Safety Rules
1 - 4
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of rider, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed.
GENERAL OPERATION
• Read, understand, and follow all instructions in the manual and on the unit before starting.
• Only allow responsible adults, who are familiar with the instructions, to operate the unit.
• Clear the area of objects such as rocks, toys, wire, etc., which could be picked up and thrown by the blade(s).
• Be sure the area is clear of other people before mow­ing. Stop unit if anyone enters the area.
• Never carry passengers.
• Do not mow in reverse unless absolutely necessary. Always look down and behind before and while trav­elling in reverse.
• Be aware of the mower discharge direction and do not point it at anyone. Do not operate the mower without either the entire grass catcher or the deflector in place.
• Slow down before turning.
• Never leave a running unit unattended. Always disengage the PTO, set parking brake, stop engine, and remove keys before dismounting.
• Turn off the PTO switch to disengage the blades when not mowing.
• Stop engine before removing grass catcher or unclogging chute.
• Mow only in daylight or good artificial light.
• Do not operate the unit 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 unit into a trailer or truck.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. All slopes require extra caution. If you cannot back up the slope or if you feel uneasy on it, do not mow it.
Do
• Follow manufacturer’s recommendations of wheel weights or counterweights to improve stability.
• Mow up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could overturn the unit. Tall grass can hide obstacles.
• Use slow speed. Choose a low gear so that you will not have to stop or shift while on the slope.
• Use extra care with grass catchers or other attach­ments. These can change the stability of the unit.
• Keep all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction.
Do Not
Do not start or stop on a slope. If tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.
Do not turn on slopes unless necessary, and then, turn slowly and gradually downhill, if possible.
Do not mow near drop-offs, ditches, or embank- ments. The mower could suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.
Do not mow on wet grass. Reduced traction could cause sliding.
Do not try to stabilize the unit by putting your foot on the ground.
Do not use grass catcher on steep slopes.
WARNING - SLOPE OPERATION Never operate on slopes greater than 30 percent (16.7°) which is a rise of three feet vertically in 10 feet horizon­tally. When operating on slopes that are greater than 15 percent (8.5°) but less than 30 percent use front counter­weights and rear wheel weights (see your dealer). Select slow ground speed before driving onto slope. In addition to front and rear weights, use extra caution when operat­ing on slopes with rear-mounted grass catcher. Mow UP and DOWN the slope, never across the face, use caution when changing directions and DO NOT START OR STOP ON SLOPE.

SERVICE AND MAINTENANCE
The service information provided in this manual is intend­ed to provide you with the knowledge required to perform a wide range of service procedures on the listed equip­ment.
While appropriate safety reminders and safety warnings have been included here and elsewhere in this manual to help promote the use of safe service techniques, you must also observe all appropriate shop safety rules whenever performing these procedures.
No single manual, including this one, can include every possible warning or safety instruction necessary to guar­antee complete safety - you must apply your common sense and knowledge of shop and power equipment safety whenever performing service, whenever working around others who are operating, servicing, or handling equipment, and whenever you are present in a work environment where hand or power tools, shop equip­ment, or outdoor power equipment may be present.
This includes taking the necessary safety precautions to help ensure a safe workplace, exercising reasonable care to avoid unsafe acts, and being alert for potential hazards as you move about the workplace or engage in various service activities.
If you encounter a service situation involving the use of an unfamiliar tool, procedure, or part, and rereading the appropriate section of this manual does not provide the information you want, contact your Simplicity dealer before proceeding. Never attempt a repair that you’re not sure about, since help is usually never more than just a phone call away.
Practicing safe service procedures not only helps protect you and those you work around, it also contributes to providing safe, reliable equipment .
Personal Protective Equipment
• Wear protective safety glasses whenever using hand or power tools, shop equipment, and whenever work­ing under power equipment to protect your eyes from falling debris and small parts.
• Wear safety goggles or full face protection when han­dling battery electrolyte fluid, or when performing grinding or sharpening operations that produce sparks or flying debris. Extensive grinding may require the use of protective sleeves and an apron.
• Wear work gloves when handling sharp surfaces such as mower blades, or when working around sharp edges. Never wear gloves that are loose fitting or that have tie straps, as these could cause your hands to get caught by rotating parts, resulting in serious injury. Chemical-resistant Rubber gloves are recommended when handling or pouring battery elec­trolyte.
• Steel-toe safety shoes are highly recommended to protect feet from falling tools, heavy parts, and other shop equipment.
Fuel Handling Safety
• Always use extra care when handling gasoline ­gasoline is highly flammable, and gasoline vapors are explosive as well as toxic if inhaled.
• Never store fuel indoors, or refuel a unit indoors. Gasoline vapors can easily travel unseen to distant sources of ignition such as pilot lights or open flames on water heaters, furnaces, stoves, or other gas operated appliances, sparks from electric motors or other electrically-operated tools and equipment, weld­ing equipment, grinders, or burning smoking materi­als. Contact with these or any other sources of igni­tion will cause an explosion and/or fire, serious per­sonal injury, and damage to property and equipment.
• Never transfer gasoline from one container to another unless the containers are connected by an approved grounding strap. Hand or power operated transfer pumps can generate a static charge of electricity, causing dangerous sparking and ignition of fuel or fuel vapors. Always follow the pump manufacturer’s safety and operating instructions.
• Use only approved containers for fuel, and always handle the container with extreme care to avoid spillage or leaking of explosive vapors.
• Never smoke or allow others in the area to smoke while refilling the fuel tank, or when handling gaso­line cans. Make sure any smoking materials that had been in use in the area are fully extinguished before opening a fuel can or starting refueling .

1 General Information
Safety Rules
Exhaust Gas Safety
• Internal combustion engines produce and exhaust Carbon Monoxide (CO), an odorless, colorless, gas that causes dizziness, nausea, flu-like symptoms, unconsciousness, or even brain damage or death, if breathed for prolonged periods.
• If exposed to Carbon Monoxide gas, get to a fresh air source immediately and seek medical attention. CO can build up in your blood, and can cause lingering symptoms or permanent damage if left untreated.
• Operate the unit outdoors or in a well ventilated area, or pipe exhaust gases out of the work area to an out­side location where the exhaust can be dissipated safely away from doors, windows, air conditioners, or other potential sources of outside-air intake that could permit reentry of hazardous fumes.
• Never enter an enclosed area where an engine has been running and exhaust gases have been allowed to collect. Open adjacent windows or doors first to permit outside air to ventilate the area, and allow suf­ficient time for a complete air exchange to occur.
Battery/Electrolyte Safety
• Lead-Acid batteries use an electrolyte containing sul­phuric acid, a highly corrosive liquid that can cause severe chemical burns if allowed to come into contact with skin, or blindness if allowed to contact your eyes. Always wear approved eye goggles or a full face shield and protective gloves when handling elec­trolyte or filling the battery.
• Lead-acid batteries also produce hydrogen, a color­less, highly explosive gas that can be easily ignited by a single spark. Charging the battery incorrectly or hooking up jumper cables improperly can cause sparking, and must be avoided. Always follow rec­ommended battery charging and jumper cable pro­cedures.
• When removing or installing battery cables, discon­nect the negative cable FIRST, and reconnect it LAST. If not done in this order, the positive terminal could be accidentally shorted to the frame by a tool, creating a dangerous spark that can ignite nearby fuel vapors or escaping hydrogen gas from the battery.
• Keep battery securely fastened in position with vent tube directed down and out of battery compartment. Replace battery if electrolyte leakage occurs. Make sure the battery vent tube is properly installed, and is not plugged with clippings or other debris. Replace the vent tube if cracked, damaged, or missing from unit.
• Old batteries should be disposed of by recycling.
Electrical System Safety
• Loose connectors, worn wires, damaged wire insula­tion, and loose termination hardware can cause sparks, short-circuits, and erratic equipment opera­tion. Always check wiring for damage, and make appropriate repairs before placing unit back into oper­ation.
• Use care when working around exposed terminals to prevent short-circuiting the electrical system. Sparking, electric shocks, and damage to the system may result from accidental contact between terminals and metal hand tools.
Elevation Of Unit Safety
• Always support unit on approved jack stands when working on an elevated unit, and keep unit from rolling by engaging parking brake and placing wheel chocks behind wheels still on floor or work table.
• Secure unit to work-surface of scissor-lift worktables or other powered lift tables in accordance with the manufacturer’s instructions. Unsecured units may roll unexpectedly while work is being done, causing injuries.
• Never work under an elevated unit unless it is proper­ly supported by jack stands, locked from rolling with wheel chocks or equivalent, and you can quickly escape from under the unit in an emergency using a rolling device such as a mechanic’s creeper.
• Always protect your eyes from falling debris or small parts by wearing approved safety glasses or goggles.
• Remove the ignition key and disconnect the spark plug wires before working under a unit. Accidental or inadvertent starting could result in serious injuries.
Proper Tool Use
• Use power and hand tools only for the use that they were designed. Never alter or modify tools, or impro­vise using tools that are not suitable for the job at hand.
• Keep all hand and power tools in good repair, and put them away when done to avoid cluttering the work area. Use extra care when using corded tools around moving or rotating parts such as belts and pulleys, since the cord could get caught and suddenly pull the tool, or you, into the area of moving parts.
• Always check the unit to ensure that all hand and power tools and tool attachments have been removed from the unit after use. Small tools and tool attachments left on the equipment can fall into the cutting path when the unit is placed into service, and become a hazard to bystanders if struck by mower blades.

Safety Rules
1 - 8
Work Area Safety
• Always keep the work area clear of clutter from dis­carded parts, and debris from parts boxes or packag­ing materials. Small parts, hardware items, and other debris or refuse left lying around can become slip, trip, and fall hazards if not removed and discarded of properly.
• Always observe general shop safety rules for house­keeping, and tend to oil spills and other spilled fluids promptly to prevent slip and fall injuries.
• Allow sufficient work area around the equipment you are working on to permit comfortable working posi­tions. Never put yourself in a position that would pre­vent you from escaping quickly in the event of emer­gencies such as sudden shifts in equipment position, fire, or other situations requiring an immediate reac­tion on your part.
Compressed Air Safety
• Always use care when using compressed air to blow dirt and debris off equipment - always direct the air blast away from yourself and others in the area, and protect your eyes with safety glasses to prevent injury from particles that may blow back toward your face.
• Never use high pressure air directly against your skin to clean dirt and debris - the air pressure could actu­ally force foreign material or fluids into your skin, causing serious injuries.
• Use care when filling tires - lawn and garden tractors utilize low pressure tires, and over-pressurization is hazardous to you and anyone who operates the equipment with improper tire pressures. Always con­sult the air pressure recommendations for the unit involved before adding additional air to the tires.
Grease & Lubricant Safety
• Normal service and maintenance involves the use of oils and greases that could present a fire hazard if not handled properly. Always dispose of oily rags properly to prevent fires caused by spontaneous combustion.
• Spilled lubricants pose dangerous slip hazards and must be taken care of immediately. Wipe up spills carefully, or use absorbent materials to soak up spilled fluids. Always dispose of rags, paper towels, and other saturated absorbents properly.
• Store oils and greases away from flame or other igni­tion sources. Petroleum-based fluids can be ignited by smoking materials and sparks - always treat oils and greases as potentially flammable materials. Always cap oil and grease containers when done using, and store or dispose of properly.
General Servicing Safety
• Always check safety devices and switches for proper operation - never alter these devices or make tempo­rary or makeshift repairs. Use only factory-autho­rized parts and procedures, and check newly­installed parts for proper operation.
• Make sure all hardware items are properly tightened, especially blade attachment bolts. Replace any hard­ware that appears damaged.
• Check brake operation, and adjust or repair as required. Always comply with factory specifications on settings and adjustments.
• Check grass catcher components for wear, damage, or deterioration, and replace with factory authorized parts if necessary.
• Always make repairs using factory authorized replacement parts only. Using parts that don’t meet factory specifications can result in sudden or prema­ture failures, poor or erratic equipment performance, and potential safety hazards to operators and bystanders.
• Always comply with factory specifications on settings and adjustments when installing new parts, making repairs, or performing routine service procedures.
• Always test repairs before releasing units to cus­tomers, paying special attention to any items that are safety-related. Correct any problems noted, and re­check to ensure that the problems have been fully remedied.
• Make sure all safety and operating instruction decals are legible, properly located, and securely attached. Replace any decals that can’t be read or are in dan­ger of falling off.
• Always advise equipment owners of any potential operating or safety problems that may be arising due to anticipated wear, and request that the owner address the problem before a hazard develops.
• Never allow a unit to be placed back into service if a serious safety or operating problem is evident. Advise the owner of the problem and the possible hazards associated with the problem, and request permission to correct the deficiencies.
• Use extreme care when working on older models that do not have all of the latest safety devices and switches. Disengage the PTO and transmission before starting the unit, or commencing repairs.
• Always use care when removing or installing parts to prevent damage from dropping or rough handling. Support heavy parts properly to prevent damage or personal injury to yourself and others.

Repair Information
GENERAL REPAIR INFORMATION
In addition to providing specific repair procedures for the equipment listed at the beginning of this section, this manual provides the following additional general instruc­tions for dealing with repairs to various types of compo­nents.
This information is designed to help you deal more effec­tively with these components by providing basic service knowledge and other useful tips.
Bearings & Bushings
Roller bearings, ball bearings, and bushings are used to provide support to rotating shafts and other parts such as gears, pulleys, and sprockets that are used to transmit rotary motion. Over time, bearings and bushings may require additional lubrication to transmit this rotary motion with minimal friction, or may need replacement due to normal operation and wear. Normal service for bearings and bushings includes removal, cleaning, inspection, lubrication, and replacement.
REMOVAL
Most bearings and bushings used on the listed equip­ment can be easily removed by following the appropriate detailed procedures found throughout this manual. Care should always be exercised to avoid scratching or dam­aging the bearing or bushing, the mounting shaft, and surrounding components. Bearing or bushing removal is usually necessary when excessive play or wobble is noticed on the part it supports, when unusual noise or vibration is apparent, or when a burning smell is present at the bearing location.
CLEANING
Sealed bearings and bushings can be cleaned by careful wiping with a cloth. Bearings with one-sided or remov­able shields and plain bushings can be cleaned by immersion in safety solvent, and brushing with a part cleaning brush. Oil-impregnated bushings, and bushings made of nylon or other synthetic materials, can be cleaned with safety solvents, or wiped clean, but should not be immersed in solvent for periods longer than that necessary to remove heavy or caked-on build-ups of grease. All petroleum-based solvents are flammable, so appropriate precautions regarding flames, sparks, and other ignition sources should always be observed. Gasoline should never be used because of its volatility and its highly toxic nature.
INSPECTION
Once cleaned, bearings can be properly inspected for wear, scratches, visible damage such as corrosion, cracked seals or scorching, and rough, or noisy, opera­tion. Bushings can be visually checked for scratches, uneven wear, or other visual damage.
LUBRICATION
After passing inspection, bearings and bushings should be lubricated in accordance with factory specifications, and reinstalled according to the appropriate installation instructions. New bearings and bushings must also be properly lubricated before use. For optimal performance, and as a practical preventive maintenance measure, bearings and bushings used in pairs or multiple sets should all be replaced at the same time.
Belts & Pulleys
Belts and pulleys transmit rotary motion from power sources to work components, providing the force needed to drive transmissions, operate mower decks, and power various attachments. This continual use eventually causes belts to wear out, and over time may also require the replacement of pulleys and pulley bearings.
Belt wear and various types of damage are easily checked by visual examination, which is covered in greater detail elsewhere in this manual. Pulleys may also be checked visually for wear or apparent damage, but pulley bearings usually require removal, cleaning, and inspection to determine if replacement is required.
Belt and pulley life can be optimized by making sure that proper belt tension and alignment are observed when belts are installed. Proper belt tension and alignment should also be maintained by performing periodic checks and adjustments. In addition, only factory authorized replacement belts will minimize problems caused by size, thermal instability, and variations in quality.
Electrical Parts
The electrical parts used on these units has been specif­ically engineered for outdoor power equipment, and is designed to provide years of reliable operation. As with all electrical components and systems, electrical con­tacts must be kept clean and dry, and all terminations must be securely fastened or connected. Also, all elec­trical components, wiring, and connectors should be peri­odically inspected for corrosion, signs of excessive heat build-up, or other damage that signals that it is time to repair or replace the item.
Specific procedures for electrical troubleshooting and most common repairs is covered in separate sections of this manual.

Fasteners & Hardware
All hardware and fasteners used in this equipment must meet factory specifications for SAE grade, size, and torque, and must be kept securely tightened. Locking hardware that degrades with use should be replaced when service is performed in affected areas. Always observe factory specifications for torque, or consult the torque chart for torque information.
Genuine Replacement Parts
Only factory authorized replacement parts should be used when making repairs or performing routine mainte­nance. The use of parts that do not meet stringent facto­ry specifications can cause poor performance, premature failures, and lead to potential safety hazards. In addition, the use of non-factory authorized replacement parts will void your warranty.
Hydraulic Parts
Hydraulic parts are adversely affected by dirt and conta­mination, and care must be exercised when performing service on these parts to prevent foreign material from entering. Specific service information appears else­where in this manual, and all precautions and proce­dures must be followed when repairing or servicing these parts.
Paint
The paint on outdoor power equipment provides for an attractive appearance, as well as a barrier to corrosion caused by exposure to moisture in the environment.
Scratches, abrasions, and other damage to painted sur­faces should be repaired promptly to prevent the forma­tion of rust and premature part failure. Factory supplied paints are available that provide both an accurate color match and superior corrosion resistance.
Required Tools & Equipment
All repairs in this manual can be accomplished with stan­dard mechanic’s hand tools. The use of appropriate power tools such as impact wrenches and power drivers may aid in part removal and replacement, but care must be exercised to avoid causing damage to components from excessive tightening. Transmission service, steer­ing service, tire and wheel service, and service to com­ponents located under the frame also requires the use of a jack with suitable capacity, and jack stands to support the unit being worked on.
Systems Checks
In addition to performing individual component service, components affected by related parts changes should also receive attention at the time service is performed. Examples of this include part replacements that are part of a safety device, electrical components, transmission components, and pulleys that are part of the same power delivery system. Giving attention to related parts will help ensure that the parts most likely to be affected by the wear of similar or nearby parts, or parts subjected to the same amount of stress or wear, are given appropri­ate attention before a failure can occur.

Storage
WARNING
Never store a tractor, with gasoline in engine or fuel tank, in a heated shelter or in an enclosed, poorly ventilated enclosure. Gasoline fumes may reach an open flame, spark or pilot light (such as a furnace, water heater, clothes dryer, etc.) and cause an explosion.
Handle gasoline carefully. It is highly flammable and careless use could result in serious fire damage to your person or property.
Drain fuel into an approved container outdoors away from open flame or sparks.
A. STORAGE
Temporary Storage
(30 Days Or Less)
Remember, the fuel tank will still contain some gasoline, so never store the tractor indoors where fuel vapor could travel to any ignition source. Fuel vapor is also toxic if inhaled, so never store the tractor in any structure used for human or animal habitation.
Here is a checklist of things to do when storing your trac­tor temporarily or in between uses:
• Do not store the tractor in an area where children may come into contact with it. If there is any chance of unauthorized use, remove the ignition key and keep it in a safe place.
• If the tractor cannot be stored on a reasonably level surface, block the wheels.
• Clean all grass and dirt from the mower.
NOTE: If storing your tractor between winter snow
removal jobs in a cold area, we suggest that you fill the fuel tank at the completion of each job to prevent water condensation in the fuel tank. Wait for the engine to cool before filling the tank.
Long Term Storage
(Longer Than 30 Days)
Before you store your tractor for the off-season, read the
Maintenance and Storage instructions in the Safety Rules section, then perform the following steps:
1. Drain crankcase oil and refill with a grade of oil that will be required when tractor is used again.
2. Prepare the mower deck for storage as follows:
a. Remove mower deck from the tractor. (See
Operators Manual)
b. Clean underside of mower deck.
c. Coat all bare metal surface with paint or light coat
of oil to prevent rusting.
3. Clean external surfaces and engine.
4. Prepare engine for storage. See engine owner’s manual.
5. Clean any dirt or grass from cylinder head cooling fins, engine housing and air cleaner element.
6. Cover air cleaner and exhaust outlet tightly with plas­tic or other waterproof material to keep out moisture, dirt and insects.
7. Completely grease and oil tractor as outlined in the Lubrication section.
8. Clean up tractor and apply paint or rust preventative to any areas where paint is chipped or damaged.
9. Be sure the battery is filled to the proper level with water and is fully charged. Battery life will be increased if it is removed, put in a cool, dry place and fully charged about once a month. Do not allow the battery to freeze. If the battery is left in the tractor, disconnect the negative cable.
10. Drain the fuel system completely or add a gasoline stabilizer to the fuel system. If you have chosen to use a fuel stabilizer and have not drained the fuel system, follow all safety instructions and storage pre­cautions in this manual to prevent the possibility of fire from the ignition of gasoline fumes. Remember, gasoline fumes can travel to distant sources of igni­tion and ignite, causing risk of explosion and fire.
NOTE: Gasoline, if permitted to stand unused for extend­ed periods (30 days or more), may develop gummy deposits which can adversely affect the engine carbure­tor and cause engine malfunction. To avoid this condi­tion, add a gasoline stabilizer to the fuel tank or drain all fuel from the system before placing unit in storage.
11. Transport the tractor to a suitable, dry, indoor loca­tion. If the tractor is to be stored 6 months or longer, block the tractor up off the wheels to relieve weight and also to keep the tires off a damp floor. Protect tires from prolonged exposure to direct sunlight.

Storage
Starting After Long Term Storage
Before starting the tractor after it has been stored for a long period of time, perform the following steps:
1. Remove the blocks from under the tractor.
2. Install the battery if it was removed.
3. Unplug the exhaust outlet and air cleaner.
4. Fill the fuel tank with fresh gasoline. See engine manual for recommendations.
5. Check crankcase oil level and add proper oil if necessary.
6. Inflate tires to proper pressure.
7. Check all fluid levels.
8. Start the engine and let it run slowly until warm. DO NOT run at high speed immediately after starting. Be sure to run engine only outdoors or in well ventilated areas.
B. PREVENTIVE MAINTENANCE CHART
The following schedule should be followed for normal care of your tractor and mower. You will need to keep a record of your operating time. Determining operating time is easily accomplished by multiplying the time it takes to do one job by the number of times you’ve done the job, or you can install the optional hour meter.
Safety Items Before Before Every Every Every 100 Spring
First Use Each Use 5 Hours 25 Hours Hours & Fall
Check safety interlock system. •• Check tractor brakes. •• Check mower blade stopping time. After adjustment or service of electric PTO clutch
Normal Care Items

Engine
C. MAINTENANCE & ADJUSTMENTS
ENGINE OIL LEVEL
Engine oil level must be checked at regular intervals to ensure that engine oil is maintained at a level that will provide for adequate lubrication of internal components. Operating the engine with insufficient oil in the oil sump will cause engine components to wear prematurely, and prolonged use with low oil levels may cause engine over­heating, permanent damage, and voiding of the engine manufacturer’s warranty.
In addition to following the engine manufacturer’s instruc­tions for checking oil level, the recommendations for oil type and viscosity must also be followed. These recom­mendations vary based on the season during which the unit is being operated, and may require that the oil be changed to suit different operating conditions.
The location of the oil level indicator and oil fill tube are indicated in the engine manufacturer’s manual shipped with each unit. In general, the oil fill tube is marked with an oil can symbol or the word “OIL”, and is located next to the engine to permit easy access (See Figures 1 through 3).
The engine oil fill tube is usually also the location of the engine oil level dipstick, allowing oil level checks and fill­ing to be performed using the same tube.
ENGINE OIL FILTER
The engine oil filter should be changed in accordance with the engine manufacturer’s recommendations, which is generally every 50 hours of operation, or more fre­quently when operating conditions are hot (over 85°), or dusty.
The oil filter removes abrasive particles and other conta­minants from the oil, keeping it clean for maximum lubri­cation efficiency, and should only be replaced with the type of filter recommended by the engine manufacturer.
The oil filter is located at the base of the engine, and is removed by unscrewing the filter from the filter base using an oil filter wrench (See Figures 1 through 3).
ENGINE AIR FILTER
The engine air filter filters out dust and dirt from the air intake of the engine, and must be cleaned or replaced every 25 hours of operation, or more frequently when operating conditions are dusty.
Follow the engine manufacturer’s recommendations for removal, cleaning, and replacement. See Figures 1 through 3 for air filter locations.

FUEL FILTER
The fuel filter is located in the engine compartment and is installed in the rubber fuel line between the fuel tank and the fuel pump (See Figures 1 through 4). The fuel filter should be checked every 100 hours of operation, or sooner and replaced if it appears to be dirty or clogged.
A dirty or clogged filter may cause erratic engine opera­tion, hard starting, or loss of power.
Before removing the hoses from the fuel filter, place a small container under the filter to catch the gasoline in the hoses and filter that will drain out as the filter is removed.
1. Squeeze the tabs on the hose clamps together using a pliers, and slide the clamps away from the fuel fil­ter.
2. Note the fuel flow direction indicated on the filter, and remove the filter by pulling the hoses away from the filter with a twisting motion. Be prepared for fuel in the hoses and fuel filter to drain out as the hoses are disconnected, and catch the fuel in the container.
3. Observing the same fuel filter flow direction noted during removal, install the new fuel filter in the fuel line by sliding the hoses onto the filter.
4. Squeeze the tabs on the hose clamps together, and slide the clamps into place over the fuel filter tubes to secure the fuel lines to the fuel filter.
NOTE: The hose clamps must connect the fuel line hoses to the fuel filter securely to prevent fuel leakage and the possibility of engine compartment fire. Replace the hose clamps if they do not provide a secure, leak­proof attachment to the fuel filter.
NOTE: Replace old, brittle, hard, or cracked fuel line.

DANGER
Do not remove fuel filter when engine is hot, as spilled gasoline may ignite. Follow all precau­tions for the safe handling of gasoline when removing and installing the fuel filter. DO NOT spread hose clamps more than necessary. Replace clamps if they do not provide a secure, leak-proof attachment to the fuel filter when rein­stalled.

WARNING
Be careful when handling the battery. Avoid spilling electrolyte. Keep flames and sparks away from the battery.
WARNING
When removing or installing battery cables, dis­connect the negative cable FIRST and reconnect it LAST. If not done in this order, the positive ter­minal can be shorted to the frame by a tool.
SPARK PLUG
The spark plug(s) should be inspected at the regular intervals specified in the engine manufacturer’s owner’s manual and cleaned or replaced as required.
Dirty, worn, or fouled spark plugs may cause hard start­ing, rough engine operation, or loss of power, and may contribute to premature starter failure from excessive cranking of the engine.
The spark plug(s) can be found by looking for the thick black spark plug cable(s) at the engine head, and remov­ing the spark plug boot(s) that connect(s) the cable to the spark plug.
The spark plug boot can be removed from the spark plug by pulling the boot away from the spark plug with a slight side-to-side motion.
To remove the spark plug(s) from the engine for inspec­tion or replacement:
1. Turn the ignition off and remove the key.
2. Raise the hood.
3. Locate the spark plug cable and boot, and pull the boot off the spark plug (Figure 5).
4. Using a spark plug socket and socket wrench or equivalent spark plug removal tool, unscrew the spark plug from the engine by turning the spark plug counter-clockwise.
5. Inspect the spark plug in accordance with the engine manufacturer’s instructions, and clean, re-gap, or replace the spark plug as required.
6. When reinstalling the spark plug, start the plug into the engine by first turning it clockwise by hand to pre­vent cross-threading and possible damage to the spark plug port. Tighten as instructed in engine man­ufacturer’s manual.

Lubrication
LUBRICATION
Lubricating the Tractor
Lubricate the tractor as shown in Figures 10 through
17. When a grease gun is shown, wipe the fitting clean, apply two or three pumps of lithium base automotive grease, and wipe off excess grease. When an oil can is shown, wipe the area clean, apply a few drops of SAE 30 weight oil, then wipe up drips or spills.
In general, linkage connections and other parts that have partial rotational or sliding movement (pedal pivot points, steering links, etc.) should be lubricated periodically with SAE 30 weight oil. Avoid applying excessive amounts of oil since this may cause a build-up of dirt and grass clip­pings around the lubricated area, making subsequent lubrication more difficult to accomplish.
Roller bearings, bushings, axles, rotating assemblies with grease fittings, and mechanisms with exposed gear teeth (steering gears) require periodic lubrication with lithium grease.
When grease fittings are present, a manual or pneumatic pressure-feed grease gun should be utilized to inject enough grease through the fitting to fully permeate the enclosed area containing the bearings or other moving parts.
Plain bushings, bearings, axles without grease fittings, and exposed gear teeth require the direct application of grease to all wear surfaces. Use a small, clean applicator brush or other means of applying and spreading the grease evenly.
Special care should be taken with ball and roller bearings to ensure that a liberal application of grease is applied to the bearing rollers or balls, and both inner and outer races or bearing and bearing cups.

Rear 6-8 psi (41-55 kPa)
TIRE PRESSURE
Front and rear tires should be checked periodically to ensure that proper tire pressure is maintained. Note that these pressures differ slightly from the “Max Inflation” stamped on the side-wall of the tire. Keeping the tires properly inflated to these settings helps provide proper traction, extend tire life, and improved cut quality.

LUBRICATING THE MOWER
Lubricate the mower as shown in Figures 20 through 22. Be sure to include the grease fittings on the mower idler pulley and arbors, which are located underneath the mower deck. Always wipe the grease fittings clean before adding grease to help prevent forcing dirt and other wear-causing contaminants into the lubrication area.
When oil is indicated, use SAE 30 weight oil. Brush any dirt and grass from the area to be lubricated, and wipe lubrication points clean before applying oil. This will ensure that oil can get into the area where it is required.
Avoid getting grease or oil on belts and pulley when applying lubricants, and always wipe away excess oil and grease to prevent a rapid build-up of dirt and debris from accumulating.
