FAILURE TO OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH. • WARNING: In order to prevent accidental starting when setting up, transporting, adjusting or making repairs, always disconnect spark plug wire and place wire where it cannot contact spark plug. • • • WARNING: Do not coast down a hill in neutral, you may lose control of the tractor. • • WARNING: Tow only the attachments that are recommended by and comply with speciﬁcations of the manufacturer of your tractor. Use common sense when towing. Operate only at the lowest possible speed when on a slope. 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. • • • • WARNING • Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. • WARNING II. SLOPE OPERATION Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling. I. GENERAL OPERATION • • • • • • • • Read, understand, and follow all instructions on the machine and in the manual before starting. 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. 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. 2 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. SAFETY RULES Safe Operation Practices for Ride-On Mowers III. CHILDREN 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. Check their proper operation regularly. • Keep machine free of grass, leaves, or other debris build-up. Clean oil or fuel spillage and remove any fuelsoaked 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. 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. • 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. • 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. • • • • • • • • • 3 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. 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.

(l) ATTACHMENT CLUTCH SWITCH PULL OUT TO “ENGAGE” TO USE THROTTLE CONTROL - D (See Fig. 6) Always operate engine at full speed (fast). • Operating engine at less than full speed (fast) reduces engines operating efﬁciency. • Full speed (fast) offers the best bagging and mower performance. TO MOVE FORWARD AND BACKWARD (See Fig. 7) o ( ) PUSH-IN TO “DISENGAGED” The direction and speed of movement is controlled by the forward and reverse drive pedals. • Start tractor and release parking brake. • Slowly depress forward (K) or reverse (L) drive pedal to begin movement. Ground speed increases the further down the pedal is depressed. FIG. 5 GROUND DRIVE • To stop ground drive, depress brake pedal all the way down. TO USE CRUISE CONTROL -J (See Fig. 7) ENGINE • Move throttle control (D) between half and full speed (fast) position. NOTE: Failure to move throttle control between half and full speed (fast) position, before stopping, may cause engine to “backﬁre”. • Turn ignition key (F) to “STOP” position and remove key. Always remove key when leaving tractor to prevent unauthorized use. • Never use choke (N) to stop engine. The cruise control feature can be used for forward travel only. 9 OPERATION NOTE: Adjust gauge wheels with tractor on a ﬂat level surface. • Adjust mower to desired cutting height (See “TO ADJUST MOWER CUTTING HEIGHT” in this section of 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. Tighten securely. • Repeat for all, installing gauge wheel in same adjustment hole. J K L FIG. 7 SYSTEM CHARACTERISTICS The cruise control should only be used while mowing or transporting on relatively smooth, straight surfaces. Other conditions such as trimming at slow speeds may cause the cruise control to disengage. Do not use the cruise control on slopes, rough terrian or while trimmimg or turning. • With forward drive pedal depressed to desired speed, pull cruise control lever (J) up and hold while lifting your foot off the pedal, then release the lever. To disengage the cruise control, depress the brake pedal or tap on forward drive pedal. FIG.9 TO ADJUST MOWER CUTTING HEIGHT (See Fig. 8) 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 with attachment lift lever. 2. Start mower blades by engaging attachment clutch control. The position of the attachment lift lever (A) determines the cutting height. A TO STOP MOWER BLADES disengage attachment clutch control. CAUTION: Do not operate the mower without either the entire grass catcher, on mowers so equipped, or the deﬂector shield (S) in place. FIG. 8 • Put attachment lift lever in desired cutting height slot. The cutting height range is approximately 1" to 4". 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. S FIG. 10 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. TO ADJUST GAUGE WHEELS (See Fig. 9) 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. 10 OPERATION 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. Transmission Engaged USING THE REVERSE OPERATION SYSTEM Only use if you are certain no children or other bystanders will enter the mowing area. • Depress brake pedal all the way down. • With engine running, turn ignition key counterclockwise to ROS "ON" position. • Look down and behind before and while backing. • Slowly depress reverse drive pedal to start movement. • When use of the ROS is no longer needed, turn the ignition key clockwise to engine "ON" position. ROS "ON" POSITION Transmission Disengaged FIG. 11 SERVICE REMINDER/HOUR METER Service reminder shows the total number of hours the engine has run and ﬂashes to indicate that the engine or mower needs servicing. When service is required, the service reminder will ﬂash for two hours. To service engine and mower, see the Maintenance section of this manual. NOTE: Service reminder runs when the ignition key is in any position but "STOP". For accurate reading, be sure key remains in the "STOP" position when engine is not running. ENGINE "ON" POSITION (NORMAL OPERATING) 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. 02828 TO OPERATE ON HILLS CAUTION: Do not drive up or down hills with slopes greater than 15° and do not drive across any slope. • • • • • • 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. • Check engine oil with tractor on level ground. • Remove oil ﬁll cap/dipstick and wipe clean, reinsert the dipstick and screw cap tight, wait for a few seconds, 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 “OIL VISCOSITY CHART” in the Maintenance section of this manual). • To change engine oil, see the Maintenance section in 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. To restart movement, slowly release parking brake and brake pedal. Slowly depress appropriate drive pedal to slowest setting. Make all turns slowly. TO TRANSPORT (See Figs. 3 and 11) When pushing or towing your tractor, be sure to disengage transmission by placing freewheel control in freewheeling position. Free wheel control is located at the rear drawbar of tractor. • Raise attachment lift to highest position with attachment lift control. • Pull freewheel control out and down 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 reengage transmission, reverse above procedure. 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.). 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. 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 GAS O LINE TO HELP INSURE GOOD COLD WEATHER STARTING. 11 OPERATION 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: 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. 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. TO START ENGINE (See Fig. 3) 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 transmission engaged position. • Sit on seat in operating position, depress brake pedal and set parking brake. • Move attachment clutch to “DISENGAGED” position. • Move throttle control to choke position. NOTE: Before starting, read the warm and cold starting procedures below. • 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, move throttle control to fast position, wait a few minutes and try again. If engine still does not start, move the throttle control back to the choke position and retry. IMPORTANT: SHOULD YOUR TRANSMISSION REQUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR. • • • Place tractor safely on a level surface - that is clear and open - 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. After the engine is running, move throttle control to slow position. Disengage parking brake CAUTION: At any time, during step 4, there may be movement of the drive wheels. WARM WEATHER STARTING (50° F and above) • When engine starts, move the throttle control to the fast position. • 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) • When engine starts, allow engine to run with the throttle control in the choke position until the engine runs roughly, then move throttle control to fast position. This may require an engine warm-up period from several seconds to several minutes, depending on the temperature. • Depress forward drive pedal to full forward position, hold for ﬁve (5) seconds and release pedal. Depress reverse drive pedal to full reverse position, hold for ﬁve (5) seconds and release pedal. Repeat this procedure three (3) times. • Shut- off engine and set parking brake. • Engage transmission by placing freewheel control in engaged 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 half (1/2) speed. Disengage parking brake. • Drive tractor forward for approximately ﬁve feet then backwards for ﬁve feet. Repeat this driving procedure three times. Your transmission is now purged and now ready for normal operation. 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. • Release the parking brake and let the 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 also be used during the engine warm-up period after the transmission has been warmed up. 12 OPERATION MOWING TIPS • • • • 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 machine. 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 (See Fig. 12). FIG. 12 • • • • 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.
