INSTRUMENTS AND CONTROLS-HOW TO
UNDERSTAND AND USE THEM
Picture yourself seated on your Landlord or Sovereign trac¬
tor. Before starting the engine^ lets learn how to understand
and use the instruments and controls. The paragraphs refer¬
ring to the instruments and controls are illustrated on fig'
ures 1 through 5.
IGNITION SWITCH: (Figure 1, item E) To actuate the
ignition switch first insert the ignition key as shown. When
the key is turned clockwise to the first position, the ignition
is ON. In the ON position the lights, hourmeter, etc. wQl op¬
erate. Turn the key clockwise past the ON position to the
START position to actuate the starter. THE HYDROSTA¬
TIC TRANSMISSION CONTROL LEVER MUST BE IN
THE NEUTRAL POSIT I ON AND THE POWER TAKE OFF
CLUTCH CONTROL LEVER MUST BE IN THE DISEN¬
GAGED POSITION BEFORE THE STARTER WILL AC¬
TUATE. Release the key as soon as the engine starts. Return
the key to the vertical position to stop the engine* CAU¬
TION: ALWAYS REMOVE THE IGNITION KEY WHEN
CLEANING, ADJUSTING, OR SERVICING THE TRAC¬
TOR OR ANY ATTACHMENT OR WHEN LEAVING THE
VEHICLE UNATTENDED.
CHOKE CONTROL KNOB: (Figure 1, item DjThe
choke control knot may be pulled out to increase the
amount of fuel entering the engine for starting and cold
weather warmup. When starting a cold engine in cold wea¬
ther pull the choke all the way out. Some choke may be re¬
quired to start the engine when the air temperature is above
70 degrees F or while the engine is still warm from being
recently rum After the engine has started, push the choke in
slowly. In cold weather it may be necessary to leave the
choke pulled out slightly for three or four minutes while the
engine warms up. NEVER OPERATE THE ENGINE WITH
THE CHOKE OUT AFTER IT HAS HAD SUFFICIENT
TIME TO WARM UP - ABOUT 5 MINUTES SHOULD BE
SUFFICIENT EVEN IN COLD WEATHER.
2

GENERATOR WARNING LIGHT: (Figure L ItemF)
The generator light will warn you if the generator or voltage
regulator on your tractor is not functioning properly. It is
norrual for the generator light to come on when the ignition
switch is in the OK position and the engine is stopped or
running at low speed. The light should go out when the en¬
gine is tunning at high speeds. If it does not the generator or
voltage regulator is not functioning properly. Check the gen¬
erator belt adjustment as derdcribedon page 14-See your Sim¬
plicity dealer if the light will not go out arter the belt is ad¬
justed.
HOURMETER: (OPTI TjNAL) - (Figure 1, item G) The
hourmeter is designed to record the number of hours the en¬
gine runs. However, since it is electrically operated, it will
run any time the ignition switch is in the ON position even
though the engine may not be running. The hourmeter is use¬
ful in keeping accurate maintenance records, and also a con¬
venient way of telling how much time the tractor has been
used on a particular job.
FUEL GAUGE AND FILLER CAP: (Figure 1, item
A) The fuel gauge indicates thE amount of fuel in the tank.
Before adding fuel, shut off the engine and allow it to cool.
To remove the fuel <^uge and filler cap for adding gasoline,
tum the fuel filler gauge-cap counter-clockwise. The fuel
tank holds approximately 3 gallons - enough for about 3
hours of mowing. Use leaded or non-leaded "regular" grade
automotive gasoline. CAUTION: DO NOT ALLOW LIGHT¬
ED CIGARETTES, MATCHES, ETC., AROUND ANY
OPEN GASOLINE CONTAINER. DO NOT OVER FILL;
WIPE UP ANY SPILLED GASOLINE,
LIGHTSWITCH: (Standard equipment on Sovereign;
Optional on Landlord) (Figure 1, item C) The switch should
be moved up to the ON position to turn on the tractor
lights. To prevent the lights from being turned on by un¬
authorized persons, the ignition switch must also be in the
ON position for the lights to operate. To tum the lights off,
push the Light switch down to the OFF position. DO NOT
OPERATE THE LIGHTS FOR LONG PERIODS OF TIME
(MORE THAN 20 MINUTES) WHEN THE GENERATOR
LIGHT IS ON OR THE BATTERY MAY DISCHARGE
ENOUGH SO IT WILL NOT START THE ENGINE.
POWER LIFTSWITCH: (OPTIONAL) (Figure 1,
item B) The power lift switch controls the electrically oper¬
ated power lift unit. Push the toggle switch forward when
you wish to raise a front center or rear mounted attachment.
Pull it back toward you to lower the attachments. The power
lift will stop and hold in any position when you release the
toggleswitch. The height indicator (Figure 7 T item A) on the
left side of the tractor can be used to determine what posi¬
tion the lift is in. The lift motor will ratchet when it has
reached the end of its travel. Ratcheting is not harmful to
the unit, but you should release the toggle switch as soon as
ratcheting begins to prevent unnecessary wear. If the motor
is allowed to ratchet for an extended period of time, a circuit
breaker will open, disconnecting power to the lift motor. It
will automatically reset after about a minute.
CLUTCH AND BRAKE PEDAL: (Figure 2, itemA)
Depressing the pedal will first disengage the tractor drive
clutch. As you continue to depress the pedal, the brakes will
Figure 2. Controls on right side of tractor
be applied to stop the tractor. CAUTION: THE BRAKES
WILL NOT FUNCTION IF THE GEAR SHIFT LEVER
(Figure 5, Item A) at the rear of the tractor is in the neutral
position.
HYDROSTATIC TRANSMISSION CONTROL
LEVER: (Figure 2, Item BJThe Hydrostatic transmission
control lever regulates the direction and amount of oil (fluid)
pumped by the hydrostatic transmission pump to drive the
tractor, and is used to control both the direction of travel
and the ground speed of the tractor. NEUTRAL position
for the hydrostatic transmission control lever is as shown
with the back of the control lever resting against the notched
portion of the guide. The hydrostatic transmission control
lever must be in this neutral position for the engine starter
to operate.
To move the tractor FORWARD grip the control lever
squeezing the lock release lever toward the knob and move
the control lever forward. The gear shift lever (Figure 5,
item A) must also be in the drive position for the tractor to
operate. The farther forward from neutral the control lever
is pushed, the faster the tractor will move forward at a given
engine speed. To slow, or stop the tractor when it is moving
forwardj squeeze the lock release lever toward the knob and
pull the control lever rearward slowly toward the neutral
position. You can place the hydrostatic transmission in
neutral from the forward position without watching it by
slightly pushing to the right on the control Lever as it is
moved rearward. The control Lever will stop against the
notched portion of the guide when it reaches neutral.
To move the tractor in REVERSE, squeeze the trigger of the
hydrostatic control lever toward the knob, push the lever to
the left, and pull it back from the neutral position. The far¬
ther back the control lever is moved, the faster the tractor
will travel in REVERSE. To stop the tractor in reverse,
squeeze the trigger toward the knob and move it slowly to
the neutral position. In emergency situations, you may use
the clutch and brake pedal (Figure 2, item A) to stop.

PARKING BRAKE LOCK: (Figure 2, item C) To lock
the parking brake grasp the lock, and pull it upward and
hack until the handle rests against the foot rest as shown in
figure 2. To release pull the top portion away from the foot
restand down. It should be locked in the up position to pre¬
vent the tractor from rolling whenever the operator leaves
the tractor seat
SPEED CONTROL LEVER: (Figure 3, item A) The
engine speed control lever is used to set the desired engine
speed. The speed control lever should be moved forward a-
way from the operator to increase engine speed or beck to¬
ward the operator to reduce engine speed. Consult the ap¬
propriate section of this manual for specific information on
suggested settings of the engine speed control lever. For ex¬
ample: starting the engine, page 5. Controlling tractor
ground speed page 8, and the Operation Chart on page 8.
POWER TAKE OFF CONTROL LEVER: (Figure 3,
item B) This power take off lever controls power to center
or rear mounted attachments such as a mower or rotary til¬
ler which are driven by the power take off. Pull the lever up
and move it forward until it snaps over center to engage the
power take off. Pull it hack and down to disengage. The trac¬
tor engine should be running at 1/2 to full engine speed when
the power take off is engaged to absorb the added load.
CAUTION: ALWAYS DISENGAGE THE POWER TAKE
OFF, AND WAIT UNTIL ALL ATTACHMENTS HAVE
STOPPED MOVING BEFORE LEAVING THE TRACTOR
SEAT* THE POWER TAKE OFF CONTROL LEVER
MUST BE DISENGAGED BEFORE THE ENGINE WILL
START*
MANUAL LIFT LEVER: (Figure 3, item C) The lift
lever is used for lifting mounted attachments, such as the
rotary mower, or the tiller out of the operating position so
they can be transported. You can also regulate the operating
height of attachments, such as the grader blade, and snow
thrower, by using the notches and pin holes provided. The
thumb button (D) on top of the handle is provided to dis¬
engage the catch from the quadrant so the lever can be
moved forward or back as desired and locked into position.
See the owners manual for any attachment you may be us¬
ing with the tractor for specific information on how the lift
lever should .be used.
DUAL LIFT LEVER: (OPTIONAL) (Figured
item A) The dual lift lever provides a convenient means of
operating a front mounted attachment such as a snow
thrower or a mow plow and dozer blade independently of
center or rear mounted attachments. A good example is if
you wish to use the rotary tiller and the snow plow and do¬
zer blade in preparing a seed bed. Both attachments can be
mounted to the tractor at the same time, and the operator
can conveniently raise or lower each of them from the trac¬
tor seat.
GEAR SHIFT LEVER: (Figure 5, item A) The gear
shift lever located at the rear of tractors equipped with the
hydrostatic transmission is used to disengage the trans¬
mission from the rear axle. With the lever in the N EUTRAL
position, the tractor may be moved without engine power*
CAUTION: WHEN THE GEAR SHIFT LEVER IS MOVED
TO THE NEUTRAL POSITION THE BRAKES WILL NOT
FUNCTION. NEVER DISENGAGE THE SHIFT LEVER
IF TRACTOR IS ON AN INCLINE UNLESS THE TIRES
ARE PROPERLY BLOCKED. BE SURE THE TRACTOR
ENGINE IS STOPPED BEFORE ATTEMPTING TO EN¬
GAGE OR DISENGAGE THE GEAR SHIFT LEVER,
To engage, move the kver to the vertical position, as shown
in Figure 5 until it maps into the spring clip. Disengage the
shift lever by raising the spring lock up and pushing the
shift lever to the right as shown in figure 3D.

BEFORE OPERATING THE TRACTOR
Though your Simplicity dealer may have performed the be¬
fore starting checks listed below, we suggest that you per¬
sonally check each one so that you will become familiar with
them and also to insure that your tractor is ready to operate
the first time you use it.
elbow. If it is not, add 90 weight transmission oU until it is
visible in the bottom of the elbow-
Al R CLEANER; Insure that the air cleaner is in place
and properly sealed. If it is dirty, clean or replace it accord¬
ing to the instructions on page 17, in the Maintenance sec¬
tion of this manual.
BATTERY: Check the battery to be sure it is filled to the
proper level with electrolyte and the vent holes in each of
the filler caps are open. See page 19 in the Maintenance sec¬
tion of this manual.
AXLE HOUSING GIL: See figure 30. Remove the pipe
plug (A) to check the gih The oil should he level with the
top of the elbow, if it is not, add 90 weight transmission oil
until it is level with the top of the elbow.
LUBRICATION: Lubricate all grease Zerks and pivot
points according to the evtry 25 hour maintenance instruc¬
tions on page 17 of this manual. A pistoluber grease gun
specially designed for this purpose is available from your
Simplicity dealer.
ATTACHMENTS: Read and become fairui^r with the
Attachments Manual for any attachments you are udng with
your tractor.
SEAT ADJUSTMENTS: The seat should be adjusted so
the operator can comfortably depress the clutch and brake
pedal while sitting back in the seat. See page 10 in the Ad¬
justment section of this manual if the seat requires adjusting.
TIRE INFLATION: The tires should be checked and in¬
flated to the proper pressure before operating. Front tires
should have 12 to 15 PSI of air and rear tires 6 to 8 PSI of
air.
CRANKCASE OIL; Before starting the engine, insure
the engine Crankcase is filled with the correct grade and
weight of oil. See page 15 in the maintenance section of
this manual for instructions on checking the oil and the cor¬
rect oil to use.
FUEL SUPPLY: Fill the fuel tank completely with clean
fresh leaded or non-leaded regular grade automotive gaso¬
line. (Do not mix oil with gasoline}. Premium gasolines are
not recommended as they increase carbon deposits in the
engine.CAUTION: GASOLINE ISHIGHLY FLAMMABLE.
NEVER ALLOW ARTICLES SUCH AS LIGHTED MAT¬
CHES, OR CIGARETTES, WHICH COULD CAUSE IT TO
IGNITE NEAR OPEN GASOLINE CONTAINERS. DO
NOT OVERFILL WIPE UP ANY SPILLED FUEL. BE
SURE THE ENGINE IS NOT RUNNING AND HAS BEEN
ALLOWED TO COOL BEFORE ADDING FUEL.
TRANSMISSION: The transmission ail (fluid) level
should he checked and the transmission filled with Dexron
Automotive Transmission Oil to the oil Level plug. (Figure
31, item A).
TRANSFER GEAR CASE OIL: See figure 31. Re¬
move the pipe plug (D) from the elbow at the rear of the
gear case. Oil should .he present at the bottom of the filler
STARTING THE ENGINE
1. Refer to the Instruments and Controls section beginning
on page 2 of this manual for the location and the use of in¬
struments and controls. CAUTION: IT IS DANGEROUS TO
START THE TRACTOR UNLESS YOU ARE SEATED IN
THE TRACTOR SEAT. Insure that the power take off
clutch control lever is in the disengaged position, and the
hydrostatic transmission control lever is in the neutral posi¬
tion.
2. Move the engine speed control lever to midway between
slow and fast.
3. Prill the choke knob out. In cold weather pull it all the
way out. In warmer weather or when starting an engine
which is still warm from recent operation less choke w01 be
required.
4. Depress the dutch brake pedal and hold it down to dis¬
engage the transmission drive. Although the engine may be
started without disengaging the elutebi in odd weather it will
start easier with the dutch disengaged since the starting mo¬
tor will not have to turn the transmission ip addition to the
engine. Also depressing the dutch brake pedal provides ad¬
ditional safety in starting as the tractor can not move for¬
ward or backward unexpectedly when the engine starts.
5. Insert the ignition key and turn It to the right past the ON
position to the START position to engage the starter mo¬
tor. As you turn the key, check the Generator warning light
to see that it is functioning properly.
6. When the engine starts, release the key and allow it to re¬
turn to the ON position. Slowly push the choke in. After
the engine has run for a few minutes it should not require
5

any choking. If the engine does not start after about 10 sec¬
onds of cranking it may be receiving too rich a fuel mixture.
Push the choke in and try again. The engine may not need to
be choked when starting it in warm weather or if it has been
operated recently.
7. Release the clutch-brake pedal as soon as the engine is
running smoothly.
STOPPING THE ENGINE
1. Move the engine speed control lever to the SLOW posi¬
tion.
2. If the tractor has been operating under full load, allow
the engine to idle for about a minute to reduce the engine
temperature. Stopping a hot engine too suddenly can dam¬
age engine parts.
3. Turn the ignition key counterclockwise to the vertical
position to stop the engine.
4 Set the parking brake.
5. Remove the ignition key to prevent unauthorized use of
the tractor.
CONTROLLING TRACTOR GROUND SPEED
Tractor ground speed can be controlled by the position of
the hydrostatic transmission control lever and/or the engine
speed control lever.
ENGINE SPEED
Most power take off driven attachments operate best at a
particular speed. Since the speed of the power take off drive
is direedy related to the engine speed it is desirable to ad'
just the engine speed to control attachment speed and use
the hydrostatic lever to control ground speed. For pulling
light loads or transporting the tractor and attachments from
one area to another, adjusting the engine speed is one meth¬
od of controlling tractor ground speed.
HYDROSTATIC TRANSMISSION CONTROL
The hydrostatic equipped tractor is designed so that for¬
ward and reverse movement can be completely controlled
without the use of the clutch. Simply squeeze the control
handle and move it forward to start the tractor moving
ahead. To slow the tractor move the control to the rear. As
the control is moved further away from neutral the tractor
ground speed will increase. The clutch and brake pedal may
be depressed to stop the tractor at any time. It is very handy
to use the clutch to slow down for turns or when mowing
in confined areas when both hands are needed for steering.
STARTING TRACTOR TRAVEL
Assure yourself that the area in which you are going to drive
the tractor is free of obstructions. Release the parking brake
and look around to insure there are no obstructions in your
path- To start the tractor in motion T squeeze the trigger of
the hydrostatic control lever with your right hand, and move
it forward or back from the neutral position slowly until you
have reached the desired speed. Always move the hydrostatic
control lever slowly to prevent abrupt and dangerous speed
changes. CAUTION: DO NOT STOP OR START SUDDEN¬
LY WHEN GOING UP OR DOWN HILL. MOW UP AND
DOWN THE FACE OF STEEP SLOPES; NEVER ACROSS
THE FACE. REDUCE SPEEDONSLOPES AND IN SHARP
TURNS TO PREVENT TIPPING OR LOSS OF CONTROL.
EXERCISE EXTREME CAUTION WHEN CHANGING DI¬
RECTION ON SLOPES.
STOPPING TRACTOR TRAVEL
To stop the tractor squeeze the trigger toward the hydrosta¬
tic transmission control lever and move the lever slowly to¬
ward the NEUTRAL position. In emergencies or if both
hands are required on the steering wheel, you may depress
the clutch and brake pedal to stop the tractor. Before leaving
the tractor seat, shut off the engine, set the parking brake,
and remove the ignition key.
HOT WEATHER OPERATION
When operating the tractor at temperatures above 75*F pay
particular attention to the following items to prevent dam¬
age.
1. Keep the engine cooling fins dean and free of obstruction
which would decrease air flow to and from the engine. See
page 15 for cleaning instructions.
2. Keep the transmission oil (fluid) cooler clean and free of
dirt and chaff which would restrict air flow. Also keep the
cooler free of oil. An oil film on the outside of the cooler
greatly reduces its cooling ability. See page 15 for instruc¬
tions on cleaning the oil cooler.
3. Insure that you are using the proper grade and weight of
oil in the engine for the temperature where the tractor is be*
mg used. Check the oil level each time you fill the fuel tank.
DO NOT OVERFILL THE CRANKCASE - ENGINE
OVERHEATING MAY RESULT.
4. Check the battery water level more frequently than every
25 hours which is recommended under normal conditions.
High temperatures cause faster evaporation of water from
the battery.
5. Remove the carburetor heat deflector used with the snow
thrower or dozer blade.
COLD WEATHER OPERATION
When the tractor is being used in temperatures below 30° F,
check the following items closely:
1. Use the correct grade and weight of oil for the tempera¬
ture conditions. Change the oil only when the engine is warm.
If an unexpected temperature drop occurs when the engine
is filled with summer oil, before starting the engine, move
the tractor to a warm location until the oil will flow freely.
2. Use fresh ftiel. Fill the fuel tank after each days use to
protect against moisture condensation.
3. Disengage the clutch when starting the engine.
4. Install the heat deflector furnished with the snow thrower
or dozer blade if these attachments are to be used.
DUSTY OPERATING CONDITIONS
When the tractor is operated in dusty or dirty conditions
check the following items closely:
1. Keep the engine and transmission oil cooler fins dean and
free of materials which will decrease air flow.
2- Service the air cleaner more frequently- Clean or replace
it as often as necessary to allow air to flow to the carburetor
freely.
3- Change the engine oil more frequently. The oil should be
6

changed more often t han every 25 hours as is recommended
under normal conditions. In extremely dusty conditions,
change every 10 operating hours.
OUT OF SERVICE PROTECTION (Storage)
When the tractor is to be stored without use for a month or
longer, the following precautions should be taken to insure
your tractor will be ready to go when you need it:
1. Unless you wish to run the tractor until the fuel tank is
empty, add a good brand of gasoline stabilizer. This additive,
Statil, available from your Simplicity dealer, prevents for¬
mation of gum and varnish for up to one year, providing
easier starting and a cleaner fuel system.
2. Drain and refill the engine crankcase while the engine is
warm. Tie a tag on the tractor indicating what grade and
weight of oil was used.
3. Remove the spark plug and pour one ounce (two table*
spoons) of SAE 30 engine oil into the cylinder. Engage the
starter to turn the engine Over a few tunes, then reinstall the
sparkplug.
4. Clean the airdeaner element as described On page 19. of
the Maintenance instructions.
& ♦ Plug the exhaust outlet to prevent the entrance of mois¬
ture, dirt, bug?, etc.
6- Insure the battery is filled to the proper level with water
and is fully charged. Battery life will be increased if it is re*
moved and put in a cool dry place and fully charged about
Once a month.
7. Grease all grease Zerks and put oil on the lubrication
points shown in the Maintenance section.
B, If the tractor is to be stored 6 months or longer block
the tractor up off the wheels to relieve weight and keep the
tires off a damp floor. Protect the tires from prolonged ex¬
posure to direct siinlight.
9. Store the tractor in a dry place indoors.
STARTING THE TRACTOR AFTER STORAGE
Before starting the tractor after it has been stored, do the
following:
1. Remove the blocks from under the tractor.
2 Replace the battery,.
3. Unplug the exhaust outlet.
4 Perform the "Before Operating the Tractor" instructions
found on page 5 of this manual.

ADJUSTMENTS
Most of the adjustments described here are easy to perform.
Some of the adjustments require a little mechanical know¬
how and some special tools to do them well. You may wish
to have your Simplicity dealer make some or all of the ad¬
justments as they are required; however, we have given in¬
structions for them here as a convenience to you should you
wish to make them yourself. CAUTION: DO NOT AT*
TEMPT TO MAKE ANY ADJUSTMENTS WHILE THE
ENGINE IS RUNNING UNLESS REQUIRED IN THE IN¬
STRUCTIONS. IF THE ENGINE MUST BE RUNNING TO
MAKE AN ADJUSTMENT, BE CAREFUL TO STAY
CLEAR OF ANY MOVING PARTS.
The Landlord and Sovereign tractors have been designed for
easy accessibility to the areas which need to be reached in
making adjustments and performing maintenance- The un-
derside of the frame is open to provide easy access to areas
requiring lubrication, adjustment, or repair.
RAISING THE TRACTOR HOOD
See figure 7. The tractor hood is hinged at the front by two
spring loaded bolts, ft may be easily opened by releasing the
two rubber straps (B) located on either side of the hood. Pull
down and out on the straps to release them. See figure 8-
Lift upward on the back of the hood to raise it as shown. The
hood raised in this position provides easy access to the gen¬
erator, battery, fuel tank, engine, etc.
RAISING THE SEAT DECK
See figure 9- The tractor seat deck (A] is hinged at the back.
To raise the seat deck, reach under it from each side and pull
the two locking levers (B) to the outside. As you hold the
Figure 7, Left side of tractor.
Figure 8. Tractor hood raised for easy access.
locks out raise the seat deck as shown in figure ID. Raising
the seat deck in this manner will expose many of the trans¬
mission adjustment and maintenance areas.
SEAT ADJUSTMENT
See figure 10. The tractor seat is properly adjusted when the
operator can comfortably operate the clutch and brake pedal
while sitting back in the scat- The seat can be adjusted foa>
ward or back in any of four positions. If adjustment is re¬
quired, proceed as follows:
1. See figure 10; Position the seat deck as shown by foliow-
ing the instructions under Raising the Seat Deck on page 10.
2. Remove the two cap screws and lock washers at (A).
3. Remove the two nuts and lock washers at (B).
Figure 9. Seat deck release at front of seat deck.

Figure ID, Seat deck raised,
4. I f the seat is to be positioned in either of the two forward'
sets of mounting holes the two rubber spacers are placed over
the studs at (B) and used between the seat and seat deck. If
the seat is to be positioned in either of the two rearward po¬
sitions, the rubber spacers are placed over the studs (BJ, but
under the seat deck. Line the seat up with the desired holes
in the seat deck, and install the rubber spacers according to
the holes used.
5. Install the two lock washers and nuts at (B) and tighten
them securely.
6. Install the two cap screws and Lock washers at (A) and
tighten them securely.
7. Lower the seat deck.
CLUTCH FREE TRAVEL
See figure 11. The clutch free travel is correct when there is
1/3" between the nuts (A) and the rod guide when the
clutch brake pedal is released and pulled rearward as far as
it will go. If adjustment is required, proceed as follows:
1. Raise the seat deck ag shown in figure 10, by following
the instructions under Raising the Seat Deck on pagelO.
2. Using two wrenches hold the forward nut at (A) station¬
ary with one wrench while turning the rearward nut counter-
clockwise slightly with the other to separate them.
3. Pull rearward on the clutch brake pedal to insure it has
returned completely to the engaged position.
4. Turn the forward nut at (A) as necessary so that the dis¬
tance between it and the rod guide is 1/3” as shown in
figure 11.
5. Using two wrenches hold the forward nut at (A) station¬
ary while turning the rear one clockwise to tighten the two
nuts together securely.
6. Lower the seat deck.
HYDROSTATIC NEUTRAL ADJUSTMENT
If the tractor tends to creep {move slightly forward or back¬
ward} when the hydrostatic speed control lever is in the neu¬
tral position, proceed as follows:
1. Raise the seat deck by following instructions under Rais¬
ing the Seat Deck on page ID.
Z See figure 30. Raise the spring lock and move the gear
shift lever to the neutral position as shown.
3. See figure 11. Loosen the two locking nuts (B) on either
end of tumbuckle (C).
4. Start the tractor engine and set the engine speed control
so it runs at about 1/3 full speed
5. Make sure the hydrostatic speed control lever (Figure 2,
item B) is in the NEUTRAL position.
6. CAUTION: USE CARE WHEN WORKING AROUND
MOVING BELTS AND PULLEYS TO KEEP HANDS,
CLOTHING, ETC., FROM BEING CAUGHT IN THEM.
Use an open end wrench to rotate the tumbuckle (Figure 11,
item C) until the brake drum (Figure 12, item A} does not
rotate. When the brake drum does not rotate when the en¬
gine is running at 1/3 full speed, the hydrostatic neutral ad¬
justment is correct,
7. Shut off the tractor engine.
Figure 11. Clutch free travel and hydrostatic transmission

& See figure ll r After allowing the belt and pulleys to stop
turning, use two wrenches to tighten the locking nuts (B)
against turnbuckle (C). Tighten the locking nuts (B) one at a
time, while using the other wrench to hold turnbuckle (C)
from rotating.
9, Lower the seal deck- Place the shift lever in DRIVE posi¬
tion and check your adjustment while sitting in the tractor
seat by operating the engine at full throttle with the hydro¬
static lever in the neutral position,
FOOT PEDAL BRAKE ADJUSTMENT
The foot pedal brake should be adjusted so that it will stop
the tractor when it is moving backward, but not so tight to
prevent the foot pedal from traveling far enough to disengage
the clutch. If adjustment is required proceed as follows:
1. L ift the seat deck by following the instructions under
Raising the Scat Deck on pagelOt
Z See figure 12, Use one open end wrench to hold nut (B)
stationary, and another wrench to turn nut (C) counter¬
clockwise to loosen it lightly.
3. Turning nut (B) clockwise will give more braking action
and turning it counter-clockwise will give less. The brake ad¬
justment can best be made by using the trial and error
method, and operating the tractor each time an adjustment
has been made. The best adjustment can be made by turning
nut (B) counter-clockwise until the foot pedal brake does
not work. Then turning it clockwise, one turn at a time, un¬
til the tractor will stop satisfactorily when rolling backward.
Thisis the correct adjustment. Further tightening may cause
the brake to drag, or prevent proper clutch disengagement.
4. After you are satisfied that the adjustment is correct use
one wrench to hold nut (B) stationary and another to turn
nut (C) clockwise to tighten the nuts securely together.
5. Lower the seat deck.
PARKING BRAKE ADJUSTMENT
Although the hydrostatic transmission may help prevent the
tractor from rolling when the engine is stopped, the parking
brake should be properly adjusted and used whenever the
operator leaves the tractor seat. The parking brake is actu¬
ated and adjusted independently of the foot brake. It is cor¬
rectly adjusted when it will prevent the tractor from rolling
either forward or backward and some resistance is felt when
it is placed in the engaged position. If it is too tight, it will
be difficult to place it in the engaged position. To adjust the
parking brake, proceed as follows:
1. See figure 13. NOTE: ALL DIRECTIONS GIVEN FOR
ADJUSTING THE PARKING BRAKE, ARE AS IF YOU
ARE STANDING AT THE FRONT OF THE TRACTOR
LOOKING BACK TOWARD THE PARKING BRAKE. Loo¬
sen nut (A) by turning it clockwise,
Z See figure 13. After insuring the tractor is either on a level
surface or the wheels are blocked so it will not roll, pull for¬
ward on the parking brake handle (B) to disengage the park¬
ing brake.
3, Rotate parking handle (B) clockwise to tighten the park¬
ing brake, or counter-clockwise to loosen it- Turn the brake
one complete revolution when making any adjustment.
After turning the handle (B) one revolution place it in the
engaged position to check it for correct adjustment. The
correct engaged position is as shown in figure 13, with the
handle at approximately in the 11 o'clock position as you
Figure 13. Parking brake adjustment on right side of tractor,
face it from the front of the tractor.
4. After the correct adjustment has been made, use a wrench
to tighten nut (A) securely by turning it counter-clockwise.
TRANSMISSION NEUTRAL SAFETY
START SWITCH
If the engine starter will not actuate when the hydrostatic
control lever is in neutral, or will actuate when the hydro-
transmission control lever is not in the neutral position, the
neutral safety starting switch may need adjusting. The power
take off lever must be disengaged before the starter will
operate also. Adjust it as follows:
1. Raise the seat deck as explained on page 14 under Raising
the Seat Deck,
2. Place the hydrostatic transmission control lever back a-
gainst the neutral stop.
3. See figure 14. The neutral safety start switch is properly
adjusted when it is centered on pointer {C) and depressed
about 1/16" to 1/8". The two nuts (A) may be turned clock¬
wise or counter-clockwise to lower or raise the safety switch
and bracket (B) is dotted to allow it to be centered on
pointer (C). After adjusting the neutral safety switch place a
film of grease on pointer (C) where It contacts the switch.
4. Tighten the two nuts (A) against mounting bracket (C).
5. Lower the seat deck.
6. Check the adjustment by starting the tractor.
POWER TAKE-OFF CLUTCH ADJUSTMENT
See figure 15, The power take off clutch is properly adjusted
when pulley (A) moves 1/S” when the power take off con¬
trol lever is engaged and disengaged. If adjustment Is required,
proceed as follows:
1, Raise the seat deck, by following the instructions on page
14 under Raising the Seat Deck.
2- Place the power take off clutch control Lever in the en-
12

deck.
gaged position.
3. Observe the movement of pulley (A) in relation to cup
(B) as the power take off control is moved slowly from the
enraged to disengaged position. If the pulley (A) moves
more or less than 1/6" adjustment is required.
4. Tom the rear most nut at (CJ counter-clockwise to loosen
it slightly. To increase the amount pulley {A) travels turn the
nuts at (C) clockwise. To decrease travel of pulley (A), turn
the nuts counter clockwise. Adjust the nuts at {C) and ob¬
serve the travel of pulleys (A) as the power take off lever is
engaged and disengaged. When adjustment has been made so
the pulley (A) travels 1/3" tighten the rearmost nut at (C)
against the forward nut to lock them in place.
5. Recheck your adjustment.
6. Lower the seat deck
POWER TAKE-OFF NEUTRAL SAFETY
START SWITCH
If the engine starter will not actuate when the power take off
lever is disengaged and the hydrostatic control lever is in
neutral, or will actuate when the power take off Lever is in
the engaged position, the power take off neutral safety start'
mg switch may need adjusting. It is located under the trac¬
tor frame, but since the tractor frame is open on the bottom,
it can be easily reached from under the tractor. If adjust¬
ment is required proceed as follows:
1. Place the power take off control lever in the disengaged
position.
2 See figure 16. Locate the safety switch (A) which is lo¬
cated under the tractor flame.
3. See figure 16. The safety switch can be moved up or down
by turning the two nuts {A) clockwise or counterclockwise
or forward or back by diding it in the dot in mounting
bracket (B)<
4. Adjust the safety switch so it is centered on the cam sur¬
face (C) and the end of the switch moves about 1/8" when
the power take off control lever is moved from the disen¬
gaged to the engaged position.
5. Tighten the two nuts fA) against the mounting bracket
fB).
6. Check the adjustment by starting the tractor. The startEr
should actuate when the power take off control Lever is in
the disengaged position but should not actuate when the
power take off control lever is in the engaged position.

STARTER-GENERATOR BELT ADJUSTMENT
See figure 17. If the starter turns, but the engine does not ro¬
tate, the starter generator belt may need tightening. Proceed
as follows:
1. Raise the tractor hood as explained on page 10 under
raising the tractor hood.
2. See figure 17. Loosen slightly the two nuts (A) cap screw
(B) and nut (C). Use a pry bar similar to the one shown be¬
tween the generator and engine block to apply pressure to
the generator and tighten the belt. The belt should be tight
enough so thumb pressure at (E) will deflect it about 1/4".
3. While holding the pry bar to maintain tendon on the belt,
tighten the mounting bracket at {C) securely.
4. Actuate the starter to make sure the engine will rotate. If
it does not, loosen the nut at (0) and apply more tension to
the belt.
5. Tighten the two nuts at (A) and the cap screw (B) se¬
curely.
6. Lower the hood and lock it in place.
CARBURETOR ADJUSTMENT
The carburetor is adjusted at the factory and normally does
not need adjustment unless it has been disassembled or tam¬
pered with.
Figure IS. Carburetor adjustments.
INITIAL ADJUSTMENT: Initial adjustment will per¬
mit'the engine to be started and warmed up prior to final
adjustment. Proceed as follows:
1. See figure IS. Turn the needle valve (A) clockwise until
it just doses. CAUTION: VALVE MAY SE DAMAGED
BY TURNING IT IN TOO FAR.
2. Open the needle valve (A) one and one half turns counter*
clockwise.
3. Turn the idle valve (B) clockwise until it just closes-
4. Open idle valve (B) one half to three quarter turns.
FINAL ADJUSTMENT
1. See figure 30. Move the transmission shift lever to the
NEUTRAL position, so the tractor will not creep forward
or back when the engine is running.
2. Start the engine and run it at full speed.
3. See figure IS. Turn needle valve (A) clockwise until en¬
gine misses, {Lean mixture), then turn it out (counter¬
clockwise) past the smooth operating point, until the engine
runs unevenly (Rich mixture). Now turn needle valve (A) to
the mid-point between the rich and lean mixture so the en¬
gine runs smoothly.
4. Move the engine speed control lever to the slow position,
and set the idle speed adjusting screw fC) so a fast idle is ob¬
tained (1200 RPM). Hold the throttle in this idle position
and turn the idle valve (B) clockwise (lean) and counter-
closkwise (rich) until tbe engine idles smoothly.
5. Reset the idle speed so tbe engine idles at 1200 RPM.
Push the engine speed control lever forward to tbe fast po¬
sition, the engine should accelerate without hesitation or
sputtering. If the engine does not accelerate properly, read¬
just needle valve (A) to a slightly richer mixture.

MAINTENANCE
Your Simplicity tractor has been designed and manufactured
to give you many years of dependable operation- In order
for it to give you efficient, trouble free service over a long
period of time the maintenance operations listed here must
be performed on a regular basis, The optional hour meter
provides an accurate method of determining when these ser¬
vices need to be performed.
A wide variety of attachments and accessories permit use of
your tractor throughout the year. BECAUSE YOUR TRAC¬
TOR IS A MULTI-SEASON TOOL, IT IS VERY IMPORT¬
ANT TO SERVICE THE ENGINE FOR THE SEASON If
WHICH IT WILL BE OPERATED. Be sure to change to
winter grade oil before making cold weather starts.
Whenever you are checking fluid levels in any area of the
tractor, the readings will be much more accurate if the trac¬
tor is setting on level ground. We have provided the Scheduled
Maintenance Chart on page 20 asa convenient means for you
to know .which services should be performed at various times.
You should, of course, refer to the detailed explanation of
how to perform each maintenance task until you are familiar
enough with it to perform it correctly from memory.
Refer to your Briggs & Stratton operating and maintenance
instructions for more specific detail on servicing the engine.
ORDERING REPLACEMENT PARTS
Figure 19. Checking the engine oil at ri^ht front of tractor.
Replacement parts required for performing maintenance
services or repair work should be purchased from your Sim¬
plicity dealer. Whan ordering parts be prepared to give him
the tractor and engine identification numbers. If yog have
not already recorded these numbers on the inside front
cover of this manual, we suggest that you do so now for con¬
venient future reference.
EVERY 5 HOURS OF OPERATION
INSPECT THE TRACTOR AND ENGINE: Make a
general Inspection of the tractor and engine Looking for loose
bolts, oil Leaks, low tire pressures, etc. A few minutes spent
correcting a small profflem could prevent a costly breakdown
later.
CHECK ENGINE CRANKCASE OIL LEVEL: See
figure 19. If the engine has been running, allow a minute or
two for the oil to drain down into the crankcase before
checking the oil level. Proceed as follows:
1. See figure 19. Turn the engine oil filler cap-dipstick (A)
counter-clockwise and lift it out,
Z Wipe the oil from the dipstick with a clean cloth.
3. Replace the filler cap dip-stick in the filler pipe and turn
the cap clockwise locking It into position.
4. Remove the filler cap dip-stick and check the oil level on
the dip stick,
5. If the oil is below the full line (B) shown in figure 19, add
enough oil to bring the oil Level up to the full mark- Use the
same grade and weight of Oil which is already in the engine.
DO NOT OVERFILL THE CRANKCASE.
6. R eplace the filler cap-dipstick (A) and tighten it securely.
EVERY 25 HOURS OF OPERATION
CLEAN TRANSMISSION 01L COOLER: See figure
20. Use a screw driver to remove plug (A). Inspect the oil
cooler (B) and if necessary remove any dirt, chaff or oil,
which may decrease the efficiency of the cooler. Dirt and
chaff collected on the outside of the cooler can usually be
brushed off after the engine has been stopped. Be careful not
to bend the coaler fins. If grass, chaff, or dirt collect between
the fins, it may be necessary to use air or water pressure to
blow it out. A non-fl amma ble solvent should be used to re¬
move any oil which may collect on the outride of the cooler.
In warm or dusty operating conditions, or when mowing dry
dry grass, the cooler may need to be cleaned more often to
prevent foreign material from restricting air flow through it.
CLEAN ENGINE FINS AND SCREEN: See figure
21. The blower screen (A) must be kept relatively free of
chaff, grass, etc., which would restrict the flow of cooling
air to the engine. Material which collects can normally be re¬
moved with a brush after the engine is shut off. The screen
may need to be cleaned more often when mowing dry grass.
Bee figure 23. All grass and chaff should be removed from the
engine fins {A}; C AUTI ON: TH E ENG1NE FINS ARE VE R Y
HOT AFTER THE ENGINE HAS BEEN OPERATED, DO
NOT TOUCH THEM UNTIL THE ENGINE HAS BEEN
ALLOWED TO COOL. NEVER SPRAY WATER ON A
