Because of a built-in safety interlock system, your
new Wheel Horse will not start until the clutch pedal
is de pressed and the PTO (power take-off) is dis­
engaged.

When starting the engine during cold weather,
engage the parking broke. When the parking brake

&CAUTICN&
The engine MUST be operating at a minimum
of �"" throttle whenever the trador is in use.
Using the tractor while the engine is operating
at less than % throttle may result in extensive
damage to the automatic transmission.
Always place the transmmion gear mift 'ever
in the neutral position before attempting to
staft the engine.
CHOKE CONTROL
ELECTRIC START MODELS
w
The choke control activates a IIbutterfly" valve ;n
the carburetor. This valve limits the amoynf of row
oir available to the carburetor. If the choke is "OPEN"
the carburetor has an unrestricted flow of raw air.
If the choke is "CLOSED", the amount of raw air
available is limited. thus cau�in9 the intoke of the
engine to draw a higher fuel-fa·air mixture from the
carburetor.
w
w
Turn the ignition key clockwi!te until the storter
engages. When the engine !ttarts, release the key.
The switch is spring loaded and will return to the
run position automatically.
If the engine fail, to start after 30 seconds
of continuous cranking, tUrn the key to the
"OfF" position and allow the starter motor to
cool. Check for cause of hard starting, consult
"Troubleshooting Guide" found on page 18.
Choking the engine is required when the engine
is storted cold. Warm engines may not need choking.

STOPPING THE ENGINE
&CAUTICN&
Note:
In case of emergency. the engine may be
stopped by turning the ignition key to the nOFF"
position.
OIL SPECIFICAnONS
To protect your new Wheel Horse, check the engine
oil level before ea c h use. For maximum protection
under all operating conditions use API Service ClassiM
ficatioll "SC" oil. Oil carrying the former API Service

ate this machine.
CORRECT AUTOMATIC
TRANSMISSION OPERATION
The engine in your new Wheel Horse has been
designed with a special governor that limits tl1e en�
gine RPM. Unlike an automobile, tl1i5 governor allows
1he engine to operate most effiCiently at a �ef speed,
and protects it from damage caused by excessive RPM.
Always run the engine with throttle control set at
� to full speed.
- 5-
om
The throttle control regulates the speed of the
engine as measured in RPM (Revolutions Per Min u te).
This control should not be used '0 regulate the ground
speed of the tractor.
.c
THROnLE CONTROL
During cold weather, start the engine with the
parking brake engaged. nis releases the trans..
mission from the engine and allows the engine
to turn freely. Run the engine at full throttle
for two minutes to allow engine to warm-up.
Depress the Broke/Return to Neutral Pedal ancl
disengage the parking brake. For temperatures
between O°F and 30°F allow .he transmiSlion to
run in neutral for 5 minutes before attempting
to set the unit into motion. For temperatures be.
low O°F allow the transmission to run in neutral
for 10 minutes before attempting to set the unit
in motion. Failure to do so may result in exten_
sive internal transmission damage.
TO STOP
TO GO FORWARD
Stopping the trodor from either forward or reverse
direction can be achieved by one of two methods:
.&. CAUTION .&.
1.
Before the trodor will move either forward
w
or backward, the parking brake must be dis­
engaged. ALWAYS depress the Brake-Return 10
Neutral Pedal while disengaging the Parking
Brake.
.
2.
w
w
The motion of your tractor is controlled by a
single "Motion Control Lever", To go forward, simply
push .l"Ie lever forward. The farther forward the lever
Is pushed, the faster the troctor will go.
.&. CAUTION .&.
.M
for sofe operation, neve, move the Motion
Control Lever too rapidly I especiaUy on grades.
yW
By adjusting the Motion Control lever, the forward
speed of the troctor can be regulated without adjust .
ing the engine throttle control. For heavy pulling.
moving the control lever toward neutrol reduces
troctor ground speed and increases pu lling power
much the some as shifting 10 a lower gear with 0
mechanical transmission.
Activating the Broke (Return to Neutral) pedal auto·
matically returns the "Mofion Control Lever" 10 its
neutral position. The Brake (Return to Neutral) pedal
will hold the Motion Control Lever in the Neutral
Position. The pedal must be released before the Mo·
tion Control Lever can be moved either forward or
back.
The tractor is stopped by a "dynamic braking"
action inside the hydrostatic transmiuion. Any time
the Motion Control Lever is returned to the neutral
position the tractor should come to a s top. If the
tractor "creeps" on a level surface with the Motion
Control Lever in Neutral, consult the "Maintaining
Your TroctorU section of this manual, and follow the
instructions described under "Transmission· Neutral
Adjustment".
When operating your tractor on a slope you
can initially stop the 'rador by depressing the
HBrake�·. To preven' the tractor from rolling,
release the brake pedal and move the motion
control lever in tho 0ppoli'e direction of the roll.
PUSH VALVE
To reverse: the motion of t�c tractor, return the
motion control lever to the neutrol position, and pull
the lever bock. The further bock the lever is the
faster the troctor will go in reverse.
For safe operati on, never move the Motion

Snow removal will vary greatly with the condition
of each snowfall. lighl fluffy snow will be cleared
with ease. Heovy wet snow will be more difficult. It

Caution should be exercised whenever the snow
thrower is engaged. The auger is capable of picking
up sticks, stones and other foreign objects and ex­
pelling them with great velocity. Always aim the dis­
charge chute awoy from persons or objects sublcd to
harm.
Plows and disc require maximum trodor efficiency,

weights will add to the steering control of the tractor.
The Wheel Horse clevis hitch (deoler installed op·

the harrow attaches to the drowbar hitch.
Caution should also be exercised if the chute should
become clogged. Always shut off troctor before deor·
ing the chute or making any type of adiustments.
There are two methods of preparing a seed bed
for planting.
Use a tiller, which wiU prepare the soil in one
operotlon.
e
he
1.
Tire chains and wneel weights are recommended
for use with the snow thrower.
2. Use
plow to turn the ground, a disc to break
up large clumps, and a harrow to pulverize and
smooth the soil.
WITH A DOZER BLADE AND GRADER BLADES
0
Plows ore classified by the width of the furrow they
will turn. Generally, plows are set to cut 6" to 8" deep.
lH
Although the front end dozer blade is generally
used for snow rem.,val. it con also be used for moving
dirt. sand or gravel. Care should be taken and a slow
ground speed should be maintained whenever the
blade is used. Impact with a solid obiect may result
in iniury to the operator and/or damage to the blades.
A disc is used Immediately ofter plowing. The disc
will break the large clumps of soil.
After discing, most generally. 0 spiked tooth harrow
is dragged over the soil. The spiked tooth harrow
helps pulverize the soil and levels 'he seed bed. The
soli should now be ready for planting.
or
Grader Blades are genero!ly preferred for leveling
sand, dirt or gravel. The operation of these blades is
s;milar to that of a dozer blade. The rear mount
blade requires a Wheel Horse 'slot or clevis hitch (deal·
ar installed option).
se
The cultivator is used during the growing season to
help remove unwanted weeds, and to help aerate
plant roots. Generally the width of the cultivator is
token into consideration before planting the seed
bed to Insure the cultivator fitting between the rows
without damaging the crop roots.
.c
When using any of these attachments with the troc�
for, front wheel weights should be used to increase
front wheel traction. Reor wheel weights and tire
choins may also be needed to increase rear wheel
traction.
WITH A FRONT END LOADER
WITH A TILLER
The Wheel Horse 36" tiller does on excellent job
of preparing gardens for planting.
Caution should be exercised when tilling virgin
ground or clay as the tiller may have 0 tendency to
push the tractor. This con be correded by raising
the tiller with the ottochment lift so the tiller pene­
rates only the very top of the soil. The tiller can be
relowered to its full depth on following posses.

Slightly pitted points can be dressed down with
a point file. This should be done ONLY as a
