TILLING TIPS & TECHNIQUES
Tilling Depths
A.
WAKNiNG:
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.
• Avoid pushing 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
helping to hold the tiller back, the tines will attempt to propel the tiller - often causing the tiller
to skip rapidly across the ground. (Sometimes, slight downward pressure on the handlebars
will help getthrough a particularly tough section of sod or unbroken ground, but in most cases
this won’t be necessary.)
• Avoid trying to dig too deeply too quickly, especially when busting sod or when tilling soil that
hasn’t been tilled for some time. Use shallow depth regulator settings (only an inch or two
deep) for the first passes through the soil. With each succeeding pass, dig another inch or two
deeper. (Watering the 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.)
• When cultivating (breaking up surface soil around plants to destroy weeds, see Fig. 4-9), adjust the tines to dig only 1" to 2“ deep. Using
shallow tilling depths helps prevent injury to 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.)
Choosing Correct Wheel & Tine Speeds With experience, you will find the “just right” tilling depth and tilling speed combination
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 slowest possible speed...at least
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.
Let the Tiller Do the Work
While tilling, relax and let the wheels pull the
tiller along while the tines do the digging.
Walk on the side that is not yet finished (to
avoid making footprints in the freshly tilled
soil) and lightly, but securely grip the han­
dlebar with just one hand.
Avoid Making Footprints
Whenever possible, walk on the untilled
side of the unit to avoid making footprints in
your freshly tilled or cultivated soil. Foot­
prints cause soil compaction that can ham­
per root penetration and contribute to soil
erosion. They can also “plant” unwanted
weed seeds back into the freshly tilled
ground.
Avoid Tilling Soggy, Wet Soil
Tilling wet soil often results in large, hard
clumps of soil that can interfere with plant­
ing. If time permits, wait a day or two after
heavy rains to allow the soil to dry before
tilling. Test soil by squeezing it into a ball, if
it compresses too easily, it is too wet to till.
Preparing Seedbeds
•When preparing a seedbed, go over the same path twice in the first row, then over­
lap one-half the tiller width on the rest of the passes (see Fig. 6). When finished in
one direction, make a second pass at a right angle, as shown in Fig. 4-7. Overlap
each pass for best results (in very hard ground, it may take three or four passes to
thoroughly pulverize the soil.)
• If the garden size will not permit lengthwise and then crosswise tilling, then over­
lap the first passes by one-half a tiller
width, followed by successive passes
at one-quarter width (see Fig. 4-8).

Cultivating
With planning, you can
allow enough room
between rows to cultivate
(see Fig. 4-9). Leave room
for the hood width,
plus enough extra
room for future plant
growth.
