WARNING
ENGINE AND SURROUNDING PARTS BECOME
EXTREMELY HOT DURING NORMAL USE. TEMPERATURE
OF MUFFLER AND NEARBY AREAS MAY EXCEED 150° F.
THESE AREAS WILL CAUSE SERIOUS BURN INJURIES IF
TOUCHED BEFORE THE ENGINE HAS COOLED.
Start-Up
The controls required to start and run the rototiller are located
on the engine and are the choke lever, throttle lever and On/
O switch. The choke lever is marked on one end with CHOKE
and on the other with RUN. The throttle lever is marked on
one end with a SLOW icon and on the other with a FAST icon.
A more detailed description of engine operation and all related
precautions and procedures can be found in the engine
manufacturer’s manual that accompanies each tiller.
Cold starts:
1. Turn ON/OFF switch to the ON position.
2. Move choke lever to CHOKE position.
3. Move throttle lever to half way between SLOW and
FAST.
4. Pull starting rope out slowly one time and allow to return
normally.
5. Pull starting rope out rapidly, and allow rope to return
normally. Repeat until engine starts.
6. When engine starts, gradually move choke lever to RUN
position and move throttle lever to FAST position for
tilling.
Restarting a warm engine:
Restarting an engine that is already warm from previous
running does not normally require use of the choke.
1. Move throttle lever to half way between SLOW and
FAST.
2. Pull starting rope out rapidly, and allow rope to return
normally. Repeat until engine starts.
3. Adjust throttle speed to FAST position for tilling.
Operator’s Manual
CRT Rototiller
Idle Speed:
Use the SLOW position or a position between SLOW and FAST
on the throttle lever to reduce stress on the engine when
tilling is not being performed. Lowering the engine speed to
“idle” will help extend the life of the motor, as well as conserve
fuel and reduce the noise level of the equipment.
Operating Speed:
For tilling, set the throttle lever to the FAST position.
CAUTION
DO NOT USE THE CHOKE TO STOP ENGINE. IF CHOKE
LEVER IS PLACED IN CHOKE POSITION WHILE ENGINE
IS RUNNING, BACKFIRE OR ENGINE DAMAGE MAY
OCCUR.
Shutting Down:
To stop the engine at any time, move the On/O switch to
the OFF position. To stop wheels and tines at any time release
drive safety control levers to NEUTRAL position. SEE FIGURES
6&7.

IMPORTANT
PRACTICE OPERATING THE CONTROLS AND TILLER
WITH TINES OUT OF GROUND BEFORE BEGINNING TO
TILL. IT IS IMPORTANT THAT YOU KNOW HOW TO USE
THE TILLER PROPERLY, KEEP CONTROL AT ALL TIMES,
STOP THE TINES AND WHEELS FROM TURNING,
AND STOP THE ENGINE IF NECESSARY. IF YOU DO
NOT KNOW HOW TO DO THESE THINGS, READ THE
CONTROLS, ADJUSTMENTS AND SAFETY SECTIONS
BEFORE PROCEEDING.
WARNING
ALWAYS MAINTAIN CONTROL OF YOUR TILLER. ONLY
OPERATE TILLER IN SOIL CONDITIONS THAT ARE
CONDUCIVE TO MAINTAINING CONTROL OF THE
TILLER. DO NOT OPERATE TILLER IN CONDITIONS
THAT CONTAIN ROCKS, FOREIGN OBJECTS, OR
ANY OTHER MATERIAL THAT IS NOT SOIL. IF YOUR
TILLER BUMPS, JERKS OR LURCHES, LET GO OF THE
HANDLE BARS AND THE DRIVE CONTROL LEVERS
IMMEDIATELY SO THAT THE TINES AND WHEELS STOP
TURNING.
IMMEDIATELY RELEASE THE DRIVE CONTROL LEVER
IF THE TINES JAM OR YOU STRIKE A FOREIGN OBJECT.
WITH DRIVE CONTROL LEVER 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 Rototiller
Tilling:
1. Adjust the depth regulator lever to desired tilling depth.
NOTE: Raise depth regulator lever up one hole at a time,
testing tiller operation after each raise. Raising
depth regulator lever too high can result in loss of
control of tiller!
2. Move the throttle control to FAST position.
3. Place the tiller in FORWARD by pulling the drive safety
control
Tilling tips:
The key to successful tilling is to begin with a shallow cut on
the rst 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 lock pin in the highest
hole of the depth regulator lever (SEE OPERATION
SECTION). This will allow for shallow tilling. With the
depth regulator lever 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 depth
regulator lever by placing the lock pin in a higher
hole. This will allow for shallower tilling. Hold rmly to
the handle bars to control sudden lurches.
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 lock 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.

Check Tiller Transmission Grease:
Check the grease level annually. To check the grease level:
1. Cut out one of the cardboard stencils on page 27 of this
manual. Take that dipstick cut-out and glue/tape it to a
piece of cardboard cut out to match the stencil.
2. Tiller must rst be run for approximately 30 minutes to
warm up grease for a proper measurement. Once warm
let sit 5 minutes to allow grease to settle.
3. Move tiller to level ground, making sure the engine
mount is level.
4. Remove the gear case dipstick located between the
handle bar mounts and the engine mount.
SEE FIGURE 15
5. Insert the dipstick cut-out created in step 1 into the hole
in the engine mount so the top square is resting on the
cover plate. SEE FIGURE 16
6. Remove the dipstick cut-out and check grease level.
If level is in the bottom ADD area or not present, add
grease in 200ml increments until grease level reaches a
proper level reading (between 1” - 1 3/4” down from top
of ll hole). DO NOT OVERFILL. The slashed, acceptable
grease level area on the dipstick cut-out has a 200ml
range.
NOTE: The front wheel transmission and rear tine
transmission share a common reservoir.
Recommended grease is Mystic 00, or equivalent,
transmission grease. Oil must have an API E.P (extreme pressure) rating of GL4 or lower.
Higher E.P. rating (ie - GL5, GL6 etc) will cause
the bronze components to soften. For partial
ll-ups ( a few ozs or less) use SAE 140W or 85W
gear oil or SAE 80W-90 weight gear oil with a API
rating of GL4 or GL5. When replacing grease, the
tiller transmission holds 18-22 ounces. DO NOT
OVERFILL.
