CLEARING THE TINES
WARNING
Before clearing the tines by hand, stop the engine, allow all moving
parts to stop and disconnect the spark plug wire. Failure to follow this
warning could result in personal injury.
The tines have a self-clearing action which eliminates most of the
tangling of debris. However, occasionally dry grass, stringy stalks or
tough vines may become tangled. Follow these procedures to help
avoid tangling and to clear the tines, if necessary.
Try to till under crop residues or cover crops while they are green,
moist and tender.
While tilling, try swaying the handlebars from side to side (about
6" to 12"). This "fishtailing" action often clears the tines of debris.
TILLING TIPS & TECHNIQUES
WARNING
Before tilling, contact your telephone 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.
Tilling Depth
This is a FRT (forward-rotating tine) tiller. When the forward tine
engagement lever is pressed against the handle the tines rotate
forward. This creates an "uppercut" tine action which digs deeply,
uprooting soil and weeds. Don't overload the engine, but dig as
deeply as possible on each pass.
When cultivating (breaking up the surface soil around the plants to
destroy weeds, See Figure 16), try to have the tines only dig 1" to
2" deep. Using the shallow tilling depth helps prevent injury to the
plants whose roots often grow close to the surface. If needed, lift
up on the handlebars 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.) Watering the garden 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.
OPERATION
Figure 16
Choosing the Correct Tine Speed
With experience, you will find the tilling depth and tilling speed combina-
tion 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 slow-
est possible speed 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.
Suggested Tilling Patterns
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 Figure 17.
When finished in one direction, make a second pass at a right
angle, See Figure 18. Overlap each pass for the best results (in
very hard ground, it may take three or four passes to thoroughly
pulverize the soil).
