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 6 mm to 13 mm (1/4” to 1/2”) 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.
GB–10
1. Clean around fuel tank cap and remove cap from
tank (Fig. 7). Do not fill tank full. Using
unleaded gasoline, fill fuel tank to within 6 to 13
mm (1/4” to 1/2”) from top of tank, not into
filler neck.
2. Install fuel tank cap and wipe up any spilled
gasoline.
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: Do not mix oil with the
gasoline. Never use methanol
, gasoline
containing methanol, gasohol containing
more than 10% ethanol, premium gasoline, or
white gas because engine fuel system damage
could result.
Before Starting
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.

Operation
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
4
1711
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.
General Tips
Follow these instructions whether cutting grass or
leaves for the best cutting results and lawn
appearance:
• Maintain a sharp blade
season. Periodically file down nicks on blade.
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 also may be slippery to walk
on and could cause you to slip and fall.
throughout the cutting
Cutting Grass
• Grass grows at different rates at different times
of the year. In the heat of the summer, it is
generally best to cut grass at the C, D or E
height-of-cut settings. Only about 1/3 of the
grass blade should be cut off. Cutting below the
C 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:
GB–15
Operation
• 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.
• Mow across the marginal areas a second time.
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.
• 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.
GB–16
Maintenance
POTENTIAL HAZARD
• If you leave the wire on the spark plug, someone could start the engine.
WHAT CAN HAPPEN
• Accidental starting of engine could seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
• Pull wire off spark plug before you do any maintenance. Also push wire aside so it
does not accidentally contact spark plug.
Servicing Air Cleaner
Normally, replace air cleaner after every 25 operating
hours. More frequent replacing is required when
mower is operated in dusty or dirty conditions. See
your Authorized Toro Service Dealer for replacement
parts.

Adjusting Wheel Traction Drive
(self-propelled model only)
If mower does not self-propel or has a tendency to
creep forward when drive is not engaged, an
adjustment to the wheel traction control cable is
necessary.
1. Stop the engine.
2. Turn knob clockwise if mower has tendency to
creep when drive is not engaged. Turn knob
counterclockwise if mower does not propel when
drive is engaged.

Note: Determine left and right sides of
mower by standing in the operator’s
position.
Adjustment is correct when:
• mower does not creep forward when traction is
disengaged
• self-propelled control bar is at a comfortable
operating distance from the handle for operator’s
hand when disengaging and engaging the
self-propelled drive
Note: Do not overadjust cable. Cable should
be just tight enough to make wheels
turn when self-propelled control bar is
at a distance from the handle that is
comfortable for operator’s hand.
Overadjusting may require excessive
operator effort to engage or disengage
self-propelled drive.
If you need help, see your Authorized Toro Service
Dealer.

4. INSPECTING BLADE—Carefully examine
blade for sharpness and wear, especially where
flat and curved parts meet (Fig. 25A). Since sand
and abrasive material can wear away the metal
that connects the flat and curved parts of the
blade, check blade before using the mower. If a
slot or wear is noticed, (Fig. 25B & C), replace
blade. Refer to step 5.
1973
POTENTIAL HAZARD
• Gasoline is extremely flammable, highly
explosive and under certain conditions can
cause personal injury or property damage.
WHAT CAN HAPPEN
• Tipping mower may cause fuel leakage
from carburetor or fuel tank.
HOW TO AVOID THE HAZARD
• Avoid fuel spills by running engine dry or
remove gas with hand pump, never siphon.
3. Tip mower on its left side (Fig. 24). Avoid
rotating the blade because starting problems may
result.

Maintenance
Note: For best performance, install new blade
before cutting season begins. During
the year, file down small nicks to
maintain the cutting edge.
POTENTIAL HAZARD
• A worn or damaged blade could break and
a piece of blade could be thrown into
operator’s or bystander’s area.
WHAT CAN HAPPEN
• A thrown piece of blade could cause serious
personal injury or death to operator or
bystanders.
HOW TO AVOID THE HAZARD
• Inspect blade periodically for wear or
damage.
• Replace a worn or damaged blade.

1. Sharpen a t this angle only
7. Install sharp, balanced TORO blade, blade
stiffener, lockwasher and blade bolt. Sail part of
blade must point toward top of mower housing
to ensure correct installation. Tighten the blade
bolt to 68 Nm (50 ft–lb).
POTENTIAL HAZARD
• When sharpening blade, pieces of blade
could be accidentally thrown.
5. REMOVING BLADE—Grasp end of blade
using a rag or thickly padded glove. Remove
blade bolt, lockwasher, blade and blade stiffener
(Fig. 24).
6. SHARPENING BLADE—Using a file, sharpen
top side of blade and maintain original cutting
angle (Fig. 26). The blade will remain balanced
if same amount of material is removed from both
cutting edges.
IMPORTANT: Check balance of blade by
putting it on a blade balancer. An inexpensive
balancer can be purchased at a hardware
store. A balanced blade stays in a horizontal
position and an unbalanced blade settles to
the heavy side. If blade is not balanced, file
more metal off cutting edge on heavy end of
blade.
WHAT CAN HAPPEN
• Thrown objects can cause serious eye
injury.
HOW TO AVOID THE HAZARD
• Wear proper eye protection when
sharpening blade.
POTENTIAL HAZARD
• Operating mower without stiffener in place
could cause blade to flex, bend or break.
WHAT CAN HAPPEN
• A broken blade could cause serious injury
or death to operator or bystanders.
HOW TO AVOID THE HAZARD
• Do not operate mower without stiffener.
Lubrication
GB–22
After every 25 operating hours or when season ends,
front and rear wheels must be lubricated.
Maintenance
1. Apply one or two drops of light oil on inside and
outside of all wheel bolts. Spin wheels to
distribute oil into bushings. Wipe up excess oil.
2. SELF-PROPELLED MODEL–Drain gasoline;
refer to Draining Gasoline, page 17.
3. Set mower to highest height-of-cut setting (E).
4. Tip mower on its left side. Wipe grease fittings
with clean rag (Fig. 27). Install grease gun onto
fitting and gently apply one or two pumps of #2
Multi-Purpose Lithium Base Grease.
Underside of Mower Housing
Keep underside of mower housing clean. Be
especially careful to keep kickers free of debris
(Fig. 29).
Washing Method
1. Position mower on a flat surface near a garden
hose.
2. Start the engine.
3. Hold the running garden hose at handle level and
direct water to flow on ground just in front of
right rear tire (Fig. 28). The rotating blade will
draw water under the housing and wash out
clippings. Let the water run for a few minutes or
until you no longer see clippings being washed
out from under housing.

Storage
1. For long term storage, it is recommended that
gasoline be drained from fuel tank or use a fuel
additive before storing. To drain gasoline, refer
to Draining Gasoline. After fuel is drained, start
engine and let it idle until all fuel is consumed
and engine stops. If gasoline is not drained,
gum–like varnish deposits will form and cause
poor engine operation or even starting problems.
Fuel can be left in gas tank only if a fuel
additive, such as Toro’s Stabilizer/Conditioner, is
added to gasoline and run through engine before
storing. 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. Use fuel additive in recommended
quantities as specified on container.
Under normal conditions, fuel additives remain
effective in fuel for 6-8 months.
2. Drain oil: refer to Changing Crankcase Oil. After
oil is drained, do not fill crankcase with oil until
the following steps (3–10) are completed.
9. Lubricate the wheels; refer to Lubrication
section.
10. Touch up all rusted or chipped paint surfaces.
Toro Re-Kote paint is available from an
Authorized TORO Service Dealer.
11. Fill crankcase with oil; refer to Fill Crankcase
With Oil.
12. Store mower in a clean, dry place. Cover mower
to keep it clean and protected.
3. Remove spark plug and pour 30 ml
(2 tablespoons) of SAE 30 oil into hole in
cylinder. Pull starter rope slowly to coat inside of
cylinder. Install spark plug and tighten to 20 Nm
(15 ft–lb). DO NOT INSTALL WIRE ON
SPARK PLUG.
4. Clean mower housing; refer to Cleaning Mower
Housing.
5. Check condition of blade; refer to
Inspecting/Removing/Sharpening Blade.
6. Tighten all nuts, bolts, and screws.
7. Clean dirt, chaff, grass clippings, and grime from
external parts of the engine, shrouding, and top
of mower housing.
8. Clean air cleaner; refer to Servicing Air Cleaner.
