ment be done at a slow speed with attachment
disengaged. Continue this practice until operator
is thoroughly familiar with the controls and has
developed operating skills.
Disengage all attachment clutches, set parking
brake and shift into neutral before attempting
to start engine.
Disengage power fo attachment(s), set parking
brake and stop engine before leaving operator
position.
Disengage power to attachment(s) and stop en-
gine before making any repairs or adjustments.
Disengage power to attachment(s) when trans-
porting or not in use.
Disengage attachment clutch before attempting
to remove the mower from a hole or other ob-
struction.

Know the terrain on which you are operating
your equipment. There are areas on which your
equipment can not be safely operated.
Avoid operating equipment on hillsides, slopes
or rough terrain. DO NOT operate machine on
hillsides or slopes exceeding 15° (27% grade).
If safety is in doubt — STAY OFF THE SLOPE.
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 a steep hill must
be ascended, back up the hill, and drive forward
down the hill, keeping tractor in gear. If neces-
sary to turn on hill, always turn downhill.
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.
Operate your machine smoothly and at a ground
speed slow enough to insure complete control
at all times. Avoid erratic operation and exces-
sive speed.
Sharp turns on any terrain may cause loss of
control. Reduce speed and use caution when
making sharp turns.

Do not stop or start suddenly when going uphill
or downhill. Avoid uphill starts. If machine is
stopped 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.
Know the terrain on which you are working. Find
hidden obstacles by walking through and inspect-
ing the area prior to operating your equipment
in that area. Plainly mark obstacles, such as
rocks, ruts or holes and stay well clear of these
obstacles when operating.
While operating, stay alert for holes, rocks or
roots, which may cause damage to equipment or
upset. Keep at least 3 ft. away from drop-offs,
ditches, creeks, culverts, washouts and public
highways.
Exercise care when mowing around a fixed ob-
ject to prevent the equipment or attachment from
striking the object. When mowing never deliber-
ately run over any foreign object.
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.
Learn to expect changes in operating conditions.
Adding or removing attachments or weight to
your equipment will make your machine perform
differently. Rain, snow, loose gravel, wet grass,
etc., change the tractive conditions of the terrain
requiring changes in your operating technique,
which may include a decision not to operate on
that terrain.
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 turn sharply. Use care when backing.
D. Use counterweight(s) or wheel weights when
suggested in operator's manual.
ATTACHMENT USE

When using attachments never direct discharge
of material toward bystanders nor allow anyone
near vehicle while in operation.
When using machine with mower:
A. Mow only in daylight or in good artificial
light.
B. Never make a cutting height adjustment while
engine is running if operator must dismount
to do so.
C. Shut engine off when unclogging chute.
D. Check blade mounting bolts for proper tight-
ness at frequent intervals.
Keep hands and feet away from rotating blade(s)
underneath mower deck. Never place foot on
ground when mower is engaged or when mower
is in motion.
DO NOT operate mower attachment without the
chute deflector or complete bagger in place.
Exercise care while maneuvering with grass
catcher. Front to rear stability may change.

When using machine with snowthrower and aug-
er becomes plugged or jammed:
A. Declutch snowthrower and stop tractor en-
gine immediately.
B. Disconnect spark plug wire(s).
C. Clear snow from discharge chute if plugged.
D. If auger is jammed, remove foreign object
and repair any damage to snowthrower be-
fore continuing.
Reconnect spark plug wire(s) and resume
operation.
m
Never permit anyone to stand near snowthrower
auger or discharge opening. Objects may be
present in snow, which when thrown, could cause
injury.
When using snow /dozer blades:
A. Avoid hitting solid objects. This can dam-
age blade and injure operator.
B. Always travel at a safe, slow speed.
Keep all persons a safe distance away when
operating tillers. Always disengage the PTO, low-
er the attachment and remove the ignition key
before making any adjustments.

Keep all nuts, bolts, fasteners and screws tight
to be sure equipment is in safe working condi-
tion and check them frequently. Repair or replace
worn, damaged, distorted or broken parts as
needed.
Keep vehicle and attachments in good operating
condition and keep safety devices in place and
working.
Under normal usage, grass catcher bag material
is subject to deterioration and wear. It should be
checked frequently to determine need for bag
replacement.
Use only genuine Wheel Horse replacement parts
to assure that original standards are maintained.
Shields, deflectors, switches, blade controls and
other safety devices must be in their proper po-
sition and functional.
Do not operate without muffler or tamper with
the exhaust system. Damaged mufflers or spark
arresters can create a fire hazard. Periodically
inspect and replace if necessary.
If equipment begins to vibrate abnormally, dis-
engage power to attachments and stop engine
at once. Repair any damage before starting or
continuing operation.
Periodically inspect all shafts, levers, friction de-
vices and other moving parts subject to wear.
Make required adjustment or replace these parts
if damaged, distorted or broken, or as soon as
wear affects the normal operation of the vehicle
or attachment. DO NOT operate equipment that
is not functioning properly.

OPERATING YOUR MACHINE
SAFETY INTERLOCK SYSTEM
TEO
gs Fy
SAFETY INTERLOCK SWITCHES
Each machine has two interlock switches for
safe starting and a seat switch that shuts engine
off when driver raises off seat. PTO switch must
be "OFF" and parking brake engaged before
engine will start. Seat switch will stop engine when
seat is vacated with PTO switch in "ON" position,
or if parking brake is not set.
If machine will not start, check that parking brake
is engaged and PTO switch is in “OFF” position.
Safety interlock system must be tested periodi-
cally. To test operation, following functions must
be observed. If not, immediate repairs must be
performed by an Authorized Wheel Horse Dealer
for your protection.
1. Engine should NOT start if:
a. Parking brake is disengaged.
b. PTO switch is “ON”.
Test each of the above - one at a time.
2. With engine running and PTO switch in “ON”
position, test operate seat switch by rising off
seat. Engine should shut off.
3. With engine running, PTO "OFF" and parking
brake disengaged, test operate seat switch
by raising off seat. Engine should shut off.
SEAT ADJUSTMENT
Seat can be adjusted for optimum operator
comfort.
1. Loosen two knobs.
2. Slide seat to desired position.
3. Tighten knobs.

CORRECT ENGINE OPERATION
A CAUTION À
Before starting engine, become familiar
with all controls. Read this Operator's
Manual thoroughly. Always check engine
oil level before starting engine.
/\ DANGER A\
Care should be taken to avoid inhaling
exhaust gases as they contain carbon mon-
oxide gas which is colorless and odorless.
Carbon monoxide is a dangerous gas that
can cause unconsciousness and is poten-
tially lethal. Do not run engine in confined
areas such as a closed garage.
Starting Engine
Because of a built-in safety interlock system,
your machine will not start unless parking brake is
engaged and PTO switch is “OFF”.
To start engine, engage parking brake. Move
throttle control lever to low idle position. Pull
choke control all the way out to Cold position. Turn
ignition key to Start position to engage starter.
When engine starts, release key. Switch is spring
loaded and will return to Run position automati-
cally.
IMPORTANT
If engine fails to start after 10 seconds of
continuous cranking, turn key to OFF posi-
tion and allow starter motor to cool. Check
for cause of hard starting; consult Trou-
bleshooting Checklist.
Once engine has started, raise throttle to half
position and lower choke. If engine stalls at low
speeds, or hesitates during acceleration, choke
should be applied as necessary until engine
reaches normal operating temperature.
Stopping Engine
To stop engine; move throttle lever to Idle posi-
tion and turn ignition key to "Off" position. If
engine has been working hard or engine is hot,
allow engine to idle a short time before turning key
off. This practice will help cool engine before
stopping.
Note: In case of emergency engine may be
stopped by turning ignition key to "Off" position.
AN CAUTION A
Always remove key and set parking brake
when leaving machine unattended, even If
for Just a few minutes. Prevent accidents;
don’t give children or unauthorized per-
Sons an opportunity to operate this ma-
chine.
Throttle Control
Throttle control regulates speed of engine as
measured in RPM (Revolutions Per Minute). This
control Should not be used to regulate ground
speed.
Engine has been designed with a special gover-
nor that limits engine RPM. Unlike an automobile,
this governor allows engine to operate most effi-
ciently at a set speed and protects it from damage
caused by excessive RPM. Always operate ma-
chine with throttle control set at full speed.
Choke Control
Choke control activates a “butterfly” valve in
carburetor. When choke is partially or completely
closed, less air is admitted to engine. This results
in a higher fuel-to-air (richer) mixture that is easier
to ignite when engine is cold. Choking engine is
required when engine is started cold. Warm
engines may not need choking.
Fuel Recommendations
A DANGER A
Ignition of fuel can cause serious personal
injury or death by fire or explosion. Do Not
permit any flame, cigarette, or other igniter
near fuel system. Handle fuel with care - it
is highly flammable.
Use clean, fresh, unleaded gasoline. Regular
leaded gasoline may also be used, but is not a
preferred fuel. Do not use highly leaded premium
gasoline. Use of unleaded gasoline results in less
maintenance.
IMPORTANT
Do not use gasoline de-icers. Gasoline
de-icers can cause internal damage to car-
buretor and fuel pump parts. Do not use
fuels containing ethanol concentrations
greater than ten percent. Fuel containing
alcohol may cause poor engine perform-
ance and Internal engine damage.
If regular leaded gasoline is used continually,
carbon and lead deposits should be removed from
cylinder heads as required because of engine
power loss. Unleaded gasoline may be used
safely after lead deposits have been removed.
ZN DANGER À
Spilled fuel can ignite and cause serious
personal injury or death. Never fill fuel tank
when engine is running. Fill fuel tank out-
doors with extreme care. Never fill fuel tank
indoors. Replace gasoline cap securely
and wipe up all spilled fuel.
Oil Specification
To protect your machine's engine check engine
oil level before each use. Complete information
concerning recommended oils and how to check
oil level is given in “Maintenance” section of this
manual.
CORRECT TRANSMISSION OPERATION
Machine is equipped with a separate transmis-
sion for each rear wheel. Transmissions are
controlled with "Motion Control Levers”, one for
each wheel.
Motion control levers vary forward and rearward
ground speed of each wheel independently. Lev-
ers are in neutral position at mid-way travel of
levers. Levers are spring loaded and will return to
neutral when released. When motion control
levers are moved from neutral to outside of ma-
chine, they are in park (locked) position.
To maintain enough power for machine traction
and mowing, regulate motion contol levers to
keep engine rpm high and somewhat constant. A
good rule to follow is: decrease ground speed as
load on cutting blades increases ro more traction
is required and increase ground speed as condi-
tion decreases. This allows engine, working with
transmissions, to allow proper ground traction
while maintaining high blade tip speed necessary
for good quality-of-cut.
/\ CAUTION А\
Always move motion control levers slowly.
Sudden starts can be damaging to equip-
ment and could cause loss of operator con-
trol, roll-over or personal injury.
To Go Forward or Reverse
To enter seat, move motion control levers to
park position. Make sure parking brake is set and
start engine. Move levers to neutral position and
release parking brake. Slowly move both levers in
direction you want to go evenly. Farther levers
are moved away from neutral, faster machine will
travel.
To Change Direction
To change direction of machine, slowly move
levers to neutral and slowly move both levers in di-
rection you want to go.
To Make a Gradual Turn
Slow machine down by moving levers toward
neutral evenly. Slightly slow down speed of left
wheel to turn left or slightly slow down speed of
right wheel to turn right.
To Make a Zero Turn
Move both motion control levers evenly to neu-
tral. Slowly move one wheel forward and opposite
wheel rearward atthe same time. Practice turning
in a low visibility hard surface area before trying to
turn on a lawn surface.
To Stop
To stop machine, return both levers evenly to
neutral position. To dismount machine, set park-
ing brake, move motion control levers to park
position, shut-off engine and dismount machine.
Transmission Push Valve Levers
HAND PUSHING MACHINE
IMPORTANT
Hand push machine only. Do not tow. Towing
can cause severe damage to transmission.
Machine can be pushed at a slow speed. Trans-
mission push valves are located under main frame
in front of rear wheels. To release push valves in
each transmission, lift levers up and to the right
into lock positions. To resume operation of ma-
chine, release levers so that levers are in lowered
position.
CORRECT MACHINE USAGE
ZA CAUTION A
Read manuals provided with attachments
before operating. These manuals give a
detailed description of operation and point
out other areas of caution. Familiarize
yourself thoroughly with equipment before
attempting to use it.
OPERATION OF MACHINE:
WITH MOWER
IMPORTANT
Keep all shields and mower discharge
chute in place. Never attempt to clear
discharge areas or mower blades without
disengaging mower and removing ignition
key.
IMPORTANT
Each time mower is installed, check for
proper operation of PTO clutch and brake.
For best operation on average lawns, operate
engine at full throttle, control ground speed with
transmission. Uneven cutting is often a result of
excessive ground speed. To correct, reduce
ground speed. Average lawns are usually cut at
a height between 2 and 3 in. (5-7.6 cm). Tall grass
and weeds should be cut with mower in its highest
position, making a second pass cutting to height
desired. Always keep mower blades sharp.
Mowing Speed
Mower is designed to operate most efficiently at
maximum blade speeds. Speed of machine should
allow mower blades to maintain this maximum
speed while mowing across turf. Slow machine
for cutting tall grass, grass which is heavy with
moisture, or when moving uphill. If ground speed
is too fast, or blade speed is too slow, mowing will
be uneven because mower blades will not be able
to lift grass into cutting position as mower passes
over ground.
Mowing Height
Best cutting height for your lawn has probably
been established from previous experience. First
time you mow, set mower to cut a little higher than
you have in the past. This will help you determine
best approach to uneven areas, to be sure wider
cut does not result in scalping high spots.
When cutting very tall or damp grass, set mower
inits highest cutting position and enter area slowly.
If necessary, take a cut on half width of mower,
overlapping previously cut area on each pass.
Then, with mower set to desired height, make a
finish cut over entire area.
Mowing Pattern
Machine will cut an area quickly and efficiently if
mowing pattern is planned to take full advantage
of machines capabilities. Use a pattern that will
permit as much continuous forward motion and
long straight runs as possible. Avoid necessity of
repeated tight turns whenever you can by swing-
ing wide over previously cut areas at ends of each
pass. Progressive system illustrated below can be
used on most lawns and eliminates tight turns and
constant direction changes. Leave tight corners
and close trimming until last.

Efficient Mowing Pattern
WITH DRAWBAR TYPE ATTACHMENTS
Many attachments simply use machine as a
towing vehicle. They are attached or removed
from machine by installation or removal of a single
drawbar hitch pin.
Some of these attachments are powered by a
separate gasoline engine, some are “ground
driven”, such as a lawn sweeper. Some are simply
towed, such as a lawn roller or dump cart.
In any case, all these attachments should be
approached with same amount of caution given
any mechanical device. Always read each “Oper-
ating !nstruction Manual” carefully before attempt-
ing to use attachment. Keep children and pets
away from machine when in operation. Never
allow any unauthorized personnel to operate equip-
ment.
A CAUTION A
TORO Wheel Horse recommends follow-
ing load limits be observed when using
machine with a dump cart. Load limits have
been set to provide for safe braking on
slopes.

Air Filter
Dirt induced through improperly installed, poorly
serviced, or inadequate air filter elements, is more
often cause of a worn out engine than long hours
of operation. A small amount of dirt will destroy a
set of piston rings in a matter of hours. A clogged
element causes aricher fuel mixture which wastes
gasoline, and may lead to formation of harmful
sludge deposits.
Clean engine air filter after every 25 hours of
operation (more often if machine is operated
under extremely dusty conditions).
Replace filter elements at 200 hour intervals.
Replace more frequently in dusty operating con-
ditions. To protect your engine, use only manufac-
turer’s replacementfilter, or replacement filter with
equivalent specifications.
Check following when installing a new or serv-
iced element:
1. Base must be securely tightened to carburtor.
Replace base if bent or cracked.
2. Gasket surfaces of element must be flat
against base and cover to seal effectively.
. Tighten screws securely.
. Be sure cover seals and gaskets are in good
condition. Bad gaskets and seals can let in
unfiltered air into carburetor.
> D
IMPORTANT
To prevent any dirt or other contaminates
from entering engine, always cover carbu-
retor air horn when air cleaner is removed.
Dry type air filter element is cleaned by tapping
it lightly on a flat surface to remove loose dirt
particles. Replace element if dirt does not drop off
easily. DO NOT wash elements in liquid. DO NOT
attempt to blow dirt off with compressed air as this
can puncture filter element.
Foam precleaners are used over filter elements.
Clean precleaner at 25 hrs. Wash precleaner in a
solution of liquid detergent and water. Squeese
out excess water and allow it to dry. Coat pre-
cleaner evenly with SAE30 oil. Knead into and
wring out excess oil from precleaner.

Spark Plug
Engine misfires, or generally poor operation, is
often caused by spark plugs in poor condition or
incorrect spark plug gap setting. Replace spark
plugs at 100 operating hour intervals. Also re-
place spark plugs if inspection reveals fouling or
excessive deterioration.
Always clean area around spark plugs before
removing them to prevent dirt from entering en-
gine. Use a spark plug wrench to remove and
install plugs.
Check condition of plug(s). Good operating
conditions are indicated by a light coating of gray
or tan deposit. A dead white, blistered coating
could indicate engine overheating. A black coat-
ing could indicate an “overrich” fuel mixture caused
by a clogged air cleaner, or improper carburetor
adjustment.
Replace spark plugs that are not in good condi-
tion. Never sandblast, wire brush, scrape or
otherwise service a spark plug in poor condi-
tion. Bestresults are obtalned witha new plug.
Always check spark plug gaps before installing
a new plug or reinstalling original plug. Use a
spark plug gap gauge to adjust electrode air gap.
Refer to Specifications section for settings.
Carburetor Adjustment
Carburetors are adjusted at factory and should
not have to be reset. |f however, one of following
conditions is noted, carburetor should be read-
justed immediately as continued operation with
incorrect setting can lead to fouled spark plugs,
overheating, excessive valve wear or other prob-
lems. If black exhaust smoke is noted, check air
cleaner first - an “overrich” mixture is usually
caused by a poorly serviced, clogged air cleaner
element, not an improperly adjusted carburetor.
CONDITION
A. Black, sooty exhaust smoke, engine
sluggish.
B. Engine misses and backfires at high
speed.
C. Engine starts, sputters and dies under
cold weather starting.
D. Engine runs rough or stalls at idle
speed.
Carburetor Adjustment Chart
Correct carburetor adjustment requires a signifi-
cant amount of knowledge as well as special
equipment. In addition, other adjustments, such
as governor settings, may also be necessary after
adjusting carburetor. For these reasons, it is
suggested that carburetor adjustments be per-
formed by an authorized Wheel Horse dealer.
Fuel System
A fine-mesh screen type strainer, incorporated
into fitting at bottom of fuel tank filters foreign
matter from gasoline before it reaches carburetor.
This strainer requires service only if fuel supply
becomes severely contaminated.
Fuel Strainer
-13-
Always clean area around fuel cap before re-
moving it to prevent dirt from entering fuel system.
Also insure that fuel storage container you are
using is clean and in good condition.
Keep fuel tank full during winter operation, cold
and damp weather conditions can cause moisture
to condense in tank.
Exhaust System
Make regular visible and audible inspections of
exhaust system throughout life of machine. Lo-
cate leaks in muffler and piping while engine is
operating. Repair all leaks immediately after they
are detected for personnel safety.
ZA DANGER AN
DO NOT inhale exhaust gases. Exhaust
gases can result in serious personal injury,
even death. Inspect exhaust system for
leaks immediately.
CHARGING AND ELECTRICAL SYSTEMS
Alternator
An alternator is used to charge battery. Alterna-
tor charging system normally requires no service
other than periodically checking that all exposed
wiring and electrical connections on machine are
clean, tight and in good condition.
IMPORTANT
Proper polarity is critical with an alterna-
tor equipped charging system. Always dis-
connect battery ground cable (negative)
before working on any part of electrical
system. Verify all components are con-
nected correctly before reconnecting
ground cable (negative) or damage to alter-
nator system components will result. Never
run engine if battery is removed, of if battery
Is not connected to charging system. Seri-
ous damage to voltmeter and charging sys-
tem components may result.
ELECTRICAL SYSTEM
Fuses
Three fuses protect machines electrical system
and components from excessive current and short
circuits.
Fuses are contained in a fuse holder clipped to
machine's frame under seat:
10 amp fuse protects clutch & hour meter.
20 amp fuse protects switch circuit.
30 amp fuse protects
Fuse Locations
A “blown” fuse is an indication of short circuits or
currentoverloads. Refer to wiring diagram in back
of this manual and become familiar with machine's
electrical system before attempting to trouble-
shoot.
Battery
AN CAUTION /A
When servicing battery or any other part of
electrical system, or if battery must be re-
moved for any reason, always disconnect
negative (ground) cable FIRST and recon-
nectitLAST to avoid possibility of electrical
shorts.
Batteries produce flammable hydrogen
gas. Avoid creating sparks and open flames
and do not smoke when woking near batter-
ies.
Battery electrolyte solution is poisonous
and can be injurious to eyes, skin and
clothing. In event of an accident, flush
affected area immediately with a solution of
one part baking soda to four parts water.
Notify physician immediately. If baking
soda is not immediately available, flush
affected area with water. Notify physician
immediately.
Maintain electrolyte level above plates in each
cell by adding distilled water as necessary. Best
-14-
time to add water is just prior to operating machine
so water will mix with solution. Do not overfill
battery. Electrolyte solution is corrosive and
overfilling can cause damage to surrounding metal
parts. Battery should be maintained at 1.265
specific gravity charge. When battery has been
out of machine for servicing, take care to connect
cables to battery exactly as they were before
removal.
For longest service life, battery should be kept
clean by wiping it off with a paper towel. Any
corrosion around battery terminals should be re-
moved by applying a solution of one part baking
soda to four parts water. A light coating of grease
may be applied to all exposed terminal surfaces to
prevent corrosion.
IMPORTANT
At temperatures below 32°F (0°C), full
charge state must be maintained to prevent
cell electrolyte from freezing and causing
permanent battery damage.
HYDROSTATIC TRANSMISSION
Each rear wheel is controlled by a separate
transmission. Lubricant level in both reservoirs
should be checked before each use. Check oil
levels when oil is COLD. Transmission oil level
should be at line on reservoir.
IMPORTANT
Use care to prevent dirt, clippings or other
foreign material from entering transmis-
sion during oil level checks, oil fillings, or
oil changes.
Changing oil in transmissions is not recom-
mended except for major service. If oil must be
frequently added, a leak is indicated and should
be corrected immediately.
For information purposes, oil capacity for each
transmission is 1.5 gt. (1.4 1)
Oil specifications are:
SAE 30 A.P.l. Service SC,SD,SE,SF
Transmission Oil Level
Cooling Fans
A cooling fan is bolted to each transmission input
shaft. Fan forces air over transmission cooling fins
to cool transmission oil. Replace cooling fan if it
becomes cracked or broken., Be sure to install it
so that maximum airflow is directed across trans-
mission.
Cooling fins on transmissions should also be
kept clean for best cooling efficiency. Periodically
inspect for dirt buildup, and brush or wash out any
accumulated dirt or clippings. If pressure washing
equipment is used, avoid directing spray at joints
and seal areas, to prevent forcing water into
reservoir system.
LUBRICATION

Grease Fittings
Lubricate all grease fittings after each 25 hours
of operation with #2 multi-purpose lithium base
grease using a pressure grease gun. Other
-15-
pivoting arms and levers should be lubricated at
same intervals with light machine oil applied di-
rectly to wear surfaces. Before applying grease
gun, clean zerk fittings carefully to prevent dirt
from being forced into fitting. After inserting
grease, wipe off any excess grease.

adjustment due to normal wear of friction sur-
faces. Check PTO electric clutch/brake adjust-
ment every 100 hours.
To adjust PTO Electric Clutch/Brake:
1. Stop engine, set parking brake and remove
ignition key.
2. Clutch has three springs and adjustment
nuts. All three must be adjusted equally.

PARKING BRAKE ADJUSTMENT
Brake adjustment is made at rear of machine
under seat.
1. Loosen rod lock nut.
2. Release transmission push valves.
3. Remove hairpin cotter and pin from clevis.
Turn clevis one complete revolution for
adjustment and reinstall pin and hairpin
cotter. Note proper position of clevis.
4. Repeat step 3 until both rear tires skid
when machine in pushed with parking
brake set.
5. Tighten brake lock nut while holding
adjustment rod. Check so that parking
brake can be engaged. If not, brake is too
tight.
6. With parking brake released, make sure
tractor rolls freely.
7. Engage transmission push valves.
If tractor creeps after brake is released, neu-
tral setting requires adjsutment. See your
Authorized TORO Wheel Horse Dealer for this
adjustment.
CLEANING AND STORAGE
After 30 days, painted surfaces may be waxed
to protect lustre of original finish. Machine should
В
Parking Brake Adj ustment
be washed regularly with a mild automotive type
detergent and water. Avoid excessive use of
water, especially around control panel, engine
and transmission. Do not pressure wash.
-16-
Exposed bare metal surfaces should be coated
with oil for a light coating of grease to prevent rust
until permanent repairs can be made. Aerosol
cans of touch up paint are available through your
Authorized Toro Wheel Horse Dealer.
When machine will not be used for an extended
period of time, following steps will help insure
minimum difficulty when unit is returned to serv-
ice:
1. Perform required maintenance steps called
for in “Maintenance Checklist”.
2. Check tires for proper inflation.
3. Wash machine and repaint all bare metal
surfaces.
4. Start machine and engage mower for ap-
proximately 1 minute to remove excess water
from belts and pulleys. Let engine run out of
gas. As gasoline grows old, it becomes less
volatile and forms harmful gum and varnish
deposits in carburetor and fuel system. DO
NOTSTORE GASOLINEFORMORE THAN
2 MONTHS.
5. If applicable, charge battery. In tempera-
tures lower than 40°F (4°C) a battery will
maintain a charge for about 60 days. In
temperatures above 40°F (40°C) water level
should be checked and battery “trickle
charged” every 30days (more often in higher
temperatures). Battery must be fully charged
to prevent freezing and internal damage in
weather below 32°F (0°C).
6. Remove key from machine.
