SAFETY INSTRUCTIONS
This safety alert symbol
means CAUTION, WARN-
ING, or DANGER — “per-
sonal safety instruction”.
Read and understand the
instruction, because it has
to do with safety. Failure
to comply with the in-
struction may result in personal injury.
The following “Instructions for Safe Tilling” are
suggested by The Toro Company. Failure to oper-
ate the tiller in accordance with these Safety In-
structions MAY RESULTIN PERSONAL INJURY.
BEFORE OPERATING
1. Read and understand the contents of this
manual before starting and operating the tiller. Be-
come familiar with all controls and know how to
stop tiller quickly. NEVER ALLOW CHILDREN
TO OPERATE TILLER.
2. Keep everyone, especially children and pets,
away from the area of operation. Remove glass,
metal objects, sticks, stones, wire and any other de-
bris that might get caught in or possibly be thrown
by the tines.
3. Keep all shields and safety devices in place. If
shield, safety device or decal is defective or dam-
aged, repair or replace it before operation is com-
menced. Also tighten any loose nuts, bolts and
screws.
4. Wear long pants and substantial shoes while us-
ing the tiller. Do not operate tiller while barefoot,
wearing sandals, tennis shoes, sneakers or shorts.
5. Fill fuel tank with gasoline before starting the
engine. Avoid spilling any gasoline. Since gasoline
is highly flammable, handle it carefully.
A. Use an approved gasoline container.
B. Fill tiller fuel tank outdoors when engine is
cool. Engine must not be running to pre-
vent a potential hazard.
C. Wipe up any gasoline that may have spilled.
and install gasoline container cap and tiller
fuel tank cap before starting the engine.
WHILE OPERATING
6. Open doors if engine will be run in the garage,
because exhaust fumes are dangerous and could
possibly be deadly. Do not run engine indoors.
7. Do not operate the tiller if someone is near the
area to be tilled.
8. Tilling the soil demands attention. Always
maintain secure footing, balance and control.
9. Till the soil when it is dry, because wet or sticky
soil can cause mechanical damage.
10. Keep face, hands, feet and any other part of
the body or clothing away from concealed or ex-
posed rotating parts such as the tines, belts and pul-
leys. Stay behind the handles and away from the
tines while operating the tiller.
11. Release clutch control, shut engine off and
wait for all parts to stop before removing any ob-
struction from the tines.
12. If a solid object is hit by the tines or tines get
plugged, release clutch control and shut engine off.
Remove high tension wire from spark plug; then
check for possible damage, an obstruction or loose
parts. Make all repairs before using the tiller again.
13. Before leaving the operator's position — behind
handles — release clutch control and shut engine
off. Pull high tension wire off spark plug to prevent
possibility of accidental starting.
14. Do not touch the engine while it is running or
soon after it is stopped, because the engine may be
hot enough to cause a burn.
MAINTAINING TILLER
15. Before performing any maintenance or servic-
ing the tiller, shut engine off and pull high tension
wire off spark plug to prevent possibility of acci-
dental starting.
16. Perform only those maintenance instructions
described in this manual. If major repairs are ever
needed or assistance is desired, contact an Author-
ized TORO Service Dealer.
17. Keep tiller in safe operating condition by hav-
ing nuts, bolts, and screws tight.
SAFETY INSTRUCTIONS
18. To reduce potential fire hazard, make sure en-
gine and tiller chassis is free of excessive grease,
vegetation, dirt and other foreign matter.
19. Do not overspeed the engine by changing gov-
ernor settings. Recommended engine speed is
3000 rpm. To assure safety and accuracy, have an
Authorized TORO Service Dealer check maximum
engine speed (3200 rpm) with a tachometer.

PREPARATION BEFORE STARTING
FILL CRANKCASE WITH OIL
Tools Required: Pliers, Clean Rag, Funnel and Oil
Tube (provided)
IMPORTANT: The tiller is shipped from the fac-
tory without oil in the crankcase. Before starting
engine, crankcase must be filled to the proper level
with recommended oil.
IMPORTANT: Check level of oil every 5 operating
hours or each time tiller is used. Initially, change oil
after the first 2 hours of operation; thereafter, under
normal conditions, change oil after every 25 hours
of operation. Change oil more frequently when
engine is operated in only dusty or dirty conditions.
1. Move tiller to a level surface to assure accurate
oil level reading.
2. Clean the area around the oil filler plug so for-
eign matter cannot enter filler hole when plug is
removed.
3. Remove filler plug from crankcase (Fig. 4).
4, Slowly, pour approximately 20 ounces (.591 1)
of oil into crankcase using provided oil tube with
funnel (Fig. 4). The Briggs & Stratton engine uses
any high quality detergent oil having the American
Petroleum Institute — API — “service classification”
MS, SC, SD, or SE. Oil viscosity — weight — must
be selected according to the season’s ambient
temperature.
A. Summer (over 40°F, 4°C) Use S.A.E. 30
or 10W-40 oil.
B. Winter (below 40°F, 4°C) — Use S.A.E.
FILLER PLUG—® _

Filling Crankcase With Oil
5. After crankcase is filled with oil, rock the tiller
gently to release any air that may be trapped in the
crankcase. If level of oil drops, add enough to bring
It up to the point of overflowing.
6. Install filler plug into opening in crankcase.
Wipe up any oil that may have spilled.
FILL FUEL TANK WITH GASOLINE
Tools Required: Clean Rag and Funnel with Filter
Always use clean, fresh gasoline. If gasoline is al-
lowed to stand it will form gum-like varnish depos-
its in the carburetor, fuel line, and fuel tank. Such
deposits cause starting problems and poor engine
operation.
IMPORTANT: Do not mix oil w/gasoline because
engine damage and poor performance may result.
Do not use premium gas, gasohol, white gas or
gasoline additives. Either leaded-regular or low
lead gasoline is acceptable to fill the 2 quart
(1.88 1) fuel tank.
a...
Because gasoline is flammable, caution
must be used when storing or handling
it. Do not fill fuel tank while engine is
running, hot or when machine is in an
enclosed area. Vapors may build up and
be ignited by a spark or flame source
many feet away. DO NOT SMOKE
while filling the fuel tank to prevent the
possibility of an explosion. Always fill
fuel tank outside and wipe up any spilled
gasoline before starting engine. Use a
funnel or spout to prevent spilling
gasoline, and fill tank to about 1/2 inch
(12.7 mm) below the filler neck. Store
gasoline in a clean safety-approved con-
tainer and keep the cap in place on the
container. Keep gasoline in a cool, well-
ventilated place; never in an enclosed
area such as a hot storage shed. To assure
volatility, do not buy more than a 30 day
supply of gasoline. Gasoline is a fuel for
internal combustion engines; therefore,
do not use it for any other purpose. Since
many children like the smell of gas, keep
it out of their reach because the fumes
are explosive and dangerous to inhale.

PREPARATION BEFORE STARTING
1. Clean area around the fuel tank cap so foreign
matter cannot enter the tank when cap is removed.
2. Remove cap from fuel tank and fill tank with
leaded regular or low lead gasoline. Then install
fuel tank cap.
3. Wipe up any gasoline that may have spilled
while tank was being filled.
CHAIN DRIVE CASE
The chain drive case comes filled with oil. It is not
necessary to fill chain drive case unless shipping
carton shows evidence that oil has leaked out: Refer
to Filling Chain Drive Case, page 17.
Under normal operating conditions the chain drive
case need only be checked once a year to make sure
oil level is maintained. However, if there is evidence
of oil leaking from the chain case or bearings, check
oil level more frequently. If oil leaks persist contact
your nearest Authorized TORO Service Dealer.
CONTROLS
Drive Clutch Control (Fig. 5) — Clutch control is
mounted near the left handle grip. By squeezing
control against handle, pivoting idler pulley is pulled
against a V-belt; thus, forward tine engagement re-
sults. To maintain tine engagement, squeeze clutch
control continuously or depress locking pin and re-
lease control against pin. Squeeze clutch control
against handle, which will disengage locking pin,
and allow control to release: Tines and forward
movement will stop.

DRAG STAKE
Drag Stake (Fig. 14 and 15) — When the drag stake
engages the soil, it forces the tines into the soil and
eases operator effort in controlling forward advance
and overall control of the tiller. When tiller is pulled
backward, drag stake will pivot forward so move-
ment is not adversely affected.

OPERATING INSTRUCTIONS
USING THE TILLER
The tiller is a multiple-use, soil conditioning pro-
duct. It can be used to renovate a garden, flower-
bed or lawn. Soil “conditioning” occurs when the
soil is blended, mixed, aerated or pulverized by the
rotation of the tines. Two or more passes may be
required to condition soil properly; however, dif-
ferent types of soil will affect the total working
time. Wet soil tends to ball up, stick to the tines,
and may result in poor conditioning. Wet, tilled
soil may dry into rock-like lumps with a hard
crusty cover. This condition is not conducive to
seed germination and plant growth. Wet soil may
plaster onto the tine rotor, resulting in reduced
penetration when tilling. In addition, any abnor-
mal buildup of soil on the belts may cause mechan-
ical damage. Therefore, use the tiller only when
the ground is “dry” (when soil may be crumbled
with the hand), and wash tiller after use to remove
any accumulated dirt and vegetation.
Generally, there are three types of soil conditioning
applications:
1. Breaking up untilled soil.
2. Conditioning soil that has previously been
tilled.
3. Cultivating.
Before starting the engine, engage the drag stake,
and adjust wheels to the desired position. The
penetrating drag stake tends to retard forward
movement of the tiller, thus making it easier to
control. When breaking up untilled soil run engine
at maximum speed. To prevent fatigue of the
left hand, use the locking pin to hold drive clutch
control in the engaged position.
Clutch control locking pin should not be
used when tilling in confined areas or near
fences.
dE о о ооо оо e Ч
eile. dl J J EE CE i i
Initially, untilled soil and grass are broken apart
by pressing down on the handles to produce slow
forward movement and maximum rotation of the
tines; and it may even be necessary to hold back on
the handles to further reduce forward movement.
After the soil is broken apart, slight upward pres-
sure on the handles produces faster forward move-
ment of the tiller. During the actual tilling opera-
tion you may try to maneuver a turn. The compact
tiller is versatile and will react to turning maneu-
vers without any damage to the tiller. However,
experience and soil conditions will dictate degree
of turn. The tiller can be pulled backward and
turned easily, since the drag stake pivots out of
the ground.
12
To condition the soil effectively, a definite tilling
pattern must be used. Till a single row; then skip a
space equal to the width of the tines, and make the
return pass. Continue this pattern until the entire
area is broken apart. Next, condition the entire area
again by tilling at right angles to the previously tilled
swaths. When the entire area is broken up, till
deeper by raising wheels and adjusting handle force
for a slow propelling rate. A four-inch depth of
conditioned soil is deep enough for most row crops
and turf, seed-bed areas. Vine crops, however, usu-
ally require six or more inches of conditioned soil.
Another tiller application is conditioning soil that
has been tilled previously. Even though the soil has
been conditioned before, the ground must be dry
for the effective reconditioning that may be re-
quired. Do not till when the soil is wet. Engine
speed should be regulated to produce good pulver-
ization of the soil, and this is affected by the type
of soil being conditioned. Never condition the soil
until it becomes granular or powdery, because the
surface soil will have a tendency to pack and resist
plant growth. If the general texture of the soil is
somewhat sandy, use only enough engine speed to
loosen the soil for planting. Other than engine
speed, the use of the tiller and tilling pattern is the
same as when untilled is first conditioned. Keep
the wheels adjusted so that an erect, non-straining
operating position can be maintained.
When cultivating — uprooting weeds — the tiller
must be controlled carefully to avoid plant damage.
To maintain control of the tiller, adjust wheels, en-
gage drag stake, and reduce engine speed. Wheels
should be adjusted to allow the operator to main-
tain an erect position.
In summary, till or cultivate the soil when it is dry,
because better “conditioning” will result. Maximum
engine speed is required to break up soil that has
never been tilled. By comparison, regulate engine
speed as required when conditioning soil that has
already been tilled. Cultivating, by contrast, re-
quires reduced engine speed so that precise control
of the tiller can be maintained. And, after the tiller
has been used, hose off any dirt and vegetation
from the tines, pulleys, belts and shroud. Wipe en-
gine with a damp cloth, in preference to spraying it
with water. Store the tiller in a clean, dry garage
or storage shed.
IMPORTANT: 1) Always make sure that air clean-
er is cleaned and serviced before operating tiller.
2) Make sure blower and air cleaner are free of de-
bris. Clean every 4 hours when tilling dry vegeta-
tion or dry, dusty soil. If this is not done, chaff
will build up in blower housing, causing engine to
overheat.

SERVICING AIR CLEANER
Tools Required: Screwdriver
NOTE: The air cleaner element must be cleaned
after every 25 hours of engine operation. However,
element must be cleaned every few hours when op-
erating conditions are extremely dusty or sandy.
1. Pull high tension wire off spark plug.
2. Remove screw and cover to expose air cleaner
element (Fig. 20).
3. Inspect air cleaner element at the inlet holes on
the bottom of air cleaner, and at the top of the air
cleaner element. If element is dirty or discolored,
it must be removed from the air cleaner body, then
cleaned.
A. WASH element in a solution of liquid de-
tergent and water. Squeeze element to re-
move dirt, but do not twist the element,
because it may tear.

B. DRY element by wrapping it in a clean rag.
Squeeze rag and element until element is dry.
C. SATURATE element with 5 teaspoons
(25 ml) of engine oil, and squeeze element
to distribute and remove excess oil. A damp
element is desirable. Next, put element into
body. Also install screen and spacer on top
of element.
4. Install cover on air cleaner body, and make sure
cover and element form a seal. Mount air cleaner
assembly on top of carburetor with long screw.
Make sure that all parts are seated in place and
form a seal.
IMPORTANT: Do not operate engine without air
cleaner element and screw mounted in place, be-
cause engine damage will likely result.
REPLACING SPARK PLUG
Tools Required: Spark Plug Socket Wrench, Spark
Plug Gapping Tool and Clean Rag
Since air gap between center and side electrodes of
the spark plug increases gradually during normal
operation of the engine, check condition of elec-
trodes after every 25 operating hours. Recom-
mended air gap is 0.030 of an inch (0.76 mm).
Correct spark plugs to use are Champion RCJ-8 or
Autolite AR7N.
1. Clean area around spark plug so foreign matter
cannot fall into cylinder when spark plug is removed.
2. Pull high tension wire off spark plug and remove
plug from cylinder head.
13
MAINTENANCE
3. Check condition of side electrode, center elec-
trode and center electrode insulator to make sure
there is no damage.
IMPORTANT: A cracked, fouled, dirty or defective
spark plug must bereplaced. Donot sand blast, scrape
or clean electrodes because grit may eventually
release from the plug and fall into the cylinder.
The result is usually a damaged engine.
4. Set air gap between center and side electrodes
at 0.030 of an inch (0.76 mm) (Fig. 21). Install
correctly gapped spark plug with gasket seal, and
tighten plug to 15 ft-lb (20.4 N'm). If torque
wrench is not used, tighten plug firmly.
Figure 21
Air Gap Between Electrodes
5. Do not install high tension wire onto spark plug
unless tiller is to be used immediately. This pre-
vents possibility of accidental starting.
CHANGING CRANKCASE OIL
Tools Required: 3/8 Inch Open End Wrench, Shal-
low Oil Drain Pan, and Clean Rag
Check oil level after every 5 hours of operation or
each time tiller is used. Change oil after the first 2
hours of operation; thereafter, under normal con-
ditions, change oil after every 25 hours of engine
operation. However, change oil more frequently
when engine is operated in dusty or sandy condi-
tions. If possible, run engine just before changing
oil: warm oil flows better and carries out more con-
taminants than does cool oil.
1. Position tiller on level surface so oil drains com-
pletely and a true reading results when crankcase is
refilled.
14
2. Shut engine off, and pull high tension wire off
spark plug.
3. Clean area around drain plug (Fig. 22). Next,
place shallow drain pan below drain plug so oil can
run into pan.
4. Remove drain plug from crankcase, and let oil
drain into pan. To make sure that oil drains com-
pletely, tip tiller slightly to the rear.

and wipe up any oil that may have spilled.
6. With tiller parked on level surface, fill crankcase
with oil: Refer to Fill Crankcase With Oil, page 7.
CHECKING OIL LEVEL IN CHAIN CASE
Tools Required: Screwdriver and Clean Rag
Under normal operating conditions, the chain drive
case needs to be checked only once a year to make
sure oil level is maintained. However, if there is
evidence of oil leaking from the chain case or bear-
ings, check oil level more frequently. If oil leaks
persist, contact your nearest Authorized TORO
Service Dealer.
1. Position tiller on a level surface.
2. Clean area around oil level plug to prevent for-
eign matter from entering inspection hole when plug
is removed.

LUBRICATING WHEELS AND IDLER PULLEY
Tools Required: Screwdriver, SAE 30 Oil, and
Clean Rag
The wheel bushings and idler pulley must be lubri-
cated after every 15 hours of operation or, if used
less, once a year. Lubricate more frequently when
conditioris are extremely dusty or sandy.
1. Clean area around wheel bushings with rag. Lu-
bricate wheel bushing with a few drops of oil (Fig.

CARBURETOR ADJUSTMENT
Carburetors are adjusted at the factory, and nor-
mally do not need adjustment unless they have been
disassembled.
INITIAL ADJUSTMENT
Close needle valve (turn clockwise — (Fig. 32), then
open 1% turns (turn counterclockwise). This initial
adjustment will permit the engine to be started
and warmed up before making final adjustment.
FINAL ADJUSTMENT
With drive clutch control released (tines stopped)
and engine running at normal operating speed (ap-
proximately 3000 rpm without load) close the
needle valve slowly (turn clockwise) until engine
starts to lose speed (lean mixture). Then slowly
open needle valve (turn counterclockwise), past
the point of smoothest operation, until engine just
17
MAINTENANCE
begins to run unevenly. This mixture should be rich
enough for best performance under load (Fig. 32).
Hold throttle in idling position. Turn idle adjusting
screw until fast idle is obtained (1750 rpm).
Test the engine under full load. If engine tends to
stall or die out, it usually indicates that the mixture
is slightly lean, and it may be necessary to open the
needle valve slightly (1/8 to 1/4 turn counterclock-
wise) to provide a richer mixture. This richer mix-
ture may cause a slight unevenness in idling.
