4.2 Tractor Hook up

Connect the ½” hydraulic line to activate the opener lift/lower. The opener lift/
lower line is marked with a wide red band. The opener lock-up ball valves must
be open in order to lower the shanks. Both

the opener line and lock-up ball

valves are lo

cated at the hydraulic manifold.

It is very important that the hydraulic fluid dum

p (yellow band)

lines return

UNRESTRICTED back to the tractor hydraulic reservoir. There are male and
female pioneer quick couplers with the flow restrictors removed supplied with
the Seed Hawk. Be sure to use these sets of couplers for the case drains.

Any alterations or restrictions in this line will cause damage to the
implement that will NOT be covered by warranty.

Always connect the case drain line (yellow band) to return hydraulic fluid back
to the tractor reservoir. The case drain line is a ¾” (19 mm) line from the
hydraulic manifold. The case drain line(s) MUST return to the tractor UNRE-
STRICTED. Failure to do so can cause damage to the hydraulic cylinders or fan
motor and will void Manufacturer’s Warranty. The case drain(s) must be con-
nected even when lowering the wings. Seed Hawk

recommends that the case

drain(s) have their own port into the tractor’s reservoir.

Connect the other pair of ½” hydraulic lines to activate the wing up and down

(green bands)

, and the standby supply to the shank and wing cylinders. The

manifold supply line is marked with a narrow green band, and the return line
is marked with a wide green band. This tractor lever is locked in full pressure
position while seeding.

NOTE: Do not tee the man-

NOTE: Some newer tractors

cannot return to the hydrau-

lic reservoir. Refer to specific

tractor Operator's Manual

and/or consult your dealer

for tractor requirements

NOTE: DO NOT plug the

case drain line during storage;

damage to the gauges and

manifold may occur.
