AUTOMATIC PICK UP HITCH
I tin hydraulically operated pick-up hitch installation,
available as a production
M|Mion
or accessory,
provides
a means whereby trailers, etc.. can be quickly
.tM.iched
to the
tractor
without It being necessary for the operator to leave the
I In- design of
the
auto-hitch is
such that
equipment
may be operated on the
normal 3-point linkage
without removing
the
auto-hitch
from the tractor.
Raising and lowering of the hitch hook is controlled by the standard hydraulic
id i
lever. A special device is incorporated in the hitch unit to mechanically
lock
it in the raised position.

1. Set the Position/Draft selector
lever
to Position Control.
2- Move the hydraulic lift main control lever to the fixed stop at the top of the
quadrant to take the weight of
the
hitch off
the
locking struts
(1
).
I
Pull
the release handle
(2)
(forwards
on the
Ford
2000 and 3000 tractors,
upwards on the Ford 4000 and 5000 tractors) while moving the hydraulic
lilt main control lever down the quadrant. Allow the spring loaded release
handle to return to its normal position
as
soon
as the
hitch arms
(3)
have
lowered sufficiently
for the
locking
lugs
(4)
to clear the locking struts.
A. Position the
hitch hook
directly
under
the eye of the drawbar of the trailed
equipment.
5, Move the main control lever slowly up the
quadrant
until the
hook engages
with the
eye.
Continue moving
the
main
control lever to the fixed stop at the
top of the quadrant to fully raise the hook, then drop the lever slightly to
allow the locking lugs on the hitch lifting arms to rest on the locking struts.
The downward load on the automatic pick-up hitch hook should not
exceed
3000
lbs
(1361 kg).
Adjustments (Ford 2000 and
3000)
'
Periodically check, with the lift arms in the fully raised position, the clearance
between hook and the drawbar
support assembly plate.

.
The
specified clearance is 1
/32
inch (0'8
mm) and if any adjustment should be
required turn the yokes on the lifting rods an equal amount until the correct gap
is
obtained
(half a turn of the yoke will alter the clearance
by 1 /50
inch (0-5
mm)).
