Seed Hawk TOOLBAR 2008 - Manual (Page 32)

OPERATION
TRACTOR HOOK UP
Change the tractor’s hydraulic filter after the first day or two of Seed Hawk operation.
Some debris may have collected in the hydraulic system during manufacturing. Changing
the filter will remove this debris, and prevent it from damaging components on the seeder
and tractor.
Shank lift and lower (Two hoses with red bands)
Connect the pair of 1/2” hydraulic lines to activate the shank lift and lower. The
shank up line is marked with a wide red band, and the shank down line is marked
with a narrow red band. The shank lock-up ball valves must be open in order to
lower the shanks. One is at the hydraulic manifold and the other is at the tractor
hook up location.

It is very important that the hydraulic fluid dump lines return
unrestricted back to the tractor hydraulic reservoir. There
are male and female pioneer quick couplers with the balls
removed supplied with the Seed Hawk. Please use these sets
of couplers for your dump lines. Any alterations or
restrictions in this line will cause damage to the implement
that will NOT be covered by warranty.
NOTE: Do not Tee manifold and fan case drain dump lines
together unless this takes place right at tractor reservoir.
Do not plug this dump line for storage.
Hydraulic Manifold (Two hoses with green bands)
Connect the other pair of 1/2” hydraulic lines to activate the wing lift and lower,
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. You must also connect the dump lines (yellow bands) to return
hydraulic fluid back to the tractor. One dump line is a 1/2” line from the (optional)
fan case drain. The other dump line is a 1/2” line from the manifold. The dump
lines must return to the tractor
unrestricted. Failure to do so can cause damage
to the hydraulic cylinders or fan motor.
This tractor lever is locked in full pressure position while seeding.
