SAFE OPERATION PRACTICES-RIDING VEHICLES
28. Allow the engine to cool before storing it in any
enclosure.
29. To reduce fire hazard, keep the engine and
attachments free of grass, leaves or excessive grease.
30. Battery acid is a poison and can cause burns.
Avoid contact with skin, eyes and clothes and protect
your face, eyes and clothing when working around the
battery.
31. Battery gases can explode. Keep cigarettes,
sparks and flames away from battery.
EQUIPMENT USE AND OPERATION
32. We recommend that you first operate the
equipment at a slow speed with any attachment
disengaged until you are thoroughly familiar with the
controls and have developed operating skills.
33. Disengage all attachment clutches, set the
parking brake and shift into NEUTRAL before starting
the engine.
34. Disengage power to the attachment(s), set the
parking brake and stop the engine before leaving the
operator position.
35. Disengage power to the attachment(s) and stop
the engine before making any repairs or adjustments.
36. Disengage power to the attachment(s) when
transporting the machine or when it is not in use.
37. Disengage the attachment clutch before removing
the mower from a hole or other obstruction.
38. Disengage power to the attachment(s) before
backing. Do not mow in reverse unless it is
absolutely necessary and then only after careful
observation of the entire area behind the machine.
39. LOOK behind the machine to make sure the area
is clear before placing the transmission in reverse and
continue looking behind while backing.
40. Always back the machine up loading ramps and
tilt bed trailers.
41. The parking brake is designed to hold the vehicle
in place at rest, with the engine off. The parking brake
will not restrain the vehicle with the engine running
and the transmission engaged.
STABILITY/TIP OVER/TRACTION
42. Know the terrain on which you operate your
equipment. There are areas on which you cannot
safely operate your equipment.
43. Avoid operating the machine on hillsides, slopes
or rough terrain. DO NOT operate the machine on
EN-2
hillsides or slopes exceeding 15° (27% grade). If
safety is in doubt— STAY OFF THE SLOPE.
44. Reduce speed and exercise extreme caution on
slopes above 10° (18% grade) to prevent tipping or
loss of control. Never mow uphill on these
slopes-mow downhill only. If you must climb a steep
hill, back the machine up the hill, and drive the
machine forward down the hill, keeping the vehicle in
gear. If necessary to tum on hill, always turn downhill.
45. Mow up and down the face of slopes greater than
5° (9% grade), never across the face. Be especially
cautious when changing directions on all slopes.
46. Operate your machine smoothly and at a ground
speed slow enough to ensure complete control.
Avoid erratic operation and excessive speed.
47. Sharp turns on any terrain may cause loss of
control. Reduce speed and use caution on sharp
turns.
48. Do not stop or start suddenly when going uphill or
downhill. Avoid uphill starts. If machine stops when
going up a slope, turn the attachment off and back
slowly down the slope, keeping the machine in gear.
Do not stop or change gears (speed) on slopes.
49. Know the terrain. Find hidden obstacles by
walking through and inspecting the area before
operating your equipment in that area. Plainly mark
obstacles, such as rocks, roots or holes and stay well
clear of these obstacles when operating.
50. While operating, stay alert for holes, rocks or
roots, which may damage equipment or cause it to
upset. Keep at least three (3) feet away from
drop-offs, ditches, creeks, culverts, washouts and
public highways.
51. Exercise care when mowing around a fixed object
to prevent the equipment or attachment from striking it.
When mowing, never deliberately run over any foreign
object.
52. Areas wet with dew, rain or snow will be more
slippery than when dry. Areas covered with loose
gravel are more slippery than firm, dry ground.
Greater stopping distances are required in these
slippery areas.
53. Learn to expect changes in operating conditions.
Adding or removing attachments or weight to your
equipment will make your machine operate differently.
Rain, snow, loose gravel, wet grass, etc., change the
terrain’s tractive conditions. Changing tractive
conditions require you to change your operating
technique-including deciding not to operate on that
terrain sometimes.
SAFE OPERATION PRACTICES-RIDING VEHICLES
54. Use care when pulling loads or using heavy
equipment.
A. Use only approved drawbar hitch points.
B. Limit loads to those you can safely control.
C. Do not tum sharply. Use care when backing.
D
Use counterweight(s) or wheel weights when
suggested in the operator's manual.
ATTACHMENT USE
55. When using attachments, never direct the
discharge of material toward bystanders, nor allow
anyone near the vehicle while it operates.
56. When using the machine with a mower:
A. Mow only in daylight or in good artificial light.
B. Never adjust cutting-height while the engine
is running if you must dismount to do so.
C. Shut off the engine when unclogging the
chute.
D. Check the blade mounting bolts for proper
tightness at frequent intervals.
57. Keep hands and feet away from rotating blade(s)
underneath the mower deck. Never place your foot on
the ground when the mower is engaged or in motion.
58. DO NOT operate the mower attachment without
the chute deflector or complete bagger in place.
59. Exercise care while maneuvering with the grass
catcher. Front-to-rear stability may change.
60. If you use the machine with a snowthrower and
the auger becomes plugged or jammed:
A. Declutch the snowthrower and stop the
vehicle engine immediately.
Disconnect the spark plug wire(s).
C. Clear snow from the discharge chute if it is
plugged.
D. If the auger is jammed, remove the foreign
object and repair any damage to snowthrower
before you continue.
E. Reconnect the spark plug wire(s) and resume
operation.
61. Never permit anyone to stand near the
snowthrower auger or discharge opening. Objects
may be present in snow, which when thrown, could
cause injury.
62. When using snow/dozer blades:
A. Do not hit solid objects. This can damage
blades and injure the operator.
B. Always travel at a safe, slow speed.
63. Keep all persons at safe distance away when
operating tillers. Always disengage the PTO, lower
the attachment and remove the ignition key before
making any adjustments.
64. If the tiller starts to push the vehicle, disengage
the PTO clutch immediately.
65. Use chains, counterweight(s) or wheel weights
when necessary.
MAINTENANCE
66. Keep all nuts, bolts, fasteners and screws tight to
ensure the equipment is in safe working condition and
check them frequently. Repair or replace worn,
damaged, distorted or broken parts as needed.
67. Keep the vehicle and its attachments in good
operating condition and keep safety devices in place
and working.
68. Under normal usage, the grass catcher bag's
material will wear and deteriorate. Check often to see
if the bag needs to be replaced.
69. Use only genuine Toro Wheel Horse replacement
parts to maintain original standards.
70. Shields, deflectors, switches, blade controls and
other safety devices must be in their proper position
and functional.
71. Do not operate without a muffler or damper on the
exhaust system. Damaged mufflers or spark arresters
can create a fire hazard. Periodically inspect and
replace whenever necessary.
72. If the equipment begins to vibrate abnormally,
disengage power to the attachments and stop the
engine immediately. Repair any damage before
starting or continuing operation.
73. Periodically inspect all shafts, levers, friction
devices and other moving parts that are subject to
wear. Adjust or replace these parts if they are
damaged, distorted or broken, or when wear affects
the normal operation of the vehicle or attachment. DO
NOT use equipment that is not operating properly.

and electrical circuits. The lights will stay on
momentarily and then go out.
All indicator lights must be OFF during operation; if an
indicator light is on, there is a malfunction that must
be corrected.
When the “AIR FILTER” light comes on, service the
precleaner and air cleaner.
The “SEAT SWITCH” light comes on when the seat is
unoccupied with the ignition switch in the RUN or
START position.
If the "PTO LEVER?” light is on when you try to start
the engine, check that the PTO control lever is in the
correct position for starting.
If the “MOTION LEVER?” light is on during starting,
check that the control lever is in the correct position
for starting.
EN-6
The “HYDRO TEMP” light senses the automatic
transmission and transaxle oil temperature. If the light
comes on, clean the transmission fins and check the
cooling fan.
The “OIL PRESS” light measures engine oil pressure.
This light flashes before the engine is started and

3. VOLTMETER
This gauge shows the electrical system battery
voltage. When you turn the ignition key to RUN, the
gauge should read 12 volts or slightly higher. After the
engine starts, the gauge should read between 12 and
15 volts. If the gauge reads less than 12 volts, the
battery is discharging. If the gauge reads 15 volts for
long periods of time, check the battery water more
often.
INSTRUMENTS AND CONTROLS
4. HORSEPOWER %
This gauge measures the load applied to the engine.
As the load increases, the gauge reading will
increase. The gauge should read between 25 and 75
for normal operation. With the engine running at full
throttle, the load should be reasonably heavy for the
first 25 hours of operation of seat the piston rings.
5. FUEL GAUGE
This gauge shows the fuel level in the fuel tank. Refill
the tank with fuel as the gauge approaches the “E”
marking.
6. TACHOMETER
This gauge measures engine revolutions per minute
(rom). The gauge is actuated only when the ignition
switch is in the RUN position. With the engine running
at full throttle and no load, the gauge should read as
described in the Specifications section of this manual.
If the gauge reads less than specifications, contact
your Authorized Toro Wheel Horse Dealer for service.
7. HOUR METER
This gauge records the tractor's operating hours. it
switches on when the ignition switch is in the RUN
position.
8. PTO (POWER TAKE-OFF) CLUTCH LEVER
The PTO lever engages and disengages the
power-driven attachments. Push the lever forward to
engage an attachment. Pull the lever back to
disengage an attachment.
The PTO clutch lever actuates a safety interlock switch
in the starter circuit. The indicator light comes on and
the tractor will not start unless the lever is in the
DISENGAGED position. If you leave the operator's
seat while the PTO is engaged, the seat switch
indicator light comes on and the seat switch
automatically shuts off the engine.
9. THE MOTION CONTROL LEVER
This lever must be the NEUTRAL position to actuate a
safety interlock switch that will allow you to start the

interlock switch is not actuated when ignition switch is
in the START position.
Move the motion control lever all the way to the right
and push it ahead to move the tractor forward; pull the
lever back to NEUTRAL to stop. Push the lever down
and pull it back to move the tractor in reverse.
The motion control lever varies the ground speed and
pulling power of the tractor independently from the
engine speed. To increase the ground speed, move
the lever away from NEUTRAL. Increase pulling
power by moving the lever toward NEUTRAL .
10. THE PARKING BRAKE LOCK LEVER
To engage the parking brake, first press the foot brake
pedal firmly, then move the parking brake lock lever
back to lock the brake. To release the parking brake,
push down on the foot brake pedal. (The parking
brake lock lever is spring loaded and will return to the
disengaged position when you press the foot brake
pedal.) The indicator light is on when the parking
brake is locked with the ignition switch in the RUN
position.
11. THROTTLE CONTROL
The throttle lever controls the engine speed. Raise the
lever to operate the tractor; lower the lever before
shutting off the engine.
12. THE IGNITION SWITCH
The ignition switch has three positions from the left to
the right; (1) OFF, (2) RUN, (3) START. To start the
engine, turn the key all the way to the right to START.
Release the key when the engine starts; it will
automatically return to RUN. When you turn the switch
to OFF, the engine stops and all electrical accessories

. tank under the rear fender. Normally it is left open,
except when service on the fuel system becomes
necessary.
EN-7
OPERATING YOUR TRACTOR
BEFORE OPERATING
Day: CHECK THE OIL
Check the oil level before each use. The engine is
equipped with a low-oil pressure switch. The Engine
will start and run when the light flashes and oil
pressure is low. However, if the light does flash during
operation, stop the engine immediately and contact
you authorized TORO Wheel Horse dealer.
information about recommended oils and how to
check the oil level is in the Maintenance section of
this manual.
al CHECK THE FUEL
THE TORO COMPANY STRONGLY RECOMMENDS
USING ONLY FRESH, CLEAN UNLEADED REGULAR
GRADE GASOLINE. UNLEADED GASOLINE BURNS
CLEANER, EXTENDS ENGINE LIFE AND PROMOTES
GOOD STARTING BY REDUCING FORMATIONS OF
COMBUSTION CHAMBER DEPOSITS. IF UNLEADED
GASOLINE IS NOT AVAILABLE, LEADED CAN BE
USED. NEVER USE METHANOL, GASOLINE
CONTAINING METHANOL OR MORE THAN 10%
ETHANOL, GASOLINE ADDITIVES, PREMIUM
GASOLINE OR WHITE GAS BECAUSE THE ENGINE
FUEL SYSTEM MAY BE DAMAGED. ALSO, DO NOT
USE GASOLINE DE-ICERS. THEY CAN CAUSE
INTERNAL DAMAGE TO CARBURETOR AND FUEL
PUMP PARTS.
If you use regular leaded gasoline continually, you
should remove carbon and lead deposits from the
cylinder heads as required because of engine power
loss. You can safely use unleaded gasoline after the
lead deposits have been removed.
EN-8
A DANGER
Gasoline is highly flammable, use caution
when storing or handling it.
Do not fill the fuel tank while the engine is
running, hot, or when the machine is in an
enclosed area. Vapors may build up and
be ignited by a spark or flame source
many meters (feet) away.
DO NOT SMOKE while filling the tank.
Always fill the fuel tank outside and wipe
up any spilled fuel before starting the
engine.
To prevent spilling fuel, use a funnel or
spout and fill the tank to about 25 mm
(1 in.) helow the filler hole. DO NOT
OVERFILL.
Use gasoline for the engine only, not for
any other purpose.
Store gasoline in a clean, safety approved
container and keep the container capped.
Keep gasoline in a cool, well-ventilated
place. Never store gasoline in an
enclosed area such as a hot storage
shed.
Never buy more than 30 days’ supply to
assure volatility.
Because many children like the smell of
gasoline, keep it out of their reach
because the fumes are explosive and
dangerous to inhale.
CHECK THE SAFETY INTERLODCK
SYSTEM
The safety interlock system incomorates tree
switches for sate starting,
nese starting switches are actuated by the motion
control lever, the PTO clutch control and the seat, if
the tractor won't start, check whether ihe seat is
occupied, the PTO clutch is disengaged and the
motion control lever is in the NEUTRAL position. The
indicator lights will be on and the engine will not stan
unless all three switches are actuated.
This switch shuts off the engine when you rise off the
seat while the PTO is engaged.
Test the safety interiock system periodically. To test it,
coserve the following functions, (rar your protection,

STARTING THE ENGINE
CAUTION
Sefore starting the engine, become famillar
with all controls. Read this manual
thoroughly. Also, slways check he engine's
ofl level before starting.
WARMING
Take care to avoid inhaling exhaust gases
Because they contain carbon monoxide gas,
which is colorless and odorless. Carbon
monoxide is a dangerous gas that can cause
unconsciousness and death. Do NOT run the
engine in confined areas such as a closed
garage.
Your tractor will not start until the motion control lever
is in the NEUTRAL position, the PTO is disengaged
and the seat is occupied. The indicator light(s) will
glow if the controls are not in the correct position for
starting.
OPERATING YOUR TRACTOR
To start the engine, position the motion control lever in
NEUTRAL and disengage the PTO. Move the throttle
control lever to the SLOW position. Raise the choke
control all the way to the COLD position.
Turn the ignition key clockwise until the starter
engages. When the engine starts, release the key.
The switch is spring loaded and will return to RUN
automatically.
IMPORTANT: If the engine fails to start after 30
seconds of continuous cranking, turn the key to
OFF and allow the starter motor to cool. Check for
the cause of hard starting; consult the
Troubleshooting Check List.
After the engine starts, move the throttle to half
position and slowly return the choke control to its
normal position. If the engine stalls at low speeds or
hesitates during acceleration, use the choke until the
engine reaches normal operating temperature.
(The choke controls a “butterfly” valve in the
carburetor. When the choke is partially or completely
closed, less air is admitted to the engine, resulting in
a higher fuel-to-air (richer) mixture that is easier to
ignite when the engine is cold. Choking the engine is
needed if it is started cold. Warm engines may not
need choking.)
When starting the engine during cold weather, follow
the special procedures for warming the engine and
transmission described under “Operating the
Automatic Transmission.”
USING THE THROTTLE CONTROL
The throttle control regulates the engine speed as
measured in RPM (Revolutions Per Minute). This
control should not be used to regulate the tractor's
ground speed.
Always operate the tractor with the throttle control set
at full speed. The engine has a special governor that
limits maximum RPM. This allows the engine to
operate most efficiently at a set speed and protects it
from damage caused by excessive RPM.
IMPORTANT: The engine must operate at full
throttle whenever you use the tractor. Operating at
less than full throttle may result in extensive
transmission damage and poor tractor
performance.
EN-10
GOING FORWARD OR BACKWARD
IMPORTANT: During cold weather, start the engine
with the parking brake engaged and allow the
transmission to run in NEUTRAL for 5 minutes
before setting the unit into motion. For
temperatures below 0° F (-18° C), allow the
transmission to run in neutral for 10 minutes before
beginning motion. Failure to do so may result in
extensive transmission damage.
To Go Forward
A CAUTION
Before the tractor will move forward or
backward, the parking brake must be
disengaged. ALWAYS depress the brake/
return to neutral pedal when disengaging
parking brake.
A single “Motion Control Lever” controls your tractor’s
motion. To go forward, move the lever forward. The
farther forward you push the lever, the faster the tractor
will go.
A CAUTION
For safe operating, never move the motion
control lever too rapidly, especially on grades.
By adjusting the motion control lever, you can regulate
the tractor’s forward speed without adjusting the
throttle control. For heavy pulling, moving the control
lever toward NEUTRAL reduces the tractor ground
speed and increases pulling power, just as shifting to
a lower gear does with a mechanical transmission.
To Go Backward
To go backward, return the motion control lever to
NEUTRAL and pull the lever back. The farther back
you pull the lever, the faster the tractor will go in
reverse.
A CAUTION
For safety, never move the motion control
lever too rapidly, especially on grades.
By adjusting the motion control lever, you can regulate
the tractor’s reverse speed without adjusting the
engine throttle control.
OPERATING YOUR TRACTOR
STOPPING
You can stop the tractor by one of two methods:
1. Retum the motion control lever to its NEUTRAL
position.
2. Press the brake pedal.
Pressing the brake pedal automatically returns the
motion control lever to its NEUTRAL position and
applies a mechanical brake. The brake pedal will
hold the motion-control lever in NEUTRAL. (The
pedal must be released before you can move the
motion control lever either forward or backward.)
Tractors are free to roll (at a very slow speed) when
the transmission is in NEUTRAL. Therefore, always
depress brake pedal when the tractor is stopped on
unievel terrain.
SHUTTING OFF THE ENGINE
To shut off the engine, return the throttle lever to the
idle position and turn the ignition key to OFF. if the
engine has been working hard or is hot, allow it to idle
a short time before turning off the key. This will help
cool the engine before stopping.
Note: in an emergency, the engine may be stopped
by tuming the ignition key to the OFF position.
A CAUTION
Always remove the key and set the parking
brake when leaving the tractor unattended,
even if just for a few minutes. Prevent
accidents; don’t give children or unauthorized
persons an opportunity to operate this
machine.
HAND PUSHING THE TRACTOR
IMPORTANT: Hand push the tractor oniy-do not
tow. Towing can damage the hydrostatic
transmission severely.
Automatic transmission tractors can be pushed at a
slow speed. To do this, move the motion control lever
fully forward; the tractor will then move when pushed.

Because of your fracior’s engine power, you should
not encounter any problems using attachments under
normal conditions. Tne front wheel weights may be
used to increase front-wheel traction. Rear wheel
weights and tire chains may also be used to increase
rear-wheel raction. Front and rear tires may be fluid
filled.

NTS
For best operation on average lawns, operate the
engine at full throtile while controlling the ground
speed with the transmission. Operate the tractor at 2
to 3.5 MPH (3.2 10 5.8 KMH)* while mowing grass.
Uneven cutting is offen a result of excessive ground
speed. To eliminated uneven culling, reduce ground
speed.
Usually lawns are cit at heights between 2 and 3 in.
(5 - 7.6 om). Tall grass and weeds should be cut with
the mower at its highest position, making a
second-pass cutting at the height desired.
Always keep the mower blades sharp.
CAUTION
Sharp edges or mower biades can cut you
during blade maintenance or adjustment. Use
a suitable covering over the blade's cutting
edges to prevent bodiy narm.
USING A SNOWTHROWER
mt
TION
Thoroughly inspect ihe area where you will
use the snowihrower. Remove all door mats,
sleds, boards and other foreign objects,
Mever make any adjustments while the engine
is running. Never try to clear the chute while
the engine is running.
Snow removal operation will vary greatly with the
condition of each snowfall. Light fluffy snow can be
cleared with ease. Clearing heavy wet snow may be
more difficult. Coating the auger and chute with a
light coat of wax or paraffin will help keep snow from
sticking. Best results usually occur when the tractor
ground speed is set at 110 2 mph (1.6 10 3.2 kmh.)
Note: Average walking speed is 3.5 mph (4 kmh).
Note: Inflate the front tires to 20 psi (138 kPa) for use
with ihe two-stage snowihrower
Exercise care whenever using the snow thrower. The
auger can pick up sticks, stones and other foreign
objects and inrow them with great velocity. Always
aim the discharge chute away from persons or objects
that might be harmed.
Tire chains and wheel weights are recommended
when using a snowinrower.
EN-13
USING YOUR TRACTOR WITH ATTACHMENTS
USING A SNOW, DOZER OR GRADER
BLADE
Although the front-end dozer blade is usually used for
snow removal, it can also be used for moving dirt,
sand or gravel. Be careful and maintain a slow
ground speed whenever you use the blade. Striking a
solid object could injure you and damage the blade.
Grader blades are usually preferred for leveling sand,
dirt or gravel. Using these blades is similar to using a
dozer blade. Rear-mount grader blades may require
special hitches; consult your dealer for the proper
hitch(es) for your tractor.
USING A TILLER
The TORO Wheel Horse tiller does an excellent job of
preparing gardens for planting.
Exercise caution when tilling virgin ground or clay
because the tiller may have a tendency to push the
tractor. You can correct this by raising the tiller with
the attachment lift so the tiller penetrates only the very
top of the soil. You can then lower the tiller to its full
depth on later passes. Cleat tires will reduce the
tiller’s pushing effect.
A CAUTION
If the tiller starts to push the tractor, shut the
tiller off immediately by disengaging the PTO
clutch.
Slowing the tractor's ground speed will improve the
tiller’s aggressive action. Best results usually occur
with a tractor ground speed of less than 1.0 mph
(1.6 kmh).
Note: Average walking speed is 2.5 mph (4 kmh).
Do not over-till soil. Soil tilled excessively will not
hold water and will compact easily.
USING A PLOW, DISC, CULTIVATOR OR
HARROW
Plows and discs require maximum tractor efficiency.
Cleat tires, or tire chains, and wheel weights increase
rear tire traction. Front-wheel weights increase
steering control.
Some attachments require special rear hitches.
Consult your dealer for proper hitch(es) required for
your tractor.
EN-14
There are two methods of preparing a seed bed for
planting.
1. Use a tiller, which will prepare the soil in one
operation.
2. Use a plow to turn ground, a disc to break up
large clumps, and a harrow to pulverize and smooth
soil.
Plows are classified by the width of the furrow they
tum. Generally, plows are set to cut 4 to 6 in.
(10-15.2 cm) deep.
A disc is used immediately after plowing. The disc
will break up large clumps of soil.
After discing, a spike-tooth harrow is usually dragged
over soil. The harrow helps pulverize the soil and
levels the seed bed. The soil should now be ready for
planting.
A cultivator is used during growing season to help
remove unwanted weeds and to help aerate plant
roots. Consider the cultivator’s width before planting
the seed bed to ensure the cultivator will fit between
rows without damaging crop roots.
USING OTHER ATTACHMENTS
Many other special-purpose attachments are
available that greatly increase the tractor’s versatility.
An attachment can be a completely self-contained
system (front bucket loader), one that is used with
another attachment (lawn vacuum), or one intended for
operator comfort (snow cab).
Some attachments are powered by a separate
gasoline engine, some are ground driven and some
are simply towed, such as a dump cart.
All attachments should be approached with the same
caution given any mechanical device. Always read
each Operating Instruction Manual carefully before
using the attachment. Keep children and pets away
from the vehicle when it is operating. Never allow any
unauthorized personnel to operate the equipment.
Your authorized TORO Wheel Horse dealer can help
you with selecting attachments for use with your
tractor.
DUMP CART LOAD LIMITS
Observe the following load limits when using the
tractor with a dump cart. Load limits have been set to
provide for safe braking on slopes.

MAINTENANCE
A CAUTION
To minimize chance of injury, do all maintenance and adjustments on your tractor with the engine off
and the ignition key removed, unless instructed otherwise. Use extreme care when working near
operating machinery. Do not wear loose fitting clothing. Remove your watch and any jewelry before
beginning work and observe common safety practices when using tools.

IMPORTANT: Never overfill the engine crankcase
with oil. The oil level must not exceed the “F” level
on the dipstick.
CLEANING THE AIR FILTER
Dirt coming through improperiy installed, poorly
serviced, or inadequate air filter elements is very
harmful to the engine. Also, a clogged element
causes a richer fuel mixture, which wastes gasoline
and may lead to formation of harmful sludge deposits.
If the tractor has an AIR FILTER indicator light, clean
the air filter and precleaner when the light comes on
during operation.
If the engine does not have an AIR FILTER indicator
light, clean the engine air filter and precleaner after
every 25 hours of operation (more often if you operate
the machine in extremely dusty conditions).
Replace air filter elements at 200~hour intervals.
Replace them more often in dusty operating
conditions. To protect your engine, use only the
manufacturer's replacement filter or replacement filters
with equivalent specifications.
Check the following when installing a new or serviced
element:
1. The base must be tightened securely to the
carburetor. Replace the base if it is bent or cracked.
2. Gasket surfaces of the element must be flat
against the base and cover to seal effectively.
3. Tighten screws securely.
4. Be sure cover seals and gaskets are in good
condition and will seal properly. Bad gaskets and
seals can [et unfiltered air into the carburetor.
IMPORTANT: To prevent any dirt or other
contaminants from entering the engine, always
cover the carburetor air horn when you remove the
air cleaner.

Clean the dry-type air filter element by tapping i
lightly on a flat surface to remove loose dint particles.
Replace the element if dirt does not drop off easily.
DO NOT wash elements in liquid. Do not attempt to
blow dirt off with compressed air because this can
puneture the filter element.
Foam precieaners are used over the filter elements on
the air cleaner. Clean the precieaner at 25-hour
intervals, when servicing the air cleaner. Wash the
precieaner in a solution of liquid dishwashing
delergent and water. Squeeze oul excess water and
allow it io dry. Coat the precieaner evenly with two
tablespoons of SAE 30 engine oil, kneading the oil
into the precieaner. Wring out excess oil from the
precieaner, then install the precleaner over the air
cleaner element. In other words:
1. WASH
2. SQUEEZE DRY
3. COAT WITH OIL-WRING OUT EXCESS
4. INSTALL OVER PAPER ELEMENT
CRANKCASE BREATHER
The engine uses a crankcase breather valve and
“Pack” for maintaining the crankcase vacuum. If the
crankcase becomes pressurized as evidenced by ой
leaks at the seals, clean the pack and valve screens
in a suitable solvent. Check and clean the valve and
