DANGER: THIS CUTTING MACHINE IS CAPABLE OF AMPUTATING HANDS AND FEET AND THROW ING OBJECTS. FAILURE TO
OBSERVE THE FOLLOWING SAFETY INSTRUCTIONS COULD RESULT IN SERIOUS INJURY OR DEATH.
Do not operate machine without the entire grass catcher,
WARNING: In order to prevent ac ci ­den tal starting when setting up, trans­ port ing, ad just ing or making repairs, al ways dis con nect spark plug wire and place wire where it can not 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 rec om mend ed by and comply with spec i fi ca tions of the man u fac tur er of your tractor. Use common sense when towing. Operate only at the low­ est possible speed when on a slope. Too heavy of a load, while on a slope, is dan ger ous. Tires can lose trac tion with the ground and cause you to lose control of your tractor.
WARNING
Engine exhaust, some of its con stit u ents, and cer­ tain vehicle com po nents contain or emit chem i cals known to the State of Cal i for nia to cause can cer and birth de fects or oth er re pro duc tive harm.
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 road­ ways.
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 them selves 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.
WARNING
Battery posts, terminals and related ac ces so ries contain lead and lead compounds, chem i cals known to the State of Cal i for nia to cause can cer and birth defects or oth er re pro duc tive 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 in struc tions, 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 back­ ing.
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.
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 at tach ments; 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
Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the ma chine 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.
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 run ning.
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.
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. Al ways 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.

OPERATION
The cutting height range is ap prox i mate ly 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 de sired height.
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.
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.
USING THE REVERSE OPERATION SYSTEM ­Only use if you are certain no children or other bystanders
will enter the mowing area.
Move motion control lever to neutral (N) position.
With engine running, turn ignition key counterclockwise
to ROS "ON" position.
Look down and behind before and while backing.
Slowly move motion control lever to reverse (R) po si tion
to start movement.
When use of the ROS is no longer needed, turn the
ignition key clockwise to engine "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 AT TACH ­MENTS
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.
BEFORE STARTING THE ENGINE
CHECK ENGINE OIL LEVEL
The engine in your tractor has been shipped, from the factory, already filled with sum mer 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 sec tion of this manual).
To change engine oil, see the Maintenance section in this manual.
ADD GASOLINE
Fill fuel tank to bottom of filler neck. Do not overfill. Use fresh, clean, regular un lead ed 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 quan ti ties 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 START ING.
CAUTION: Alcohol blended fuels (called gas o hol or using ethanol or methanol) can at­tract moisture which leads to sep a ra tion and for ma tion 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 stor age 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 sea son. See Storage In struc tions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
TO START ENGINE (See Fig. 5)
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 en gaged 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 “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 sec onds 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.
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.

• 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 tem per a ture.
AUTOMATIC TRANSMISSION WARM UP
Before driving the unit in cold weather, the trans mis sion should be warmed up as follows:
• Be sure the tractor is on level ground.
• Place the motion control lever in neutral. Re lease 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 also be used during the engine warm-up period after the transmission has been warmed up.
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.
PURGE TRANSMISSION
CAUTION: Never engage or disengage freewheel lever while the engine is
run ning.
5. Shut- off engine and set parking brake.
6. Engage transmission by placing freewheel control in engaged position (See “TO TRANSPORT” in this sec­ tion 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. 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 op er a tion.
MOWING TIPS
Mower should be properly leveled for best mowing per­ for mance. See "TO LEVEL MOWER HOUSING" in the Service and Adjustments section of this manual.
The left hand side of mower should be used for trim­ ming.
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, drive ways, etc. After one or two rounds, mow in the opposite direction making left hand turns until finished (See Fig. 10).
To ensure proper operation and performance, it is rec om ­mend ed 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 de­ vel oped during shipping of your tractor.
IMPORTANT: SHOULD YOUR TRANSMISSION RE QUIRE REMOVAL FOR SERVICE OR REPLACEMENT, IT SHOULD BE PURGED AFTER REINSTALLATION BEFORE OPERATING THE TRACTOR.
1. Place tractor safely on a level surface - that is clear and open - with engine off and parking brake set.
2. Disengage transmission by placing freewheel control in freewheeling 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. Dis­ en gage parking brake
CAUTION: There may be movement of the drive wheels at any time.
4. 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.
FIG. 10
If grass is extremely tall, it should be mowed twice to reduce load and possible fire hazard from dried clip­ pings. 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 mow- ing to assure better mowing performance and proper dis charge of ma te ri al. Regulate ground speed by se­ lect ing a low enough gear to give the mower cutting per for mance 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.

MAINTENANCE
TRACTOR
Always observe safety rules when per form ing any main­ te nance.
BRAKE OPERATION
If tractor requires more than five (5) feet to stop at highest speed in high est gear on a level, dry concrete or paved surface, then brake must be checked and ad just ed. (See “TO ADJUST BRAKE” in the Ser vice and Ad just ments section of this manual).
TIRES
Maintain proper air pressure in all tires (See “PROD UCT SPEC I FI CA TIONS” section of this man ual).
Keep tires free of gasoline, oil, or insect control chemi­ cals 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 pre vent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer. Tire sealant also pre vents tire dry rot and corrosion.
OPERATOR PRESENCE SYS TEM AND REVERSE OP­ERATION SYSTEM (ROS)
Be sure operator presence and reverse operation sys tems are work ing properly. If your tractor does not function as described, repair the problem immediately.
The engine should not start unless the brake pedal is fully de pressed, and the attachment clutch con trol is in the dis en gaged position.
CHECK OPERATOR PRESENCE SYSTEM
When the engine is running, any attempt by the op er a tor to leave the seat without first setting the parking brake should shut off the engine.
When the engine is running and the at tach ment 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.
CHECK REVERSE OPERATION (ROS) SYSTEM
When the engine is running with the ignition switch in the engine "ON" position and the at tach ment clutch engaged, any attempt by the operator to shift into reverse should shut off the engine.
When the engine is running with the ignition switch in the ROS "ON" position and the at tach ment clutch en­gaged, any attempt by the operator to shift into reverse should NOT shut off the engine.

TO SHARPEN BLADE (See Fig. 12)
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 un-
bal anced blade will cause excessive vibration and even tual dam age 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.
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 bal anc er.)
NOTE: Do not use a nail for balancing blade. The lobes of the center hole may appear to be centered, but are not.
16
MAINTENANCE
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.

BATTERY
Your tractor has a battery charging system which is suf fi cient 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 nec es sary.
TO CLEAN BATTERY AND TERMINALS Corrosion and dirt on the battery and terminals can cause
the battery to “leak” power.
Disconnect BLACK battery cable first then RED bat­ tery cable and remove battery from tractor.
Rinse the battery with plain water and dry.
Clean terminals and battery cable ends with wire brush until bright.
Coat terminals with grease or petroleum jelly.
Reinstall battery (See “REPLACING BATTERY” in the Service and Adjustment sec tion of this manual).
V-BELTS
Check V-belts for deterioration and wear after 100 hours and replace if necessary. The belts are not adjustable. Re place belts if they begin to slip from wear.
TRANSAXLE COOLING
Keep transaxle free from build-up of dirt and chaff which can restrict cooling.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, they will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.
Change the oil after every 50 hours of operation or at least once a year if the tractor is not used for 50 hours in one year.
Check the crankcase oil level before starting the engine and after each eight (8) hours of operation. Tighten oil fill cap/dipstick securely each time you check the oil level.
TO CHANGE ENGINE OIL (See Figs. 13 and 14) Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
Be sure tractor is on level surface.
Oil will drain more freely when warm.
Catch oil in a suitable container.
Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine when changing oil.
Remove yellow cap from end of drain valve and install the drain tube onto the fitting.

MAINTENANCE
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent engine dam age from overheating. Clean with a wire brush or com pressed air to re move dirt and stubborn dried gum fibers.
AIR FILTER
Your engine will not run properly using a dirty air filter. Service air cleaner more often under dusty conditions. See Engine Manual.
ENGINE OIL FILTER
Replace the engine oil filter every season or every other oil change if the tractor is used more than 100 hours in one year.
MUFFLER
Inspect and replace corroded muffler and spark arrester (if equipped) as it could create a fire hazard and/or dam­age.
SPARK PLUGS
Replace spark plugs at the beginning of each mowing sea­son or after every 100 hours of use, whichever comes first. Spark plug type and gap setting is shown in "PROD UCT SPECIFICATIONS" section of this manual.
IN-LINE FUEL FILTER (See Fig. 15)
The fuel filter should be replaced once each season. If fuel filter becomes clogged, ob struct ing fuel flow to car bu re tor, re place ment is re quired.
With engine cool, remove filter and plug fuel line sec­ tions.
Place new fuel filter in position in fuel line with arrow pointing towards carburetor.
