SPARK ARRESTER WARNING TO RESIDENTS  
OF CALIFORNIA AND SEVERAL OTHER STATES  
Under California law, and under the laws of sev-  
eral other states, you are not permitted to operate an  
internal combustion engine using hydrocarbon fuels  
on any forest, brush, hay, grain, or grass covered  
land; or land covered by any flammable agricultural  
crop without an engine spark arrester in continuous  
effective working order.

The engine on the unit is an internal combustion  
engine which burns gasoline, a hydrocarbon fuel,  
and must be equipped with a spark arrester muffler  
in continuous effective working order. The spark  
arrester must be attached to the engine exhaust  
system in such a manner that flames or heat from  
the system will not ignite flammable material.  
Failure of the owner/operator of the unit to comply  
with this regulation is a misdemeanor under Cali-  
fornia law (and other states) and may also be a viola-  
tion of other state and/or federal regulations, laws,  
ordinances or codes. Contact your local fire marshal

operating precautions to assist you in  
maintaining control of the tiller:  
24. Do not touch engine parts which may  
be hot from operation. Let parts cool down  
sufficiently.  
5. If the unit should start to vibrate abnor-  
mally, stop the engine, disconnect the  
spark plug wire and prevent it from  
touching the spark plug, and check imme-  
diately for the cause. Vibration is gener-  
ally a warning of trouble.  
a. Walk behind and to one side of the  
tiller, using one hand on the han-  
dlebars. Relax your arm, but use a  
secure hand grip.  
25. Please remember: You can always  
stop the tines and wheels by releasing the  
Forward Clutch Bail or by moving the igni-  
tion switch and/or throttle control lever on  
the engine to “OFF” or “STOP”.  
b. Use shallower depth regulator set-  
tings, working gradually deeper  
with each pass.  
6. Stop the engine, disconnect the spark  
plug wire and prevent it from touching the  
spark plug, whenever you leave the oper-  
ating position, before unclogging the tines,  
or when making any repairs, adjustments  
or inspections.  
26. To load or unload the tiller, see the  
instructions in Section 4 of this Manual.  
c. Use slower engine speeds.  
d. Clear the tilling area of all large  
stones, roots and other debris.  
27. Use extreme caution when reversing  
or pulling the machine towards you.  
e. Avoid using downward pressure on  
the handlebars. If need be, use  
slight upward pressure to keep the  
tines from digging too deeply.  
28. Start the engine carefully according to  
instructions and with feet well away from  
the tines.  
7. Take all possible precautions when  
leaving the machine unattended. Stop the  
engine. Disconnect the spark plug wire  
and move it away from the spark plug. Be  
sure that both wheels are in the Wheel  
Drive position.  
29. Never pick up or carry a machine  
while the engine is running.  
f. Before contacting hard packed soil  
at the end of a row, reduce engine  
speed and lift the handlebars to  
raise the tines out of the soil.  
Maintenance and Storage  
1. Keep the tiller, attachments and acces-  
sories in safe working condition.  
8. Before cleaning, repairing, or  
g. In an emergency, stop the tines and  
wheels by releasing whichever  
clutch control is engaged. Do not  
attempt to restrain the tiller.  
inspecting, stop the engine and make cer-  
tain all moving parts have stopped. Dis-  
connect the spark plug wire and prevent it  
from touching the spark plug to prevent  
accidental starting.  
2. Check all nuts, bolts, and screws at  
frequent intervals for proper tightness to  
be sure the equipment is in safe working  
condition.  
15. Do not overload the tiller’s capacity by  
attempting to till too deeply at too fast a  
rate.  
9. The flap on the tine hood must be down  
when operating the tiller.  
3. Never store the tiller with fuel in the fuel  
tank inside a building where ignition  
sources are present such as hot water and  
space heaters, furnaces, clothes dryers,  
stoves, electric motors, etc.). Allow the  
engine to cool before storing the unit in  
any enclosure.  
16. Never operate the tiller at high trans-  
port speeds on hard or slippery surfaces.  
Look behind and use care when backing  
up.  
10. Never use the tiller unless proper  
guards, plates, or other safety protective  
devices are in place.  
11. Do not run the engine in an enclosed  
area. Engine exhaust contains carbon  
monoxide gas, a deadly poison that is  
odorless, colorless, and tasteless.  
17. Do not operate the tiller on a slope  
that is too steep for safety. When on  
slopes, slow down and make sure you  
have good footing. Never permit the tiller  
to freewheel down slopes.  
4. To reduce the chances of a fire hazard,  
keep the engine free of grass, leaves, or  
excessive grease.  
12. Keep children and pets away.  
5. Store gasoline in a cool, well-ventilated  
area, safely away from any spark- or  
flame-producing equipment. Store gaso-  
line in an approved container, safely away  
from the reach of children.  
18. Never allow bystanders near the unit.  
13. Never operate the tiller under engine  
power if the wheels are in the Freewheel  
position. In the Freewheel position, the  
wheels will not hold the tiller back and the  
revolving tines could propel the tiller  
rapidly, possibly causing loss of control.  
Always engage the wheels with the wheel  
drive pins in the Wheel Drive position  
before starting the engine or engaging the  
tines/wheels with the Forward Clutch Bail.  
19. Only use attachments and accessories  
that are approved by the manufacturer of  
the tiller.  
20. Use tiller attachments and accessories  
when recommended.  
6. Refer to the Maintenance sections of  
this Manual and the separate Engine  
Owner’s Manual for instructions if the unit  
is to be stored for an extended period.  
21. Never operate the tiller without good  
visibility or light.

or under the influence of alcohol, drugs or  
medication.  
engine is running or the spark plug wire is  
connected, except when specifically  
instructed to do so.  
14. Be aware that the tiller may unex-  
pectedly bounce upward or jump forward  
if the tines should strike extremely hard  
packed soil, frozen ground, or buried  
obstacles like large stones, roots, or  
stumps. If in doubt about the tilling con-  
ditions, always use the following  
23. Operators shall not tamper with the  
engine-governor settings on the machine;  
the governor controls the maximum safe  
operating speed to protect the engine and  
all moving parts from damage caused by  
overspeed. Authorized service shall be  
sought if a problem exists.

Before starting the engine, put both  
wheels in the WHEEL DRIVE position by  
inserting the wheel drive pins through the  
wheel hubs and the wheel shaft. Doing so  
“locks” the wheels to the wheel shaft,  
causing the wheels to turn when the For-  
ward Clutch Bail is engaged.

DEPTH REGULATOR LEVER  
Figure 3-3: FREEWHEEL position.  
This lever (G, Figure 3-5) controls the  
tilling depth of the tines. Pull the lever  
back and slide it up or down to engage the  
notched height settings.  
HANDLEBAR HEIGHT ADJUSTMENT  
The handlebar height is adjustable to three  
different settings (Figure 3-6). In general,  
adjust the handlebars so they are at waist  
level when the tines are 3"-4" in the soil.  
WARNING  
Before starting engine, be sure that both The “travel position” (highest notch) raises

the tines approximately 1-1/2" off the  
ground, allowing the tiller to be moved  
without the tines contacting the ground.  
This setting should also be used when  
starting the engine.  
Engaging the Forward Clutch Bail when  
the wheels are not in WHEEL DRIVE  
could allow the tines to rapidly propel  
the tiller forward.  
To adjust the handlebars:  
1. Stop engine, disconnect spark plug  
wire from spark plug and allow engine to  
cool.  
Moving the lever upward will increase the  
tilling depth. The lowest notch allows a  
tilling depth of approximately 6",  
depending on soil conditions. For best  
results, always begin tilling at a very  
shallow depth setting and gradually  
increase the tilling depth.  
Failure to comply could cause loss of  
tiller control, property damage, or per-  
sonal injury.  
2. Remove hardware, reposition handle-  
bars, and reinstall hardware securely.

6. To Turn the Tiller Around:  
WARNING  
(a) Practice turning the tiller in a level,  
open area. Be very careful to keep  
your feet and legs away from the tines.  
(b) To begin a turn, lift the handlebars until  
the tines are out of the ground and the  
engine and tines are balanced over the  
wheels (Fig. 4-3).  
Keep away from rotating tines. Rotating  
tines will cause injury.  
(c) With tiller balanced, push sideways on  
handlebar to steer in direction of turn  
(Fig. 4-4). After turning, slowly lower  
tines into soil to resume tilling.  
Stopping the Engine and Tiller  
1. To stop the wheels and tines, release  
the Forward Clutch Bail.  
2. To stop the engine, put the ignition  
switch and/or the throttle control lever in  
the “OFF” or “STOP” position.  
Fig. 4-2: Use one hand to guide tiller when  
moving forward.  
(b) When tilling, relax and let the wheels  
pull the unit while the tines dig. Walk  
behind and a little to one side of the  
unit. Use one hand, yet keep a light—  
but secure—grip on the handlebar  
(while keeping your arm loose). See  
Fig. 4-2. Let the unit move at its own  
pace and do not push down on the  
handlebars to try and force the tines to  
dig deeper — this takes weight off the  
wheels, reduces traction, and causes  
the tines to try and propel the tiller.  
OPERATING THE TILLER  
The following operating instructions pro-  
vide guidelines to using your tiller effec-  
tively and safely. Be sure to read Tilling  
Tips & Techniques in this Section before  
actually putting the tines into the soil.  
NOTE: This is a traditional “Standard-  
Rotating-Tine” (SRT) tiller with forward  
rotating tines. It operates completely dif-  
ferently from “Counter-Rotating-Tine”  
(CRT) tillers or from front-tine tillers.  
Fig. 4-3: To begin turn, lift handlebars until  
tines are out of ground and unit is balanced.  
WARNING  
1. Follow the Pre-Start Checklist at the  
beginning of this Section. Be sure that the  
wheels are in the WHEEL DRIVE position.  
Do not push down on the handlebars to  
try to make the tiller till more deeply.  
This prevents the wheels from holding  
the tiller back and can allow the tines  
to rapidly propel the tiller forward,  
which could result in loss of control,  
property damage, or personal injury.  
2. Move the Depth Regulator Lever all the  
way down, so that the tines clear the  
ground. Use this position when practicing  
with the tiller and when traveling between  
tilling sites. Before actually tilling, move  
the lever to the desired depth setting (see  
Tilling Tips & Techniques).  
5. To move the tiller in reverse for short  
distances:  
Fig. 4-4: With tines out of ground, push  
handlebars sideways to turn tiller.  
3. Start engine and allow it to warm up.  
Then put throttle in “FAST” setting.  
(a) Release Forward Clutch Bail. Then lift  
handlebar until tines are off the ground.  
DO NOT TILL WHILE PULLING THE  
TILLER BACK TOWARD YOU.  
4. For forward motion of the wheels and  
tines:  
Stopping the Tiller and Engine  
1. To stop the wheels and tines, release  
the Forward Clutch Bail.  
(a) Pull Forward Clutch Bail (Fig. 4-1) up  
against handlebar. Release bail to stop  
forward motion of wheels and tines.  
(b) Swing the handlebar to the left so the  
right wheel takes a “step” backward.  
Next swing the handlebar to the right so  
the left wheel “steps” backward. Repeat  
as needed.  
2. To stop the engine, put the ignition  
switch and/or the throttle control lever in  
the “OFF” or “STOP” position.  
(c) If longer distances need to be covered  
in reverse, shut off the engine, then  
place the two wheels in FREEWHEEL.

Section 4: Operation  
TILLING TIPS & TECHNIQUES  
Tilling Depths  
• Avoid pushing down on the handlebars in an attempt to force the tiller to dig deeper. Doing  
so takes the weight off the powered wheels, causing them to lose traction. Without the  
wheels helping to hold the tiller back, the tines will attempt to propel the tiller – often  
causing the tiller to skip rapidly across the ground. (Sometimes, slight downward pressure  
on the handlebars will help get through a particularly tough section of sod or unbroken  
ground, but in most cases this won’t be necessary.)  
WARNING  
Before tilling, contact your tele-  
phone or utilities company and  
inquire if underground equipment  
or lines are used on your property.  
Do not till near buried electric  
cables, telephone lines, pipes or  
hoses.  
• Avoid trying to dig too deeply too quickly, especially when busting sod or when tilling soil  
that hasn’t been tilled for some time. Use shallow depth regulator settings (only an inch or  
two deep) for the first passes through the soil. With each succeeding pass, dig another inch  
or two deeper. (Watering the area a few days prior to tilling will make tilling easier, as will  
letting the newly worked soil set for a day or two before making a final, deep tilling pass.)  
• When cultivating (breaking up surface soil around plants to destroy weeds, see Fig. 4-8), adjust the tines to dig only 1" to 2" deep.  
Using shallow tilling depths helps prevent injury to plants whose roots often grow close to the surface. If needed, lift up on the handle-  
bars slightly to prevent the tines from digging too deeply. (Cultivating on a regular basis not only eliminates weeds, it also loosens and  
aerates the soil for better moisture absorption and faster plant growth.)  
Choosing Correct  
Wheel and Tine Speeds  
With experience, you will find the “just right” tilling depth and tilling speed combination that is best  
for your garden.  
Set the engine throttle lever at a speed to give the engine adequate power and yet allow it to operate at the slowest possible speed...at  
least until you have achieved the maximum tilling depth you desire. Faster engine speeds may be desirable when making final passes  
through the seedbed or when cultivating. Selection of the correct engine speed, in relation to the tilling depth, will ensure a sufficient  
power level to do the job without causing the engine to labor.  
Let the Tiller Do the Work  
Avoid Making Footprints  
Avoid Tilling Soggy, Wet Soil  
While tilling, relax and let the wheels pull  
the tiller along while the tines do the dig-  
ging. Walk on the side that is not yet fin-  
ished (to avoid making footprints in the  
freshly tilled soil) and lightly, but securely  
grip the handlebar with just one hand.  
Tilling wet soil often results in large, hard  
clumps of soil that can interfere with  
planting. If time permits, wait a day or two  
after heavy rains to allow the soil to dry  
before tilling. Test soil by squeezing it into  
a ball. If it compresses too easily, it is too  
wet to till.  
Whenever possible, walk on the untilled  
side of the unit to avoid making footprints  
in your freshly tilled or cultivated soil.  
Footprints cause soil compaction that can  
hamper root penetration and contribute to  
soil erosion. They can also “plant”  
unwanted weed seeds back into the  
freshly tilled ground.  
Preparing Seedbeds  
• When preparing a seedbed, go over the same path twice in the first row, then  
overlap one-half the tiller width on the rest of the passes (see Fig.  
4-5). When finished in one direction, make a second pass at a right angle, as  
shown in Fig. 4-6. Overlap each pass for best results (in very hard ground, it  
may take three or four passes to thoroughly pulverize the soil.)  
Fig. 4-5  
Fig. 4-6  
Cultivating  
• If the garden size will not permit  
lengthwise and then crosswise

With planning, you can allow  
enough room between  
rows to cultivate (see Fig.

tilling, then overlap the first passes  
by one-half a tiller width, followed  
by successive passes at one-  
quarter width (see Fig. 4-7).

TILLING TIPS & TECHNIQUES (cont.)  
Power Composting  
Power composting simply means tilling under and burying in the soil all manner of  
organic matter such as crop residues, leaves, grass clippings and cover crops. This  
material will decompose during the non-growing season and add important natural nutri-  
ents to the soil.  
WARNING  
When power composting, do not keep  
the Depth Regulator Lever at a deep  
setting if the tiller jumps or bucks.  
The first place to begin is with crop residues such as leftover vines, stalks, stems and  
roots. Power compost these crop residues as soon as they finish bearing. The sooner  
this is done, the better, as tender green matter is easier to till under. Use the deepest  
depth regulator setting possible without causing the engine to labor or the tiller to jump  
ahead.  
If jumping or bucking occurs, move the  
Depth Regulator Lever down to a  
shallow setting and then slowly  
increase the tilling depth on later  
passes.  
Standing cornstalks of reasonable height can be power composted. Pushing over (but  
not uprooting) cornstalks will often make it easier to chop up the stalks. Keep the tines  
clear of excessive tangling by “fishtailing” or frequently using reverse. Make several  
passes, then return a few days later to finish off any remaining stubble.  
Failure to follow this warning could  
result in personal injury.  
After tilling under crop residues, add more organic matter such as leaves, grass clippings and even kitchen scraps. When tilled into the  
soil, this organic matter will decompose and add even more important nutrients to the soil.  
After power composting, you may want to plant a “green manure” cover crop to protect the soil during the off-season. You simply  
grow a crop of clover, alfalfa, buckwheat, peas, beans, rye grass, grain, or kale and then till it into the soil prior to the planting season.  
Tilling On Slopes  
Read the following recommendations before tilling on slopes:  
WARNING  
Do not operate tiller on a slope too  
steep for safe operation. Till slowly  
and be sure you have good footing.  
If you must garden on a moderate slope, please follow two very important  
guidelines:  
1. Till only on moderate slopes, never on steep ground where footing is difficult  
(review safety rules in Section 1: Safety of this manual).  
Never permit tiller to freewheel down  
slopes. Failure to follow this warning  
could result in personal injury.  
2. We recommend tilling up and down slopes rather than terracing. Tilling vertically  
on a slope allows maximum planting area and also leaves room for cultivating.  
IMPORTANT: When tilling on slopes, be sure the correct oil level is maintained in  
the engine (check every one-half hour of operation). The incline of the slope will  
cause the oil to slant away from its normal level and this can starve engine parts of  
required lubrication. Keep the motor oil level at the full point at all times!  
Tilling Across Slopes Without Using  
Terraces (Horizontal Tilling)  
• If vertical or terracing gardening aren’t  
practical for you, then you can till laterally  
across a slope. We don’t recommend this  
method as it can create unsure footing and  
invites soil erosion.  
Tilling Up and Down Slopes (Vertical Tilling)  
• To keep soil erosion to a minimum, be sure to add enough organic matter to the  
soil so that it has good moisture-holding texture and try to avoid leaving footprints  
or wheel marks.  
• As in terrace gardening, start at the top of  
the slope and overlap the first pass by half  
the width of the tiller. For added stability of  
the tiller, always keep the uphill wheel in the  
soft, newly tilled soil.  
• When tilling vertically, try to make the first pass uphill as the tiller digs more  
deeply going uphill than it does downhill. In soft soil or weeds, you may have to  
lift the handlebars slightly while going uphill. When going downhill, overlap the  
first pass by about one-half the width of the tiller.  
Terrace Gardening  
• When a slope is too steep or too short for vertical tilling, it may be necessary to till across the slope and create terraced rows. Ter-  
races are rows that are cut into the side of a slope, creating a narrow, but flat area on which to plant.  
• On a long slope, you can make several terraces, one below the other.  
• Terraces should be only 2-to-3 feet wide. Digging too far into the side of the slope will expose poor subsoil that is unproductive for  
plants.

• Each succeeding lower terrace is started by walking below the terrace you’re  
preparing. For added stability of the tiller, always keep the uphill wheel in the soft,  
newly tilled soil. Do not till the last 12" or more of the downhill outside edge of each  
terrace. This untilled strip helps prevents the terraces from breaking apart and  
washing downhill. It also provides a walking path between rows.

Clearing the Tines  
The tines have a self-clearing action which eliminates most tangling of debris in  
the tines. However, occasionally dry grass, stringy stalks or tough vines may  
become tangled. Follow these procedures to help avoid tangling and to clean  
the tines, if necessary.  
WARNING  
Before clearing the tines by hand, stop the  
engine, allow all moving parts to stop and  
disconnect the spark plug wire. Remove the  
ignition key on electric start models.  
• To reduce tangling, set the depth regulator deep enough to get maximum  
“chopping” action as the tines chop the material against the ground. Also, try  
to till under crop residues or cover crops while they are green, moist and  
tender.  
Failure to follow this warning could result in  
personal injury.  
• While power composting, try swaying the handlebars from side to side (about  
6" to 12"). This “fishtailing” action often clears the tines of debris.  
• It may be necessary to remove the debris by hand (a pocket knife will help you  
to cut away the material). Be sure to stop the engine and disconnect the spark  
plug wire before clearing the tines by hand.  
• Use sturdy ramps and manually (engine

and any handlers. The ramps should pro-  
vide good traction to prevent slipping;  
they should have side rails to guide the  
tiller along the ramps; and they should  
have a locking device to secure them to  
the vehicle.  
• Place wooden blocks on the downhill  
side of the wheels if you need to stop the  
tiller from rolling down the ramp. Also,  
use the blocks to temporarily keep the  
tiller in place on the ramps (if neces-  
sary), and to chock the wheels in place  
after the tiller is in the vehicle.  
However, if you must load or unload the  
tiller, follow the guidelines given next.  
• The handlers should wear sturdy footwear  
that will help to prevent slipping.  
• Before loading or unloading, stop the  
engine, wait for all parts to stop moving,  
disconnect the spark plug wire and let  
the engine and muffler cool.

If a cover is leaking, check for loose  
screws. If the screws are tight, a new  
gasket or oil seal may be required.  
TILLER LUBRICATION  
After every 10 operating hours, oil or  
grease the lubrication points shown in  
Figure 5-1 and described below.  
WARNING  
Before inspecting, cleaning or  
servicing the machine, shut off engine,  
wait for all moving parts to come to a  
complete stop, disconnect spark plug  
wire and move wire away from spark  
plug. Remove ignition key on electric  
start models.  
If the leak is from around a shaft and oil  
seal, the oil seal probably needs to be  
replaced. See your authorized dealer or  
contact the factory for service or advice.  
Use clean lubricating oil (#30 weight  
motor oil is suitable) and clean general  
purpose grease (grease containing a metal  
lubricant is preferred, if available).  
IMPORTANT: Never operate the tiller if the  
transmission is low on oil. Check the oil  
level after every 30 hours of operation and  
whenever there is any oil leakage.  
• Remove the wheels, clean the wheel  
shaft (A, Fig. 5-1) and apply a thin  
coating of grease to the wheel shaft.  
Failure to follow these instructions can  
result in serious personal injury or prop-  
erty damage.  
• Grease the back, front and sides of the  
depth regulator lever (B, Fig. 5-1).  
CHECK HARDWARE  
Check for loose or missing hardware after  
every 10 operating hours and tighten or  
replace (as needed) before reusing tiller  
• Remove the tines and clean the tine shaft  
(C, Fig. 5-1). Use a file or sandpaper to  
gently remove any rust, burrs or rough  
spots (especially around holes in shaft).  
Apply grease to ends of shaft before  
installing tines.  
Be sure to check the screws underneath  
the tiller hood that secure the transmission  
cover and the Depth Regulator Lever to the  
transmission.

recommendations.  
1. Check the gear oil level when the trans-  
mission is cool. Gear oil will expand in  
warm operating temperatures and this  
expansion will provide an incorrect oil  
level reading.  
8 - Whichever time interval occurs first.  
9 - Change after first 2 hours of break-in  
operation.  
CHECK FOR OIL LEAKS  
Before each use, check the tiller for signs  
of an oil leak – usually a dirty, oily accu-  
mulation either on the unit or on the floor.  
2. With the tiller on level ground, pull the  
Depth Regulator Lever all the way up.  
A little seepage around a cover or an oil  
seal is usually not a cause for alarm. How-  
ever, if the oil drips overnight, then imme-  
diate attention is needed. Ignoring an oil  
leak can result in severe transmission  
damage!  
3. Remove the oil fill plug (A, Fig. 5-2)  
from the transmission housing and look  
inside the oil fill hole to locate the main  
drive shaft situated below the hole.

Section 5: Maintenance  
WARNING  
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to  
come to a complete stop, disconnect spark plug wire and move wire away from spark plug.  
Failure to follow these instructions can result in serious personal injury or property damage.  
4. The gear oil level is correct if the gear  
oil is approximately halfway up the side of  
the main drive shaft.  
B. To Drain the Transmission Gear Oil:  
BOLO TINES  
The transmission gear oil does not need to  
be changed unless it has been contami-  
nated with dirt, sand or metal particles.  
The bolo tines will wear with use and  
should be inspected at the beginning of  
each tilling season and after every 30  
operating hours. The tines can be  
replaced either individually or as a com-  
plete set. See the Parts List pages for tine  
identification and part numbers.  
5. If the gear oil level is low, add gear oil  
as described next. If the gear oil level is  
okay, securely replace the oil fill plug.  
1. Drain gasoline from the fuel tank or run  
the engine until the fuel tank is empty. See  
“DANGER” statement below.  
IMPORTANT: Do not operate the tiller if  
the gear oil level is low. Doing so will  
result in severe damage to the transmis-  
sion components.  
DANGER  
A. Tine Inspection:  
Gasoline is highly flammable and its  
vapors are explosive. Follow these  
safety practices to prevent personal  
injury or property damage from fire or  
explosion.  
With use, the tines will become shorter,  
narrower and pointed. Badly worn tines  
will result in a loss of tilling depth, and  
reduced effectiveness when chopping up  
and turning under organic matter.  
• Allow the engine and muffler to cool  
for at least two minutes before  
draining the tiller’s gasoline tank.  
B. Removing/Installing a Single Tine:  
B
1. With the engine shut off and the spark  
plug wire disconnected, remove the two  
screws (A, Figure 5-3) and locknuts (B)  
that attach a single tine to a tine holder. If  
needed, use penetrating oil on the nuts.  
• Do not allow open flames, sparks,  
matches or smoking in the area.  
• Wipe away spills and push tiller away  
from spilled fuel.  
A
B
• Use only an approved fuel container  
and store it safely out of the reach of  
children.  
2. When installing a single tine, be sure to  
position it so that its cutting edge (sharp)  
will enter the soil first as the tiller moves  
forward.  
Figure 5-2: Remove oil fill plug (A) to check  
gear oil level and to add gear oil. Remove  
four cover screws (B) to drain gear oil.  
• Do not store gasoline in an area where  
its vapors could reach an open flame  
or spark, or where ignition sources are  
present (such as hot water and space  
heaters, furnaces, clothes dryers,  
stoves, electric motors, etc.).  
C. Removing/Installing a Tine Assembly:  
1. A tine assembly consists of eight tines  
mounted on a tine holder.  
6. If adding only a few ounces of gear oil,  
use API rated GL-4 or GL-5 gear oil having  
a viscosity of SAE 140, SAE 85W-140 or  
SAE 80W-90. If refilling an empty trans-  
mission, use only GL-4 gear oil having a  
viscosity of SAE 85W-140 or SAE 140.  
2. If removing both tine assemblies, mark  
them “left” and “right” before removal.  
Remove the screw (C, Figure 5-3) and  
locknut (D) that secure the tine assembly  
to the tine shaft. If necessary, use a  
rubber mallet to tap the tine assembly out-  
ward off the shaft.  
2. Drain the oil from the engine.  
3. Remove four screws (B, Figure 5-2) and  
remove transmission cover and gasket.  
IMPORTANT: Do not use automatic trans-  
mission fluid or motor oil in the transmis-  
sion.  
4. Remove the left-side wheel.  
5. Tilt the left-side wheel shaft into a drain  
pan and allow the gear oil to drain through  
the top of the transmission.  
3. Before reinstalling the tine assembly,  
inspect the tine shaft for rust, rough spots  
or burrs. Lightly file or sand, as needed.  
Apply a thin coat of grease to the shaft.  
7. While checking frequently to avoid  
overfilling, slowly add gear oil into the oil  
fill hole until it reaches the halfway point  
on the drive shaft.  
6. Reinstall the wheel.  
7. Install a new gasket (do not reuse old  
gasket) and reinstall the transmission  
cover.  
4. Install each tine assembly so that the  
cutting (sharp) edge of the tines will enter  
the soil first when the tiller moves  
forward. Secure the tine assembly to the  
tine shaft using the screw and locknut  
previously removed.  
8. Securely replace the oil fill plug.  
8. Refill the transmission using GL-4 gear  
oil (SAE 85W-140 or SAE 140).  
9. Refill the engine with motor oil and  
replenish the fuel tank with gasoline.

Section 5: Maintenance  
WARNING  
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to  
come to a complete stop, disconnect spark plug wire and move wire away from spark plug.  
Failure to follow these instructions can result in serious personal injury or property damage.  
FORWARD CLUTCH  
BAIL ADJUSTMENT  
ENGINE OIL SERVICE  
SPARK PLUG SERVICE  
Check the engine oil level before each use  
and after every 5 hours of continuous  
operation. Running the engine when it is  
low on oil will quickly ruin the engine.  
Inspect and clean or replace the spark  
plug after every 100 operating hours or  
annually. Refer to the Engine Owner’s  
Manual for spark plug service instructions.  
If the Forward Clutch Bail does not func-  
tion properly, first check that the forward  
drive belt is adjusted properly (see  
Checking and Adjusting Forward Drive  
Belt Tension). If this fails to correct the  
problem, contact your authorized dealer  
for service advice.  
It is recommended that you change the  
motor oil after every 10 hours of operation resistor spark plugs to suppress ignition  
and even sooner when operating in  
extremely dirty or dusty conditions. Refer  
to the Engine Owner’s Manual for detailed  
service instructions.  
In some areas, local law requires using  
signals. If the engine was originally  
equipped with a resistor spark plug, use  
the same type for replacement.  
ENGINE CLEANING  
SPARK ARRESTER SCREEN  
SERVICE  
If the engine muffler is equipped with a  
spark arrester screen, remove and clean it  
according to the service intervals and  
instructions in the Engine Owner’s  
Manual.  
Keeping the engine clean will help to  
ensure smooth operation and prevent  
damage from overheating. Refer to the  
Engine Owner’s Manual for engine  
cleaning service intervals and instructions.  
Be sure that the muffler is cool before ser-  
vicing the engine.  
A. To Check the Engine Oil Level:  
1. Park the tiller on a level area and shut  
off the engine.  
2. Level the engine (use the Depth Regu-  
lator Lever to adjust the engine angle).  
3. Clean around the oil dipstick or oil fill  
tube (whichever applies) to prevent dirt  
from falling into the crankcase.  
AIR CLEANER SERVICE  
THROTTLE LEVER ADJUSTMENT  
The air cleaner filters dirt and dust out of  
the air before it enters the carburetor.  
Operating the engine with a dirty, clogged  
air filter can cause poor performance and  
damage to the engine. Never operate the  
engine without the air cleaner installed.  
Inspect and service the air cleaner more  
often if operating in very dusty or dirty  
conditions. Refer to the Engine Owner’s  
Manual for air cleaner service intervals  
and instructions.  
If the engine does not respond to various  
throttle lever settings, refer to the Engine  
Owner’s Manual for service information or  
contact your local authorized engine  
dealer.  
4. On engines with an oil fill tube, remove  
the fill cap and add oil (if required) until it  
reaches the top of the fill tube. Reinstall  
the fill cap.  
5. On engines with a dipstick, remove it  
and wipe it clean. Reinsert the dipstick,  
tighten it securely, and remove it. Add oil  
as needed to bring the level up to the FULL  
mark. Wipe dipstick clean each time oil  
level is checked. Do not overfill. Tighten  
dipstick securely.  
WARNING  
Operators shall not tamper with the  
engine governor settings on the  
machine; the governor controls the max-  
imum safe operating speed to protect  
the engine and all moving parts from
