the controls and the proper use of the equipment.
2. Never allow children or people unfamiliar with
these instructions to use the lawnmower. Local regu-
lations may restrict the age of the operator.
3. Never mow while people, especially children, or
pets are nearby.
4. Keep in mind that the operator or user is respon-
sible for accidents or hazards occurring to other
people or their property.
PREPARATION
1. While mowing, always wear substantial footwear
and long trousers. Do not operate the equipment
when barefoot or wearing open sandals.
2. Thoroughly inspect the area where the equip-
ment is to be used and remove all objects which
may be thrown by the machine.
3. WARNING — Petrol is highly flammable.
e Store fuel in containers specifically designed for
this purpose.
e Refuel outdoors only and do not smoke while
refuelling.
e Add fuel before starting the engine. Never re-
move the cap of the fuel tank or add petrol while the
engine is running or when the engine is hot.
e If petrol is spilled, do not attempt to start the en-
gine but move the machine away from the area of
spillage and avoid creating any source of ignition
until petrol vapors have dissipated.
e Replace all fuel tanks and container caps se-
curely.
4. Replace faulty silencers.
5. Before using, always visually inspect to see that
the blades, blade bolts and cutter assembly are not
worn or damaged. Replace worn or damaged blades
and bolts in sets to preserve balance.
6. On multi-bladed machines, take care as rotating
one blade can cause other blades to rotate.
OPERATION
1. Do not operate the engine in a confined space
where dangerous carbon monoxide fumes can col-
lect.
2. Mow only in daylight or in good artificial light.
3. Avoid operating the equipment in wet grass,
where feasible.

MIX GASOLINE AND OIL—50:1 RATIO
1. APPROVED OIlL—For simplicity and best engine
performance, mix the contents of one bottle of Toro
50:1 Two-— Cycle Oil with two gallons of fresh, un-
leaded regular gasoline. Leaded regular gasoline
may be used if unleaded regular is not available.
Toro Two—Cycle Oil is specially formulated to pro-
vide superior lubrication, make starting easy, and
prolong engine life. If Toro Two—Cycle Oil is not
available, mix two gallons of gasoline and 5.2
ounces of another high grade two—cycle oil that has
the NMMA or BIA—TCW certification printed on the
label.
Toro also recommends that Toro Stabilizer/Condition-
er 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: YOU CAN ALSO USE TORO "EASY—
MIX” TWO—CYCLE OIL (3.2 OUNCE BOTTLE MIXED
ONE PER GALLON OF GASOLINE) IN THIS TORO
TWO—CYCLE ENGINE.
NEVER USE AUTOMOTIVE OIL (i.e. SAE 30, 10W30
etc.), TWO—CYCLE OIL THAT IS NOT CERTIFIED
NMMA/BIA—TCW, OR THE WRONG MIX RATIO BE-
CAUSE THE ENGINE CAN BE DAMAGED, AND IT
WOULD NOT BE COVERED BY THE TORO WAR-
RANTY.
2. Mixing Gasoline and Oil-—Pour correct amount of
gasoline into an approved gasoline container and
add the correct amount of two—cycle oil. Install cap
on gasoline container and shake the container to mix
oil and gas thoroughly. Remove cap and add re-
maining amount of gasoline.
NOTE: Do not mix gasoline and oil in the product
fuel tank. Oil that is at room temperature mixes easi-
er and more thoroughly than cold oil.
IMPORTANT: NEVER USE METHANOL, GASO-
LINE CONTAINING METHANOL, GASOHOL. CON-
TAINING MORE THAN 10% ETHANOL, PREMIUM
GASOLINE, OR WHITE GAS BECAUSE ENGINE
FUEL SYSTEM DAMAGE COULD RESULT.
DO NOT USE FUEL ADDITIVES OTHER THAN
THOSE MANUFACTURED FOR FUEL STABILIZA-
TION DURING STORAGE SUCH AS TORO’S STA-
BILIZER/CONDITIONER OR A SIMILAR PROD-
UCT. TORO'S STABILIZER/CONDITIONER IS A
PETROLEUM DISTILLATE BASED STABILIZER/
CONDITIONER. TORO DOES NOT RECOMMEND
STABILIZERS WITH AN ALCOHOL BASE SUCH
AS ETHANOL, METHANOL OR ISOPROPYL. STA-

RECYCLER® MOWER TIPS
RECYCLER® MOWER FEATURES
The Toro Recycler® mower has a new and complete-
ly different cutting concept that leaves your lawn with
a bagged look without bagging clippings.
Your Recycler® mower is equipped with special parts
Which increase your mower's ability to cut and recut
grass clippings, leaves, and other yard debris into
tiny particles and inject them down into the grass.
These parts are:
A. A special blade and blade stiffener
B. Three special “kicker plates” positioned on the
underside of the mower deck in strategic positions
(Fig. 9)

ging or optional side discharge operations of the
mower.
ÁN WARNING
e Operating mower without stiffener in place
could cause blade to flex, bend or break.
e A broken blade could cause serious injury or
death to operator or bystanders.
e Do not operate mower without stiffener.
The plug, however, is a removable part, just as the
grass bag and optional side discharge chute are re-
movable parts. You cannot use the plug in combina-
tion with either the grass bag or the side discharge
chute.
It is possible to mow without using the plug by clos-
ing the discharge tunnel door. However, your lawn
appearance will be much more satisfactory if you
use the plug as it has an additional kicker (Fig. 10)
that helps drive the clippings down into the grass.
dA WARNING

C. A special plug which locks into the mower's dis-
charge tunnel (a fourth kicker is on the plug) (Fig.

KICKER PLUG
Figure 10
The blade and three kicker plates are permanent
parts of your mower. The blade should be removed
only for sharpening or replacement. The kickers
should never be removed, unless they need to be
replaced. They do not interfere with the normal bag-
UK—10
Grass clippings and other debris can be
thrown from an open discharge tunnel with
enough force to cause personal injury. Never
start or operate the mower unless one of the
following is true:
1. The discharge tunnel plug is locked secure-
ly in discharge tunnel.
2. The grass bag is locked in place.
3. The optional side discharge chute is locked
in place.
4. The discharge tunnel door is locked
closed.
& WARNING
Wet grass can cause you to slip and contact
blade. Blade contact can seriously injure you.
Mow only in dry conditions.
TIPS FOR CUTTING GRASS
CLIPPINGS
Even with the Recycler® mower, you may encoun-
ter conditions where it is not possible to hide all of
the finely cut clippings or leaves all of the time down
in the grass. Follow these instructions for the best
cutting results and lawn appearance:
e Maintain a sharp blade throughout the cutting
season. Periodically file down nicks on blade.
RECYCLER” MOWER TIPS
e Clean any residue from the underside of mower
housing, kickers, and plug after each use. See
Cleaning Mower Housing, Discharge Tunnel, Belt
Cover and Plug, page 17.
e When cutting grass over 6” tall, you may want to
cut the lawn twice to hide clippings down in the
grass.
e |n 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. Cutting
below the C setting is not recommended unless
grass is sparse or it is late fall when grass growth
begins to slow down. If long grass must be cut, you
may need to use a higher height—of—cut setting and
a slower walking speed; then recut the grass at a
more normal setting. If grass is too long and leaves
clumps on top of lawn, mower may plug and cause
engine to stall.
e 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:
e Sharpen the blade.
Walk at a slower pace while mowing.
Raise the height-of-cut setting on your mower,
Cut your grass more frequently.
Overlap cutting swaths instead of cutting a full
swath with each pass.
e Mow across the marginal areas a second time.
e 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)
TIPS FOR CUTTING LEAVES
You can cut up leaves in the fail instead of bagging.
If you decide to bag, the Recycler® mower reduces
the number of leaf bags you will need by finely chop-
ping up the leaves before they are bagged. Some
leaf particles will be injected back down into the soil.
When spring arrives, the leaf particles will have de-
composed and returned valuable nutrients to the
soil.
e Ensure leaves are dry.
e 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.
e For light leaf coverage, position all wheels at the
same height-of-cut setting.
e |[f there are more than 5” of leaves on lawn, set
the front wheels one or two notches higher than the
rear wheels. This makes it easier to feed leaves un-
der mower deck.
e Walk at a slower mowing speed if leaves are not
being cut up finely enough to be hidden down in the
grass.
e 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.

4. INSPECTING BLADE—Carefully examine blade
for sharpness and wear, especially where flat and
curved parts meet (Fig. 26A). Since sand and abra-
sive 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. 26B & C), replace blade. Refer to step 5.
Note: For best performance, install new blade before
cutting season begins. During the year, file down
small nicks to maintain the cutting edge.
£\ CAUTION
If blade is allowed to wear, a slot may form
near the sail. Eventually a piece of blade may
break off resulting in serious injury to yourself
or a bystander.

6. SHARPENING BLADE—Using a file, sharpen top
side of blade and maintain original cutting angle
(Fig. 27). The blade will remain balanced if same
amount of material is removed from both cutting
edges.
SHARPEN AT
THIS ANGLE ONLY

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 unbal-
anced blade settles to the heavy side. If blade is
not balanced, file more metal off cutting edge on
heavy end of blade.
7. Install sharp, balanced blade, blade accelerator,
lockwasher and blade bolt. Sail part of blade must
point toward top of mower housing to ensure correct
installation. Tighten blade bolt to 50 ft—Ib (68 N.m).
ÁN WARNING
e Operating mower without accelerator in place
could cause blade to flex, bend or break.
e A broken blade could cause serious injury or
death to operator or bystanders.
e Do not operate mower without accelerator.
MAINTENANCE
LUBRICATION
After every 25 operating hours or when season ends,
pivot arms must be lubricated.
1. Move rear wheel height—of-cut levers to center
setting. Wipe grease fittings with clean rag (Fig. 28).
Install grease gun onto fitting and gently apply 2 or 3
pumps of #2 Multi—Purpose Lithium Base Grease.
Excessive pressure may damage seals.

between wheel hub and pivot arm.
CLEANING MOWER HOUSING,
DISCHARGE TUNNEL, BELT COVER AND
PLUG
To ensure best performance, the discharge tunnel
plug must be cleaned after each use. When grass is
thick and lush, clippings may collect on and around
the plug; this may make plug removal difficult. After
each use, remove plug from discharge tunnel and
clean off all debris.
UK--17
MAINTENANCE
Keep underside of mower housing clean. Be espe-
cially careful to keep kickers on underside of mower
housing free of debris (Fig. 31).
Always be sure that discharge tunnel door locks
closed when handle is released. If debris prevents
discharge door from locking closed, clean inside of
discharge tunnel and door thoroughly.

PREPARING MOWER FOR STORAGE
1. For long term storage, either drain gasoline from
fuel tank or add a fuel additive to the gasoline. 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, even starting prob-
lems.
Fuel can be left in gas tank only if a fuel stabilizer,
such as Toro's Stabilizer/Conditioner, is added to
gasoline before storing. Toro's Stabilizer/Conditioner
is a petroleum distillate based stabilizer/conditioner.
Toro does not recommend stabilizers with an alcohol
base, such as ethanol, methanol or isopropyl. Use
fuel stabilizer in recommended quantities as speci-
fied on container.
Under normal conditions, fuel stabilizers remain ef-
fective in fuel for 6—8 months.
2. Remove spark plug and pour 2 teaspoons of
Toro Two~Cycle Qil into hole in cylinder. Pull starter
rope slowly to coat inside of cylinder. Install spark
plug and tighten to 10 ft—Ib (13.6 N-m). DO NOT
REINSTALL WIRE ON SPARK PLUG.
3. Clean underside of housing: refer to Cleaning
Mower Housing, Discharge Tunnel, Belt Cover and
Plug.
4. Check condition of blade: refer to Inspecting/Re-
moving/Sharpening Blade.
5. Tighten all nuts, bolts, and screws.
6. Clean dirt and chaff from cylinder, cylinder head
fins, and blower housing. Also remove grass clip-
pings, dirt, and grime from external parts of the en-
gine, shrouding, and top of mower housing.
7. Clean air cleaner: refer to Servicing Air Cleaner.
8. Lubricate the pivot arms: refer to Lubrication.
9. Touch up all rusted or chipped paint surfaces.
Toro Re—Kote paint is available from an Authorized
TORO Service Dealer.
10. Store mower in a clean, dry place, out of the
reach of children. Cover mower to keep it clean and
protected.
