3. Press the Selector Knob again to save the setting. When seeding, this
screen will show the system pressure setting and a triangular marker will move
up and down the bar graph to show the measured system pressure as com-
pared to the set pressure.
4. Press the ACK (Activate Clutch Key) on the monitor to disengage the
opener shanks.
In order to get the proper packing and penetrating forces per field, we recom-
mend lowering the opener shank pressure from the tractor at the beginning
of each field. Every new Seed Hawk toolbar manufactured has a factory preset
with the opener shank pressure set at approximately 1000 psi.
When the proper amount of packing pressure is applied to the shank, the chain
that connects the seed and fertilizer knives will be pulled taught. Once the chain
is tight, take note of the packing pressure gauge reading. In optimal conditions,
an additional 200 psi of packing pressure is recommended. In wet conditions re-
duce the pressure accordingly to avoid over-compaction of soil, especially with
canola and other small seeds. Maximum Packing Pressure is 1500 psi.
IMPORTANT! Always ensure that the opener shank is maintaining seed and
fertilizer separation. Seed Hawk
® Recommends checking the actual seed and
fertilizer separation in each field. Soils and moisture conditions vary. Over time
the opener bolts, if not tightened on a yearly basis, will not function as intended,
causing seed and fertilizer separation to change.
