Assembly
Note: Determine left and right hand sides of
the unit by standing in the normal
operators position.
Handle
1. The mower is shipped from the factory with
filler between the upper and lower handle joints
to prevent shipping and assembly damage. Align
upper and lower handles and remove the filler
with a pliers.
2. The left handle knob is shipped from the factory
on the outside of the handle (Fig. 2). Remove the
left knob and bolt. Reinstall knob and bolt on
inside of handle (Fig. 3). Both handle knobs
should be positioned on the inside of the
handles. Tighten handle knobs.
3. Move handle latches slightly outward so they
will not be in the way when pivoting the handle
backward into the operating position (Fig. 3).
4. Pivot handle backward. Move handle latches
inward while snapping handle stud into center
hole of handle latch (Fig. 3). If a handle latch
does not fit tightly against the handle tube,
remove latch from handle stud, bend the latch
inward, and reattach to handle stud. Repeat as
necessary to ensure a tight fit between latch and
handle. Make sure handle knobs are securely
tightened.
Note: If handle height is not satisfactory,
adjust by placing handle stud into a
different hole.
5. Ensure control cables are to the rear and inside
of handles. Secure cables to handle with cable
ties (Fig. 3).
Starter Rope
Pull starter rope through rope guide on handle
(Fig. 4).
Before Starting
Oil
Fill crankcase with SAE 30 or 10W30 oil until oil
level reaches FULL mark on dipstick as shown in
(Fig. 5). The maximum crankcase capacity is 22
ounces (0.65 liters) of oil. Use any high quality
detergent oil having the American Petroleum Institute
(API) “service classification” — SF, SG, SH or SJ.
Before each use, ensure oil level is between FULL
and ADD marks on dipstick (Fig. 5). Add oil if level
is low.
1. Position mower on level surface and clean
around oil dipstick (Fig. 5).
2. Remove dipstick by rotating cap
counterclockwise 1/4 turn.
3. Wipe dipstick and insert it into filler neck.
Rotate cap clockwise 1/4 turn. Then remove
dipstick and check level of oil on side of dipstick
with FULL and ADD marks (Fig. 5). If level is
low, add only enough oil to raise level to FULL
mark on dipstick. DO NOT FILL ABOVE
FULL MARK BECAUSE ENGINE COULD
BE DAMAGED WHEN STARTED. POUR
OIL SLOWLY.
4. Insert dipstick into filler neck and rotate cap
clockwise 1/4 turn to lock.
Note: Check oil level each time mower is
used or after every 5 operating hours.
Initially, change oil after the first 5
hours of operation; thereafter, change
oil after every 50 hours of operation.
More frequent oil changes are required
in dusty or dirty conditions.
EN–7
Gasoline
POTENTIAL HAZARD
In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is cold.
Wipe up any gasoline that spills.
Do not fill the fuel tank completely full.
Add gasoline to the fuel tank until the level
is 1/4” to 1/2” (6 mm to 13 mm) below the
bottom of the filler neck. This empty space
in the tank allows gasoline to expand.
Never smoke when handling gasoline, and
stay away from an open flame or where
gasoline fumes may be ignited by a spark.
Store gasoline in an approved container
and keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
This engine is certified to operate on unleaded
gasoline. Toro strongly recommends the use of fresh,
clean, UNLEADED regular grade gasoline with an
octane rating of 85 or higher in Toro gasoline
powered products. Unleaded gasoline burns cleaner,
extends engine life, and promotes good starting by
reducing the build-up of combustion chamber
deposits. In countries other than U.S.A., leaded
gasoline may be used if it is commercially available
and unleaded is unavailable.
IMPORTANT: Do not mix oil with the gasoline.
Do not use gasoline that has been stored in an
approved container from one season to the next.
Toro also recommends that Toro
Stabilizer/Conditioner be used regularly in all Toro
gasoline powered products during operation and
storage seasons. Toro Stabilizer/Conditioner cleans
the engine during operation and prevents gum-like
varnish deposits from forming in the engine during
periods of storage.
IMPORTANT: Some fuels, called oxygenated or
reformulated gasolines, are gasolines blended with
alcohols or ethers. Excessive amounts of these
blends can damage the fuel system or cause
performance problems. Never use methanol
,
gasoline containing methanol, gasohol containing
more than 10% ethanol or white gas because
engine fuel system damage could result. If any
undesirable operating symptoms occur, use
gasoline with a lower percentage of alcohol or
ether.
Do not use fuel additives other than those
manufactured for fuel stabilization during storage
such as Toro’s Stabilizer/conditioner or a similar
product. Toro’s Stabilizer/conditioner is a
petroleum distillate based conditioner/stabilizer.
Toro does not recommend stabilizers with an
alcohol base such as ethanol, methanol or
isopropyl. Additives should not be used to try to
enhance the power or performance of machine.
1. Clean around fuel tank cap and remove cap from
tank (Fig. 6).
2. Using unleaded gasoline, fill fuel tank to within
1/4” to 1/2” (6 to 13 mm) from top of tank, not
into filler neck. Do not fill tank full.
3. Reinstall fuel tank cap and wipe up any spilled
gasoline.
4. Connect spark plug wire (if disconnected)
(Fig. 8).
Recycling Tips
General Tips
Follow these instructions whether cutting grass or
leaves for the best cutting results and lawn
appearance:
Maintain a sharp blade
throughout the cutting
season. Periodically file down nicks on blade.
EN–8
Only mow dry grass or leaves. Wet grass and
leaves tend to clump on yard and may cause
mower to plug or engine to stall. They may also
be slippery to walk on and could cause you to
slip and fall.
POTENTIAL HAZARD
Wet grass or leaves can cause you to slip
and contact blade.
WHAT CAN HAPPEN
Blade contact can seriously injure you.
HOW TO AVOID THE HAZARD
Mow only in dry conditions.
Set engine speed to fastest position. Maximum
horsepower provides best cutting results.
Clean clippings or leaves from underside of
mower deck after each mowing.
Keep engine in good running condition. Cutting
and recutting requires more horsepower.
Clean air filter more frequently. Cutting and
recutting stirs up more clippings and dust which
clogs the air filter and reduces engine
performance.
Cutting Grass
Grass grows at different rates at different times
of the year. In the heat of summer, it is generally
best to cut grass at the C, D or E height-of-cut
settings. Only about !/3 of the grass blade should
be cut off. Cutting below the C inch setting is
not recommended unless grass is sparse or it is
late fall when grass growth begins to slow down.
When cutting grass over six inches tall, you may
want to first mow using the highest height-of-cut
setting and a slower walking speed; then mow
again at a lower setting for best lawn appearance.
If grass is too long and leaves clumps on top of
lawn, mower may plug and cause engine to stall.
Alternate mowing direction. This helps disperse
clippings over lawn for even fertilization.
If the finished cut lawn appearance is unsatisfactory,
try one or more of the following:
Sharpen the blade.
Walk at a slower pace while mowing.
Raise the height-of-cut setting on your mower.
Cut grass more frequently.
Overlap cutting swaths instead of cutting a full
swath with each pass.
Set height-of-cut on front wheels one notch
lower than rear wheels. (example: set front
wheels at “C” setting and rear wheels at “D”
setting)
Cutting Leaves
When cutting is complete, always be sure that
50% of the lawn shows through the cut leaf
cover. This may require one or more passes over
the leaves.
For light leaf coverage, position all wheels at the
same height-of-cut setting.
If there are more than five inches of leaves on
lawn, set the front wheels one or two notches
higher than the rear wheels. This makes it easier
to feed leaves under mower deck.
Walk at a slower mowing speed if leaves are not
being cut up finely enough to be hidden down in
the grass.
If you cut up a lot of oak leaves, you might want
to add lime to your grass in the spring. Lime
reduces the acidity of oak leaves.

Operation
Controls
Throttle control, ground speed control, control bar
and recoil starter are on upper handle (Fig. 7).
Starting Engine
Note: The engine requires a warm-up period
of one minute to several minutes,
depending on the temperature.
1. Push spark plug wire onto spark plug (Fig. 8).
2. Move throttle control to
(FAST) position.
3. Push primer three (3) times (Fig. 6). Wait about
two (2) seconds between each push.
Note: Do not use primer to restart a warm
engine after a short shutdown.
However, cool weather may require
priming to be repeated.
4. Pull recoil starter out until slack in rope is taken
up. Then pull vigorously to start the engine.
Regulate throttle as desired between
(FAST)
and
(SLOW). Allow the engine to warm-up.
During warm-up, the equipment can be operated.
Stopping Engine
1. Release control bar to stop blade and traction
drive. Move ground speed control to “N”
(NEUTRAL). To stop engine, move throttle to
(OFF). Stay behind the handle until all
moving parts stop.
2. Pull wire off spark plug if mower will be
unattended or not used.
Self-propelled Drive
The mower has three ground speeds: number “1” is
slow, “2” is medium, and “3” is a fast walking pace.
1. Move ground speed control to desired setting.
2. Move control bar down to “A” and raise to “B”
to engage blade (Fig. 9).
3. Squeeze control bar against handle “C” to
engage traction drive (Fig. 9).
Ground speed varies, depending on space
between control bar and handle. To disengage
traction drive but keep blade engaged, gradually
release control bar to mid position (Fig. 9).
To self-propel with blade disengaged, simply
squeeze control bar against handle, eliminating
downward movement necessary for blade
engagement.
Note: Do not shift speeds while control bar is
squeezed against handle in the “C”
(drive) position (Fig. 9); the
transmission could be damaged. Move
control bar to the mid position when
changing ground speed.
Ground speed can be varied by increasing or
decreasing distance between control bar and handle.
Lower control bar to slow mower when making a turn
or if mower is moving too fast for you. If you lower
control bar too far, the mower will stop
self-propelling. Squeeze control bar closer to handle
to increase ground speed. When control bar is tight
against handle, mower will self-propel at maximum
ground speed. Move ground speed control to “N”
(NEUTRAL) when using the mower for trimming
and whenever leaving mower.
Pulling Mower Rearward
Your mower is equipped with free-wheeling clutches
which make it easier to pull the mower rearward. The
control bar must be lowered enough to disengage the
self-propelled drive and disengage the clutches before
pulling the mower rearward. The mower may need to
be pushed forward one inch or more after control bar
has been released to disengage the self-propelled
drive and disengage the clutches.
EN–10
For example, if you are approaching an object such as
a tree or bush from which you want to pull back the
mower, lower the control bar just enough to
disengage the traction drive when the mower is about
six inches away from the object. The momentum of
the mower should carry it forward at least one inch
which will disengage the clutches. Then you should
be able to easily pull the mower rearward.
The self-propelled cable should be properly adjusted
so that you can lower the control bar comfortably to
stop the traction drive without stopping the engine.
See Self-propelled Cable section in the Maintenance
chapter for cable adjustment information. If you need
help, see your Authorized Toro Service Dealer.
Adjusting Cutting Height
Height of cut can be adjusted to five settings
(Fig. 10). For normal cutting, set all four wheels in
the same position.
1. Stop engine and wait for all moving parts to
stop. Pull wire off spark plug (Fig. 8).
POTENTIAL HAZARD
Adjusting height-of-cut levers could bring
hands into contact with moving blade.
WHAT CAN HAPPEN
Contact with rotating blade can cause
serious injury.
HOW TO AVOID THE HAZARD
Stop engine and wait for all movement to
stop before adjusting cutting height.
Do not put fingers under housing when
adjusting height-of-cut.
2. For easier adjustment, lift housing up so wheel is
off ground. Do not place hands under deck
when lifting housing. Squeeze adjusting lever
toward wheel and move it to the desired setting
(Fig. 10). Ensure pin on adjusting lever engages
hole in bracket.
Note: Front wheels can be adjusted to 1/2
inch. Move adjusting lever past “A”
and release pin into slot in housing. It
is not recommended that the 1/2 inch
height-of-cut setting be used on a
regular basis.
Check Control Bar Operation
Check the control bar before each use to ensure the
Blade Brake Clutch (BBC) system is operating
properly.
A: Normal Control Bar Operation Test
1. With engine off, wheel mower onto a paved
surface in a non-windy area.
2. Put all four wheels in “E” height–of–cut position
(Fig. 10).
3. Put ground speed selector in “N” (neutral)
position.
4. Take a half sheet of newspaper and crumple it
into a ball small enough to go under deck
(approx. three inches in diameter) (Fig. 11).
5. Place ball of newspaper five inches in front of
mower (Fig. 11).
6. Start the engine.
7. Push control bar down to lowest position
(Fig. 12).
8. Lift control bar to the normal “blade engaged”
position (about one inch below the handle)
(Position A, Fig. 13). The “fan” noise indicates
that the mower blade is turning.
9. Release the control bar (Position B, Fig. 13). A
“bang” should be heard. The blade should stop
running in three seconds.
10. Immediately push the mower over the newspaper
ball.
11. Turn off the engine.
