CONTROL ASSEMBLY (See figure 7.)
Throttle Control Assembly
Assemble control lever in box on handle panel as
shown. Be sure control lever is positioned with the
hole in the control rod mounting clevis up (or to
the rear).
2. Insert the "L" shaped end of control rod through
the lower opening of the box. Screw the threaded
end of the control rod into the ferrule on the vari
able speed control. It will extend approximately
3. Insert the "L" shaped end of the control rod into
the control lever and fasten with cotter pin.
4. Remove spark plug wire. Place control lever in neu
tral. Pull recoil starter rope several times. Tines
should not rotate. If tines rotate, adjust control rod
in ferrule until "NEUTRAL" is obtained.
5. Replace spark plug wire.
CAUTION
If the belt cover (Ref. No. 63 on page
12) is removed, you will not have any
neutral. This belt guard contains the
belt trapout meant for around the en
gine pulley. The control rod must be as
sembled exactly as noted above and as
shown in figure 7 or there will be no
neutral and the tiller tines will rotate
as long as the engine runs.
Step 1. Place throttle control in handle and assemble
to handle with the two throttle screws using
a screwdriver. See figure 8.
CONTROLS
The controls on your Rotary Tiller are the control lever,
throttle control and depth bar.
The Control Lever
The Control Lever is released from Neutral by moving
it to the right and allowing the spring tension to pull
the control lever into one of the four forward speeds.
See figure 9.
NOTE
Number 1 position is the slowest tine
rotation speed and number 4 is the
fastest.
Pulling the control lever slowly backwards into Re
verse position reverses the direction of tine rotation.
Reversing should be done at half throttle position.
FIGURE 8. THROmE CONTROL
FIGURE 9. CONTROLS
The Throttle Control
The throttle control actuates the butterfly in the carbu
retor which controls the speed of the engine.
NOTE
Always check the throttle cable and
wire at the engine end for a tight con
nection.
To stop the engine, pull the throttle control all the way
back towards you. To start, push the throttle control all
the way forward. See figure 9.
The Depth Bar
The depth bar is used to prevent the tiller from running
on top of the ground instead of tilling. The deeper
you set the depth bar, the deeper you will till. Tilling
depth is from 0 to 8 inches. See figure 10.
WHEEL ADJUSTMENT
The wheel height can be adjusted by removing the
long clevis pin on the wheel hanger and raising or
lowering the setting. The higher the setting the deeper
the tilling depth. See figure 11.
NOTE
Pick a height that places the handles in
a comfortable position for the operator.
TILLING WIDTH ADJUSTMENT
The tilling width is adjustable from 12 inches to 40
inches with the use of the optional extension tines. The
standard tilling width with both the inner and outer
tines is 26 inches. By removing the outer tines you re
duce the tilling width to 12 inches.
FIGURE 11. WHEEL HEIGHT ADJUSTMENT
CHECKING OIL, GASOLINE AND CHAIN CASE
NOTE
When packaged for shipment the ma
chine contains no oil or gasoline. Before
starting the engine, oil must be added
to the engine crankcase and gasoline
to the tank. DO NOT mix oil with gaso
line.
a. Oil
With the tiller on level ground, remove the oil filler
plug from the engine and fill the crankcase with good
quality, SAE 30 type MS engine oil until it overflows.
The crankcase holds approximately 2% pints of oil.
Pour slowly to avoid air locks. Replace the oil filler
plug. See figure 18.
b. Gasoline
Remove the gas cap and fill the tank with FRESH REG
ULAR GRADE GASOLINE. If the gasoline has been in
a metal can for a long period, throw it away and use
fresh gasoline.
c. Chain Case Lubricant
The chain case is sealed and requires no further lubri
cation unless the chain case is disassembled for repair.
Step 4. When the engine starts, gradually move the
throttle to the fast position. After engine
warms up (about 2 or 3 minutes) set throttle
at idle position.
Step 5. DO NOT OVERCHOKE ENGINE. Repeated
cranking with throttle at START position will
cause gasoline to flood the intake tube and the
engine. If, after 3 or 4 attempts, the engine
fails to start, place throttle in fast position,
crank the engine several times to clear out
the excess fuel; and then proceed with steps
2, 3 and 4.
STOPPING THE ENGINE
To stop the engine, pull the throttle control all the way
back to STOP position. See figure 9. When the throt
tle control is in the STOP position, a switch blade is
activated to short-circuit the spark plug.
Whenever the tiller is left unattended,
disconnect the spark plug lead and place
the throttle control in the STOP position.
AIR FILTER
The air filter is pre-serviced at the factory and requires
no additional servicing before the initial use of the
tiller, however, the air cleaner should be serviced per
iodically as stated on page 8.
STARTING THE ENGINE
Step 1. With the tiller set on level ground, set the
control lever in NEUTRAL.
Step 2. Set the choke in the START.
Step 3. As illustrated in figure 13, grasp the recoil
starter handle, pull out sharply, and hold it
in the out position. (Do not let cord snap back.)
STOPPING THE TINES
Pull the control lever into the NEUTRAL position. The
tines will not rotate. See figure 9.
OPERATING THE TILLER
Typical operation of the tiller is as follows:
Step 1. Set the clutch control to NEUTRAL.
Step 2. Start the engine.
NOTE
To move the tiller to the work area,
keep the depth bar in the highest posi
tion. With the throttle in the SLOW posi
tion, slowly engage the control lever
into the number 1 position and the tiller
will walk to the work area without dig
ging into the ground.
Step 3. With the clutch control in NEUTRAL, set the
depth bar in one of the lower settings.
NOTE
When several passes must be made
over the same area, lower the depth bar
each time a pass is made.
Step 4. Set the throttle control to fast. (See page 5.)
FIGURE 13. RECOIL STARTER
NOTE
The cord should NOT be pulled out
more than about two feet. If engine
fails to start, allow the cord to wind
back into the housing, then pull out
sharply again. Refer to Step 5.
Step 5. Slowly engage the clutch control to the num
ber 1 position and the tines will begin rotat
ing. Number 4 position will give the maxi
mum tine speed. Tilling the ground for the
first time should be done in the number 1 or 2
position. To pulverize tne soil after it has been
tilled, move the control lever to the number 3
or 4 position.
NOTE
This tiller is equipped with a variable
speed pulley making it necessary for
the engine to be running to move
the control lever into the faster speeds.
A downward pressure on the handles
will increase working depth and re
duce the forward speed. An upward
pressure on the handles will reduce the
working depth and increase the for
ward speed. The type of soil and work
ing conditions will determine the actual
setting of the depth bar and the handle
pressure required.
If the tines stop rotating or the belt
slips, stop the engine and examine the
tine area for a rock or some object that
may be jamming the tines and prevent
them from turning. Reversing the tiller
will usually free the object.
Step 2. After the oil has been drained completely
from the crankcase, replace the drain plug and
tighten.
Step 3. With the tiller on level ground, remove the
oil filler plug (See figure 16). Fill the crankcase
until the oil overflows from the oil fill hole.
Fill slowly to avoid air locks. The crankcase
should hold approximately 2% pints of SAÉ
30 type MS engine oil. Replace the oil filler
plug.
CHAIN CASE LUBRICATION
The chain is permanently lubricated and requires no
further lubrication unless the case is disassembled for
repair.
If the case is disassembled, clean the chain with kero
sene, allow it to dry and work a high temperature
grease, such as Lubriplate No. 310 into the chain.
NOTE
If the tines tend to bounce instead of
cutting into the soil, one or more sets
of tines may be on backwards. The
cutting edge of the tines should enter
the soil first.
Step 6. To reverse the direction of rotation of the
tines, pull the control lever into the reverse
position. The control lever must be held in
reverse. See figure 9.
b. Oil Change
To avoid spilling gasoline on your lawn or driveway,
plan to change the oil when the gasoline tank and car
buretor are empty.
After the first two hours of operating a new engine,
drain the oil from the crankcase while the engine is
still hot and refill the crankcase with new oil; there
after change the oil after every 25 hours of operation.
This procedure ensures for minimum wear of engine
parts and provides for virtually trouble-free operation.
To change the oil, proceed as follows:
Step 1. With the machine on level ground, place a
suitable metal container under the oil drain
plug, then remove the drain plug. See figure
12.
NOTE
A 4 oz. container of Lubriplate No. 310
is available under part number 727-0136.
CHAIN ADJUSTMENT
No chain adjustment is necessary.
AIR FILTER
Under normal operating conditions, the air cleaner,
located on top of the carburetor, must be serviced
after every ten hours of use. Under extremely dusty
operating conditions, the air cleaner must be serviced
after every hour of operation. See figure 15.
Step 1. Remove the wing nut and cover.
Step 2. Remove the paper element from the support
base.
Step 3. To clean, tap the paper element (either top or
bottom) on a flat surface or wash in a nonsudsing detergent and flush from the inside
until the water is clear. After washing, air dry
thoroughly before using.
FIGURE 15. AIR CLEANER
CLEANING ENGINE AND TINE AREA
Any fuel or oil spilled on the tiller should be wiped
off promptly. Dirt, leaves and other debris must not be
left to accumulate around the cooling fins or the engine
or on any part of the tiller. Clean the under side of the
tine shield after each use. The dirt washes off the tine
easier if washed off immediately instead of after it
dries.
The blower housing is held in place with three screws.
One on the top of the engine and two on the bottom.
See figure 16.
BELTS
Check that belts are free of oil or dirt. Wipe the belts
periodically with a clean rag.
SPARK PLUG
The spark plug gap should be cleaned and reset to a
0.030-inch clearance every 25 hours of engine opera
tion (See figure 17). Spark plug replacement is rec
ommended at the start of each tiller season; check en
gine parts list for correct plug type.
FIGURE 18. GASOLINE FILTER AND SHUT-OFF
BELT ADJUSTMENT
How to adjust:
Step 1. Remove the belt cover as shown in figure 18.
Step 2. Start the engine according to the instructions
on page 7.
Step 3. Tip the tiller back on its wheels until the tines
clear the ground.
Step 4. Move the control lever into number four posi
tion.
NOTE
The inside belt should move to the out
side edge of the variable speed pully
so the top of the belt is almost flush
with the pulley. See figure 19.
Step 5. If adjustment is necessary, adjust the control
rod by screwing it in or out of the ferrule as
necessary. See figure 20.
GASOLINE FILTER AND SHUT-OFF VALVE
Refer to figure 18.
Step 1. Close the shut-off valve.
Step 2. Loosen the thumb screw below the bowl.
Step 3. Remove and clean the screen.
Step 4. Open the shut-off valve to see if gasoline
flows freely from the gasoline tank.
Step 5. Clean the bowl and screen. Use alcohol or
acetone to clean the parts if you find a gum
my, varnish-like substance in the bowl.
Step 6. Reassemble.
Step 7. Open the shut-off valve.

ADJUSTING THE CARBURETOR CHOKE
Proper choke and stop switch operation is dependent
upon proper adjustment of remote controls on the
powered equipment.
To Check the Operation of the Choke:
Step 1. Remove the air cleaner.
Step 2. Push the throttle control all the way forward
to the START position. See figure 10. The choke
should be closed.
Step 3. The engine should shut off when the throttle
control is ail the way back. (STOP position.)
To adjust:
Place remote control lever on equipment in fast (high
speed) position. Loosen control casing clamp screw
"B". Move control casing "A" and wire until lever "D"
touches choke operating link at "C". Tighten casing
clamp screw 'B". Replace air cleaner. See figure 24.
OFF-SEASON STORAGE
If the machine is to be inoperative for a period longer
than 30 days, the following precautions are recom
mended:
Step 1. Working outdoors, drain all fuel from the
fuel tank. Use a clean dry cloth to absorb the
small amount of fuel remaining in the tank,
then run the engine until all fuel in carburetor
is exhausted.
WARNING
L;
DO NOT DRAIN FUEL WHILE SMOKING,
OR IF NEAR AN OPEN FIRE.
Step 2. Drain all the oil from the crankcase (this
should be done after the engine has been op
erated and is still warm) and refill the crank
case with clean new oil.
Step 3. Disconnect the spark plug wire and remove
the spark plug from the cylinder. Pour about
six drops of engine oil into the cylinder, and
then pull the recoil starter several times to
spread the oil on the cylinder wall. Replace
the spark plug, but DO NOT connect the wire.
Step 4. Clean the engine and the entire tiller thor
oughly.
Step 5. Wipe tines with oiled rag to prevent rust.
