SAFETY INSTRUCTIONS
This safety alert symbol means
CAUTION, WARNING or DAN-
GER - “personal safety instruc-
tion”. Read and understand the
instruction because it has to do
with safety. Failure to comply
with the instruction may result
in personal injury.
The following “Instructions for Safe Tilling” are suggested by
The Toro Company. Failure to operate the tiller in accordance
with these Safety Instructions MAY RESULT IN PERSONAL
INJURY.
BEFORE OPERATING
1.
Read and understand the contents of this manual before
starting and operating the tiller. Become familiar with all
controls and know how to stop tiller quickly. NEVER AL-
LOW CHILDREN TO OPERATE TILLER.
Keep everyone, especially children and pets, away from
the area of operation. Remove glass, metal objects,
sticks, stones, wire and any other debris that might get
caught in or possibly be thrown by the tines.
Keep all shields and safety devices in place. If shield,
safety device or decal is defective, repair or replace it
before operation is commenced. Also tighten any loose
nuts, bolts and screws.
. Wear long pants and substantial shoes while using the
tiller. Do not operate tiller while barefoot, wearing sandals,
tennis shoes, sneakers or shorts.
Fill fuel tank with gasoline before starting the engine.
Avoid spilling any gasoline. Since gasoline is highly flam-
mable, handle it carefully.
A. Use an approved gasoline container.
B. Fill tiller fuel tank outdoors when engine is cool. En-
gine must not be running to prevent 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.
10.
11.
12.
13.
14.
Do not operate the tiller if someone is near the area to be
tilled.
Tilling the soil demands attention. Always maintain secure
footing, balance and control.
Till the soil when it is dry or moist because wet or
sticky soil can cause mechanical damage.
Keep face, hands, feet and any other part of the body or
clothing away from concealed, moving or rotating parts
such as the tines, belts and pulleys. Stay behind the
handles and away from the tines while operating the tiller.
Release clutch control, shut engine off and wait for all
parts to stop before removing any obstruction from the
tines. Use a stick to remove the obstruction.
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. Use a stick to
remove any obstruction, and make all repairs before using
the tiller again.
Before leaving the operator's position - behind handles -
release clutch control and shut engine off. Pull high ten-
sion wire off spark plug to prevent possibility of accidental
starting.
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.
16.
17.
18.
19.
Before performing any maintenance or servicing the tiller,
shut engine off and pull high tension wire off spark plug to
prevent possibility of accidental starting.
Perform only those maintenance instructions described in
this manual. If major repairs are ever needed or assis-
tance is desired, contact an Authorized TORO Service
Dealer.
Keep tiller in safe operating condition by having nuts, bolts
and screws tight.
To reduce potential fire hazard, make sure engine and
tiller chassis is free of excessive grease, vegetation, dirt
and other foreign matter.
Do not overspeed the engine by changing governor set-
tings. Recommended engine speed is 3600 rpm. To as-
sure safety and accuracy, have an Authorized TORO
Service Dealer check maximum engine speed (3600 rpm)
with a tachometer. ETT
BEFORE OPERATING
1. IMPORTANT: FILL CRANKCASE WITH OIL.
Before starting the engine, refer to the engine instructions
in the engine section. Be certain that the engine crankcase
is filled with the proper type oil and that all engine service
instructions have been followed completely (see page 13).
2. Fill fuel tank with a clean, fresh, low-lead or leaded “regu-
lar” grade of automotive gasoline. Do not use “gasohol”.
Do not mix oil with gasoline.
3. All nuts and bolts should be checked and tightened during
the first two (2) hours of use. Periodic checks should be
made thereafter.
4. The tires are normally over-inflated for shipping. The re-
commended tire pressure is 20 Ibs.
CONTROLS
ENGINE CHOKE
See engine section, page 13.
ENGINE REWIND STARTER
See engine section, page 13.
ENGINE THROTTLE CONTROL AND STOP LEVER
This control regulates the engine speed from idle to fast and
also stops the engine. (See Fig. 1 for location of control.) To
idle engine pull throttle control back. To increase speed push
throttle control forward. To stop engine pull throttle control all
the way back.
HANDLE CONTROL LEVER
The handle control lever unlocks the handle so the operator
may change the handle swing position and the handle height.
The handle control lever is under the center of the handle
panel (see Figure 1).
The handle has one (1) transport position (over the engine)
and seven (7) tilling positions (over the tines). (Notice the
locking notches where the handle pivot assembly, Fig. 2,
attaches to your tiller frame.) In each of the (8) swing positions,
three (3) handle heights are available.
To Adjust Handle Swing Position: Pull back on handle
control lever and swing handle to the transport position or any
one of the (7) tilling positions. Release the control lever and
swing the handle back and forth slightly until handle locks in
position. To Adjust Handle Height: Pull back on handle
control lever; without swinging handle, raise or lower handle to
desired height. Release control lever and move handle up
and down slightly until handle locks in position. NOTE: When
pulling back on the handle control lever, the clutch control
lever is automatically moved to the neutral position. However,
for easier operation, move clutch control lever to neutral
position before pulling handle control lever.
CLUTCH CONTROL LEVER
The clutch control lever is a single lever that engages and
disengages drive to both the tines and the wheels.

When the handie bar is in the tilling location, pushing
forward on the control lever engages the drive to both the tines
and the wheels at a tilling speed. CAUTION: Before pushing
lever forward, be certain depth control setting is correct for soil
conditions. (See "Depth Control Lever”)
Pulling back on clutch control lever from forward drive to
neutral disengages ine drive to the tines and wheels. Further
pulling back on the lever engages the reverse drive to the
wheels and the tiller moves backwards at transport speed.
(Tines do not rotate in reverse.) When released, the control
lever will return to neutral position.
When the handle bar is in transport location, the clutch
control lever will only operate by pulling the lever back. This
engages the drive to the wheels and the tiller moves forward at
transport speed. When released, the control lever returns to
neutral.
CONTROLS AND OPERATING INSTRUCTIONS
GROUND SPEED LEVER
The ground speed lever (Figure 1) controls the forward
speed the tiller travels while tilling. It is located at the top-
front section of the belt guard. The lever has five settings.
The uppermost setting is for faster speed. The lowest
setting is for slowest speed. The faster speeds are used in
lighter soils and for cultivating while the slower speed is
used in heavier soils and sod breaking.
DEPTH CONTROL LEVER
CAUTION: Do not adjust tilling depth with the
tines rotating. Place clutch control lever in the
neutral position before making adjustments of
depth control.
The depth control lever, Fig. 3, is the "key to easy tilling
operation. The exact setting of control will vary with soil condi-
tions. To Operate: Push lever forward then lift or lower to
desired position.
CAUTION: If depth control is set too deep in hard or
urworked ground, the tines will propel the tiller
NN forward pushing the drive wheels along the ground at
an uncontrolled speed.
When starting a tilling operation, start with the depth control
lever in the shallowest setting (Figure 3). As you become
acquainted with the soil, gradually raise the control lever (one
notch at a time) so that deeper tilling can be done. This will
prevent the uncontrolled forward speed that may occur if the
depth control is set too deep too soon.
NOTE: On some models, the lowest notches on depth bar will
not engage and are not intended to be used.
“FREE WHEEL" CONTROL
This control enables you to push the tiller easily. To “Free
Wheel”, pull klik pin out of wheel hub and axle and insert
pin into the outer hole of the axle. This permits the wheels
to turn freely about the axle. NOTE: Be sure the klik pins
are replaced through the wheel hubs and inner holes on
axle before operating tiller (see Illustration A).
OPERATING SUGGESTIONS
When you start to till in the garden, remember to take it easy.
Do not try to take too deep a cut in a pass through sod or hard
ground, or soil that has not been tilled for several months or
years.
Do not lean on the handle bars because this takes weight oft
the front wheels, reduces traction, and causes the tines to
attempt to propel the tiller instead of just digging.
There are several schools of thought as to the best method to
till. It 1s suggested you try the various methods and select the
one you are most comfortable with to get the resuits you
desire.

B. On the second pass, leave a "2 width untilled and till this
width on the third pass. Repeat on the fourth pass, leaving
a 2 width untilled and on the fifth pass, till the untilled strip.
C. Use Aor B and repeat at 90 degrees.
Remember the key to easy tilling is the depth control setting.
Do not try to take too deep a cut in harder soils.
CONTROLS AND OPERATING INSTRUCTIONS
STARTING THE TILLER
Now that you have located the controls and understand
their operation and function, it is time to start your tiller.
1. Move the tiller to suitable ground.
2. Place clutch control lever in neutral.
3. Pull throttle control to fast position.
4. Adjust engine choke to proper position. (Refer to engine
starting procedures in engine section, page 14.)
5. Start engine by pulling starter cord.
NOTE: Allow engine a minute or two to warm up. (Open
choke gradually as engine warms.) Operate tiller in
forward and reverse, and in all settings of the ground
speed control lever. Try all operating controls and various
handle positions.
To Stop Engine
1. Place clutch control lever in neutral position.
2. Pull throttle control and engine stop lever to the stop
position.
MAINTENANCE
ADJUSTMENTS
CAUTION: Never attempt to make adjustments on
the tiller while the engine is running. Always stop the
engine and disconnect the wire from the spark plug
before attempting to make adjustmenis.
BELT ADJUSTMENTS
Belts which are not adjusted correctly can make the tiller
difficult to shift or cause the tiller to jump out of gear
during operation. Adjust belts as follows:
TINE DRIVE BELT
The tine drive belt, which is the innermost belt, is ad-
justed by loosening the clamp bolt located under the tine
shield and loosening the front tine shield bolt (pivot bolt)
and rotating the entire case and tine assembly (see Figure
4). Rotate the case forward to slacken belt and back to
tighten belt. With the clutch control lever in neutral, the
belt should be slack enough that the tines do not rotate.
With the clutch control lever in forward drive position, the
tine drive idler arm compression spring should be
compressed ' to % of an inch from the roll pin (see Figure
5).
REVERSE WHEEL DRIVE BELT
This belt is self-adjusted by a spring loaded idler pulley.

the handle control lever (Figure 7) becomes loose after position.
many hours of operation, tighten the adjustment nut only
enough to eliminate any excess movement in the handle
control lever. 7
MAINTENANCE
CLUTCH CONTROL LEVER ADJUSTMENT
The clutch control lever is pre-set for neutral shift position.
An adjustment means is provided, however, to center the
clutch control lever in the slot on the handle shroud should
it become necessary due to wear. This adjustment is
located at the handle pivot point (Figure 8).
TO ADJUST:
1. Place handle bar in tilling location and adjust handle
bar to lowest position.
2. Loosen the adjustment nut (Figure 8).
3. Move the clutch control lever on the handle bar until
centered in the neutral area (Figure 9).
4. Retighten the adjustment nut (Figure 8).
LUBRICATION
The best assurance you have of getting the mostdependa-
ble service from your tiller is to keep the unit clean, free of
rust, and well lubricated. Check bolts often to be sure they
are kept tight. When the tiller is not being used, it should be
stored in a dry place out of the weather,
IMPORTANT! Apply oil and grease carefully and only
where required. Oil or grease on drive belts or pulleys will
cause slippage and loss of drive. Wipe up all spills or
excess oil and grease completely.
1. Engine: Refer to engine section for operating instructions
and lubrication requirements.
2. Chain Cases: Both the wheel drive and the tine drive
cases are amply filled with lubricant and should not
require additional lubrication. If a leak develops, add
(EP) SAE 140 heavy duty oil as required to bring to
proper oil level. Check oil level every 25 hours.
The following procedure should be followed to check
lubricant level of cases. When checking cases, do not
drain excess lubricant out of the cases.
WHEEL DRIVE CASE
To check the oil level of the wheel drive case, place the
depth control lever down to the shallowest setting (Figure
3). Remove the inspection plug on the right side of the
wheel drive case (Figure 10). Case has sufficient oil if oil is
up to bottom of inspection plug hole. It may be more
convenient to remove the right wheel when checking this
level.
If oil isn’t up to bottom of hole, remove counter-weight for
easier filling. Fill slowly with (EP) SAE 140 heavy duty oil
until proper level is reached. Replace oil fill plug. Wipe off
excess oil.

spark plug. Reform terminal if necessary.
REMOVE COMBUSTION DEPOSITS every 100-300 hours of
operation. Remove cylinder head and cylinder head shield.
Scrape and wire brush the combustion deposits from cylinder,
cylinder head, top of piston and around valves. Use a soft
brush to remove deposits. Re-assemble gasket, cylinder head
and cylinder head shield. Turn screws down finger tight with
the three longer screws around the exhaust valve, if so equip-
ped. Torque cylinder head screws in a staggered sequence to

ADJUSTMENTS
CARBURETOR ADJUSTMENTS
Minor carburetor adjustment may be required to compensate
for differences in fuel, temperature, altitude or load.
NOTE: The air cleaner must be assembled to carburetor
when running engine.
TO ADJUST CARBURETOR — Gently turn needle valve
clockwise until it just closes. Valves may be damaged by
turning them in too far.
Next, open the needle valve 12 turns counterclockwise. This
initial adjustment will permit the engine to be started and
warmed up (approximately 5 minutes) prior to final adjust-
ment.

FINAL ADJUSTMENT
Place governor speed control lever in “FAST” position.
Turn needle valve in until engine slows (clockwise — lean
mixture). Then turn it out past smooth operating point
(rich mixture). Now turn needle valve to mid-point
between rich and lean. Next, adjust idle RPM. Rotate
throttle counterclockwise and hold against stop. Adjust
idle speed adjusting screw to obtain 1750 RPM. Holding
throttle against idle stop, turn idle valve in (lean) and out
(rich). Set at midpoint between rich and lean. Recheck
idle RPM. Release throttle. If engine will not accelerate
properly, the carburetor should be re-adjusted, usually to
a slightly richer mixture.

CONTROL ADJUSTMENTS
Proper speed control operation is dependent upon proper
adjustment of speed controls on the powered equipment.
SPEED CONTROL ADJUSTMENT
The acceptable operating speed range is 1800 to 3600 RPM.
Idle speed is 1750 RPM. DO NOT EXCEED 3600 RPM.
SPEED CONTROL
Engine throttle control should move governor speed
control lever in direction illustrated to increase speed.
Casing from engine throttle control is connected as
shown. Wire travel is shown by arrows. NOTE: Clamp may
be loosened and casing position adjusted, if necessary, to
allow for full range of lever movement.

loading should not exceed 85% of this rating. Engine
power will decrease 37% for each 1,000 feet (304.8 m)
above sea level and 1% for each 10° above 60°F (16° C).
In some areas, local law requires the use of a resistor spark
plug so as to suppress ignition signals. If an engine was
originally equipped with a resistor spark plug, be sure to use
the same type of spark plug for replacement.

STORAGE INSTRUCTIONS
Engines to be stored over 30 days should be completely
drained of fuel to prevent gum deposits forming on essential
carburetor parts, fuel filter and tank.
NOTE: The use of a fuel additive, such as STA-BIL, or an
equivalent, will minimize the formation of fuel gum deposits
during storage. Such an additive may be added to the gasoline
in the fuel tank of the engine, or to the gasoline in a storage
container.
a. All fuel should be removed from the tank. Run the engine
until it stops from lack of fuel. The small amount of fuel that
remains in the sump of the tank should be removed by
absorbing it with a clean, dry cloth.
b. While engine is still warm, drain oil from crankcase. Refill
with fresh oil.
c. Remove spark plug, pour approximately one ounce
(30 cc) of engine oil into cylinder and crank slowly to
distribute oil. Replace spark plug.
d. Clean dirt and chaff from cylinder, cylinder head fins,
blower housing, rotating screen and muffler areas.
e. Store in a clean and dry area.
