Congratulations on your purchase of this fine riding tractor.
We, the Manufacturer, know you bought this machine to
your lawn and garden work easier. You bought the right
machine to do it. So that you can get the very most from
your purchase, we would consider it a personal favor if you
would take time to study this manual before using your
tractor and its attachments. It will increase the chance of
adding you to our long list of satisfied customers. Also,
before allowing others to operate your tractor, be sure they
read and understand the safety precautions and operation
section of this manual.
For your own safety and that of your family and friends,
periodically review the safety tips found on the inside front
cover and page one of this manual. Before we learn how to
operate the tractor, let's take a look at some of its exciting
features.
EASY STEERING — 3.3 to 1 ratio gear and sector steering
of true geometric design. The front wheels follow different
arcs when turning, giving improved steering and minimizing
wheel marks on soft lawns. The short turning radius (22
inches inside rear wheel) gives excellent maneuverability¬
turning time.
EASY TO REACH HAND OPERATED CONTROLS. Gear¬
shift, choke-o-matic, ignition switch, and ammeter are con¬
veniently located at the instrument panel. The power take¬
off clutch lever and implement lift lever are lo'cated for
natural, easy operation. Easy to reach parking brake is
simple to use and dependable.
SMOOTH OPERATING COMBINED CLUTCH AND
BRAKE PEDAL. Start and stop with easy rocker action
and no wheel skid. Improved clutch converts any transmis¬
sion speed from zero to maximum without shifting for
inching or turning.
QUICK SWITCHING ATTACHMENTS. Custom engineering
implements are designed to be simple to attach and remove
as well as operate. The broadest variety of front, center and
rear mounted implements offered.
DEPENDABLE BRIGGS & STRATTON EIGHT HORSE¬
POWER ENGINE with twelve volt electric starter system,
including a 32 amp. hr. automotive type battery. Vertical
driveshaft provides maximum power to attachments, simple
protected drive system, and low center of gravity.
RUGGED CHANNEL FRAME CONSTRUCTION FOR
DURABILITY AND LONG LIFE; electrically welded,
heavy gauge steel. Short wheelbase, large low pressure tires.
New bead lock rims keep tires sealed at low pressures for a
very soft ride.
DEPENDABLE, ALL GEAR TRANSMISSION. Fully en¬
closed, sealed and lubricated. Limited slip differential re¬
duces wheel slippage on slippery or sloping surfaces, yet
allows each wheel to rotate at required speed while turning.

OPERATION
CONTROLS AND HOW TO USE THEM
Picture yourself seated on your tractor. Before starting the
engine, let's learn how to use each of these safe, easy to
reach controls. {The numbers on the Figures 1 & 2 cor¬
respond to the paragraph numbers below.)
1. Ignition Switch: When turned clockwise to the first posi¬
tion the ignition is turned on. Turn past this position to
actuate the starter. (If the starter does not actuate, be sure
the shift lever is in neutral and the power take-off disen¬
gaged.) Release the key as soon as the engine starts. Return
the key to the vertical position to stop the engine.
2. Engine Speed and Choke Control Lever: The engine
speed and choke control should be moved all the way up
for the choke position. Placing the control lever up to the
fast position increases the engine speed and down to the
slow position decreases the engine speed.
3. Ammeter: The dial pointer will move right to the
"Charging" position when energy is being drawn from the
battery. The pointer will normally fluctuate to either side
of the dial center.
Figure 1
4. Light Switch: (Optional) Place the toggle switch in the
"Up" position to turn on lights. Power for lights is taken
from the engine dual alternator system and not the battery
therefore the light intensity will depend on the engine RPM.
The ignition switch must be in the on position for the lights
5. Fuel Gauge and Filler Cap: The gauge measures the level
of fuel in the tank. Turn the cap counter-clockwise to re¬
move for refueling.
6. Clutch and Brake Pedal: Depressing the pedal will first
disengage the tractor drive clutch. As you continue to de¬
press the pedal the brake will be applied to stop the tractor.
7. Gear Shift Lever: The gear shift lever is used to select
the desired transmission gear speed and direction. There are
three forward and one reverse positions.
First 1.07 MPH
Second 2.45 MPH
Third 3.81 MPH
Reverse 3.81 MPH
The diagram printed on the panel shows the location of
each position. To shift the transmission into first or reverse
from the neutral position, it is necessary to pull UP on the
shift lever to overcdme the force of the shift fork spring.
After you feel the lever pass the spring, push the shift lever
to the left or right and place the transrtiission into reverse or
first gear as you desire. To shift into second or third, push
DOWN on the shift lever from neutral until you fee! it over¬
come the spring, then push it to the left or right until it is
in second or third gear. Do not attempt to move the shift
lever unless the foot pedal (item 7) is depressed and the
tractor is stopped.
8. Parking Brake Lock: To lock the parking brake, grasp
the handle and pull it upward and back until it rests against
the seat deck. To release, pull the top portion away from
the seat deck and push it down. NOTE: Depress foot
pedal before engaging or releasing.
9. Power Take-Off Clutch: The power take-off clutch con¬
trols power to attachments such as a mower or snow throw¬
er which are driven by the engine pulley. The clutch operates
by engaging or disengaging the front pulleys with the im¬
plement drive belt to increase or decrease tension. To en-
3

gage the drive, slowly push the lever forward and down alt
the way to the engaged position. To disengage the power
take-off drive, pull the lever completely to the rear. The
engine should be running at three fourths to full throttle
when the power take-off is engaged to absorb the initial
effect of the added load. Tractor ground speed can be regu¬
lated with the transmission throttle. (The power take-off
must be disengaged for the starter to operate.)
10. Lift Lever: The lift lever is used for lifting the rotary
mower or other implements out of the operating position
so they can be transported. The implement is connected to
the lift lever either with a lift chain or a lift link to the
front or rear of the tractor. The thumb button on top of the
handle is pressed to disengage the latch from the quadrant
so the lever can be moved forward or rearward as required
and locked in position. See the attachment book for speci¬
fics on how the /ever is to be used on your particular im¬
plements. All attachments pull back on lift lever to raise and
release forward to lower. Attachment when lowered operate
in a float position. Lift lever will lock only in the raised
position.
BEFORE STARTING
Though your dealer may have performed the before starting
check listed below, we suggest you personally check each
one so that you will become familiar with them and also to
insure that your tractor is ready to go the first time you use
it.
1. Tire Inflation: The tractor is shipped with all tires in¬
flated to 25 P.S.S. Before operating, reduce pressure in all
tires. The front tires 12 to 15 P.S.l. and rear 6 to 8 P.S.I.
2. Engine Oil: Be sure the oil in the engine crankcase is at
the proper level. See your Briggs and Stratton manual and
page 10 (Figure 3) of this manual.
3. Transmission Oil: Check the transmission to insure it is
filled with oil to the proper level. See page 11 of this man¬
ual for type and weight of oil to use. (Figure 4)
4. Fuel Supply: Check the fuel supply. Fill tank complete¬
ly with clean, fresh, leaded or non-leaded "Regular" grade
automotive gasoline. (Do not mix oil with gasoline). Store
gasoline in small quantities as prolonged storage produces
gum. See page 12.tern 6 of this manual. (Figure 5)
Figure 4
CAUTION
Gasoline is highly inflammable. Avoid overfilling and
wipe up any spilled fuel. Allow no open flame, smok¬
ing or matches near the area when refueling.
5. Battery: Be sure the battery is filled to the proper level
with electrolyte and the vent holes on each cap are open.
See page 11.
6. Lubrication: Lubricate all grease fittings and oil lubrica¬
tion points as shown in the "Maintenance" section of this
manual on page 10.
7. Attachments: Read and become familiar with the AT¬
TACHMENT MANUAL which refers to attachments you
will be using with your tractor. IMPORTANT: If you are
using a rotary mower with your tractor, the front to rear
height adjustment must be checked. See the Rotary Mower
Attachment Manual.

STARTING THE ENGINE
STOPPING THE ENGINE
1. Insure that the power take-off is disengaged by moving
the lever to the rear and down. The engine will not start
unless the power take-off is disengaged. (Figure 6)
2. Place the transmission shift lever in the neutral position.
The engine will not start unless the shift lever is in neutral.
(See Figure 6)
3. D epress the clutch-brake pedal all the way and hold it
down. (See Figure 7)
Figure 7
4. Move engine speed and choke control lever up to the
choke position.
5. Turn the ignition key clockwise (see Figure 8) and hold
until the engine starts, then release. Move the engine speed
and choke control lever down to about 1/3 open.
6. Before applying a load, allow the engine to warm up for
about a minute, then move the engine speed and choke
control lever to fast or slow as needed for the operation.
1. Move the engine speed and choke control lever to the
slow position and allow the engine to idle for about a min¬
ute if the tractor has been operating under full load, to
gradually reduce engine temperature. Stopping a hot engine
too suddenly can cause damage to engine parts.
2. Turn the ignition key counter clockwise to the vertical
position and remove the key to prevent unauthorized use of
the tractor.
TRAVEL SPEED SELECTION
Tractor ground speed can be determined by placing the
transmission in any one of three forward speeds or reverse,
by adjusting the engine speed or by inching (slipping) the
clutch. When moving the tractor from place to place, be
sure any attachments are in the raised (travel) position and
the power take-off disengaged. You may find it appropriate
to use many combinations of transmission gear and engine
speed selections when transporting the tractor. The follow¬
ing guidelines are given:
Use First Gear: When traveling over rough or uneven
ground or on hilly terrain.
Use Second Gear: On slight slopes where the ground is
fairly level and even.
Use Third Gear: When traveling a distance on level ground
or pavement which is smooth and even.
Place the engine speed and choke control lever one third to
one half open when beginning travel. After starting the trac¬
tor in motion, adjust the engine speed for the desired rate
of travel. See the attachments book for recommended
travel speed when using attachments.
SHIFTING
Always depress the clutch-brake pedal and bring the tractor
to a complete stop before attempting to shift gears. To shift
the transmission into first or reverse from the neutral posi¬
tion it is necessary to pull UP on the shift lever to overcome
the force of the shift fork spring. After you feel the lever
pass the spring, push the shift lever to the left or right and
place the transmission into reverse or first gear as you desire.
To shift into second or third, push DOWN on the shift lever
until you feel it overcome the spring, then push it to the
left or right until it is placed into second or third gear. If the
gears do not engage easily, it may be helpful to let the
clutch out for an instant and then depress it again to rotate
the gears slightly.
5

STOPPING
1. Slowly depress the clutch-brake pedal until the tractor
stops.
2. Place the tractor in neutral and set the parking brake.
3. Disengage the power take-off clutch and lower any at¬
tachments to the ground.
4. If the engine has been running under full load, allow the
engine to idle about a minute before turning the ignition
key counterclockwise to the OFF position.
5. Remove the key to prevent unauthorized use of the trac¬
tor.
TROUBLESHOOTING
For instruction to overcome the following problems see
Adjustments", "Maintenance" and "Service" sections of
this book.
IF THE ENGINE FAILS TO TURN OVER - check the
following:
1. The shift lever must be in Neutral. Move the lever around
to be sure the safety switch is contacted.
2. The power take-off must be disengaged.
3- The battery cable clamps must be clean and tight.
4. The fuse must be in working condition and fuse connec¬
tion clean and tight.
5. The battery may not be charged.
IF THE ENGINE TURNS, BUT WILL NOT START, check
the following:
1. Wiring connections at the ignition switch and starter
motor must be clean and tight.
2. The combined throttle and choke control lever must be
at choke.
3. The spark plug cable must be tightly connected.
4. The fuel tank must have a good regular gasoline in it.
IF BELT SLIPPAGE OCCURS, check the following:
1. Belts may be stretched or excessively worn.
2. Pulleys may be greasy or oily.
3. Insufficient belt tension due to a broken or worn ten¬
sion spring or improper adjustment.
IF A BELT BREAKS, check the following:
1. Look for sharp edges or rough spots on the pulleys.
2. Pulleys may be misaligned.
3. Belt tension may be too tight.
4. Pulley may be binding.
IF HANDLING IS DIFFICULT, check the following:
1. Controls or drive systems may be out of adjustment.
2. Tires may be under-inflated, or not of equal pressure.
Inflate tires to REAR 6-8 P.S.I., FRONT 12-15 P.S.I.
3. Wheels spinning on slopes. Wet grass is very slippery —
try to work in the late afternoon after it has dried. Wheel
weights may be added to provide additional traction. See
Accessories section of this manual.

ADJUSTMENTS
Clutch and Brake Rod:
The correct adjustment of the clutch and brake pedal link¬
age is vital to smooth machine motion and braking. These
adjustments also determine the effectiveness of the anti-
rollback feature. You may wish to raise the tractor to the
vertical position. Be sure to drain fuel if necessary, and
remove battery before tilting the tractor. Make the adjust¬
ments as follows:
- <5'9
Depress the foot pedal and check the contact of the
brake band with the brake drum. The band must conform
fully to the curvature of the drum. If it does not, loosen the
bolt as shown and align the band with the drum. Tighten
the bolt. (See Figure 9)
2. With the foot pedal released (up), secure the brake rod
set collar against the tapered coil spring. Be sure to position
the collar as shown in Figure 10 so that the spring is NOT
compressed. Depress the foot pedal all the way down, ft
should stop two and one-half inches from the foot rest edge
as shown in Figure 11. Re-adjust the set collar if necessary
to obtain the two and one-half inch distance.
Figure 12
3. With the foot pedal released (up so the clutch idler pul¬
ley is pressed firmly against the belt (Figure 12), the dis¬
tance between the clutch rod, elastic stop nut and the end
of the rod guide should be five-eights (5/8) inch as shown in
Figure 13.
7

Figure 13
4. With the elastic stop nut adjusted correctly on the clutch
rod depress the foot pedal all the way and adjust the set
collar at the rear of the spring so that the clutch rod spring
is just free to rotate on the rod. (See Figure 14)
Belt Stops:
If the main drive belt will not stop when the clutch is
depressed, the belt stops may need adjusting.
The belt stops on the tractor should be adjusted so there is
one-sixteenth to one-eighth inch between the belt stop and
the belt when the belt is tight (clutch engaged). To adjust a
belt stop, loosen the bolt holding it, move the belt stop to
the proper position and re-tighten the bolt. Check the ad¬
justment after the bolt has been tightened. (See Illustration
Below)

Seat:
The seat may be adjusted from front to rear as desired by
repositioning the seat in any of the three sets of holes in the
seat support. Simply remove the nuts and lock washers
from the lower seat pan mounting bolts and reposition the
seat. Retighten the nuts securely.
Parking Brake:
See illustration below. To adjust the parking brake, loosen
the nut located behind the seat deck. Rotate the parking
brake handle clockwise to tighten and counterclockwise to
loosen the brake. The brake should be tight enough so it
will hold in reverse, yet be easily placed in the "locked"
position. Before retightening the locking nut, be sure the
brake handle is positioned in the 11 o'clock position when
engaged.
Power Take-Off Rod Guide Adjustment:
Should an attachment fail to drive properly, the power
take-off clutch may need adjusting. The power take-off
clutch is normally in proper adjustment when there is 7/8
inch distance between the set collar and the end of the
bracket when engaged for use with snow thrower and 5/8
inch for use with the rotary mower. If more tension is need¬
ed or readjustment is necessary, disengage the power take¬
off lever, loosen the collar set screw and slide the collar
back on the rod slightly. Engage the lever and check the
belt tension. Only enough tension to drive the implement
being used is necessary. Excess tension may cause premature
failure of belts and pulley bearings. M

MAINTENANCE
Regular maintenance of your riding tractor will greatly
increase it's useful life and reduce repair costs. See your
Briggs and Stratton manual for engine maintenance in addi¬
tion to the steps listed here.
EVERY FIVE HOURS
Before starting the engine and at least once very five hours
check the oil level in the engine crankcase. Turn the inspec¬
tion — fill plug counterclockwise to remove. Maintain the
oil at the full level. {See Figure 15}
Every 25 hours or oftener under extremely dusty condi¬
tions: All attachments should be removed from the tractor
and the following maintenance procedures performed:
1. Clean the Cooling System: In order to clean the engine
cooling system, it will be necessary to remove the two
thumb screws and turn steering wheel tight right, then pivot
hood forward. Clean all grass, chaff and dirt from the engine
fins and shrouds.
2. Change Engine Oil: Drain the crankcase when the engine
is warm. Remove the drain pipe can until all oil is drained,
then replace cap and tighten securely. Refill the crankcase
with a high quality detergent oil classified MS. Summer
(above 40°F.) use SAE 30. Winter (below 40°F.) use SAE
5W-20 or SAE 10W. It is very important that the engine is
serviced according to the season and temperature it will be
used in.
3. Clean the Air Cleaner: Turn the two screws on the air
cleaner cover counterclockwise to loosen. Remove cover
and foam element. Wash the foam air cleaner element in
kerosene or liquid detergent, squeezing several times and
dry it thoroughly. Saturate it with engine oil, squeeze sever¬
al times to distribute the oil and remove excess and rein¬
stall. Make certain the lips of the filter are in position when
installing.
4. General Lubrication: The five grease fittings on your
tractor should be greased with a lithium base automotive
type grease. Remove all dirt, grit and paint from the fitting
before greasing. A few drops of engine oil should be applied
to the points indicated. Do not allow oil to get on belts or
pulleys. (See Figures 16,17,18 & 19}
10

5. Check the Transmission Oil Level by removing the filler
and level plug at the rear of the transmission. Allow the
tractor to set for about 10 minutes after operation before
checking. Oil should be level with the bottom of the filler
and level hole. If necessary, add SAE 90 weight transmis¬
sion oil. Reinstall the plug securely. It is normally not
necessary, but if you wish to drain oil from the transmis¬
sion, the drain plug is located on the lower right side of the
transmission housing. (See Figure 20)
6. Check the Battery Water Level to insure it is maintained
at the battery ring or mark approximately one-fourth inch
above the plates. If water is needed, add distilled water just
before charging to mix the solution. Do not over fill the
battery. (See Figure 21)
NOTE
Initial filling of the battery will be with electrolyte,
thereafter top off when need with distilled water.
EVERY 100 HOURS OR ONCE A YEAR
1. R e move the spark plug, clean or replace and set the gap
at .030". Do not sand blast plugs, as the abrasive particles
left on the plug may damage the engine. Plugs may be
cleaned by scraping or wire brushing compressed air
2. R e move the battery cables. Always remove the negative
“ground" cable first and replace it last. Clean the battery
with soap and water to remove all dirt, oil and corrosion
from battery surface. Do not allow foreign material or
cleaning solution to get inside the battery. Clean the
terminals and cable clamps with a wire brush. Replace and
tighten snugly. After tightening, coat the terminals and
clamps liberally with grease or vaseline to inhibit corro¬
sion.
SERVICE
Battery Replacement:
A dead battery or one too weak to start the engine may not
necessarily mean the battery needs to be replaced. The fly¬
wheel alternator may not be charging properly. If there is
any doubt what is causing the problem, see your dealer. If
you need to replace the battery, proceed as follows:
1. Disconnect the battery cables, (remember to remove the
negative “ground" cable first), and remove the old battery
from the tractor.
2. Wash the battery mounting area and clamps with soap
and water. Remove corrosion from cable ends with a wire
brush. Check the new battery to be sure it is filled with the
special electrolyte to the rings or marks and the vent holes
in the filler caps are open.
3. Carefully place the new battery in the tractor. Fasten
the battery hold down clamp and connect the cables. Con¬
nect the (+) positive cable first.
4. After tightening the cable clamps, put a liberal coat of
grease or vaseline on them to inhibit corrosion.
Belt Replacement:
1. Depress the foot pedal to remove tension from the belt
and remove the old belt.
2. Install the new belt insuring it is twisted in the same
manner. The part of the belt leaving the left side of the
engine drive pulley goes to the bottom side of the transmis¬
sion pulley.
3. Check the belt finger adjustments and the adjustments
of the clutch rod. See Adjustments Section on pages 7 and
8 .
GENERAL REPAIR
To prevent rusting, sand off and paint any parts which
become chipped or damaged. Apply a good rust preventa¬
tive to all bare metal parts. Keep all fasteners and guards
tightened securely.
OFFSEASON STORAGE
When the tractor is to be stored without use for a period of
two months or longer, the following precautions should be
11

taken to insure the tractor will be ready to go when you
need it.
1. Drain the fuel tank completely by running the tractor
until it stops. This may be easily done by removing the gas
line at the carburetor and draining the tank thru this hose.
If you desire, fuel may be stored in the tank or a small
container if a good brand of gasoline stabilizer is used. This
additive, available from your dealer, prevents formation of
gum and varnish for up to one year, providing easier start¬
ing and a clean fuel system.
