FIGURE 27.
TILLING
,1. Adjust depth bar by removing clevis pin and
hair pin cotter, changing bar position, then
replacing hair pin cotter and clevis pin. See
figure 17.
A. Lowering the depth bar will slow the tiller
and make it till deeper.
B. Raising the depth bar will allow the tiller
to move faster and till shallower.
C. For normal tilling, set depth bar at the fifth
or sixth hole from the top.
2. Adjust wheel yoke by removing clevis pin and
hair pin cotter, changing wheel yoke height,
and replacing clevis pin. See figure 17.
A. Raising the wheel yoke will allow the
tiller to till deeper.
B. Lowering the wheel yoke will allow the
tiller to till shallower.
C. For normal tilling set wheel height at the
second or third hole from the top.
Extremely wet soil will cause soil to ball up or
clump.
When tilling in the Fall, all vines and long grass
should be removed. This will prevent vines from
wrapping around the tine shaft which slows titling
operation.
1. The best method will be determined by the
soil condition. In some soils, the desired depth is
obtained the first time over the garden. In other
soils, the desired depth is obtained by going over
the garden two or three times. In the latter case,
the depth stake should be lowered before each
succeeding pass over the garden, and passes
should be made across the length and width of the
garden alternately. Rocks which are turned up
should be removed from the garden area.
2. Handle Pressure: Further control of tilling
depth and travel speed can be obtained by
variation of pressure on the handles.
When using the depth bar a downward pressure
on the handles will increase the working depth
and reduce the forward speed. An upward
pressure on the handles will reduce the working
depth and increase the forward speed. The type of
soil and working conditions will determine the
actual setting of the depth bar and the handle
ground, while the tiller is resting on the tines.
CULTIVATING
For cultivating, a two to three inch depth is
desirable. Setting the wheels and depth bar so
that the wheels are about two inches above the
ground, while the tiller is resting on the tines and
depth bar, will allow the machine to work at
cultivating depth. The throttle should be set to
control forward movement to a slow walking
speed. With standard tines, the working width of
the machine is 26 inches. See figure 28.
TILLING HINTS
Soil conditions are important for proper titling.
The tines will not readily penetrate dry, hard soil.
This may contribute to excessive bounce and
difficult handling of the tiller. Hard soil should be
moistened prior to tilling.
FIGURE 28.
12
Tilling width can be increased from 26 inches to
28 inches by removing the clevis pin and hair pin
cotter and sliding the outer tines out one (1) inch,
and replacing the clevis pin and hair pin colter.
See figure 29.
The compost should be worked in to a depth of six
to eight inches. This may be done by working the
length of the garden, and then by mixing separate
passes across its width. The addition of decayed
organic matter will substantially increase the
fertility of your garden. For proper decaying
action, fertilizer should be applied and worked in
with the mulch materials. The breaking up of the
leaves and straw and the mixing of it with the
several inches of soil cause the soil to hold
moisture longer and allow proper aeration of the
plant root system. This also retards the growth of
weeds.
The U.S. Department of Agriculture and various
state and local agencies offer published booklets
and expert advice on all phases of gardening.
They should be consulted regarding soil informa
tion, planting dates, and the most satisfactory
varieties of crop for your particular area.
FIGURE 29.
For cultivation, this may be reduced to 14 inches
by removing the outer tines. See figure 30.
W ■
FiGURE 30.
In laying out plant rows be sure to allow enough
width (14” to 15”) to permit cultivation between
the rows.
In growing corn or similar crops, check-row
planting will permit cross cultivation and
practically eliminate hand hoeing. The tiller has
many uses other than tilling and cultivating a
garden. One of these is the preparation of lawn
area for seeding. The tiller will prepare a deep
seed bed which will be free of hard untilled spots,
allowing a better stand of grass to grow. The tiller
is very useful for loosening hard soil for
excavation with a shovel. Your tiller may be used
for mixing compost in the pile, or for mixing it
with the soil in your garden. This should be done
after the soil has been broken to the full working
depth.
MAINTENANCE
BELT REPLACEMENT:
If belt replacement is required order belt or belts
by part number from your nearest Sears Service
Center.
FORWARD DRIVE BELT - Part No. 754-0232

CARE AND MAINTENANCE:
Transmission:
The transmission is pre-lubricated and sealed at
the factory. It requires no additional lubrication
unless the transmission is disassembled. To fill
with grease, lay the left half of the chain case on
its side, add 14 ounces of Plastilube #1 grease and
assemble the right half to it. This grease can be
from your nearest Sears Service Center. (Order
Part No. 737-0133.)
FIGURE 34.
2. Always use the PROPER FUEL in your engine.
Useonlya good grade of fresh, clean, regular
gasoline. Do not use gasoline that has been
sitting for a long period of time. Stale
gasoline may cause engine to run poorly or
not at all.
3. Keep your engine CLEAN. Wipe off all spilled
fuel and oil. Keep the engine clean of foreign
matter and be sure the cooling fins on the
cylinder are kept clean to permit proper air
circulation. You must REMEMBER that this is
an air cooled engine and free flow of air is
essential to proper engine performance and
life.
4. Your must SERVICE YOUR AIR CLEANER.
Clean every 10 operating hours, or more often
if used in extremely dusty or dirty areas.
Proceed as follows:
A. Remove wing nut, cover and filter.
B. Tap top or bottom of filter lightly on a fiat
surface to dislodge any dirt (low pressure
air blown carefully from inside of filter
may also be used)—or wash filter in water
t4
and detergent solution and flush from
inside until water is clear. Be sure filter is
completely dry before reassembling to
engine. DO NOT OIL FILTER. IF IT IS
PUNCTURED, TORN OR UNCLEANABLE,
IT SHOULD BE REPLACED. Replacement
filters are available at your nearest
Authorized Sears Service Center.
C. Before replacing filter, clean inside of
base and cover thoroughly.
D. Replace filter and cover making sure filter
is seated correctly between base and
cover. Tighten wing nut securely. See
figure 35.
NEVER RUN ENGINE WITHOUT COMPLETE AIR
CLEANER INSTALLED ON ENGINE.

ADJUSTMENTS
DO NOT MAKE UNNECESSARY ADJUSTMENTS.
FACTORY SETTINGS ARE SATISFACTORY FOR
MOST APPLICATIONS AND CONDITIONS. IF
ADJUSTMENTS ARE NEEDED, PROCEED AS
FOLLOWS:
1. Carburetor Adjustments (See figure 36.)
A. High speed adjust needle is pre-set at the
factory. (1V2 turns open)
Re-adjustment should not be necessary.
B. Close idle adjust needle by turning
clockwise. Close finger tight only. Forcing
may cause damage.
C. Open idle adjust needle by turning VA
turns counterclockwise.
D. Start engine. Follow preceding starting
instruction. Run engine a few minutes to
warm it up.
2. Remote Control Adjustments (See figure 37.)
To obtain satisfactory engine performance,
the engine and remote equipment controls
must be adjusted properly. If it is necessary
to check the engine control adjustments,
proceed as follows:
A. Set remote equipment control at FAST or
HIGH SPEED and keep it in this position.
With control in this position, control lever
should touch high speed stop. If it does,
the controls are adjusted correctly and no
fOTther adjustment should be necessary.
If control lever does not touch high speed
stop, proceed to Instruction B.
B. Loosen clamp screw just enough so remote
control cable can be moved in cable clamp
(do not remove cable clamp from control
bracket or disconnect. Remote control
cable from control lever).
C. Move control lever so it is touching high
speed stop and hold it in this position.
With control lever in this position, tighten
clamp screw so that cable clamp will hold
remote control cable in place when remote
equipment control is used.
The engine controls should now be
adjusted correctly.

FIGURE 37.
3. NEVER TAMPER WITH ENGINE GOVERNOR
WHICH IS FACTORY SET FOR PROPER
ENGINE SPEED. OVERSPEEDING ENGINE
ABOVE FACTORY HIGH SPEED SETTING
CAN BE DANGEROUS. IF YOU THINK THE
ENGINE GOVERNED HIGH SPEED NEEDS
ADJUSTING, CONTACT YOUR NEAREST
AUTHORIZED SEARS SERVICE CENTER,
WHO HAS THE PROPER EQUIPMENT AND
EXPERIENCE TO MAKE ANY NECESSARY
ADJUSTMENTS.
SPARKPLUG:
1. Remove the spark plug each time you change
the oil and inspect it. See figure 38.
A. The electrodes should be kept clean and
free OF CARBON. The presence of carbon
or excess oil will greatly deter proper
engine performance.
B. If possible, check the spark plug gap (area
between electrodes) using a wire feeler
gauge. This specification should be .030.
2. if you need a spark plug refer to the yellow
pages of your phone book under “Engines Gas
oline" for an authorized dealer.
STORAGE
If the tiller is not to be used for a while, the
following procedure should be followed. The
tines, depth bar, transmission and wheels should
be cleaned of all dirt, it is very important that the
unit be stored in a level position to prevent engine
oil from draining into the cylinder head cavity.
Engines on tillers to be stored between seasons
should be completely drained of fuel to prevent
gum deposits forming on essential carburetor
parts, and fuel tank.
///^
TILLER INSTRUCTIONS FOR WINTER
OPERATION (under 40*F.)
Engine Lubrication. Drain the summer engine oil
while engine is warm. Refill with new “winter
grade” oil. Run engine until warm to distribute the
new winter oil.
Use oil “for service” SC, SD, or SE. Use 5W-20 or
5W-30. If not available, use 10W, or 10W-30.
Fuel. Replace any summer gasoline on hand or in
the fuel tank with fresh winter-grade gasoline. Use
lead-free or leaded “regular” grade automotive
gasoline. Winter fuels have additives for faster
starting. Keep fuel tank full.
NOTE
Many automotive gasolines no long
er contain “de-icer.” A can of gas
line de-icer fluid added to yourgasoline supply will help maintain the
engine’s winter reliability.
Cold Starting Hints
1. Be sure to use proper winter-grade oil and
gasoline.
2. Declutch all possible external loads.
3. Set governor control at low-speed position.
4. Turn carburetor needle valve approximately
1 /8 turn counterclockwise. (Richer fuel
mixture) This will improve cold weather
starting and operation.
