INTRODUCTION
This manual contains operational, maintenance and adjustment instructions for Power King Model 1620
garden tractors.
We urgeyou to read itthoroughlyand to understand its contents completely. Properuse and
careful attention to routine services and preventive maintenance practices are important factors in the
continuing satisfactory performance
of the tractor.
It is agood idea to record the
model and serial number of your tractor as soon as yo get it. This will
make it easier to order repairparts if needed, and to identify the tractor ifstolen. Spaceis provided in this
manual for that purpose.
Certain references are made in this manual
to right or left sides of the tractor. This is determined by the
direction the operator is facing when positioned in the tractor's seat.
A
number of safety interlock switches have been incorporated in this tractor. They are provided to
protect the operator in various stages of starting and running the tractor. Be certain that these switches
are in operation at all times.
IMPORTANT NOTE FOR OWNERS LIVING IN CALIFORNIA: The engines on these t actors are NOT
equipped with spark arresting mufflers. Use of this equipment in grass, brush or forest land without a
properly maintained and functioning exhaust spark arrester is in violation of California State Law
Section 4442 PRC.

CONTROLS
Be sure you are familiar with and know how to
operateeach ofthetractor's controls before attempt-
ing to start and run it
BASIC TRACTOR
Refer to the callout reference in Figure 2to identify
and locate each of the tractor's controls.
1. IGNITION SWITCH. This is athree position, key
actuated switch. Turn the key all the way to the
right into the "START" position to start engine.
When released, the key will automatically return
left to the "ON" position. Turn key left to the
"OFF" position to stop engine.
2. HEADLIGHTSWITCH. When ignition switch key
is in the "ON" position, this knob controls the
tractor's headlights. Pull knob outto turn head-
lights on, push in to turn them off. (Note: Head-
lights will also go off when ignition key is turned
to "OFF" position.)
3. THROTTLE LEVER. This lever controls the
amount of fuel being fed into the engine. Moved
upward, the engine's speed (rpm) will increase.
The speed will decrease when the throttle lever
is moved downward. Set lever midway between
the fast position (indicated by arabbit symbol)
and slow position (indicated by aturtle) when
starting engine.
4. PTO CLUTCH SWITCH. This starts and stops
the electromagnetic clutch for the Power Take-
Off on the front of the engine. The switch
engages the clutch when pulled out and pushed
"ON", and disengages it when pushed "OFF".
5. CHOKE KNOB. By cable extension this knob
controls the'uel-air mixture in the engine's
carburetor. The knob should be pulled outwhen
starting the engine and then pushed in shortly
after engine begins to run
6. STEERING WHEEL. Controls the frontwheels of
the tractor for steering.
7. BRAKE PEDALS. The left pedal controls the left
wheel brake and the right pedal controls the
right wheel brake. Pedals can be operated to-
gether as asingle unitby rotating the brake latch
arm on the back of the left pedal into the notch
on the right pedal forthe normal modeof opera-
tion (such as mowing). Each pedal can be oper-
ated independently as left or right wheel brakes
for turning with aheavy load or for tight turns.
Individual brakes ca also be used to stop one
wheel from spinningon ice or otherpoortractive
material. Always apply bra es gradually.
8. SPEED AND DIRECTION CON ROL LEVER.
The hand operated control lever is used to
"START" and/or "STOP"travel of the tractorand
toselect its forward or reverse operating speeds.
Forward speeds can be adjus ed from 0to 7.4
mph and reverse speeds from 0 to 3mph. The
neutral ("N") position as adetent.
I\. WARNING: Always make certain the speed
.. and direction control lever is in the neutral
detent before starting or getting off the tractor.
Makecertain that clothing
or other objects do not
hook onto the lever when getting off the tractor.
9. SPEED OVERRIDE PEDAL. T epedal attheleft
of the console is used for neutral safety starts
and speed over-ride adjustments while travel-
ling. As the pedal is depressed. speed slows and
as it is released, the speed as selected by the
hand lever will be resumed (this is similar to a
cruise control function).
10. PARKING BRAKE. Fully depressing the brake
pedals, once they are locked together with the
brake latch, encounters the par ing brake arm
which automatically latches and holds the
pedals in their depressed position. (Note: When
brakes are in this position. engine may be
started or will continuerunning withoutoperator
being in seat ifthe transmission is in neutral and
the PTO clutch switch is down.) Alight down-
ward tap on the latch releases the pedals.
11. HOOD LATCH. Retains the lower edges of the
hood preventing bounce on rough terrain.
12. ADJUSTABLE SEAT. Contoured seat may be
movedforward or rea ard up to3". Loosen two
wingnuts on t e seat support plate and slide
seat assembly back or forth to suit Tighten
wingnuts.
BYPASS VALVES
When the tractor is to be hand pushed, the appro-
priate "FWD" (forward) or "RE .(reverse) bypass
valve must be pushed do nand held down. Insert a
small screwdriver or similar object into the desired
actuator hole and depress he alve ac uator, hold
down while pushing the rac or.

LIFT CONTROLS
THE HYDRAULIC LIFT CONTROL LEVER is located
on the lowerright side of the dashboard. The lever is
connected through the dashboard sheet metal to a
single-spool hydraulic control valve, and has four
10
operating positions: (1) "Hold" position is in the
center.
(2) Pulled to the rear, both front and rear
mounted implements will be raised. Released, the
lever will automatically return to its center position
and the implements will hold theirraised position.
(3)
Pushedforward, both frontand rear implements will
be lowered and, again, the lever will return to its
center position when released. And
(4) Pushed fully
forward, through aslight detent, will allow the
implements to "float," or seek their own best oper-
ating level.
In this case, the lever will remain in the
forward position until pulled out of the detent.
An auxiliary lift kit is also available which, when
installed
in addition to the standard hydraulic lift
system above, will allow rear mounted implements
to be raised or lowered separately and independ-
ently of front
or mid-mounted implements. Control
lever action is the same as described above.

TRACTOR OPERATION
Your Power King Tractor is equipped with safety
devices which HELP prevent unsafe starting and
operation. However, there is no substitute for good
judgement. PERFORM the daily inspection and
maintenance desc ibed in the maintenance portion
of this manual.
NOTE: Safety interlocks prevent the engine from
starting unless: the speed override pedal
is fully
depressed, the operator
is in the tractor seat, PTO
switc
is "OFF".
ENGINE
CANNOT BE STARTED UNLESS:
1. Speed override pedal is depressed.
2. PTO switch is OFF (DOWN).

SETTING TRACTOR AND
ATTACHMENT IN MOTION
ACAUTION: Check to be sure that the area
~ around the tractor and attachment, and in
the path you intend to travel,
is clear of people,
pets and other obstructions.
1. To bring the tractorinto motion, movespeed and
direction control hand lever slowly from its
detent (Neutral) position to the desired speed
and direction.
2. To change acontinuous operation speed set-
ting, use the speed and direction control lever.
To temporarily reduce speed, use the speed
override pedal.
3. If aPTO driven attachment, such as arotary
mower,
is being used, engage the electromag-
netic clutch, pushing the
PTa switch to "ON"
before moving the speed and direction control
lever out of neutral or increasing engine rpm.
After both engine and attachment are running,
gradually increase engine rpm up to operating
speed. Refer to specific attachment instructions
for additional information.
NOTE: Asafety interlock switch automatically
stops the
PTa driven attachment if the operator
dismounts
without first pushing the PTa clutch
switch to "OFF" and engaging parking brake
latch
4. Operate throttle as required. Engine speed
below half throttle is not recommended since
PTO driven attachments are designed to oper·
ate at 2400 to 3100 rpm. However, the
lower the
engine speed, the longer your engine will last,
provided itis notso
low thatthe engine "strains"
under load.
SELECTING TRACTOR
SPEED RANGE
Tractor ground speed requirements will vary with
the
conditions under which the tractor is to be oper-
ated and the attachment being used. The
PTa
driven attachment drive is independent of the trans-
mission setting so the tractor may
be slowed down
without reducing the speed of the attachment The
speed over-ride pedal may be used to slow down the
tractor without braking. When the speed over-ride
pedal
is released, the tractor will resume speed as
selected by the speed and direction control hand
lever.
12
DRIVING THE TRACTOR
1. Stay away from ditches, holes, banks and other
areas that could cause tractor turnover.
2. Go slowly and use extreme caution on slopes,
grades and rough terrain, when turning
around
and when view of the ground is obstructed.
3. When operating on slopesandgrades, use front
and rear wheel weights and low speed ranges.
4. Usefront ... "heelweightsorfrontbumpercounter-
weights when pulling loads. Use
low speed
ranges and apply
power slowly. Pull from frame-
mounted towbar only. Do not pull from any other
place on the tractor frame.
5. Observeall safety rules printed atthe beginning
of this manual. (See page
4)
6. Never dismount until tractor is stopped, all
power shutoffand parking brake latch engaged.
7. Never leave the tractor unattended with the
engine running.
8. Never leave the ignition key in an unattended
tractor.
9. Do not disconnect any safety interlocks. They
are provided for the protection
of the operator,
especially when his
or her attention may be
momentarily distracted.
STOPPING THE
TRACTOR AND ENGINE
1. To stop motion of the tractor, return the speed
and direction control hand lever in "Neutral"
detent position. Lock both brake pedals together
and latch them
into the engaged position. Push
the
PTa clutch switch to "OFF" position.
NOTE: Safety interlocks will be actuated and
engine will stop automatically if these steps are
not taken before operator leaves seat.
2. Allow the engine to idle down for at least 60
seconds and then turn ignition key to the
"OFF"
position.
"DIESELING" ENGINE pull

position.

PREVENTIVE MAl TENANCE
GENERAL
The tractor should be checked and serviced at
regularintervals.Some checks and servicesshould
be made daily; other checks may be performed at
longer intervals.Alittle time spenteach daywill help
in keeping maintenance costs down and will make
the tractor safer to operate. Regular inspection of
thetractorwill help locate minorproblems thatneed
attention. Prompt correction of minor trouble can
prevent an accident or breakdown later.
MAINTENANCE LOG
It is a good idea for the owner to keep alog
recording maintenance and repair activities on his
tractor. Accurate records can be helpful in deter-
mining the length of time between maintenance
operations.
CLEANING
Keep the tractor free of debris, dirt and grease.
Remove mud, ice or snow from the tractorafter use
to prevent hardening or freezing. Be sure screens
are clear. Cleaning may help in the discovery of
minor difficulties before they become troublesome.
The side panels covering the oil coolers should be
removed and the coolers washed off to prevent
clogging.
LUBRICATION
Refer to the lubrication chart for lubricants and
service intervals. Always clean the exposed areas
of the dipstick, filler plugs, grease fittings, and the
areas around these parts before lubricating or
checking lubrication.
NEW TRACTOR FIRST USE LUBRICATION
Detailed descriptions and photos in this section
should be read and referre to when using the
following summary.
1. Check engine cran case i. differential, and
axle oil fill levels. Chec ba eryele rolyte levels.
NOTE: The use of brea - r non-detergent oil
is NOT recommended.
2. Use for 5hours in lightto medium dutyserviceto

Maintenance and repair supplies referred to below
can be obtained at automotive parts dealers or
discount store automotive departments.
Use apremium paste wax on hood, body and dash
areas every 6months
in order to maintain asmooth
surface finish and color.
Use of
"rubbing" compound can remove small
scratches. Touch up paint may be required for larger
damage.
Major damage can be repaired easily and inex-
pensively with an automotive body fiberglass repair
kit and touch up paint.
ENGINE
NOTE: If differences are encountered, the engine
manufacturer's Owner's Manual should override
the following.
The three main causes of major engine failure are:
1. No oil or dirty oil.
2. No cooling air.
3. Dirty carburetor air.
CHECKING OIL
Dipstick and oil fill are on top of engine. See Figure
M-1 on page 18.
To check level, pull dipstick completely out of the
crankcase,
wipe off oil, reinsert dipstick completely
into the oil, remove and read level.
Oil should be maintained between low
(L) and full (F)
marks. Do not overfill.
CHANGING OIL
The engineoil and filter should be changed afterthe
first 5hours of operation, and every
25 hours
thereafter
Drain oil while engine
is hot. Hot oil drains more
freely, and carries away more impurities. Remove
engine drain plug and filter. Drain oil into pan.
Replace plug and filter. Refill
to full (F) mark on
dipstick. Clean up spilled oil.
AIR CLEANER
Aclogged air cleaner reduces engine power and
leaves unburned fuel in the engine.
The air cleaner
is either oftwo types: a dry elementfilter with afoam
pre-cleaner around it, or a dry filter element alone.
If so equipped, clean the pre-cleaner daily, or more
often in dusty conditions. Water and detergent may
be used only on the foam pre-cleaner. Lightly oil
after cleaning.
14
The dry element removes dust as air circulates
through its
porous paper surfaces. Replace element
if rubber gaskets or paper surface is damaged.

6. Reassemble.
ENGINE COOLING SYSTEM
The tractor engine is air cooled. Air is drawn intothe
area
around the engine from the rear by fins
provided on the flywheel.
To prevent the engine
from overheating or burning out, the rotating air
screen and the cooling fins on each
block and
cylinder head must be kept clean and unobstructed
at all times.
To check this, proceed as follows:
1. Unlatch and raise Fiberglass hood section.
2. Check the engine intake screens and oil cooler
compartment located between the console and
engine. Clean if needed. Adirty screen will
cause theengine tooverheat.
See "Transmission
Oil Cooler," page 16.
3. Remove air duct around the muffler and clean
the
cooling fins on the engine. Be careful not to
touch the mufflerif cleaning is
done immediately
after use. Replace the duct.
4. Close and latch the hood.

SPARK PLUGS
Afterevery 100 hours of use check the condition of
each spark plug and reset the gap. The gap gradu-
ally widens
as the electrodes wear under normal
conditions. Check each plug
as follows:
1. Open the hood, disconnect the lead wire from
thetop ofthe plug.
2. Before removing plug, clean it and the area
around it
.to prevent dirt from dropping into
engine.

4. Check condition Of electrodes. If the plug has a
lightcoating ofgrayortan, this usually indicates
normal conditions. Awhite, blistered coating
may
indicate overheating. A black coating
usually comes from operating with
an over-rich
fuel mixture.
5. Do not attempt to service aspark plug that is
badly fouled or in poor condition. Replace both
plugs when one requires replacement.
6. Ifthe old plug is in good condition, reset the gap
to .025 inch.
7. Using atorque wrench, tighten each plug of the
twin cylinder engine to 10-15 ft-Ibs.

BATTERY CHARGING
WARNING: Dangerous Acid,
Explosive Gases
Batteries contain sulphuric acid. Avoid contact with
skin, eyes, andclothing. Batteries
produce explosive
hydrogen gas while being charged. Ventilate the
area when charging the battery. Keep cigarettes,
sparks, open flame,
and other sources of ignition
away from battery at all times. Keep batteries and
acid out of the reach of children. Remove all jewelry
when working on battery.
A. CAUTION: Do not apply 12-V DC to kill
~ terminal of ignition module as module will
burn out.
TRANSMISSION OIL COOLERS
The hydrostatic transmission oil is cooled in oil
coolers. These coolers must be kept clean and
unobstructed to prevent overheating of the trans-
mission.
To clean:
1. Unlatch and raise the hood.
2. Remove the protective sheet metal panels at
both sides ofthe coolercompartment. Each side
16
panel is retained by four screws, lockwashers,
and flat washers.
See Figure MS, page 18.
3. Use abrush and/or water under moderate pres-
sure to clear
out the oil cooler compartment.
4. Visually inspect the cooler fins and carefully
remove any debris caught between the fins.
Separate any fins which are touching each
other.
5. Replace the side screens and mounting hard-
ware and close and latch the hood.
HYDRAULIC OIL FILTER
The transmission oil filter should be replaced every
100 hours. Gain access to the filter from beneath the
tractor. Unscrew the filter and replace with anew
filter. See Figure

WHEELS AND TIRES
TIRE CARE
Proper tire maintenance is oneof the most important
factors in the satisfactory performance of your
tractor. Observe the following tire care rules for best
results:
1. Immediately wipe spilled oil or gasoline from
tires. Do not park in spilled oil. Petroleum
products attack rubber. Clean chemicals from
tires
as soon as possible.
2. Avoid sharp objects which may cut or puncture
tires.
3. Avoid "bruising" tires by striking hard objects
with heavily loaded tractor or at high speeds.
4. Do not "spin" tires during start-up.
5. Do not brake to skidding stops.
6. Maintain proper inflation:
•
Under-inflation may cause rim slipping,
excessive wear and alow or uneven
cut when
mowing. An under-inflated tire may appearto be
properly inflated but will buckle when the tractor
pulls aload and sidewalls will eventually break.
•Over-inflation may cause the rear wheels to
slip under load and cause faster tire wear as a
smaller part
of the tire is in contact with the
ground. When operating amower, the cut will be
higher than setting.
• A
correctly inflated tire results in good traction
with the least wear. The recommended pressure
may vary, depending upon the load on the
tractor wheels.
TREAD WIDTH
Tread width, as used here, refers to the spread or
spacing between the
center lines of the two rear
wheels or the two front wheels of the tractor.
When moving on slopes
or rough uneven ground, it
is important to have as wide aspread as possible
between the wheels. This makes the
tractor more
stable and reduces the possibility
of a"rollover."
REAR WHEELS.
To increase the tread width from
the standard position,
mount the right rear wheel on
the left side and the left rear wheel on the right side.
Switching wheels from one side to the other will
maintain the
proper direction of tire rotation.
FRONT WHEELS. Except for those equipped
with
wide 8-10 tires, these wheels may also be turned
around to widen the tread width.
ADDING WHEEL WEIGHTS
Added weight to the front and/or rear wheels can
make
tractor operation easier and safer under
certain conditions.
REAR WHEELS: Added
weight on the rear wheels
will be helpful:
1. When pulling. The weights will give added
traction and reduce slippage.
2. In maintaining traction with aheavy load at the
front of the tractor, such as with a Snowblower
or Bulldozer Blade.
FRONT WHEELS. Fron
bumper counterweights or
wheel weights on the front wheels will be helpful:
1. In balancing the lifting ac ion caused by rear
mounted attachments.
2. In keeping the front wheels from rising when
driving up aslope.
3. When pulling heavy loads on rough ground.
Wheel weights should be used in pairs to give an
equal
amount of added weight on each side of the
tractor. Operating with
weight on only one side will
cause uneven tire wear and tend to
tip the tractor.
This can cause
improper operation of some
attachments such
as arotary mower.
NOTE: Do
not exceed 3 weights per wheel, 6
bumper counterweights or any combination of
loads that will exceed the rated tire capacity.
LIQUID. A75% calcium
chloride solution can be
used in tires to add wheel
weight in lieu of wheel
weights.
Consult your Power King Tractor dealer
about
liquid ballasting procedure.
DUAL REAR WHEELS. Spacer kitsareavailable that
allow the addition of an extra wheel to the outside of
each rear wheel. Dual rear wheels will increase
stability and add traction.
CHANGING WHEELS
To remove awheel and tire, first remove any wheel
weights.
Block the other wheels to prevent the
tractor from rolling. Raise the tractor with ajack
under the frame. Remove wheel bolts and carefully
slide the wheel and tire from the tractor.
TIRE CHAINS
CAUTION: When tire chains are used,
purchase and install achain guard around
the speed and direction control lever
to prevent
the broken chain from changing setting.
19

TRACTOR STORAGE
When you do not plan to use your tractor for an
extended period of time, it should be stored in a dry
and protected place. unnecessary exposure to sun,
wind, rain or snow may have harmful effects on its
appearance and could shorten its usual service lite.
ENGINE
When properly prepared for each storage period the
engine will have alonger useful life. It will also be
ready for use with a minimum of preparation after
the storage period.
1. Referring to the lubrication section of this
manual, change the crankcase oil. Run the
engine long enough to thoroughly warm the old
oil in the crankcase before draining.
2. Run the engine for about 5minutes after adding
new oil supply.
3. Close the fuel shutoff valve and run engine until
fuel in carburetor is used up.
4. Using a pairof notched pliers on the hoseclamp,
disconnect the fuel line from the fuel shutoff
valve. Drain fuel line
5. Reopen the fuel shutoff valve and drain fuel tank.
When empty, remove fuel filter from valve and
wash out as required. Reinstall valve and replace
in tank. It is important to perform these fuel line
functions because gum will eventually form in
the tank, line, and carburetor if the system is not
used. Gum in the carburetor jets and passages
makes engine starting difficult Gum can be
dissolved with acetone or a50-50 mixture of
alcohol and benzol.
6. Remove each spark plug and pour 1tablespoon
of lUbricating oil of good quality into the
cylinder. Crank the engine 2 or 3times to
distribute the oil over the cylinder walls.
7. Recheck the gap and reinstall each plug.
TRACTOR
1. Wash, clean, wax the hood and body sections
and completely lubricate the tractor. (See
lubrication section of this manual.)
2. Paint rust-preventative oil over any area where
raw metal is exposed (except pulley grooves).
Do not use crankcase oil as it is not arust
preventative.
3. Remove the batteryand clean any corrosion that
may have accumulated around the posts. Store
the battery on arack or bench in acool, dry-
place. The battery should then be checked every
30 to 60 days while in storage and should be
recharged if necessary. When a battery
becomes discharged the electrolyte contains
more water than acid. In this discharged
condition, the battery could freeze and possibly
crack during cold winter weather
4. Place jacks or blocks under the tractor so that
the load is off the tires. Store the tractor so that
the tires are protected from directsunlight.lfthe
tractor cannot be placed on blocks, check the
tires at regular intervals and reinflate as
necessary to keep them at recommended
pressure.
NOTE: It is advisable that the tractor be started up
and driven at least every 6 months to maintain
critical lubrication coverage on moving parts.

ADJUSTME
TS AND REPAIRS
ENGINE CARBURETOR
Lack ofpoweraccompanied by black sooty exhaust
smoke usually indicates that the fuel mixture
is too
rich. Aclogged air cleaner can cause the same
symptoms. Check the air cleaner first. The carbure-
tor may not need adjustment.
An engine manufacturer's Owner's Manual
is in-
cluded with
your tractor. Please refer to it for any
other engine adjustments.
BODY REMOVAL
Although the following adjustments may be made
from underneath the tractor, it may be desirable to
remove the rearfender/body.
To dothis followthese
steps:
1. Disconnect the seat safety interlock wire. Expe-
diteservicing by removing seat for betteraccess
to bolts.
2. Remove 2nuts, lockwashers, and washers hold-
ing body to frame and the 2screws at the run-
ning board.
3. Unscrew and remove the speed and direction
control lever knob.
4. Remove gas tank cap.
5. Remove the hydraulic tank cap.
6. Tiltbodysection upand forward, overthespeed
and direction control lever and lift straight up
and off.
7. Replace gas and hydraulic tank caps.
TRACTION CREEP ADJUSTMENTS
After aperiod of time the tractor may "creep" for-
ward
or in reverse when the speed and direction
control lever
is in neutral and/or when the speed
override pedal
is fully depressed. (See Figure 5.)
Likely reasons for such creeping are:
1. The speed over-ride pedal reach rod may require
adjustment.
2. The speed and direction control lever may not
be fully seated in its neutral detent.
3. The cam follower may not be fully seated in the
cam detent.
4. Acombination of two or three of the above.
