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. Proper tension is achieved when the spring
compresses 6.4 mm (1/4”) when drive lever is engaged.
Tools Required for Assembly:
13 mm wrench
To increase belt tension:
1. Loosen upper jam nut. SEE FIGURE 8
2. Tighten the lower jam nut in 1/8” increments, making
sure not to over adjust the tension.
3. Check adjustment by measuring spring compression
when drive lever is engaged. (Proper spring compression
6.4 mm (1/4”))
4. When proper adjustment is achieved, tighten upper jam
nut.
This procedure can be repeated until conduit adjustment bolts
are fully adjusted. If no more adjustment can be made the belt
may need 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 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 firmly to
the handle bars to control sudden lurches.
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.
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.

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. FAILURE TO COMPLY WITH THIS SAFETY
REQUIREMENT CAN RESULT IN SERIOUS INJURY OR
