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 in figures
1 through 4.
IGNITION SWITCH: (Figure 1, item F) 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, hourmetcr, etc. will op¬
erate. Turn the key clockwise past the ON position to the
START position to actuate the starter. THE TRANSMIS-
SION SHIFT LEVER MUST BE IN THE NEUTRAL POSL
TION AND THE POWER TAKE OFF CLUTCH CONTROL
LEVER (S| MUST BE IN THE DISENGAGED POSITION
BEFORE THE STARTER WILL ACTUATE. Release the
key as soon as the engine starts. Return the key to the ver¬
tical position to stop the engine. CAUTION: ALWAYS RE-
MOVE THE IGNITION KEY WHEN CLEANING, ADJUST'
IN G, O R SE RVI Ct NO TH E TRACTOR 0 R ANY ATTACH¬
MENT OR WHEN LEAVING THE VEHICLE UNAT'
TENDED.
CHOKE CONTROL KNOB: (Figure 1, item E) The
choke control knob may be pulled out to increase the a-
mount of fuel entering the engine for starting and cold wea*
ther warmup. When starting a cold engine in cold weather
pull the choke all the way out. Some choke may be required
to start the engine when the air temperature is above 70 de¬
grees F or while the engine is still warm from being recently
run. 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 SUFFI¬
CIENT EVEN IN COLD WEATHER.
GENERATOR WARNING LIGHT: (Figure 1, item
H) The generator light will warn you if the genera tor or
voltage regulator on your tractor is not functioning proper¬
ly. It is normal for the generator light to come on when the
ignition switch is in the ON position and the engine is stopped
or running at low speed. The light should go out when the
engine is running at higher speeds. If it does not the genera¬
tor or voltage regulator is not functioning properly. Check
the generator belt adjustment as described on page 14. See
your Simplicity dealer if the light will not go out after the
belt is adjusted.
HQURMETER: (OPTIONAL) (Figure 1, item J)
The hourmeter is useful in keeping accurate maintenance
records and telling how much time the tractor has been
used on a particular job. It operates anytime the ignition is
turned on whether the engine is running or not-
FUEL GAUGE AND FILLER CAP: (Figure 1,item A)
The fuel gauge indicates fuel level- BEFORE ADDING
FUEL SHUT OFF THE ENGINE AND ALLOW JT TO
COOL SEVERAL MINUTES, Turn the cap counter¬
clockwise to remove it and add fuel. The 3 gallon capacity
provides about 3 hours of mowing. Use leaded or non-
ieaded REGULAR grade automotive gasoline. CAUTION:
DO NOT ALLOW LIGHTED CIGARETTES, MATCHES,
ETC., AROUND ANY OPEN GASOLINE CONTAINER.
DO NOT OVERFILL; WIPE UP ANY SPILLED GASO
LINE.
LIGHT SWITCH: (standard equipment on Sovereign]
Optional on Landlord) (Figure 1, item D) 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 unauthorized
persons, the ignition switch must also be in the ON position
for the lights to operate. To turn 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 LI FT SWITCH: (OPTIONAL) (Figure 1,
item B) The power lift switch controls the electrically opera
ted power lift unit. Push the toggle switch forward to raise
a front d 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 toggle
switch. The height indicator (Figure 6 r item A) on the leR
side of the tractor shows attachment position. The lift
motor will ratchet when it has reached the end of its travel.
Ratcheting is not harmful to the unit, but releasing the tog¬
gle switch as soon as ratcheting begins will prevent unnee-
essary wear. If the motor is allowed to ratchet for an ex¬
tended period of time, a circuit breaker will open, discon¬
necting power to the lift motor. It will automatically reset
after about a minute.
CLUTCH AND BRAKE PEDAL: (Figure 1, item I)
Depressing the pedal will first disengage the tractor drive
clutch. As you continue to depress the pedal, the brakes will
be applied to stop the tractor. The clutch-brake pedal mai
be depressed for shifting transmission gears, but it is not nec¬
essary if the shuttle drive control lever (Figure 1, item G) is
in the neutral position.
SHUTTLE DRIVE CONTROL LEVER (Figure l,
item G) The position of this lever determines whether the
tractor moves forward or reverse or remains stationary. It
can also he used for short periods of time to reduce tractor
travel speed in either forward or reverse, or used to stop
tractor travel by pulling it toward the opposite position.
Although the tractor may be shifted into or out of any gear
by depressing the clutch-brake pedal, it may be shifted
more rapidly by placing the shuttling control lever in the
center NEUTRAL position as shown in figure 1. The brake
which is automatically applied when this lever is in neutral,
stops "spinning" of the transmission input shaft to facil¬
itate shifting.
After shifting the four-speed transmission into the desired
gear, the tractor can be driven FORWARD by pushing the
shuttle drive control lever ahead and locking it in the for¬
ward position. To drive in REVERSE pull the shuttle drive
control lever back and lock it in the reverse position. For a
particular transmission gear, the tractor will drive the same
speed in reverse as forward. The shuttle drive control lever
may be moved from forward to reverse or reverse to forward
without waiting for the tractor to stop moving. To prevent
sudden change of direction and unnecessary wear to the
dutches, the shuttle drive control lever should he moved
slowly into either drive position.
The tractor may be "inched" or slowed for working in tight
areas by holding the shuttle drive control lever part way to¬
ward the locked drive position. This can be done for short
periods of time without damage, however, constant slipping
of the drive clutches will cause them to wear and require
frequent adjustment.
SPEED CONTROL LEVER: (Figure 1, item C) 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 back 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 5, and the Operation Chart on page 7.
TRANSMISSION SHIFT LEVER: (Figure 2, item A)
The transmission shift lever is used to select the desired trans¬
mission gear. There are four drive positions. Using the shut¬
tle drive unit, the tractor will move either forward or reverse
in any of the gears. The approximate ground speed in miles
per hour for each gear at full engine speed (3600 RFMjboth
forward and reverse are shown below:
GEAR
MAXIMUM GROUND SPEED
First
.96 MPH

sired gear. To shift into second or fourth, pull the shift lever
back toward you and more it to the left or right.
Do not attempt to move the shift lever unless tractor move¬
ment is stopped and either the shuttle drive control lever is
in neutral or the clutch-brake pedal is depressed. The trans¬
mission shift lover must be in the neutral START position
for the engine starter to operate.

lever can be moved as desired and locked into position. See
the owners manual for any attachment you may be using
for specific information on how the lift lever should be
used.
PARKING BRAKE LOCK: (Figure 2, item B) To
lock the parking brake, grasp the lock and pull it upward
and back until the handle rests against the footrest as
shown In figure 2. To releaso pull the top portion away
from the footrest and down. It should be locked in the up
position to prevent the tractor from rolling whenever the
operator leaves the tractor seat. Remember to release the
parking brake before driving the tractor,
POWER TAKE OFF CONTROL LEVER: (Figure
2, item C) This lever controls power to center or rear mount¬
ed attachments , such as a mower or rotary tiller. Full the
lever up and move it forward until it snaps over center to
engage the power take off. Pull it back and down to dis¬
engage. Always move the power take off control lever all
the way to the disengaged or engaged position. The tractor
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 disen¬
gaged before the engine will start.
MANUAL LIFT LEVER: (Figured item A) The lift
lever is used for raising or lowering attachments such as the
rotary mower or the tiller for transport. The operating
height of attachments, can be regulated by using the notch¬
es and pin holes provided. The thumb button (B) on top of
the handle disengages the catch from the quadrant so the
DUAL LIFT LEVER: (OPTIONAL) (Figure 4,
item A) The dual lift Lever provides a convenient means of
operating a front mounted attachment such as a snow

thrower or a. snow plow and dozer blade independently of
center or rear mounted attachments. A good example is
using the rotary tiller and dozer blade in leveling a ground
surface. Both attachments can he mounted to the tractor
at the same time, and the operator can conveniently raise
or lower each of them from the tractor scat.
BEFORE OPERATING THE TRACTOR
Though your Simplicity Dealer may have performed the be¬
fore starting checks listed below, we suggest that yon 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.
TIRE INFLATION: The tires should be checked and
inflated to the proper pressure before operating. Front tires
should have 12 to 15 PSl of air and rear tires 6 to 8 PSI of
air.
CRANKCASE OIL: Before starting the engine, insure
the engine crankcaso is filled with the correct grade and
weight of oil. See page 17 in the Maintenance section of this
manual for instructions on checking the oil and the correct
oil to use.
FUEL SUPPLY: Fill the fuel tank completely with
clean fresh leaded or non-leadcd regular grade automotive
gasoline. (Do not mix oil with gasoline). Premium gaso¬
lines are not recommended as they increase carbon deposits
in the engine. CAUTION: GASOLINE IS HIGHLY FLAM
MABLE- NEVER ALLOW ARTICLES SUCH AS LIGHTED
MATCHES, 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 SEEN
ALLOWED TO COOL BEFORE ADDING FUEL.
BEVEL GEAR BOX OIL: See figure 3S, Remove
the pipe plug (A) from the elbow at the rear of the gear
case. Oil should be present at the bottom of the filler elbow.
If it is not, add 90 weight transmission oil 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 18, 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
section of this manual.
TRANSMISSION OIL: See figure 34, Remove the
pipe plug (A) to check the oil. The oil should he level with
the bottom of the threads. If it is not, add 90 weight trans-
minion oil until it is level with the bottom of the hole
threads.
LUBRICATION: Lubricate all grease jerks and pivot
points according to the Every 25 Hour Maintenance in¬
structions on page 17 of this manual. A pisto-luber grease
gun specially designed for this purpose is available from your
Simplicity dealer.
ATTACHMENTS: Read and become familiar with the
Owners Manual for any attachments you are using with
your tractor,
SEAT ADJUSTMENTS: The seat should be adjusted
so the operator can comfortably depress the clutch and brake
pedals while sitting back in the seat. See page 9 in the Ad¬
justment section of this manual if the seat requires adjusting.
STARTING THE ENGINE
1. Refer to the Instruments and Controls section beginning
on page 2 of this manual for the location and use of the in¬
struments and controls. CAUTION: IT 1$ DANGEROUS
TO START THE TRACTOR UNLESS YOU ARE SEATED
IN THE TRACTOR SEAT. Insure that the power take off
clutch control lever (s) are in the disengaged position, and
the transmission shirt lever is in the neutral START position.
2. Move the engine speed control lever to midway belween
slow and fast-
3. Pull 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 will be re¬
quired.
4. Depress the clutch brake pedal and hold it down to dis¬
engage the transmission drive. Although the engine may be
started without disengaging the clutch, in cold weather it
will start easier with the clutch disengaged since the starting
motor will not have to turn the transmission in addition to
the engine.
5. Insert the ignition key and turn it to the right past the ON.
position to the START position to actuate 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
any choking. Tf 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 recemly.
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 position.
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 ports.
3. Turn the ignition key counter-clockwise 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
5

the transmission shift lever and/or the engine speed control
lever or for short periods by the shuttling drive lever,
ENGINE SPEED
Attachments driven by the power take off operate best at a
particular speed. The engine speed control should be ad-
justed to set the attachment speed for the operation being
performed and the tractor transmission used to control tra¬
vel speed. The engine speed control is one means for con¬
trolling ground speed when pulling light loads or transport¬
ing the tractor.
TRANSMISSION SHIFT LEVER
See the chart on page 7 for selecting the gear recommended
for performing various jobs.
Operations such as snow throwing or lawn revitalizing can
be performed more quickly by using a low forward speed
and higher reverse speed. First and third gears are opposite
each other and it is simple to "flip shift" with the shutting
speed control in neutral using first for forward and third
for reverse.
STARTING TRACTOR TRAVEL
Assure yourself that the area in which you are going to drive
the tractor is free of obstructions Insure the shuttle drive
control lever is in the NEUTflAL position, then shift the
four-speed transmission into the desired gear. It is not nec¬
essary to depress the clutch-brake pedal to shift gears if the
shuttle drive control lever is in the neutral position.
Release the parking brake and look around to insure there
are no obstructions in your path. To start the tractor in mo¬
tion, move the shuttle drive control lever SLOWLY forward
or back from the neutral position until it locks in the for¬
ward or reverse position,
STOPPING TRACTOR TRAVEL
Tractor motion may be stopped either with the shuttle drive
control lever or the dutch-brake pedal. To stop the tractor
forward travel use the shuttle drive control lever, move the
lever to the NEUTRAL position and then slowly toward
the REVERSE position. As soon as the tractor stops mov¬
ing, place the shuttle drive control lever in neutral. If you
wish to stop the tractor while it is moving in reverse, push
the shuttle drive lever past neutral slowly toward the for¬
ward position.
In emergencies or if both hands are required on the steering
wheel, depress the clutch-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 and fan screen clean and
free of obstruction which would decrease air flow to and
from the engine. See page 15 for cleaning instructions.
2. Insure that you are using the proper grade and weight of
oil in the engine for the temperature where the tractor is be¬
ing used- Check the oil level each time you 511 the fuel tank.
DO NOT OVERFILL THE CRANKCASE - ENGINE
OVERHEATING MAY RESULT.
3- 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.
4, 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 3G°F.
check the following items closely:
1. Use the correct grade an d weight of oil for the temperature
conditions. Change the oil only when the engine is warm. If
an unexpected temperature drop occurs when the engine is
Tilled with summer oil, before starting the engine, move the
tractor to a warm location until the oil will flow.freely,
2. Use fresh fuel. Fill the fuel tank after each days use to
protect against moisture condensation.
3. Disengage the dutch when starting the engine.
4. Install the heat deflector furnished with the snow throw¬
er 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 fan screen and cooling fins dean and
free of materials which will decrease air Jlow.
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 he
changed more often than 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 fud tank is
empty, add a good brand of gasoline stabilizer. This additive,
Stnbilj available from your Simplicity dealer, prevents form¬
ation 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 times, then reinstall the
spark plug.
4. Clean the air cleaner element as described on page 19, of
the Maintenance instructions.
5. Plug the exhaust outlet to prevent the entrance of mois¬
ture, dirt, butp, 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
G

shown in the Maintenance section.
&. If the tractor is to be stored 6 months or longer block the
tractor up off tha wheels to relieve weight and keep the tires
off a damp floor. Protect the tires from prolonged exposure
to direct sunlight.
9. Store the tractor in a dry place indoors.
STARTING THE TRACTOR AFTER STORAGE
Before starting the tractor after storage, do the following:
1. Remove the blocks from tinder the tractor.
2. Replace the battery*
3. Unplug the exhaust outlet.
4. Perform the Before Operating instructions on page 5.

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 arq 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 in open to provide easy access to areas
requiring lubrication, adjustment, or repair.
RAI51NG THE TRACTOR HOOD
See figure 6. The tractor hood is hinged at the front by two
spring loaded bolts. It may he 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
7. Lift upward on the back of the hood to raise it as shown.
The hood raised in this position provides easy access to the
generator, battery, fuel tank, engine, etc,
RAISING THE SEAT DECK
See figure 8, The tractor seat deck is hinged at the back.
To raise the seat deck, reach under it from each side and pull
the two lacking levers [B) to the outside. As you hold the
locks out raise the seat deck as shown in figure 9. Raising the
seat deck in this manner will expose many of the transmission
adjustment and maintenance areas.

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 disen¬
gage tbe clutch. If adjustment is required proceed as follows:
1. See figure 15. Use one open end wrench to hold nut (A)
stationary, and another wrench to turn nut (B) counter’
clockwise to loosen it slightly.
2. Turning nut {A) 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 nrial and error
method, and operating the tractor eacb time an adjustment
has been made. The best adjustment can be made by turn¬
ing nut (A) counter-clockwise until the foot pedal brake does
not work. Then turning it clockwise, one turn at a time,
until the tractor will stop satisfactorily when rolling back¬
ward. This is the correct adjustment. Further tightening may
cause the brake to drag, or prevent proper clutch disengage¬
ment.
3. After you are satisfied that the adjustment is correct use
one wrench to hold nut (A) stationary and another turn nut
(B) clockwise to tighten the nuts securely together.
PARKING BRAKE ADJUSTMENT
Although the transmission may help prevent the tractor from
rolling when it is in gear and the engine is stopped, the park¬
ing brake should be properly adjusted and used whenever the
operator leaves the tractor seat. The parking brake is actua¬
ted 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:
L See figure 16. 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.
Loosen nut (A) by turning it clockwise.
2. See figure 16. After insuring the tractor is either on a
level surface or the wheels are blocked so it will not roll,
pull forward on the parking brake handle (B) to disengage
the parking brake.
3, Rotate parking brake handle (B) clockwise to tighten the
parking brake, or counter-clockwise to Loosen it. Turn tbe
brake one complete revolution when making any adjust-
Figune 16. Perking brake adjustment on left side of tractor;

ment- 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 16, with
the handle at approximately the one o'clock position as
you face it from the front of the tractor,
4, A fter 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 transmission
shift lever is in neutral or will actuate when the transmission
shift lever is not in the neutral position, the neutraE safety
starting switch may need adjusting. The power take off
lever (s) must be disengaged before the starter will operate
also. Adjust the transmission safety start switch as follows:
1. R aise the seat deckas explained on page 9 under Raising
the Seat Deck.
2- Place the transmission shift lever in the neutral START
position.
3. See figure 17. The neutral safety start switch is properly
adjusted when it is centered on surface (C) and depressed
□ bout 1/16” to 1/3”, The two nuts (A) may be turned
clockwise or counter-clockwise to lower or raise the safety
switch and bracket (B) is slotted to allow it to be centered
on surface (C). After adjusting the neutral safety switch
place a film of grease on surface (C) where it contacts the
switch-
4, Tighten the two nuts (A) against mounting bracket (B),
5, Lower the seat deck.
6. Cheek the adjustment by starting the tractor.
POWER TAKE-OFF CLUTCH ADJUSTMENT
See figure 18. The power take off clutch is properly adjusted
when pulley (A) moves 1/S” when the power take off com
trol lever is engaged and disengaged. If adjustment is re¬
quired, proceed as follows:
1. Raise the scat deck, by following the instructions on page
9 under Raising the Seat Deck,
2. Place the power take off clutch control lever [figure 2,
item C) in the engaged position,
3. Observe the movement of pulleys (A) in relation to cup
Figure 17. Neutral safety start switch located under spat
deck.
Figure 18. Power take off clutch.
(B) as the power take off control is moved slowly from the
engaged to disengaged position. If the pulleys [A) move more
or less than 1/6', adjustment is required-
4- Turn the rear most nut at (CJ counterclockwise to loo^
sen it slightly. To increase the amount pulley (A) travels him
the nuts at (G) clockwise. To decrease travel of pulley (A),
turn the nuts counter-clockwise. Adjust the nuts at (C) and
observe 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 1/8" Lighten the rear most nut al
(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 (s) are disengaged and the transmission shift lever
is in neutral, or will actuate when Lhe power take off lever
is in the engaged position, the power take off neutral safety
starting switch may need adjusting. It is located under the
tractor frame, but since the tractor frame is open on the
bottom, it can be easily reached from under the tractor. If
adjustment is required proceed as follows:
1 T Place the power take off control lever (figure 2, item C)
in the disengaged position. ■
2, See figure 19. Locate the safety switch fD) which is lo¬
cated under the tractor frame,
3, See figure 19. The safety switch can be moved up or
down by turning the two nuts (A) clockwise or counter¬
clockwise, or forward or back by sliding it in the stot in
mounting bracket (B).

6. Check the adjustment by starling the tractor. The starter
should actuate when the power take oH control lever is in
the disengaged position but should not actuate when the
power take off control lever t£ in the engaged position.
STARTER-GENERATOR BELT ADJUSTMENT
See figure 20. If the starter turns, hut the engine does not
rotate, the starter generator belt may need tightening. Pro¬
ceed as follows:
1- Raise the tractor hood as explained on page 9 under
Raising the Tractor llood-
2. S ee figure 20. Loosen slightly the two nuts (A) cap screw
(0) and nut (C). Use a pry bar (D) similar to the one
shown between the generator and engine block to apply
pressure to the generator and tighten the belt. The belt
should be Light enough so thumb pressure at (£} will de¬
flect it about 3/4 r ' -
3- While holding the pry bar to maintain tension 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 (C) and apply more tension to
the belt.
5. Tighten the two nuts at (A) and the cap screw(B) securely.
6. Lower the hood anti 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
tampered with.
INITIAL ADJUSTMENT
Initial adjustment will permit the engine to be started and
warmed up prior to final adjustment- Proceed as follows:
1. S ee figure 21. Turn the needle valve (A) clockwise until
it just closes CAUTION: VALVE MAY B£ DAMAGED
Figure 20- Generator located on right side of engine,
BY TURNING IT IN TOO FAR.
2. Open the needle valve (A) one and one half turns coun¬
ter-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. Start the.engine and run it at full speed.
2. See figure 21. 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
engine runs smoothly.
3. Move the engine speed control lever to the slow position,
and set the idle spaed adjusting screw (C) 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¬
clockwise (rich) until the engine idles smoothly.
4. Reset the idle speed so the engine idles at 1200 RFM. Push
the engine speed control lever forward to the Tast position,
the engine should accelerate without hesitation or sputtering.
If the engine does not accelerate property, readjust needle
valve (A) to a slightly richer mixture.

MAINTENANCE
Your Simplicity tractor has been designed and manufactured
to give yen many years of dependable operation. In order
for it to give you efficient trouble free service over a long
period of time the maintenance opera lions 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 oT attachments and accessories permit uso of
your tractor throughout the year. BECAUSE YOUR TRAC¬
TOR IS A MULTI-SEASON TOOL r JT IS VERY IMPORT¬
ANT TO SERVICE THE ENGINE FOR THE SEASON IN
WHICH IT WILL BE OPERATED. Be sure to change to
winter grade oil before making cold weather starts.
Whenever you are cheeking fluid levels in any area of the
tractor, the readings will be much more accurate if the tractor
is setting on level ground. We have provided the Scheduled
Maintenance Chart on page IS as a convenient means for
you to know which services should be performed at various
times. You shouldj of course, refer to the detailed explana¬
tion of how to perform each maintenance task until you
are familiar enough with it to perform it correctly from
memory.
Refer to your Briggs and Stratton operating and mainten¬
ance instructions for more specific detail on servicing the
engine.
ORDERING REPLACEMENT PARTS
Replacement parts required for performing maintenance ser¬
vices or repair work should be purchased from your Simpli¬
city dealer. When ordering parts be prepared to give him the
tractor and engine identification numbers. If yon have not
already recorded these numbers on the inside front cover of
this manual, we suggest that you do so now for convenient
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 problem could prevent a costly
breakdown later.
CHECK ENGINE CRANKCASE OIL LEVEL: Sea
figure 22. If the engine has been running, allow a minute or
two for the oil to drain down into the crankcase before

If it should be necessary to drain the axle housing, the drain
plugis located at (B). Always tighten it securely when replac¬
ing to prevent oD leakage.
CHECK BEVEL GEAR BOX OIL LEVEL: See
figure 35- The check and fill plug for the bevel gear box is
located at (A). Remove it to check the oil level. The bevel
gear box is properly filled when oil is visible at the bottom
of the elbow. If filled to the top of the elbow, oil may be
forced out the vent plug Located on top of the bevel gear
housing. If oil is required, add SAE 90 weight transmission
oil. Fill only until oil can be seen in the bottom of the pipe
elbow. I fit should be necessary to drain the bevel gear hous¬
