OPERATING PROCEDURE
It
is
recommended
that
rear
wheel
weights
be
used
on
all
tractors.
Front
wheel
weights
are
also
recom-
mended.
Never
dismount
from
1ractor
without
disengaging
clutch
and
setting
tractor
park
brake.
Always
stop
the
engine
to
remove
rocks
or
debris
from
the
tines.
For
best
performance
the
tiller
should
be
operated
with
the
engine
set
at
full
throttle.
The
ground
speed
of
the
tractor
should
then
be
regulated
to
match
soil
conditions.
In
hard,
compacted
soils
or
clay
it
may
be
necessary
10
go
slowly
in
order
to
obtain
soil
penetration.
Better
penetration
can
be
obtained
by
removing
the
outer
two
tines
which
reduces
the
tilling
width
to
30
inches.
For
best
performance
depending
on
ground
cover
it
may
be
necessary
to
till
area
twice"
One
operation
being
90°
to
the
other
if
terrain
permits
or
by
over-
lapping.
When
tilling in
sod
or
gumbo
soils
the
tiller will
have
a
tendency
to
push
the
tractor..
Wheel
weights
will
help
to
counteract
this.
However,
it
may
also
be
advisable
to
control
the
depth
of
soil
penetration
with
the
Height-A-Ma1ic lift
lever
or
with
the
hydraulic
control
attachment.
Do
not
over-till
the
soil
or
pulverize
it. Soil tilled too
finely
will not
absorb
moisture.
It
will
cause
puddling
and
water
run-off"
In
addition
the
soil will
become
compacted
more
readily.

touching
the
ground.
Remove
the
pipe
plug
on
the
