1 . The
combination
hitch
can
be
used as either a single
strap
or
clevis hitch as shown in figures 1
and
2.
The bolt holes in the
hitch
have been offset vertically
so
the
hitch
can be turned over
and
bolted ·at
two
height locations
on
the tongue.This makes
it
possible
to
have four hitch heights
for
both
the single strap and
the
clevis
hitch. HITCH HEIGHT SHOULD
BE SET
SO
TONGUE OF DRILL IS
PARALLEL TO
THE
GROUND
WHEN DRILLING.
2 . The tongue jack makes it possible
to
raise or lower the hitch
as
need-
ed for tractor hook-up.
Always
return jack to its horizontal storage
position on top
of
tongue slide
before folding drill
(see
fig. 3 and
4).
3.
Once you have the hitch pin in place (1" DIA. MINIMUM SIZE PIN) and
the
jack
in storage position, you are ready
to
hook
up
your hydraulic hoses. You need a
dual
hydraulic system.
If
this is the first time you have had fluid
in
the
systems, you should use the following procedure:
a.
Hook Hydraulic hoses
to
tractor outlet.
b.
Loosen both connections on one cylinder.
c. Slowly work hydraulic lever
back
and forth.
d.
When fluid begins
to
come
out
of
one
hose, tighten that connection.
e.
When fluid begins
to
come
out
of
the
other
hose, tighten
that
connection.
f. Repeat above process
on
each cylinder.
g.
Check tractor hydraulic reservoir fluid level at this time. You will probably have
to
add some hydraulic flUid.
(See detailed drawings
of
hydraulic
system
in Parts Manual.)

If
wing
cylinders
do
not operate properly, clean
out
small orifice in fittings circled on wing cylinder illustration
(see fig.
5).
