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,

53.
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
55.
56.
57.
58.
59.
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.
E. Reconnect spark plug wire(s) and resume
operation.
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.

SAFETY INTERLOCK SWITCHES
N CAUTION AN
Before starting engine, become familiar with
all controls. Read this Operators Manual thor-
oughly. Always check engine oil level before
starting engine.
2. Slide seat to desired position.
3. Tighten all four bolts securely.
Each machine has two interlock switches. Switches
are actuated by parking brake and seat. Parking brake
switch prevents engine from starting when parking
brake is disengaged. Seat switch will stop engine when
seat is vacated with PTO switch in “ON” position. PTO
switch must be “OFF” and parking brake engaged
before engine will start.
If machine will not start, check that parking brake is
engaged and PTO switch is in “OFF” position.
Safety interlock system must be tested periodically.
To test operation, following functions must be ob-
served. If not, immediate repairs must be performed by
an Authorized Toro Wheel Horse Dealer for your pro-
tection.
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.
SEAT ADJUSTMENT
The seat can be adjusted for optimum operator com-
fort.
1. Loosen four bolts.
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 slow position. Pull choke control ail 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 automatically.
If the engine fails to start after 30 seconds of
continuous cranking, turn the key to the Off
position and allow the starter motor to cool.
Check forthe cause of hard starting; consult the
Troubleshooting Checklist.
Once engine has started, slowly return choke control
to operate position. If engine stalls or hesitates during
operation, choke should be applied as necessary until
engine reaches normal operating temperature.
STOPPING ENGINE
To stop engine; move throttle leverto Idle position and
turn ignition key to “Off” position. If engine has been
working hardorengine is hot, allow engine to idle a short
time before turning key off. This practice will help cool
engine before stopping.
-5-
Note: In case of emergency engine may be stopped
by turning ignition key to “Off” position.
Engine is equipped with a high temperature horn
alarm. During operation if horn sounds, disengage РТО
and allow engine to cool. Check cause of engine
overheating and correct as necessary or contact your
nearest Toro Wheel Horse Dealer for service.
A 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 persons an op-
portunity to operate this machine.
THROTTLE CONTROL
Throttle control regulates speed of engine as meas-
ured in RPM (Revolutions Per Minute). This control
Should not be used to regulate the ground speed.
Engine has been designed with a special governor
that limits engine RPM. Unlike an automobile, this
governor allows engine to operate most efficiently at a
set speed and protects it from damage caused by
excessive RPM. Always operate machine with throttle
control set at full speed.
CHOKE CONTROL
Choke control activates a “butterfly” valve in carbure-
tor. 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 if
carburetor is adjusted properly.
FUEL RECOMMENDATION
Use clean, fresh, unleaded gasoline. Regular leaded
gasoline may also be used but it is not a preferred fuel.
Do not use highly leaded premium gasoline. Use of
unleaded gasoline results in less maintenance.
If regular leaded gasoline is used continually, carbon
and lead deposits should be removed from the cylinder
heads as required because of engine power loss.
Unleaded gasoline may be used safely after lead de-
posits have been removed.
IMPORTANT
Do not use gasoline de-icers. Gasoline de-
icers can cause internal damage to carburetor
and fuel pump parts. Do not use fuels contain-
ing alcohol concentrations greater than ten per-
cent. Fuel containing alcohol may cause poor
engine performance and internal engine dam-
age.
OIL SPECIFICATION
To protect your machines engine check engine oil
level before each use. Complete information concern-
ing recommended oils and how to check oil levelis given
in “Maintenance” section of this manual.
CORRECT TRANSMISSION OPERATION
TO GO FORWARD OR REVERSE
Machine is equipped with a separate transmission for
each rear wheel. Transmissions are controlled with
“Motion Control Levers” one for each wheel.
ZN CAUTION À
Always release parking brake slowly when
starting the machine in motion. Sudden starts
can be damaging to equipment and could cause
loss of operator control.
For safe operation, never move the motion
control lever too rapidly, especially on grades.
To go forward, release parking brake and push both
levers forward evenly.
Togo in reverse, release parking brake and pull back
on both levers evenly.
TO CHANGE SPEED OR DIRECTION
To change direction of machine, slowly move levers to
neutral and move levers in direction you want to go.
Further levers are moved away from neutral position,
faster machine will travel. To turn machine left or right,
slow machine down and then slow speed of wheel in
direction you want to turn.
TO STOP
To stop machine, return both levers evenly to neutral
position. Always engage parking brake, shut off engine
and remove ignition key before leaving machine.
CORRECT MACHINE USAGE
ZN CAUTION A
fore operating. These manuals give a detailed
areas of caution. Familiarize yourself thor-
oughly with equipment before attempting to
use it.
OPERATION OF MACHINE:
WITH MOWER
IMPORTANT
Keep all shields and mower discharge chutein
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 the
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
past. This will help you determine best approach to
uneven areas, to be sure wider cut does not result in
scalping high spots. In general, recommended cutting
height is 2 to 3 in. (5 to 7.6 cm).
Very tall or wet grass can be cut without difficulty by
using a little care. Set mower in its highest cutting
position and enter area slowly. If necessary, take a cut
one 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.
Read manuals provided with attachments be- | |
description of operation and point out other |
“ Mower Height Down Stop
Mower is equipped with a height down stop. Loosen
bolt and move stop up ordownto adjust. Retighten boit.
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 swinging 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.

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 sepa-
rate gasoline engine, some are “ground driven” and
some are simply towed, such as a lawn sweeper or
dump can.
In any case, all these attachments should be ap-
proached with same amount of caution given any

IMPORTANT
Do not overfill crankcase. Excess oil causes
high oil consumption and oil accumulation in
air cleaner housing.
Failure to change engine oil at recommended
intervals can lead to serious damage to engine.
This is especially true when using detergent
oils which are designed to hold impurities in
suspension; when saturation point is reached,
oil may suddenly break down to form a gelatin-
like substance which seriously impairs and can
even stop flow of oil. Increase frequency of oil
changes if machine is operated under extremely
dusty conditions.
Oil Changes
Engine oil in your machine should be changed after
first 25 hours of operation. Thereafter, oil should be
changed at 50 operating hour intervals. Oil filter should
be changed every 100 hours. If operating conditions
are extremely dusty or dirty frequency of oil changes
should be increased.
Before changing oil, start engine and allow it to warm
up. This will allow oil to flow more freely. Shut off engine
and remove key. Open oil drain. After oil has drained
completely, reinstall drain cap.
Engine Oil Dipstick/Fill and Fuel Filter

If oil filter is to be replaced, unscrew used filter and
install new filter on engine.
Remove dipstick/oil fill cap and add about 80% of
amount of oil specified in following chart. Also shown
are charts for selecting correct oil type and oil viscosity.
When using temperature - viscosity chart, select air
temperature most likely to be encountered within next
50 hours of operation.

Never overfill engine crankcase with oil. Oil
level must not exceed “F” level on dipstick.
Air Filter
Dirt induced through improperly installed, poorly serv-
iced, or inadequate air filter elements, is more often
cause of aworn 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 airfilter 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 conditions. To
protect your engine, use only manufacturer's replace-
ment filter, or replacement filters with equivalent speci-
fications.
Check following when installing a new or serviced
element:
1. Base must be securely tightened to carburetor.
Replace base if bent or cracked.
2. Gasket surfaces of element must be flat against
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 let unfiltered air into carburetor.
To prevent any dirt or other contaminates from
entering engine, always cover carburetor air
horn when air cleaner is removed.

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 on
engine. clean precleaner at 25 hour intervals, when air
cleaner is serviced. Wash precleaner in a solution of
liquid dishwashing detergent and water. Squeeze out
excess water and allow itto dry. Coat precleaner evenly

Spark Plug
Engine misfires, or generally poor operation, is often
caused by spark plugs in poor condition or with incorrect
spark plug gap setting. Check spark plugs at 200
operating hour intervals. Replace if inspection reveals
fouling or excessive deterioration.
Always clean area around spark plugs before remov-
ing them to prevent dirt form entering engine. Use a
spark plug wrench to remove and install plugs.
Check condition of plug(s). Good operating condi-
tions are indicated by a light coating of gray or tan
deposit. A dead white, blistered coating could indicate
engine overheating. A black coating could indicate an
-11-
“overrich” fuel mixture caused by a clogged air cleaner,
or improper carburetor adjustment.
Replace spark plugs that are not in good condition.
Never sandblast, wire brush, scrape or otherwise
service a spark plugi in poor condition. Best results
are obtained with a new plug.
Always check spark plug gaps before installing a new
plug or reinstalling original plug. Use a spark plug gar:
gauge to adjust electrode air gap to .025 (.64 mm) for
724-Z. Torque plugs at 15 ft. ibs. (20mm).
Carburetor Adjustment
Carburetors are adjusted at factory and should noi
have tobe reset. If however, one of following conditions
Is noted, carburetor should be readjusted immediately
as continued operation with incorrect setting canlead to
fouled spark plugs, overheating, excessive valve wear
or other problems. If black exhaust smoke is noted,
check air cleaner first - an “overrich” mixture is usually
caused by a poorly serviced, clogged air cleaner ele-
ment, not an improperly adjusted carburetor.
Carburetor Adjustment
Correct carburetor adjustment requires significant
amount of knowledge as well as special equipment,
such as a good tachometer, In addition, other adjust-
ments, such as governor settings, may also be neces-
sary after adjusting carburetor. For these reasons, it is
suggested that carburetor adjustments be performed
by an authorized dealer.
Fuel System
Fuel Strainer
A fine-mesh screen type strainer, incorporated into
fitting at bottom of each fuel tank, and aninline fuel filter,
both filter foreign matter from gasoline before it reaches
the carburetor. This strainer and fuel filter normally
require service only if fuel supply becomes severely
contaminated.
Always clean area around fuel cap before removing it
to prevent excessive amounts of 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, when cold
and damp weather conditions can cause moisture to
condense in tank.
EXHAUST SYSTEM
Make regular visible and audible inspections of ex-
haust system throughout entire life of the machine.
Locate leaks in muffler and piping while engine is
operating. Repair all leaks immediately after they are
detected for or personnel safety.

CHARGING SYSTEM
An alternator is used to charge battery. Alternator
charging system normally requires no service other
then periodically checking that all exposed wiring and
electrical connections on machine are clean, tight and
in good condition.
IMPORTANT
Never run engine if battery is removed, or if
battery is not connected to charging system.
Serious damage to charging system compo-
nents may result.
-12-
IMPORTANT
Proper polarity is critical with an alternator
equipped charging system. Always disconnect
battery ground cable (negative) before working
on any part of electrical system. Verify all
components are connected correctly before re-
connecting ground cable (negative) or damage
to alternator system components will result.
ELECTRICAL SYSTEM
Fuses
Three fuses protect the machines electrical system
and components from excessive current and short
circuits.
Ln оли
A 25 amp fuse protects the electric start circuit. A 15
amp fuse protects the hourmeter and PTO electric
clutch circuit. A 30 amp fuse protects the machine's
charging system. Fuses are contained in fuse holder
clipped to the frame under seat.
A “blown” fuse is an indication of short circuits of
current overloads. Refer to the wiring diagram in the
back of this manual and become familiar with the
machine's electrical system before attempting to trou-
bleshoot. Check all wiring for shorts or other damage
before replacing any fuses.
Battery

A CAUTIONA\
Battery electrolyte solution is poisonous and
can be injurious to eyes, skin and clothing. In
event of an accident, flush atfected area imme-
diately with a solution of one part baking soda
to four parts water. Notify physician immedi-
ately. If baking soda is not immediately avail-
able, flush affected area with water. Notify
physician immediately.
Maintain electrolyte level above plates in each cell by
adding distilled water as necessary. Best time to add
water is just prior to operating machine so water will mix
with solution. Do not overfill battery. Electrolyte solu-
tion 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 removed 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 terminal should be removed by applying a
solution of one part baking soda to four parts water. A
light coating of grease or petroleum jelly may be applied
to all exposed terminal surfaces to prevent corrosion.
NOTE
At temperatures below 32°F (0°C), full charge
state must be maintained to prevent cell electro-
lyte from freezing and causing permanent bat-
tery damage.
TAPPET ADJUSTMENT
Valve clearance must be checked at first 50 hrs.and
thereafter every 200 hrs. of operation. Consult your
Toro Wheel Horse dealer for service.
HYDROSTATIC TRANSMISSION
Each rear wheel is controlled by a separate trans-
mssion.
Lubricant levels should be checked before each use.

DRIVE CHAINS
Review all sections on chain operation and adjust-
ment before servicing.
Following instructions are for one side, repeat steps
for opposite side.
1. Rear wheels are driven by primary and secondary
chains. Check these chains periodically. Lubricate
with light chain oil as necessary.
2. Primary chain should not require periodic adjust-
ment.
3. Replacement of both chains and sprockets is
recommended when either exhibits excessive wear.
4. Check secondary chain deflection periodically and
adjust chain tensioning idler as necessary to maintain
proper chain deflection.
PRIMARY CHAIN ADJUSTMENT
(Service Only)
1. if not already done, close LH and RH fuel shutoff
valves, remove fuel tank and securely plug fuel line.
2. To adjust primary chain, loosen two bolts on
outside and inside pillow block bearings. Add or
remove equal number of shims at pillow block bearing
mounting locations.

4. Always maintain jackshaft alignment so jackshaft
sprocket is in line with hydro output sprocket. Also
inner secondary drive sprocket must be in-line with
drive hub on axle.
-16-
5. Measure chain deflection midway between sprock-
ets. Secondary chain should have deflection range
1/4-1/2 inches.
6. If service is necessary to adjoining pillow block
bearings, jackshaft or transmission adjustment to both
chains may be necessary.
SECONDARY CHAIN ADJUSTMENT
1. With idler bolts loose, slide idler sprocket
bracket to obtain 1/4-1/2 inch of chain deflection.
2. Maintain secondary chain deflection of 1/4-1/2
inch while tightening idler bolts.
PARKING BRAKE ADJUSTMENT
Eachrearwheel has a separate parking brake. Adjust
both sides at same interval.
To adjust parking brake:
1. Loosen yoke jam nut and tighten or loosen yoke so
that parking brake may be engaged without excessive
effort and when engaged, prevents units movement.
2. Adjust opposite side using same procedure.
CLEANING AND STORAGE
After 30 days, painted surfaces may be waxed to
protect the lustre of the original finish. Machine should
be washed regularly with a mild automotive type deter-
gent and water. Exposed bare metal surfaces should
be coated with oil or a light coating of grease to prevent
rust untilpermanent repairs canbe made. Aerosolcans
of touch up paint are available through your Authorized
Dealer.
When the machine will not be used for an extended
period of time, following steps will help insure minimum
difficulty when unit is returned to service:
1. Perform required maintenance steps called for
inthe “Maintenance Checklist”.
2. Check tires for proper inflation.
3. Wash machine and repaint all bare metal surfaces.
4. Start machine and engage mower for approxi-
mately 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
NOT STORE GASOLINE FOR MORE THAN 2
MONTHS.
5. If applicable, charge battery. In temperatures
lower than 40°F (40°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 30 days (more often in higher tempera-
tures). Battery must be fully charged to prevent
freezing and internal damage in weather below 32°F
(0°C).
6. Remove key from machine.
