TO ADJUST MOWER CUTTING HEIGHT The cutting height is controlled by tuming the height adjustment knob in desired direction. •Tum knob clockwise (C,) to raise cutting height. , • /urn KnOD counterclockwise (O) to lower cutting height. 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 approximateandmayvary depending upon soilconditions,heightof grassand typesof grassbeingmowed. • 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. TO ADJUST GAUGE WHEELS Gauge wheels are propedy 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. • Adjust gauge wheels with tractor on a flat level surface. • Adjust mower to desired cutting height (See "TO ADJUST MOWER CUTTING HEIGHT" in the Operation section of this manual). • With mower in desired height of cut position, gauge wheels should be assembled so they are slightly off the ground. Install gauge wheel in appropriate hole with shoulder bolt, 3/8 washer, and 3/816 Iocknut and tighten securely. • Repeat for opposite side installing gauge wheel in same adjustment hole. •,CAUTION: Do not operate the mower without either the entire grasscatcher, on mowers so equipped, or the dtscharge guard in place.

RNING: Experience 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. 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 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 ATrACHMENTS empty. Use fresh fuel next season. See Storage Instructions for additional information. Never use engine or carburetor cleaner products in the fuel t_k or permanent damage may occur. CAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame. TO START ENGINE Tow only the attachments that are recommendedby 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. Sres can lose traction with the ground and cause you to lose control of your tractor. BEFORE CHECK STARTING 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. • Be sure freewheel control is in the THE ENGINE transmission engaged position. • Sit on seat in operating position, depress clutch/brake pedal and set parking brake. • Place motion control lever in neutral (N) _ position. • Move attachment clutch to =DISEN- OIL LEVEL • The engine in your tractor has been shipped, from the factory, already filled with summer weight oil. • Check engine oil with tractor on level ground. • Unthread and remove oil fill cap/dip stick; wipe oil off.

Do not run starter continuouslyfor 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. ADD GASOLINE • Fill fuel tank. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. (Use of leaded gasoline _11 increase carbon and lead oxide deposits and reduce valve life). Do not mix oil with gasoline. Purchase fuel in qo_afitities that can be used within 30 days to assure fuel freshness. 16 WARM WEATHER AND ABOVE) STARTING (50 ° F • 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. • 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 BELOW) STARTING (50 ° FAND • 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. AUTOMATIC TRANSMISSION WARM-UP • Before driving the unit in cold weather, the transmission should be warmed up as follows: • Be sure the tractor is on level ground. • Place the motion control lever in neutral. Release the parking brake and let the clutch/brake slowly return to operating position. • 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: 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. PURGE TRANSMISSION ,_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 removeal for service or replacement, it should be purged after reinstallation before operating the tractor. • Place tractor safely on level surface with engine off and parking] brake set. • Disengage transmission by placing freewheel control in freewheeling position (See =TO TRANSPORT" in this section of manual). • Sitting in the tractor seat, start engine.

Repeat this procedure three (3) times. NOTE: During this procedure there will be no movement of drive wheels. The air is being removed from hydraulic drive system. • Move motion control lever to neutral (N) position. Shut off engine and set parking brake. • Engage transmission by placing freewheel control in driving position (See =TO TRANSPORT" in this section of manual). • Sitting in the tractor seat, start engine. After the engine is running, move throttle control to haft (1/2) speed.

Repeat this procedure with the motion control lever three (3) times. • Your tractor is now purged and now ready for normal operation. 17 MOWING TIPS •"l]ra MULCHING chains cannot be used when the TIPS IMPORTANT: For best performance, keep mower housing free of built-up grass and trash. Clean after each use. • The special mulching blade will recut the grass clippings many times and reduce them in size so that as they fall onto the lawn they will disperse into the grass and not be noticed. Also, the mulched grass will biodegrade quickly to provide nutrients for the lawn. Always mulch with your highest engine (blade) speed as this will provide the best recutting action of the blades. • Avoid cutting your lawn when it is wet. Wet grass tends to form clumps and interferes with the mulching action. The best time to mow your lawn is the early aftemoon. At this time the grass has dried and the newly cut area will not be exposed to the direct sun. • For best results, adjust the mower cutting height so that the mower cuts off only the top one-third of the grass blades. For extremely heavy mulching, reduce your width of cut on each pass and mow slowly. • Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut, mow across or perpendicular to the first cut path. • Change your cutting pattern from week to week. Mow north to south one week 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 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 tuming 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 the best 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 attachn_nt being used. ( MOWING then change to east to west the next week. This will help prevent matting and graining of the lawn. i=,.. 18 CUSTOMER RESPONSIBILITIES .A, .ANC SC.EOULE .EGua.

If adjustment is necessary, proceed as follows: • With engine not running, move choke control (located on dash panel) to full choke position. • Remove air cleaner cover, filter and cartridge plate to expose carburetor choke (See =AIR FILTER" in the Customer Responsibilities section of this manual). • Choke should be closed. If it is not, loosen casing clamp screw and move choke cable until choke is completely closed. Tighten casing clamp screw securely. • Reassemble air cleaner. TO ADJUST CARBURETOR The carburetor has been present 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 the seats in carburetor may result if screw is turned in too tight. PRELIMINARY SETTING - • Be sure you have a clean air filter, and the throttle control cable is adjusted propedy (see "TO ADJUST THROTTLE CONTROL CABLE" in the Service and Adjustments section of this manual). • With engine off turn idle fuel adjusting needle in (clockwise) closing it finger tight and then turn out (counterclockwise) 1 turn. FINAL SETTING - • Start engine and allow to warm for five minutes. Make final adjustments with engine running and shift]motion control lever in neutral (N) position. • The high idle is set at the factory and cannot be adjusted. • Idle speed settina - With throttle control lever in slow position, engine should idle at 1200 RPM. If engine idles too slow or fast, turn idle speed adjusting screw in or out until correct idle is attained. • Idle fuel needle settina - With throttle control lever in slow position, turn idle fuel adjusting needle in (clockwise) until engine speed decreases and then turn out (counterclockwise) approximately 3/4 turn to obtain the best low speed performance. • Recheck idle speed. Readjust sary. ACCELERATION if neces- TEST - • Move throttle control lever from slow to fast position. If engine hesitates or dies, turn idle fuel adjusting needle out (countemlockwise) 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 facory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact your nearest authorized service center/department, which has proper equipment and experience to make any necessary adjustments.

Remove all dirt, grease, leaves, etc. Store in a clean, dry area. • Clean entire tractor (See =CLEANING" in the Maintenance section of this manual). • Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). • Lubricate as shown in the Maintenance section of this manual. • Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. • Touch up all rusted or chipped paint surfaces; sand lightly before painting. BATTERY Also, experience 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. • Drain the fuel tank. • Start the engine and let 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 drain 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). CYLINDERS • 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 • Remove spark plug(s). • Pour one ounce of oil through spark plug hole(s) into cylinder(s). • Turn ignition key to =START" position for a few seconds to distribute oil .... • Replace with new spark plug(s). OTHER • Do not store gasoline from one season to another. this ma,aual). • 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. • Replace your gasoline can if it 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. ENGINE FUEL SYSTEM Do not use plastic. Plastic cannot breathe, which allows condensation to form and cause your tractor to rust. IMPORTANT: Never cover tractor while engine and exhaust areas are still warm. IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel filter, _uel_hose, or tank during storage. 31 TROUBLESHOOTING PROBLEM Will not start CHART CAUSE CORRECTION • Out of fuel. • Engine not "CHOKED" properly. • Engine tiooded. • • • • Bad spark plug.
