to the desired position and replace the wing nuts. Tighten securely.
See Figure 10.
ADJUSTING THE HANDLE HEIGHT
The handle should be adjusted so that when the tiller is digging 3-4”
into the soil, the handle falls to about waste-high. To adjust handle,

simply loosen the handle adjustment crank, move the handle to the
desired height and retighten the adjustment crank. See Figure 11.
CLEARING THE TINES
• The tines have a self-clearing action which eliminates most of the
tangling of debris. Flowever, occasionally dry grass, stringy stalks
or tough vines may become tangled. Follow these procedures to
help avoid tangling and to clear the tines, it necessary.
• To reduce tangling, set the depth regulator deep enough to get
maximum “chopping” action as the tines chop the material against
the ground. Also, try to till under crop residues or cover crops
while they are green, moist and tender.
AWARNING
Before tilling, contact your telephone or utilities company and inquire
it underground equipment or lines are used on your property. Do not
till near buried electric cables, telephone lines, pipes or hoses.
• 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
Tilling Depth
• This is a CRT (counter-rotating tine) tiller. As the wheels pull
forward, the tines rotate backward. 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
On later passes, the wheels may tend to spin in the soft dirt. Help
them along by lifting up slightly on the handlebar (one hand, palm
up, works most easily).
• Avoid the temptation to push down on the handlebars in an
attempt to force the tiller to dig deeper. Doing so takes the weight
off the powered wheels, causing them to lose traction. Without the
wheels to hold the tiller back, the tines will attempt to propel the
tiller backward, towards the operator.
• When cultivating (breaking up the surface soil around the plants
to destroy weeds. See Figure 12), adjust the tines to dig only 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
