IMPORTANT
The right and left sides of
your rototiller are determined from the operating position as you face the direction
of forward travel.
Engine is shipped from factory
without oil. You must add engine oil before starting engine.
• Never attempt to make any adjustments while the engine is
running.
Operation
• Never operate the tiller without guards, covers, and hoods in
place.
• Never start the engine or operate the tiller with the wheels
in the free-wheel position. Make sure the wheel lock pins
are engaged through the wheel hubs and wheel axle. The
wheels act as a brake to keep the tiller at a controlled speed.
Disengage wheel lock pins to permit free-wheeling only when
engine is stopped.
• Keep hands, feet, and clothing away from rotating parts. Keep
clear of tiller tines at all times.
• Tines and wheels rotate when tiller is engaged in forward or
reverse-- in forward, tines and wheels rotate when the drive
safety control lever, labeled “FORWARD”, is pulled toward the
handlebar. In reverse, wheels and tines rotate when the drive
safety control lever, labeled “REVERSE”, is pulled toward
the handlebar. Releasing the drive safety control levers to the
neutral position stops the wheels and tines. Do not operate
both drive safety control levers at the same time.
• Be extremely cautious when operating in reverse. Take extra
care to avoid slipping or falling, and keep hands and feet clear
of tines.
• Use extreme caution when operating on or crossing gravel
drives, walks, or roads. Stay alert for hidden hazards or traffic.
• After striking a foreign object, stop the engine, remove the
wire from the spark plug, thoroughly inspect the tiller for
any damage, and repair the damage before restarting and
operating the tiller.
• If vegetation clogs the tines, raise the handlebars to elevate
the tines, and run the tiller in reverse. If this does not clean
clogged vegetation from the tines, STOP THE ENGINE AND
DISCONNECT THE SPARK PLUG WIRE before removing
vegetation by hand.
• Engine muffler will be hot from operation. Do not touch it with
bare skin or a severe burn may result.
• If the unit should start to vibrate abnormally, stop the engine
and check immediately for the cause. Vibration is generally a
warning of trouble.
• Do not run the engine indoors; exhaust fumes are deadly.
• Never allow bystanders near the unit.
• Use only attachments and accessories approved by the
manufacturer of the tiller.
• Never operate the tiller without good visibility or light.
• Be careful when tilling in hard ground. The tines may catch
in the ground and propel the tiller backward. If this occurs, let
go of the handlebars and do not restrain the machine.
• Take all possible precautions when leaving the machine
unattended. Disengage all control levers, stop the engine,
wait for all moving parts to stop, and make certain guards and
shields are in place.
• When leaving the operating position for any reason:
- shut off the engine.
- wait for all moving parts to stop.
Maintenance and storage
• Keep machine, attachments, and accessories in safe working
condition.
• Check shear bolts, engine mounting bolts, and other bolts at
frequent intervals for proper tightness to be sure the equipment
is in safe working condition.
• To prevent accidental starting, always disconnect and secure
the spark plug wire from the spark plug before performing tiller
maintenance.
• Never run the engine indoors. Exhaust fumes are deadly.
• Always allow muffler to cool before filling fuel tank.
• Never store equipment with gasoline in the tank inside a closed
building where fumes may reach an open flame or spark. Allow
the engine to cool before storing in any building.
• Always refer to the operator’s guide instructions for important
details if the tiller is to be stored for an extended period.
• Add a fuel stabilizer to gas tank and run for 10-15 minutes to
prevent fuel from gumming up during an extended storage
period.
• Do not overload the machine capacity by attempting to till too
deep at too fast a rate.
• Never operate the machine at high transport speeds on
slippery surfaces. Look behind and use care when backing.

Tilling Tips
The key to successful tilling is to begin with a shallow cut on the first
pass, and then work an inch or two deeper on each successive pass.
• Tilling depth will vary with ground conditions.
• When beginning to till in unbroken ground or in extremely hard
soil, set the detent pin in the highest hole of the drag stake (follow
instructions under Tilling section). This will allow for shallow tilling.
With the drag stake in this position, make several light passes
over the area to be tilled. Reset for deeper depths with successive
passes.
! WARNING
Extreme caution must be taken in selecting tilling depth. If you attempt to till
too deeply for soil conditions, that is,
with the drag stake in too high a position,
loss of control could result.
If removing material from the tines by
hand, stop engine and remove spark plug
wire first.
• If tiller jumps or skids uncontrollably, lower the drag stake by placing
the detent pin in a higher hole. This will allow for shallower tilling.
Hold firmly to the handlebars to control sudden lurches.
• If weeds, tall grasses, vines, or other materials clog or jam the
tines, reverse the tiller to unwind vegetation.
Immediately release the drive control levers if the tines jam or you
strike a foreign object. With drive control levers in neutral position,
push throttle control to stop position to stop the engine. Disengage
the spark plug wire. When tines have stopped, remove foreign objects
and check for damage.
Cultivating Tips
If you plan to use your tiller for cultivating:
• Plant rows on 20" - 22" centers for ease of turning.
• Set the depth regulator lever with the detent pin in one of the higher
holes. This will allow for shallow cultivation necessary to turn over
weeds, and break up and aerate the soil.

2. Change oil after first 5-8 hours of operation. Change oil while
engine is warm. Refill with new oil of recommended grade.
4.Check spark plug yearly or every 100 hours of operation.
5. Service air cleaner.
6. Keep engine and parts clean.
7.Check engine and equipment often for loose nuts and bolts, keep
these items tightened.
Check or Fill Engine Crankcase
1. Add oil according to engine manual. Do not overfill. Use a
clean, high quality detergent oil. Use no special additives with
recommended oils. Do not mix oil with gasoline. Oil level must
be full. Check the oil level by removing oil fill plug. Oil level should
be up to the bottom of the fill plug opening.
2. Always check oil level before starting engine. Refer to engine
manual for capacity and type of oil to use.
Check Tiller Transmission Grease
IMPORTANT
Engine is shipped from factory without
oil. You must add engine oil before
starting engine.
IMPORTANT
TILLER TRANSMISSION IS SHIPPED FROM
FACTORY WITH THE PROPER AMOUNT OF LIQUID
GREASE.
When replacing grease, the tiller
transmission holds 18-22 ounces. DO NOT
OVERFILL.
gear case
dipstick
Check the grease level annually. To check the grease level:
1. Move tiller to level ground.
2. Remove grease level dipstick located between the handlebar
mounts on the engine mount. Correct grease level is indicated
between the high and low levels on the dipstick.
transmission
cover plate
3. Replace grease level dipstick in the filler hole.
4. Note that the front wheel transmission and rear tine transmission
are one common reservoir. When you add to the front transmission,
you must wait a short period of time for the grease to flow rearward
and equalize in both front and rear. The dipstick will read correctly
on level ground for both gear units.
(Use Mystik 00, or equivalent, transmission grease.)
Check Tire Pressure
Recommended tire pressure is 20 PSI. If tires do not have equal
pressure, tiller will pull to one side.

Lubrication
Proper lubrication of moving mechanical parts is critical for proper
care and maintenance. Oil the moving parts at 10 hour intervals using
a 30 weight oil.
Clean Tine Axle Shaft
1. Turn off engine. Engine must be cool.
2. Remove spark plug wire and secure from spark plug.
! WARNING
Do not store tiller in an unventilated
area where fuel fumes may reach flame,
sparks, pilot lights or an ignited object.
Drain fuel outdoors away from any
ignition sources. Use only approved
fuel containers.
3. Tip the tiller forward. Block the tiller in position so that it rests on
the engine mount and the tines are exposed.
4. Remove all vegetation, string, wire, and other material that may
have accumulated on the axle between the inside set of tines and
the seal on the transmission housing.
5. Tip the tiller back to a level position.
6. Replace spark plug wire.

Prepare for Storage
Follow the steps below to prepare your tiller for storage. Read your
engine manual for detailed instructions on preparing the engine for
storage.
1. Protect wheels and axles from rust:
- Remove lockpin and slide wheel off hub.
-Coat the axles lightly with axle grease.
- Slide wheel back on hub and insert lock pin.
2. Drain fuel system completely following engine manufacturer’s
instructions or add fuel stabilizer to prevent fuel from gumming
up during extended storage period.
3. While engine is still warm, drain the oil from the engine. Refill with
fresh oil of the recommended grade.
4.Clean external surfaces, engine and cooling fan.
5. Remove spark plug, pour one ounce of SAE 30 oil into spark plug
hole.
6. Plug hole and pull starter cord slowly to distribute oil evenly in
cylinder head area.
7. Reinstall spark plug.
8. Transport unit to a suitable storage location. If you have chosen to
use a fuel stabilizer and have not drained the fuel system, follow all
safety instructions storage precautions in this manual to prevent the
possibility of fire from the ignition of gasoline fumes. Remember,
gasoline fumes can travel to distant sources of ignition and ignite,
causing risk of explosion and fire.
9. If there is any possibility of unauthorized use or tampering, remove
the spark plug and store it in a safe place before storing the rototiller
unit. Be sure to plug the spark plug hole to prevent foreign material
from entering.
