ual carefully. Be thoroughly familiar v/ith the con
trols and the proper use of the equipment.
2. Never allov/ children to operate a pov/er mower.
3. Keep the area of operation clear of all persons,
particularly small children and pets.
PREPARATION
1. Thoroughly inspect the area where the equipment
is to be used and remove all stones, sticks, wire,
bones and other foreign objects.
2. Do not operate equipment when- barefoot or
wearing open sandals. Always wear substantial
footwear.
3. Check the fuel before starting the engine. Do not
fill the gasoline tank indoors, when the engine is
running, or while the engine is still hot. Wipe off
any spilled gasoline before starting the engine.
4. Disengage the self-propelled mechanism or drive
clutch on units so equipped before starting the en
gine (motor).
5. Never attempt to make a wheel adjustment while
the engine (motor) is running.
6. Mow only in daylight or in good artificial light.
7. Never operate the equipment in wet grass. Al
ways be sure of your footing; keep a firm hold on
the handle and walk, never run.
5. If the equipment should start to vibrate abnormal
ly, stop the engine (motor) and check immediately
for the cause. Vibration is generally a warning of
trouble.
6. Stop the engine (motor) whenever you leave the
equipment, before cleaning the mower housing,
and when making any repairs or inspections.
7. When cleaning, repairing or inspecting, make cer
tain 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. Do not run the engine indoors.
9. Shut the engine (motor) off and wait until the
blade comes to a complete stop before removing
the grass catcher or unclogging chute.
10. Mow across the face of slopes, never up-anddown. Exercise extreme caution when changing
direction on slopes. Do not mow excessively steep
slopes.
11. Always disconnect electric mowers (line operated)
before cleaning, repairing or adjusting.
12. Never operate mower without proper guards,
plates or other safety protective devices in place.
13. Keep washout ports and other mower-housing
service openings closed when mowing.
MAINTENANCE AND STORAGE
OPERATION
1. Do not change the engine governor settings or
overspeed the engine.
2. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at all
times.
3. Stop the blade(s) when crossing gravel drive,
walks or roads.
4. After striking a foreign object, stop the engine
(motor), remove the wire from spark plug, thor
oughly inspect the mower for any damage, and
repair the damaoe before restarting and operat
ing the mower.
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 condition.
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.
5. Check the grass catcher bag frequently for wear
or deterioration. Replace with new bag for safety
protection.

ASSEMBLY
OPERATION
Your new mower is shipped preassembled with the
exception of the handle.
1. Remove lawn mower and all parts from the carton.
Make certain that all loose parts and literature have
been removed before the carton is discarded.
2. Extend throttle control assembly which is attached
to rear of mower and place on the floor. CAUTION:
Do not bend or kink control wire.
3. a. Snap lower handle into position on two studs
which extend from either side on the rear of the
deck in front of the rear wheels.
NOTE
It may be necessary to bend the lower
handle in. This will insure a tight fit
when assembled over weld studs on
your unit.
b. Assemble the two upper handle parts with cap
screws and locknuts provided in parts bag. The
yellow cap screw should be used to attach throt
tle control assembly to upper handle. Do not
tighten nuts.
c. Attach upper handle assembly to lower handle
with cap screws and locknuts. Tighten all nuts.
d. Secure control wire to lower handle with cable
clips.
4. Check ALL nuts and bolts for correct tightness.
NOTE
For shipping purposes your mower is
set with the wheels in a low cutting
height position. For best results raise
the cutting position until it is deter
mined which height is best for your
lawn. See adjustments.
1. Service engine with gas and oil. See Engine Manual
packed with lawn mower for complete instructions
for the care and maintenance of engine. Read Di
rections carefully.
2. When ready to start engine, place throttle control
lever, on handle, in "START" position and start en
gine in accordance with instructions in Engine Man
ual. After engine starts, move throttle control lever,
on handle, to desired engine speed. The engine is
stopped by placing control lever on handle in the
"STOP" position.
3. 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 ex
cessively wet.
ADJUSTMENTS
CAUTION
CAUTION
Please note that the chute deflector on
your mower is in an upright position. It
is held in that position by a shipping
block. This block is used for shipping
purposes only. It must be removed and
discarded before your mower is put
into operation.
Chute Deflector
Shipping Block to be Removed
Do not at any time make any adjust
ment to lawn mower without first stop
ping engine and disconnecting spark
plug wire.
EASY CUTTING HEIGHT (OPTIONAL)
An adjusting plate and thumb lever at each wheel po
sition provides cutting height adjustment. Each adjust
ing plate has five holes. Height of cut will be changed
when the thumb lever is moved from one hole to an
other. Simply depress thumb lever towards wheel and
move wheel and lever assembly to desired position.
All wheels must be positioned in relative height of
cut positions.
STANDARD CUTTING HEIGHT
Adjustment may be made by removing and moving
wheel studs to desired position. Cutting heights will
be raised as wheel studs are moved to a lower hole
and lowered as wheel studs are moved to a higher hole
in the deck. All wheel studs must be mounted in a
relative position to the deck.
Page 4
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.
2. Move throttle control lever on handle to "FAST"
position.
When sharpening 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 unbalanced blade will
cause excessive vibration when rotating at high speeds
and may cause damage to the mower.
Upon reassembly, make certain all parts are assembled
properly and tightened securely.
NOTE
3. Move lever, to which control wire is fastened at
engine, to full open position and retighten screw
to secure throttle control wire assembly.
LUBRICATION
IMPORTANT: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any
kind of work on lawn mower.
Wheels —• Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
Optional Ball Bearing Wheels — Wheel bearings are
ball bearings and require lubrication at least once a
season with a light oil.
Throttle — Periodically lubricate throttle control lever
and throttle wire assembly with a few drops of light
oil (SAE No. 10 or 20) for ease of operation.
Protective Shield — The pivot points on the protective
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 pre
vent any rust or binding. Deflector must work freely.
CHANGE OIL (Oil Sump)
Change oil after 5 hours
of operation while en
gine is warm. There
after, change oil every
25 hours of operation
while engine is warm.
Periodically check ALL nuts and bolts
for correct tightness to insure sofe oper
ation of your unit.
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 forward
or on its side and scraping clean with a suitable tool
or by washing with a stream of water from a garden
hose.
CAUTION: Do not direct the stream of water at a hot
engine as damage to the engine may result.
STORAGE — The following steps should be taken to
prepare lawn mower for storage.
1. Clean and lubricate mower thoroughly as described
in the preceding instructions.
2. Refer to Engine Manual for correct engine storage
instructions.
3. Coat mower's cutting blade with chassis grease to
prevent rusting.
4. Place blocks under deck to raise tires clear of floor.
5. Store mower in a dry, clean area.
USING YOUR ROTARY MOWER
MAINTENANCE
CUTTING BLADE
The blade may easily be removed for grinding or
replacement as follows:
1. Remove bolt and lock washer holding blade and
blade adapter to engine crankshaft.
2. Remove blade and blade adapter from engine
crankshaft.
3. Remove two bolts, lock washers and nuts holding
blade to blade adapter (if necessary).
For the best results do not cut wet grass because it
tends to stick to the underside of the mower, thus pre
venting proper discharge of grass clippings. If wet
grass must be cut, reduce walking speed to help dis
tribute the clippings more effectively.
New grass should be treated as wet grass, otherwise
a normal walking speed is about the right pace for
efficient mowing.
The best mowing pattern is one that allows the clip
pings to discharge towards the uncut part of the lawn.
This permits recutting of the clippings to further pul
verize them. When cutting high weeds, discharge to
wards cut portion then recut at right angles to first di
rection.
Lawn should be cut in the fall as long as there is
growth.

NOTE
The manufacturer DOES NOT recommend the use of
any accessory on this Rotary Mower other than those
manufactured by MTD Products Inc.
GRASS CATCHER Model No. 194-003A is available as optional
equipment for the mowers shown in this manual.
WARNING:
1. The mower should not be operated without the entire grass catcher
or chute deflector in place.
2. The mower should not be operated without the protective shield on
the rear of the deck in place.
NOTE:
Under normal usage bag material is subject to wear and should be
checked periodically. Be sure any replacement bag complies with the
mower manufacturer's recommendations.
For replacement bags, use only factory authorized replacement bag No.
764-119.
^IMPORTANT
After striking a foreign object, stop the engine (motor), remove wire
from spark plug. Thoroughly inspect the mower for any damage, and
repair the damage before restarting and operating the mower.
