ACCESSORIES
TINE EXTENSION SET (Mfg. No. 1600406)
See Figure 1. The extension set consists of a left and right
tine assemblies with mounting pins and cotter pins. Mount
long hub of extension over outside end of standard tine
assembly and secure assemblies together with pin and cotter
pin. Be sure sharpened edges of tines on top face forward.
The extension set increases effective tilling width to 35
inches.
ASSEMBLING
1. Remove all components of tiller from box and place them
in a clean, level area. Inspect each part for damage.
FURROW OPENER, 8-INCH (Mfg. No. 1600373)
See Figure 2. The furrow opener is intended for digging
furrows for crops which must be planted in rows. To install,
proceed as follows:
1. Remove the depth bar, turn it upside down and bolt it
to the tool holder (A) with the carriage bolts, washers and
nuts provided.
2. Remove the stop plate from between the frame supports
and install the extension support (B) with the old hardware.
3. Position the depth bar in the extension support and re
install the depth bar clamp using the pin and spring clip
provided. Bolt the furrow opener to the tool holder as
shown.
2. Remove belt cover.
3. See Figure 3. Assemble left and right handles to frame as
shown. Note locations of flat washers.
SPECIAL WORM GEAR OIL
CAUTION
Damage to the worm gear drive which results from
use of any lubricant other than that specified, will
invalidate the warranty. (See back cover for special
Worm Gear Oil Part Number).
4. Connect throttle cable as follows:
a. See Figure 8. Move throttle control handle to FAST
position. Be sure throttle cable wire is securely attached
to throttle arm under control panel. From the throttle
arm, the throttle cable must be secured to the right
handle with a clip. The cable must then pass outside the
right side of the cover and through a engine cable clamp.
Loosen engine cable clamp screw as required. See Figure
4.
c. See Figure 5. Adjust spring tension by loosening clamp
setscrews and moving clamps on control rods. Idler
pulleys should be 1/4-inch from frame when clutch dis
engaged (handle released). Belt stops should be 1/8-inch
from belts when clutch engaged (handle compressed. See
Adjustments section of this manual for clutch adjustment
procedure.
d. Secure cover to frame with six self-tapping screws.
6. Install wheel assemblies as follows:
a. Tilt unit forward on engine.
b. See Figure 6. Secure each wheel assembly (bushing
inward) to frame through lower holes in frame support
with a 3-1/2-inch long shoulder bolt, lockwasher, and
hex nut. Tighten hex nut.
b. See Figure 4. Insert loose wire end of throttle cable
in carburetor throttle arm. Lever should be in forward
position against stop in slot. Tighten engine cable clamp
screw.
c. See Figure 8. Move throttle control handle to STOP
position. Be sure stop switch opens. See Figure 4.
5. Install forward and reverse control rods as follows:
a. See Figure 5. Attach reverse and forward control rod
springs to bellcranks.
b. See Figure 5. Slide reverse and forward control rods
through wire clamps inside springs. Loosely secure rods
in clamps with setscrews and flat washers. Hook loose
end of springs on setscrews between flat washers and
clamos.
7. See Figure 6. Secure depth bar and clamp to rear of
frame with pin and hairpin clip. Digging tip of bar should
be installed as shown.
NOTE: The depth bar setting determines the depth of
tilling. To till 4 to 6 inches deep, install bar mounting pin
in second or third hole from the top. The deeper depth bar
is set into soil, the deeper tines will dig.
8. Loosen each wheel scraper nut and adjust scraper to
clear wheel by 1/8-inch. Tighten scraper nut.
9. Depending upon what tilling width desired, install right
and left tine blade assemblies as follows. Use a pin and
hairpin clip for installation. See Figure 7 for right inner,
outer and extension tine installation.

2. Engine
a. MANUALS. Read the engine owner's manual and this
operator's manual thoroughly.
b. FUEL. See Figure 9. Have available sufficient quan
tities of clean, fresh (leaded or non-leaded), "regular"
automotive gEisoline. Remove fuel tank cap and fill
tank completely. Fuel capacity is 4 quarts.:
PREPARING
1. Controls
See Figure 8. Familiarize yourself with the following con
trols;
a. THROTTLE LEVER. Used to adjust ground speed or
to stop engine. See Figure 8 for throttle lever position
ing.
b. FORWARD AND REVERSE CLUTCH LEVERS.
Used to control forward or reverse action of the tiller.
Squeeze desired lever to engage and release to stop.
DO NOT MIX OIL WITH GASOLINE.
WARNING
Gasoline is highly inflammable. Avoid overfilling and
wipe up any spilled fuel. Allow no open flame, smok
ing or matches near the area when refueling.
Replace filler cap securely. Store gasoline only in small
quantities, prolonged storage produces gum and harmful
deposits. If it is necessary to store gasoline for long periods,
add a gasoline stabilizer. See Off-Season Storage section of
this manual.
c. OIL. See Figure 9. Have available sufficient quantitiesof engine crankcase oil, SAE 30 grade MS. Remove
dirt around engine filler plug. Remove engine filler plug
by turning counter-clockwise. Fill with oil until level
with top of neck. Crankcase capacity is 2-3/4 pints.
Reinstall filler plug securely. Check oil everytime fuel
is added.
3. Depth Bar
See Adjustments section of this manual.
4. Wheels and Scraper.
f. If engine still fails to start, check fuel supply and
spark plug connections. Be sure engine stop switch is
closed (See Figure 4).
2. Operating
a. When operating the tiller for the first time, proceed
slowly and carefully to get the feel of the unit. Experi
ence will determine pressure and depth bar setting for
the operator.
b. Do not till when the soil is very wet. This causes
lumps which are difficult to work up. If the soil is ex
tremely hard and dry, it may be desireable to cross till an
area at shallow depth at first, then till in the direction
of planting rows on the second pass at the final depth.
Use reverse for working in tight areas and to dislodge
any rocks which may be caught between the tines and
worm gear housing.
c. Do not attempt to hold tiller back to cause the tines
to dig. Rather, adjust the depth bar so it will hold the
tiller back for you. When the tines have dug deep enough
in an area, raise up slightly on handles and the tiller will
move ahead. To stop the forward motion of the tiller,
put slight down pressure on the handles and the depth
bar will hold the tiller in place.
See Figure 6. Be sure wheels are mounted in the LOWER
holes of the frame support. If required, adjust wheel
scraper 1/8-inch above tire.
5. Tines
Be sure tines are installed securely with pin and cotter pin
Sharpened edges at the top must face forward. See As
sembly section of this manual for tine installation.
OPERATING
1. Starting
a. See Figure 8. Move throttle lever halfway between
SLOW and FAST position.
b. See Figure 4. Move choke lever to full CHOKE po
sition. If engine warm, use half choke. Choke arm should
be at right angles to exhaust tubing when in CLOSED
CHOKE position and parallel to tubing when in OPEN
CHOKE position,
c. See Figure 9. Be sure fuel valve is open.
d. To start engine, grasp starter grip (See Figure 9)
firmly in right hand and pull sharply straight out. Always
return grip by hand. Do not release the grip with rope
extended. Repeat if necessary with choke open slightly
(See Figure 4.) When engine starts, open choke grad
ually.
e. If engine fails to start after four or five pulls, it may
be flooded. Return choke to OPEN position and pull
out grip several times to clear excess fuel.
d. A furrow opener shovel is available for use in digging
furrows for crops which are planted in rows, such as po
tatoes. See Accessories section of this manual.
3. Stopping
a. Move the throttle lever (See Figure 8) to the STOP
position. The stop switch (See Figure 4) should open,
stopping the engine.
b. If the tiller has been operating under full load, allow
engine to idle for a minute to reduce engine temperature.
Stopping a hot engine suddenly may damage engine parts.
ADJUSTMENTS
BELT STOPS
All belt stops should be 1/8-inch from belts when clutch
engaged (handle compressed). To adjust, remove belt cover,
loosen stop mounting bolt, squeeze one clutch lever and
then the other, adjusting belt stop (sLas indicated in Figure
10. Tighten belt stop mounting bolt and replace cover.
NOTE: If tines will not stop turning after clutch lever is
released, belt stops may be too far from belts and not
braking belt as required when clutch handle released.
