TILLING TILLING
HINTS
Soil
conditions
are
important
for
proper
tilling'
Thetines
will
not
readily
penetrate
dry,
hardsoil.
This maycontribute
to excessive
bounce
and
diff
icult
handling
of
the
tiller.
Hardsoil
should
be
moistened
prior
totilling.
Extremely
wetsoil
willcause
soil
to ball
up or
clumD.
When
tilling
inthe
Fall,
all
vines
and
long
grass
should
be removed.
This
will prevent
vines
form
wrapping
around
the
tine
shaft
which
slows
tilling
operation.
Thebest
method
will be determined
by the soil
condition.
In some soils, the desired
depth is
obtained
the firsttime over
the garden.
In other
soils,
the
desired
depth
isobtained
by
going
over
the
garden
two or three
times.
Inthe latter
case,
the drag stake should be raised before each
succeeding
pass over the garden, and passes
should
be
made
across
the
length
and
width
ofthe
garden
alternately.
Rocks
which are turned up
shouldberemoved
from the garden
area.
Handle
Pressure:
Further
control
of tilling
depth
and travel
speed
can be obtained
by variation
of
pressure
on
the
handles.
Whenusingthe drag
stake
a downward
pressure
on the handles
will increase
the working
depth
and reduce the forward speed. An upward
pressure
on the handles
will reduce
theworking
depth
and
increase
the
forward
speed'
Thetype
of
soil and working
conditions
will determine
the
actual
setting
ofthe
