1 General Information
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.
Elevating Unit Safely
• 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.

1 General Information
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.
1 General Information
Repair Information
1 - 10
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.
STORAGE
Temporary Storage
(30 Days Or Less)
Remember, the fuel tank will still contain some gasoline,
so never store the tractor indoors or in any other area
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:
• Keep the tractor in an area away from where children may come into contact with it. If there’s any
chance of unauthorized use, remove the spark
plug(s) and put in a safe place. Be sure the spark
plug opening is protected from foreign objects with
a suitable cover.
• If the tractor can’t be stored on a reasonably level
surface, chock 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 engine to cool
before filling 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 while engine is hot 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.
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
Normal Care 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. If battery is left in
tractor, disconnect the negative cable.
10. Drain 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.

3 Maintenance
Storage / Chart
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. Check fluid levels.
7. 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.
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.

ENGINE MAINTENANCE
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 and
2).
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 and 2).
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 2-1
through 2-3 for air filter locations.

Fuel Filter Service
The fuel filter is located in the engine compartment and
is installed in the rubber fuel line between the fuel tank
and the carburetor (See Figure 3). The fuel filter should
be checked every 100 hours of operation, or sooner if
the filter appears dirty or becomes 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.

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 Service
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. Raise the hood.
2. Locate the spark plug cable and boot, and pull the
boot off the spark plug (Figure 4).
3. 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.
4. Inspect the spark plug in accordance with the engine
manufacturer’s instructions, and clean, re-gap, or
replace the spark plug as required.
5. 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.

Mower Blade Service
MOWER BLADE SERVICE
1. Remove mower from the tractor.
2. Blades should be sharp and free of nicks and dents.
If not, sharpen blades as described in following steps.
3. To remove blade for sharpening, use wooden block
to hold blade while removing the blade mounting capscrew (Figure 6).
4. Use a file to sharpen blade to fine edge. Remove all
nicks and dents in blade edge. If blade is severely
damaged, it should be replaced.
5. Balance the blade as shown in Figure 7. Center the
blades’ hole on a nail lubricated with a drop of oil. A
balanced blade will remain level.
6. Reinstall each blade with the tabs pointing up toward
deck as shown in Figures 8 and 9. Secure with a capscrew (D), cup washer (C) and spline (or hex) washer
(B). Use a wooden block to prevent blade rotation
and torque capscrews to 50-70 ft.lbs. (67-95 N.m.).

Lubrication
LUBRICATION
Lubricating the Tractor
Lubricate the tractor as shown in Figures 10 through
16. When a grease gun is shown, wipe the fitting clean,
apply two or three shots 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.

Lubrication

Figure 17. Arbor Lubrication Points
Lubricating the Mower
Lubricate the mower as shown in Figures 17 through
19. 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 a medium weight (SAE 30) 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.

TIRE PRESSURE
Front and rear tires should be checked periodically to
ensure that proper tire pressure is maintained. Keeping
tires properly pressurized helps provide proper traction,
extend tire life, and improved cut quality.
