” in the Service and Adjustments section of this manual. • The left hand side of mower should be used for trimming. • Drive so that clippings are discharged onto the area that has already been cut. Have the cut area to the right of the tractor. This will result in a more even distribution of clippings and more uniform cutting. • When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished. • If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clippings. Make first cut relatively high; the second to the desired height. • Do not mow grass when it is wet. Wet grass will plug mower and leave undesirable clumps. Allow grass to dry before mowing. • Always operate engine at full throttle when mowing to assure better mowing performance and proper discharge of material. Regulate ground speed by selecting a low enough gear to give the mower cutting performance as well as the quality of cut desired. • When operating attachments, select a ground speed that will suit the terrain and give best performance of the attachment being used. 15 MAINTENANCE MAINTENANCE SCHEDULE FILL IN DATES AS YOU COMPLETE REGULAR SERVICE E E RS S AG RS RS US OU SON OR UR OU HOU H T O H A 0 S H SE RE 25 10 50 EE Y 8 R RY ERY ERY ERY FO OR E E F E V V V V V B SERVICE E E E E E BE H AC DATES Check Brake Operation Check Tire Pressure T R A C T 0 R Check Operator Presence and ROS Systems Check for Loose Fasteners 5 Sharpen/Replace Mower Blades 3 Lubrication Chart Check Battery Level 4 Clean Battery and Terminals Check Transaxle Cooling Check V-Belts Check Engine Oil Level Change Engine Oil (with oil filter) 1,2 Clean Air Filter 2 Clean Air Screen 2 Inspect Muffler/Spark Arrester Replace Oil Filter (If equipped) 1, 2 Clean Engine Cooling Fins maint_sch-tractore.ROS.e E N G I N E 1,2 Change Engine Oil (without oil filter) 2 Replace Spark Plug Replace Air Filter Paper Cartridge 2 Replace Fuel Filter 1 - Change more often when operating under a heavy load or in high ambient temperatures. 2 - Service more often when operating in dirty or dusty conditions. LUBRICATION CHART GENERAL RECOMMENDATIONS The warranty on this tractor does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain tractor as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your tractor. At least once a season, check to see if you should make any of the adjustments described in the Service and Adjustments section of this manual. • At least once a year you should replace the spark plug, clean or replace air filter, and check blades and belts for wear. A new spark plug and clean air filter assure proper air-fuel mixture and help your engine run better and last longer. ➀ Spindle Zerk ➀ Spindle Zerk ➀ Front Wheel Bearing zerk ➀ Front Wheel Bearing zerk ➀ Steering Sector Gear Teeth ➁ Engine ➀ Mandrel Zerks 02501 ➀General Purpose Grease ➁Refer to Maintenance “ENGINE” Section IMPORTANT: Do not oil or grease the pivot points which have special nylon bearings. Viscous lubricants will attract dust and dirt that will shorten the life of the self-lubricating bearings. If you feel they must be lubricated, use only a dry, powdered graphite type lubricant sparingly. BEFORE EACH USE Check engine oil level. Check brake operation. Check tire pressure. Check operator presence and ROS systems for proper operation. 5. Check for loose fasteners. 3 - Replace blades more often when mowing in sandy soil. 4 - Not required if equipped with maintenance-free battery. 5 - Tighten front axle pivot bolt to 35 ft.-lbs. maximum.

BLADE CARE For best results mower blades must be kept sharp. Replace bent or damaged blades. CAUTION: Use only a replacement blade approved by the manufacturer of your tractor. Using a blade not approved by the manufacturer of your tractor is hazardous, could damage your tractor and void your warranty. BLADE REMOVAL 1. Raise mower to highest position to allow access to blades. NOTE: Protect your hands with gloves and/or wrap blade with heavy cloth. 2. Remove blade bolt by turning counterclockwise. 3. Install new or resharpened blade with stamped "THIS SIDE UP" facing deck and mandrel assembly. IMPORTANT: To ensure proper assembly, center hole in blade must align with star on mandrel assembly. 4. Install and tighten blade bolt securely (45-55 Ft. Lbs. torque). IMPORTANT: Special blade bolt is heat treated. TRACTOR Always observe safety rules when performing any maintenance. BRAKE OPERATION If tractor requires more than five (5) feet to stop at highest speed in highest gear on a level, dry concrete or paved surface, then brake must be checked and adjusted. (See “TO ADJUST BRAKE” in the Service and Adjustments section of this manual). TIRES • Maintain proper air pressure in all tires (See “PRODUCT SPECIFICATIONS” section of this manual). • Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber. • Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage. NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer. Tire sealant also prevents tire dry rot and corrosion. OPERATOR PRESENCE SYSTEM AND REVERSE OPERATION SYSTEM (ROS) Be sure operator presence and reverse operation systems are working properly. If your tractor does not function as described, repair the problem immediately. • The engine should not start unless the brake pedal is fully depressed, and the attachment clutch control is in the disengaged position. CHECK OPERATOR PRESENCE SYSTEM • When the engine is running, any attempt by the operator to leave the seat without first setting the parking brake should shut off the engine. • When the engine is running and the attachment clutch is engaged, any attempt by the operator to leave the seat should shut off the engine. • The attachment clutch should never operate unless the operator is in the seat. ROS "ON" Position Blade Blade Bolt (Special) Mandrel Assembly Star Center Hole TO SHARPEN BLADE NOTE: We do not recommend sharpening blade - but if you do, be sure the blade is balanced. Care should be taken to keep the blade balanced. An unbalanced blade will cause excessive vibration and eventual damage to mower and engine. • The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower. Engine "ON" Position (Normal Operating) 02828 17 • To check blade balance, you will need a 5/8" diameter steel bolt, pin, or a cone balancer. (When using a cone balancer, follow the instructions supplied with balancer.) NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not. • Slide blade on to an unthreaded portion of the steel bolt or pin and hold the bolt or pin parallel with the ground. If blade is balanced, it should remain in a horizontal position. If either end of the blade moves downward, sharpen the heavy end until the blade is balanced. 5/8” Bolt or Pin Blade Center Hole BATTERY Your tractor has a battery charging system which is sufficient for normal use. However, periodic charging of the battery with an automotive charger will extend its life. • Keep battery and terminals clean. • Keep battery bolts tight. • Keep small vent holes open. • Recharge at 6-10 amperes for 1 hour. NOTE: The original equipment battery on your tractor is maintenance free. Do not attempt to open or remove caps or covers. Adding or checking level of electrolyte is not necessary. TO CLEAN BATTERY AND TERMINALS Corrosion and dirt on the battery and terminals can cause the battery to “leak” power. 1. Remove terminal guard. 2. Disconnect BLACK battery cable first then RED battery cable and remove battery from tractor. 3. Rinse the battery with plain water and dry. 4. Clean terminals and battery cable ends with wire brush until bright. 5. Coat terminals with grease or petroleum jelly. 6.

INTERLOCKS AND RELAYS Loose or damaged wiring may cause your tractor to run poorly, stop running, or prevent it from starting. • Check wiring. See electrical wiring diagram in the Repair Parts section. TO REPLACE FUSE Replace with 30 amp automotive-type plug-in fuse. The fuse holder is located behind the dash. TO REMOVE HOOD AND GRILL ASSEMBLY 1. Raise hood. 2. Unsnap headlight wire connector. 3. Stand in front of tractor. Grasp hood at sides, tilt toward engine and lift off of tractor. 4. When replacing hood, be sure to reconnect the headlight wire connector. Hood Headlight Wire Connector Hex Bolt Positive (Red) Cable Negative (Black) Cable 27 1. Be sure you have a clean air filter and the throttle control cable is adjusted properly (see above). 2. Start engine and allow to warm for five minutes. Make adjustments with engine running and shift/motion control lever in neutral (N) position. 3. Idle speed setting - With throttle control lever in slow position, engine should idle at 1750 RPM. If engine idles too slow or fast, turn idle speed adjusting screw in or out until correct idle is attained. 4. Idle fuel needle setting - With throttle control lever in slow position, turn idle fuel adjustment needle in (clockwise) until engine begins to die and then turn out (counterclockwise) until engine runs rough. Turn needle to a point midway between those two positions. 5. Recheck idle speed. Readjust if necessary. ENGINE Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized engine manufacturer's service outlet. TO ADJUST THROTTLE CONTROL CABLE The throttle control has been preset at the factory and adjustment should not be necessary. Check adjustment as described below before loosening cable. If adjustment is necessary, proceed as follows: 1. With engine not running, move throttle control lever from slow to choke position. Slowly move lever from choke to fast position. 2. Check to see if hole in throttle lever and hole in speed control bracket are aligned. 3. If holes are not aligned, loosen cable clamp screw and align the holes by inserting a pencil or a 1/4" drill bit through both holes. 4. Pull throttle cable up to remove slack and tighten cable clamp screw. Remove alignment pencil or drill bit. TO ADJUST CARBURETOR The carburetor has been preset at the factory and adjustment should not be necessary. However, minor adjustment may be required to compensate for differences in fuel, temperature, altitude or load. If the carburetor does need adjustment, proceed as follows: In general, turning the adjusting needles in (clockwise) decreases the supply of fuel to the engine giving a leaner fuel/air mixture. Turning the adjusting needles out (counterclockwise) increases the supply of fuel to the engine giving a richer fuel/air mixture. IMPORTANT: Damage to the needles and seats in carburetor may result if turned in too tight. NOTE: The carburetor on this engine is low emission. It is equipped with an idle fuel adjusting needle with a limiter cap, which allows some adjustment within the limits allowed by the cap. Do not attempt to remove the limiter cap. The limiter cap cannot be removed without breaking the adjusting needle. ACCELERATION TEST 6. Move throttle control lever from slow to fast position. If engine hesitates or dies, turn idle fuel adjusting needle out (counterclockwise) 1/8 turn. Repeat test and continue to adjust, if necessary, until engine accelerates smoothly. High speed stop is factory adjusted. Do not adjust - damage may result. IMPORTANT: Never tamper with the engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact a Sears or other qualified service center, which has proper equipment and experience to make any necessary adjustments. Cable Clamp Screw Speed Control Bracket 00831 Idle Speed Adjusting Screw Idle Fuel Adjusting Needle 28 Throttle Lever STORAGE Immediately prepare your tractor for storage at the end of the season or if the tractor will not be used for 30 days or more. WARNING: Never store the tractor with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. TRACTOR Remove mower from tractor for winter storage. When mower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area. 1. Clean entire tractor (See “CLEANING” in the Maintenance section of this manual). 2. Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). 3. Lubricate as shown in the Maintenance section of this manual. 4. Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. 5. Touch up all rusted or chipped paint surfaces; sand lightly before painting. BATTERY • Fully charge the battery for storage. • After a period of time in storage, battery may require recharging. • To help prevent corrosion and power leakage during long periods of storage, battery cables should be disconnected and battery cleaned thoroughly (see “TO CLEAN BATTERY AND TERMINALS” in the Maintenance section of this manual). • After cleaning, leave cables disconnected and place cables where they cannot come in contact with battery terminals. • If battery is removed from tractor for storage, do not store battery directly on concrete or damp surfaces. ENGINE FUEL SYSTEM IMPORTANT: It is important to prevent gum deposites from forming in essential fuel system parts such as carburetor, fuel hose, or tank during storage. Also, experi- 29 ance indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. • Empty the fuel tank by starting the engine and letting it run until the fuel lines and carburetor are empty. • Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. • Use fresh fuel next season. NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not empty the gas tank and carburetor if using fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See “ENGINE” in the Maintenance section of this manual). CYLINDER(S) 1. Remove spark plug(s). 2. Pour one ounce of oil through spark plug hole(s) into cylinder(s). 3. Turn ignition key to “START” position for a few seconds to distribute oil. 4. Replace with new spark plug(s). OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • If possible, store your tractor indoors and cover it to give protection from dust and dirt. • Cover your tractor with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your tractor to rust. IMPORTANT: Never cover tractor while engine and exhaust areas are still warm.
