SAFE OPERATION PRACTICES
TRAiNING
1. It is suggested that this manual be read in its
entirety before attempting to assemble or
operate this unit. Keep this manual in a safe
place for future reference and for ordering
replacement parts.
2. Your rotary mower is a precision piece of
power equipment, not a plaything. Therefore,
exercise extreme caution at all times.
3. Read this Owner’s Manual carefully. Be
thoroughly familiar with the controls and the
proper use of the equipment.
4. Never allow children to operate a power
mower. Only persons well acquainted with
these rules of safe operation should be al
lowed to use your mower.
5. Keep the area of operation clear of all per
sons, particularly small children and pets.
Stop engine when they are in the vicinity of
your mower. Although the area of operation
should be completely cleared of foreign ob
jects, a small object may have been over
looked and could be accidently thrown by the
mower in any direction and cause injury.
PREPARATION
1. Thoroughly inspect the area where the equip
ment is to be used. Remove all stones, sticks,
wire, bones and other foreign objects which
could be picked up and thrown by the mower
in any direction and cause injury.
2. Do not operate equipment when barefoot or
wearing open sandals. Always wear substan
tial footwear.
3. Do not wear loose fitting clothing that could
get caught on the mower.
4. Check the fuel before starting the engine.
Gasoline is an extremely flammable fuel. Do
not fill the gasoline tank indoors, while the
engine is running, or while the engine is still
hot. Wipe off any spilled gasoline before start
ing the engine as it may cause a fire or explo
sion.
5. Disengage the self-propelled mechanism or
drive clutch on units so equipped before start
ing the engine.
6. Never attempt to make a wheel or cutting
height adjustment while the engine is run
ning.
7. Mow only in daylight or in good artificial light.
8. Never operate the equipment in wet grass.
Always be sure of your footing. Keep a firm
hold on the handle and walk, never run.
OPERATION
1. Do not change the engine governor settings
or overspeed the engine. Excessive engine
speeds are dangerous.
2. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times as the rotating blade can cause in
jury.
3. Stop the blade when crossing gravel drives,
walks or roads. 3
FOR WALK-BEHIND MOWERS
4. After striking a foreign object, stop the
engine, remove the wire from the spark plug,
and thoroughly inspect the mower for any
damage. Repair the damage before restarting
and operating the mower.
5. If the equipment should start to vibrate abnor
mally, stop the engine and check immediately
for the cause. Vibration is generally a warning
of trouble.
6. Stop the engine whenever you leave the
mower, before cleaning the mower housing,
and when making any repairs or inspections.
7. When cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and
keep the wire away from the plug to prevent
accidental starting.
8. Before attempting to unclog the mower or
discharge chute, stop the engine and be sure
the blade has stopped completely. The cut
ting blade continues to rotate for a few
seconds after the engine is shut off. Never
place any part of the body in the blade area un
til you are sure the blade has stopped rotating.
Disconnect the spark plug wire and keep the
wire away from the plug to prevent accidental
starting.
9. Do not run the engine indoors.
10. Shut the engine off and wait until the blade
comes to a complete stop before removing
the grass catcher or unclogging chute.
11. Mow across the face of slopes, never up-anddown. Exercise extreme caution when chang
ing direction on slopes. Do not mow ex
cessively steep slopes.
12. Always disconnect electric mowers (line
operated) before cleaning, repairing or ad
justing.
13. Never operate mower without proper guards,
plates or other safety protective devices in
place.
14. Keep washout ports and other mower-housing
service openings closed when mowing.
MAINTENANCE AND STORAGE
1. Check the blade and engine mounting bolts at
frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be
sure the equipment is in safe working condi
tion.
3. Never store the equipment with gasoline in
the tank inside of a building where fumes may
reach an open flame or spark. Allow the
engine to cool before storing in any
enclosure.
4. To reduce fire hazard, keep the engine free of
grass, leaves, or excessive grease.

HI^note
For shipping purposes your mower
is set with the wheeis in a low cut
ting height position. For best
results, raise the cutting position
until it is determined which height
is best for your lawn. See adjust
ment section.
BEFORE STARTING ENGINE
1. Before starting engine, lubricate the blade
spindle assembly. Refer to lubrication sec
tion.
2. Check lockout control lever for proper opera
tion. If too great a pressure is needed to
operate this control, damage can be done to
the mechanism and the rod. Readjust so only
slight pressure is needed to operate the blade
engaging control. See control rod installation
section of assembly instructions.
3. Fill sump with oil using a high quality
detergent oil classified “For Service SC, SD,
SE or MS.” Nothing should be added to the
recommended oil.
4. Fill fuel tank using clean, fresh regular grade
automotive gasoline. Fill tank completely!
DO NOT MIX OIL WITH GASOLINE.
TO START ENGINE
1. Move lockout lever to “OFF” position. See
figure 11.
2. Move throttle control lever to “CHOKE” posi
tion. See figure 11.

3. Crank engine. Move throttle control to
“FAST” position as soon as engine fires. Use
choke as needed to keep engine running dur
ing warm up period.
Page 8
4. Put blade into motion by moving lockout lever
to “ON” position.
To engage the blade with the engine run
ning. ..
a. Move the throttle control lever to “FAST”
position.
b. Engage the blade engagement handle
(lockout lever) SLOWLY.
c. Adjust engine speed.
TO STOP
1. The blade is stopped by moving the lockout
lever to the “OFF” position.
2. The engine is stopped by moving the throttle
control lever to “STOP” position.
3. Disconnect the spark plug wire and ground
against the engine to prevent accidental start
ing while equipment is unattended.
A brief break-in period is essential to insure max
imum engine and mower life. This consists of run
ning the engine at half speed for a period of time
required to use one tank of gasoline. It is also
recommended to change crankcase oil after the
first five hours of operation or as operating condi
tions dictate. Always check oil before operating
the mower. BE SURE CRANKCASE IS FULL.
Proper lubrication must be maintained at all
times.
Appropriate clothing should be worn when cutting
brush or heavy weeds. Safety shoes and safety
glasses are highly recommended.
Be sure that lawn is clear of stones, sticks, wire,
or other objects which could damage lawn mower
or engine. For best results and to insure more
even grass distribution, do not mow when lawn is
excessively wet.
New grass, thick grass or wet grass may require a
narrower cut. Blade speeds should be adjusted to
the condition of the lawn.
The best mowing pattern is one that allows the
clippings to discharge towards the uncut part of
the lawn. This permits recutting of the clippings
to further pulverize them. When cutting high
weeds, discharge towards cut portion then recut
at right angles to first direction.
For best results, cut off one-third or less of the
total length of the grass. Lawn should be cut in
the fall as long as there is growth.
ADJUSTMENTS
CAUTION
A
Do not at any time make any adjust
ment to lawn mower without first
stopping engine and disconnecting
spark plug wire.
CONTROL ROD ADJUSTMENT
To adjust the control rod, remove the lockout lever
from the lockout bracket. Then refer to Control
Rod Installation on page 6.
HANDLE ADJUSTMENT
The handle may be adjusted to five different posi
tions. To adjust, remove the nut and bolt on the
lower handle support. Reassemble in desired
hole. See figure 12. When the handle height is
changed, it is necessary to readjust the control
rod.
IMPORTANT
If you strike a foreign object, stop
the engine. Remove wire from spark
plug, thoroughly inspect the mower
for any damage, and repair the
damage before restarting and
operating the mower.
USING YOUR ROTARY MOWER
For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings. If
wet grass must be cut, reduce walking speed to
help distribute the clippings more effectively.
Lowest
Position
FIGURE 12.
Page 9
CUTTING HEIGHT
The mower can be adjusted to four different cut
ting heights. Cutting height adjustment is made
by removing and moving axie bolts to the desired
positions. Ail axle bolts must be mounted in the
same relative position to the deck. When wheels
are mounted to the deck, the bellevMIe washers
must be assembled with the cupped side towards
the deck. This is necessary to prevent the axle
bolts from loosening. When assembling the rear
wheel, bellevMIe washers are placed against the
threaded hole in the frame. See figure 13.
i. t
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), disengage all
clutches and blades. Keep clear of
all moving parts and be careful of
heated surfaces and muffler.
CARBURETOR ADJUSTMENTS (See Figure 15)
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Initial Adjustment:
Turn needle valve clockwise to close it. Then open
2 turns. This initial adjustment will permit the
engine to be started and warmed up before mak
ing final adjustment.
Beileviile
Washer
Axle Bolt
FIGURE 13.
THROTTLE
If adjustment becomes necessary, the throttle
control wire assembly can be reset as follows:
1. Loosen, but do not remove, screw securing
throttle control wire assembly at engine. See
figure 14.
2. Move throttle control lever on handle to
“CHOKE” position.
3. Move lever, to which control wire is fastened
at engine, to full open position. Retighten
screw to secure throttle control wire
assembly.
Final Adjustment:
With engine running at normal operating speed
(approximately 3000 RPM without load), turn nee
dle valve clockwise until engine starts to lose
speed (lean mixture). Then slowly turn needle
valve counterclockwise past the point of
smoothest operation, until engine just begins to
run unevenly. This mixture will give best perform
ance under load.
To check adjustment, move engine control from
SLOW to FAST speed. If engine tends to stall or
die out, it usually indicates that the mixture is
slightly lean. It may be necessary to open the nee
dle valve slightly to provide a richer mixture. This
richer mixture may cause a slight unevenness in
idling.
FIGURE 14. FIGUREIS.
Page 10
LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark plug wire before cleaning,
lubricating or doing any kind of
work on lawn mower.
Wheels—Unit is provided with ball bearing
wheels. Lubricate at least once a season with light
oil. To lubricate the rear wheels, remove the oil
caps and add several drops of oil. See figure 16.
Also, if the wheels are removed for any reason,
lubricate the surface of the axle bolt and the inner
surface of the wheel with light oil. A 4 oz. plastic
bottle of light oil lubricant is available. Order part
number 737-0170. Engine oil may also be used.
Blade Spindle Assembly—The blade spindle
assembly is equipped with a grease fitting. Use
grass discharge chute for access to the fitting
located under the deck. Use multi-purpose grease.
Lubricate PRIOR to initial use and every 25 hours
thereafter.
MAINTENANCE
CUTTING BLADE
A. Removal for Sharpening or Replacement
\ WARNING J
Be sure to disconnect and ground
the spark plug wire before working
on the cutting blade to prevent
accidental engine starting.
FIGURE 16.
Protective Shield—The pivot points on the protec
tive shield should be lubricated periodically with
light oil to prevent any rust or binding.
Chute Deflector—The torsion spring and pivot
point should be lubricated periodically with light
oil to prevent any rust or binding. Deflector must
work freely.
Engine—Follow engine manual for lubrication in
structions. Check oil level before each use.
Throttle—Periodically lubricate throttle control
lever and throttle wire assembly with a few drops
of light oil for ease of operation.
Friction point between idler bracket assembly
(Ref. No. 9 on page 15) and deck should be
greased once each season with a multi-purpose
grease.
1. Remove the large bolt and lock washer which
holds the blade and adapter to the blade spin
dle.
2. Remove the blade and adapter from the spin
dle. Be careful not to lose the key on the spin
dle.
3. If the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and
nuts which hold the blade to the adapter.
B. Sharpening
Remove the cutting blade by following the direc
tions of the preceding section.
When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge receives an equal amount
of grinding to prevent an unbalanced blade. An un
balanced blade will cause excessive vibration
when rotating at high speeds, may cause damage
to the mower and could break, causing injury.
The blade can be tested for balance by balancing
it on a round shaft screwdriver. Remove metal
from the heavy side until it balances evenly.
NOTE
It is recommended that the blade
always be removed from the adapter
for the best test of balance.
10
Page 11
C. Reassembly
Before reassembling the blade and the blade
adapter to the unit, lubricate the spindle and the
inner surface of the blade adapter with light oil.
Lubricating the bolt holes, bolts and inner surface
of the nuts with light oil is also recommended. A 4
oz. plastic bottle of light oil lubricant is available.
Order part number 737-0170. Engine oil may also
be used.
When replacing the blade, be sure to install the
blade with the side of the blade marked “Bottom”
(or with part number) facing the ground when the
mower is in the operating position. Make certain
key is in place on the blade spindle.
Blade Mounting Torque
3/8" Dia. Bolt 375 in. lb. min., 450 in. lb. max.

To insure safe operation of your unit, ALL nuts
and bolts must be checked periodically for correct
tightness.
DECK
The underside of mower deck should be cleaned
after each period of use as grass clippings, leaves,
dirt and other matter will accumulate. This ac
cumulation of grass clippings, etc., is undesirable
as it will invite rust and corrosion and may cause
an uneven discharge of grass clippings at the next
cutting.
The deck may be cleaned by tilting the mower for
ward or on its side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose.
CAUTION
A
Do not direct the stream of water at
a hot engine as damage to the
engine may result.
AIR CLEANER
Clean air cleaner and re-oil element every 25 hours
under normal conditions. Clean every few hours
under extremely dusty conditions. Poor engine
performance and flooding usually indicates that
the air cleaner should be serviced. See figure 17.
To service air cleaner:
1. Remove screw.
2. Remove air cleaner carefully to prevent dirt
from entering carburetor.
3. Take air cleaner apart and clean.
a. WASH foam element in kerosene or a liq
uid detergent and water to remove dirt.
b. DRY foam completeiy by wrapping and
squeezing in a cloth.
c. SOAK foam with engine oil. Squeeze to
distribute and remove excess oil.
4. Reassemble parts and fasten to carburetor.
