battery is being charged (+) or discharged (-l.
8. Speed Control Lever
Push
T-handle ahead to drive the tractor for-
ward. Pull the handle back for reverse. Move
handle to neutral (center) position to stop.
Brake pedal on the left side of Ihe tractor
also moves the lever to neutral position for
dynamic braking.
The control lever also varies ground speed and
pulling power of the tractor independent of
engine speed. To increase speed, move handle
away from neutral. Increase pulling power by
moving handle toward neutral.
9. Hydraulic Lift Lever
Move the lever forward to lift an attachment.
Release lever to hold attachment in position.
Pull lever rearward 10 lower attachment. Pull
lever rearward past delent to lock lever in
float position. Float position permits the attach-
ment to folbw ground contours independent
of tractor motion.
10. Parking Brake Lever
Pull handle to engage brake, push down to
disengage. Brake should always be set when
dismounting or when starting engine. When
the brake is set, the drive belt is automatically
released. Caution: Do not set parking brake
while tractor is in motion as this may result
in damage to the transmission. Always depress
brake pedal (on left side) before releasing
parking brake.
STARTING THE ENGINE
1. Before starting the engine, fill the gas tank
with a good grade of regular gasoline and
open the fuel shutoff valve at the bottom of
the tank.
2. Check the oil level in the engine crankcase
with the dipstick. See Fig. II. Add oil as neces-
FIGURE 11
50ry to bring oil to proper level. Do not over-
fill.
3. Push broke pedal (See Fig. II) to make sure
transmission is in neutral. Also engage parking
broke.
4. Pull throttle knob X way out and turn to the
right to lock in position.
S. Pull choke knob all the way out to choke
engine. When restarting a warm engine, chok-
ing may not be necessary.
6. Make sure electromagnetic P.T.O.clutch switch
is in the disengaged position. Turn ignition
key all the way to the right to operale the
starter.
7. When engine starts, push the choke knob in
and regulate engine speed with the throttle
control. Turn throttle control to the left to
unlock and change its position.
8. To set Iractor in motion, release the parking
brake and move the speed control lever
either forward or to the rear, depending on
the direction you wish to go.
STOPPING THE ENGINE
1. Disengage the electromagnetic P.T.O. clutch.
2. lower any attachment controlled by the
hydraulic lift.
3. Unlock and push the throttle control to idle
position. If the tractor has been working hard,
allow the engine to idle a short time to
normalize temperatures before shutting it off.
4. Engage parking broke.
5. Turn ignition key to the left to "off" position.
Remove key from the ignition switch.
HYDROSTATIC TRANSMISSION
Tractor speed, direction and braking are con-
trolled by the speed control lever located on the
center panel.
• To go forward, push the control lever forward.
• To go backward, pull the control lever back.
• To stop, put control lever in neutral position.
• You may also stop the tractor at any time by
depressing the brake pedal on the left side.
Tractor speed is affected instantly by movement of
the control lever. For safest operation, the control
lever should not be moved too rapidly especially on
grades.
Most power-driven attachments, such as rotary
mowers, are designed to operate at full engine
speed. The Hydrostatic transmission permits you 10
adjust tractor ground speed to suit operating con-
ditions, while continuing to drive power-driven at-
tachments at full engine speed for maximum
efficiency.
For
heavy pulling, moving the control lever toward
neutral reduces tractor ground speed and increases
pulling power much the some as shifting to a lower
gear with a manual transmission, except that engine
speed is not affected.
Towing Instructions:
This tractor should never be towed or pushed
without first opening the towing valve. The towing
valve is located under the seat on the top surface
of the pump. To push or tow, follow directions on
towing decal. (See Fig. III). Caution: Do not tow for
long distances or over a speed of seven (7) miles per
hour.

FIGURE III
ELECTROMAGNETIC P.T.O. CLUTCH
The electromagnetic clutch is used to drive the
power-driven attachments. This is a sealed unit and
does not need lubricating. To engage the clutch,
operate the clutch switch. (See Fig. I). Prolonged ex·
posure to water and freezing temperature could
couse the clutch to become frozen. Do not attempt
to use the clutch if this condition exists.
Note: Always disengage the clutch before stopping
the engine. Although the clutch automatically dis-
engages when the ignition switch is turned off, the
engine cannot be restarted until the clutch switch is
in the disengaged position.
HYDRAULIC LIFT
To lift an attachment, move the lift lever forward.
To lower, move lever to Ihe rear. The neutral posi-
tion will hold on attachment at any position from
full up to full down. A float position is also provided.
Move the lift lever fully to the rear post detent
resistance. This hydraulic "float" permits on atlach-
ment to follow ground contours independent of the
tractor's motion. The lever will remain in float posi-
tion until changed manually. All attachments should
be lowered after use. BRAKES
The broke pedal on the left side of the Iractor
provides dynamic braking 10 both rear wheels
through the hydrostatic transmission.
PARKING BRAKE
The parking broke lever is located on the right
side of the center control panel. (See fig I.) To set
the parking broke pull on the handle. Broke should
always be set when dismounting from traclor, espe-
cially on a grode, otherwise the tractor may creep.
When brake is set, th e drive belt is automatically
released. Caution: Do not set parking broke while
tractor is in motion as this may result in damage
to the transmission. Always depress broke pedal
before releasi ng parking broke.
LUBRICATION AND MAINTENANCE
BATTERY
With proper core this battery should give the long
service life built into it.
A
battery which does not function properly is not
necessarily worn out or defective. It may only need a
good recharge. Therefore, if battery trouble is sus-
pected, a full recharge and test by a competent
battery man is recommended.
Care In Service
A hydrometer test of the battery solution should
be mode monthly. If the specific gravily tests 1.225
or less, the battery should be removed and thoroughly
recharged. At the same time the solution level should
be examined and distilled water added when neces-
sary to retain the level over the plates. When neces-
sary to odd distilled water, do it just prior 10
recharging so that the added water mixes with the
solution.
When recharging is necessary and user does not
have his own charging equipment, he should request
service station to slow charge the battery at a rate of
2 to 3 amperes. Fast charging is not recommended.
Any collection of grease or any other substance
should be removed from the top of the battery and
the top kept dry and clean 01 all times. The battery
should be kept snug in its cradle and not permitted
to ge t loose. If removed for charging, it should be
fastened snugly enough to prevent any movement
when in use. Vent cops should be kept tight and the
small vent holes in top or side of cap be kept open
at all times to permit escape of gas formed in the
battery.
Core should be exercised not to over fill the battery
at any lime and to always retain solution above
the plates.
Winter Care
If battery will not be used during the winter
months it should be removed and stored in a cool.
dry place. Any collection of grease or other substance
should be removed from the top of the battery.
The battery must be recharged monthly or when-
ever the hydrometer reads less than 1.22S.
Before reinstalling the battery in the spring, it
should always be given a thorough recharge.
BELTS
Drive belt tension is automatically maintained by
a spring-loaded idler pulley on the parking brake
linkage. When th e parking broke is released, the
belt is properly engaged with the engine and trans·
mission pulleys.
Belt guides are mode as part of Ihe belt guard.
They are pre-set to proper clearance at the factory
and require no further adjustment.
Drive Belt Replacement:
- 8 -
1. Remove the belt guard from the tractor.
2. Remove th e wire, hairpin cotler and clevis
pin from the electromagnetic clutch bracket.
(See Fig. IV).
FIGURE IV

3. Engage the parking brake to release the ten-
sion on the drive belt.
4. Remove old belt and install new belt in its
place.
5. Release parking brake to apply tension to the
new belt. (See Fig. IV).
6. Reinstall belt guard making certain the upper
and lower belt guides run along the under
edge of the belt.
7. Swing clutch arm into position and insert
clevis pin through holes in the bracket and
clutch arm . Install hairpin cotter and the wire
to the clutch.
Attachment Belts:
Install attachment belts on the electromagnetic
P.T . O. clutch by fol lowing steps (2) and (7) above .
When replacing belts, it is advisable to purchase
them from Wheel Horse dealer . These belts are spe-
cifically designed for each tractor and attachmen t.
CHASSIS LUBRICATION
At least every 25 hours, lubricate the five pressure
fittings with a grease gun and a good quality multi-
purpose gun grease.
Fitting Locations,
• Top af steering column (See Fig. I).
• Steering sector gear (See Fig. V).
• Center of front axle
• Both front wheel spindles.
Use a light machine oil to lubricate other wear
points and linkage joints.
At
least once per year, remove, clean and repack
front wheel bearings with wheel bearing grease.

clean in any liquid or with compressed air . Replace
element after 100 hours . This can be extended up
to 200 hours if good, clean operating conditions
prevail.
Not e: The engine manufacturer's maintenance
schedule and procedures are giuen in the engine
manual which came with your tractor. It is advisable
to study these recommendations and fo ll ow them to
assure long engine life and trouble-free operation.
FUEL SYST EM
Use clean, fresh, REGU L AR GRADE gasoline. Do
not mix oil with fuel. Take the time to clean the
area surrounding the fuel tank filler neck to prevent
entrance of dirt and clippings into the tank.
Cau tion: Never fil l fuel tank with engine running.
Use care not to spill fuel on engine or heat shield,
especially when hot.
Fuel Filt er:
The in-line fuel filter (Fig. II) should be cleaned
after the first 25 hours operation and at 25 hour
intervals thereafter. To clean the filter, remove the
center screw, separate the two halves, rinse in clean
solvent, and reassemble .
HEAD AND TAIL LIGHTS
The head and tail light circuit is protected by the
AGe 20 amp. accessory fuse in the line from the
ignition switch. It is replaced by separating the cap-
sule to remove the spent fuse and insert the new on e.
(See Fig . II).
T he head and tail lamp lenses are removable to
provide access ta the bulbs . The head lamp lens is
secured by four screws . The tail lamp lenses snap
in place. A lifting slot is provided at the bottom of
the lens to facilitate removal.
HYDRAU LI C LIFT
The float detent resistance is adjustable. This is
done by turning the socket head ball spring screw
(Fig. VI) clockwise to increase, or counter-clockwise to
decrease the detent resistance . The detent is cor rectly
adjusted when the resis t ance is just great en ough to
hold the valve in float position.

TR ANSMISSION
Oil Filter:
Replace the oil filter after the first 10 hou rs
operation. T hereafter, replace it after every 100 hours
operation or once per year whichever occurs first.
O il :
Check oil level before every use. Replenish as
necessary to maintain proper level as indicated on
dipstick attached to filler pipe vent plug . USE ON LY
TYPE "A" AUTOMATIC TRANSMISSION FLU I D.
Drain and refill transmission once eac h year or
after every 100 hours operation whichever occurs
first. The
transmission is drained by removing the
plug at the bottom of the transaxle. Four quarts of
Type "A" Automatic Transmissio n Fluid a re required.
Use care to prevent dirt, clippings or other foreign
material from entering the transmission when cha n g-
ing oil or replacing the oil filter.
Ne utral Adjustment:
If tractor should creep while in neutral position,
this can be corrected. To check for creep, place tr a ctor
on level surface with engine run n ing, and depr ess
broke pedal. Creep on slopes is normal and can n ot
be entirely eliminated.
To make neu t ral adjustment (See Fig VII):
1. Block rear wheels off grou n d.
2. Remove instruction plate, (located in front of
the seat) by removing the screws which ho ld it.
3. loosen set screw in arm with allen wre nch
( See fig . VII).
4. Depress brake pe d al.
S. With tractor engine running and park i ng broke
disengaged, insert short screwdr i ver through
hole in nylon cam and ro ta te t he eccentric com
pin until rear wheels stop. Now retighten set
screw in arm and replace plate.
6. Not e: T he lobe on t he eccentric pin must be

Co ntrol le ver Friction Adju st me nt :
The
control lever is friction loaded so it will hold
at any desi r ed speed . The tension has bee n adjusted
at the factory and should need little or no attention.
If the lever does not s tay where it is set during
operotion, the friction may be increased by releasing
the locknut and tightening the collar·friction adjust .
ment. ( See Fig. VIII ). The proper amount of friction is
obtained when approximately eight pounds of f orce
at the ha ndle grip moves the control lever. Be sure
to tighten the locknut after proper tension has been
reached. The friction collar is self lubricating and
does not require lubrication.
