HOW TO USE YOUR
TILLER
The tiller is a precision built machine designed for seed
bed preparation, cultivating, furrowing and mulching.
It is engineered to minimize the hardest work in the
vegetable or flower garden, to till the soil for planting
and cultivating, and for performing many other useful
labor saving tasks in the garden. With the proper
amount of care and maintenance, this machine will pro¬
vide the owner with many years of excellent service.
WHEEL POSITION
During digging as the tines enter the ground and the
front of the tiller lowers, the wheels must be raised to
level the unit. This is essential for proper engine opera¬
tion. This adjustment is made by removing the clevis
pin and hairpin cotter from wheel yoke, raising the
wheels to the desired height, and replacing the clevis
pin and hairpin cotter. See figure 22.
CONTROLLING SPEED AND TILLING DEPTH:
1 . Wheel Yoke Adjustment: Place wheel yoke so
that the wheels are forward (nearest point between
wheels and tines) for shallow tilling, cultivating and
transport. This will also increase the forward
speed. See figure 23. Turn yoke around (farthest
point between wheels and tines) for deep tilling.
Forward speed will decrease. See figure 23.
Wheel Yoke in
this position

position for shallow
dig, cultivating and
transport.
FIGURE 23.
2. Depth Bar Adjustment: The depth bar acts as a
brake for the tiller and controls the depth and
speed at which the machine will operate. See
figure 24. Remove the clevis pin and hairpin cot¬
ter to raise or lower depth bar.
FIGURE 24.
By increasing the depth of the depth bar, the for¬
ward speed of the machine is reduced, and the
working depth is increased. When the depth bar
is raised, the working depth of the machine is re¬
duced and the forward speed is increased. The
working depth of the machine may be predeter¬
mined by setting the depth bar and wheels so that
the wheels are about four inches from the ground
when the tines and depth bar are resting on the
ground. This setting will permit a working depth of
about four inches.
11

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 bar 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.
3. Handle Pressure: Further control of tilling depth
and travel speed can be obtained by variation of
pressure on the handles. A downward pressure on
the handles will reduce the working depth and in¬
crease the forward speed. An upward pressure on
the handles will increase the working depth and
reduce the forward speed. The type of soil and
working conditions will determine the actual set¬
ting of the depth bar and the handle pressure re¬
quired.
4. Throttle Control: The throttle control lever adjusts
the engine speed and stops the engine. With the
throttle control knob pushed completely forward,
the carburetor is in START position. Pulling the
throttle control back slightly adjusts the engine
speed to FAST. Pulling the throttle back further
reduces the engine speed to SLOW. Pull the throt¬
tle completely back to stop the engine. See figure
20 .
Use maximum engine speed for deep tilling. Move
the throttle control to SLOW when transporting the
tiller.
TRANSPORTING THE TILLER
To transport the tiller to or from the garden, raise the
depth bar to the highest position. See figure 24. With
the throttle control in SLOW position, the unit will move
under its own power, without damaging grass areas as
long as it is allowed to move freely. If the operator holds
back, it will start to dig.
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 toward movement to a slow
walking speed. With outer tines installed, the maximum
working width of the tiller is 26 inches. This width may
be reduced to 24 inches by moving the clevis pins and
hairpin cotters to the inner holes on the tine shaft. For
cultivation, remove the outer tines to obtain a tilling
width of 13 inches.
When laying out plant rows, be sure to allow enough
width to permit cultivation between the rows. In grow¬
ing corn or similar crops, check-row planting will per¬
mit 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, allow¬
ing a better stand of grass to grow. The tiller is very
useful for loosening hard soil for excavation with a
shovel. No tedious hand pickwork will be necessary.
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 work¬
ing depth. 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 making 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. Breaking up leaves and straw and mixing it
with several inches of soil causes the soil to hold
moisture longer and allows proper aeration of the plant
root system. It 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 con¬
sulted regarding soil information, planting dates, and
the most satisfactory varieties of crop for your particular
area.

CARBURETOR ADJUSTMENT
A | WARNING \
If any adjustments are made to the
engine while the engine is running
(e.g. carburetor), disengage all
clutches and tines. Keep clear of all
moving parts and be careful of
heated surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude or load.
NOTE
A DIRTY AIR CLEANER WILL CAUSE
ENGINE TO RUN ROUGH. BE CERTAIN
AIR CLEANER IS CLEAN AND AT¬
TACHED TO THE CARBURETOR
BEFORE ADJUSTING CARBURETOR.
Never make unnecessary adjustments. The factory
recommended settings are correct for most ap¬
plications.
If adjustments are needed, refer to the engine manual
packed with the tiller.
LUBRICATION
CHAIN CASE
The chain case is pre-lubricated and sealed at the fac¬
tory. It requires no checking unless the chain case is
disassembled. To fill with grease, lay the left half of the
chain case on its side, add 12 ounces of Plastilube #0
grease and assemble the right half to it. This grease
can be obtained at your nearest authorized dealer.
Order Part Number 737-0133.
MAINTENANCE
ENGINE OIL
Change the oil in the crankcase after the first two hours
of operation of your new engine and after each 25 hours
of use thereafter to insure proper lubrication of inter¬
nal parts. (Take care to remove dirt around plugs.) Be
sure oil level is maintained full to point of overflowing.
See figure 25.
To change oil, remove drain plug and tip the tiller for¬
ward while engine is warm. Replace drain plug.
Remove oil fill plug and refill with new oil of proper
grade as instructed in the engine manual. Replace oil
fill plug.
FIGURE 25.
AIR CLEANER
The air cleaner prevents damaging dirt, dust, etc., from
entering the carburetor and being forced into the engine
and is important to engine life and performance.
To service air cleaner, refer to the engine manual
packed with the tiller.
Never run your engine without air cleaner t .
pletely assembled.
CLEAN ENGINE
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.
This is an air-cooled engine and free flow of air is essen¬
tial to proper engine performance and life.
SPARK PLUG
The spark plug should be cleaned and the gap reset
at least once a season or when oil is changed. Spark
plug replacement is recommended at the start of each
mowing season; check engine manual for correct plug
type and gap specification.
BELT REPLACEMENT
If belt replacement is required, order belt or belts by
part number from your nearest authorized dealer.
1. Remove the belt cover by removing three self¬
tapping screws. A 3/8" wrench is required. See
figure 26.
13

FIGURE 26.
2. After removing three screws, lift off belt cover. See
figures 26 and 27.
3. Slip the belt off the chain case pulley first, then off
idler pulley. Remove belt from engine pulley. See
figure 28.
4. To reassemble the new belt, first place belt over
engine pulley. Be sure belt is inside two pins at
engine pulley. See figure 27.
5. Belt must be over top of idler pulley. See figure 27.
Slip end of belt over the chain case pulley.
6. Reassemble the belt cover. See figure 26.
FIGURE 27.
OFF-SEASON STORAGE
If the tiller is not to be used for a while, the following
procedure should be followed. The tines, depth bar,
chain case and wheels should be cleaned of all dirt.
It is very important that the unit be stored in a level posi¬
tion 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.
Refer to the engine manual for correct engine storage
instructions.
Just as your automobile needs professional mechanical
maintenance from time to time, so does your air-cooled
engine. Cleaning and adjusting of the carburetor and
periodic replacement of the spark plug and ignition
points is made necessary by NORMAL use.
Professional Air-Cooled Engine Service is as close as
your telephone book.
A yearly checkup or tune-up by an authorized engine
dealer is a good idea to avoid breakdowns or
delay.. do it at the end of the season, then you’re
ready for the next.
■ ^NOTE
When storing any type of power
equipment in an unventilated or
metal storage shed, care should be
taken to rustproof the equipment.
Using a light oil or silicone, coat the
equipment, especially any chains,
springs, bearings and cables.
