c,. Fill fuel tank outdoors with extreme care. Never fill
fuel tank indoors.
d. Replace gasoline cap securely and clean up spilled
fuel before restarting.
• 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.
• 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.

detent pin in the bottom hole of the depth regulator
lever for deepest tilling.
BELT TENSION ADJUSTMENT
Proper belt tension is critical to good performance.
After 1/2 hour of operation, all cables may have to be
adjusted due to initial stretch. Thereafter, check tension
after every 2 hours of operation.
To increase belt tension:
1. Loosen upper jam nut. Turn nut up cable in 1/8”
increments.
2. Tighten lower jam nut.
3. Check adjustment.
This procedure can be repeated until conduit adjustment bolts are fully adjusted. If no more adjustment can
be made, belt may have to be replaced.

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.
• 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.
Operator's Manual
CRT Models 5040 and 6040E
WARNING
EXTREME CAUTION MUST BE TAKEN IN SE
LECTING 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.
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.
