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.
