yoke back
Attach the wheel yoke so that the wheels are toward the rear (closest
to depth stake) for deep tilling and cultivating by removing the clevis
pin and cotter pin. See Figure 15.
Depth Stake
The depth stake acts as a brake for the tiller and controls the depth
and speed at which the machine will operate. Remove the clevis pin
and hairpin clip to raise or lower the depth stake. See Figure 16.
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 knob, move the handle to the desired height
and retighten the handle knob. See Figure 17.
clearing The TineS
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
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 18), 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.
choosing the correct Tine Speed
With experience, you will find the 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 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.
