NOTE: When using a Seed
Hawk toolbar only, shank
pressure will be read on a
3000 psi gauge mounted
directly on the block.
4.6.1 Opener Shank Operation
Standard Toolbars
1. Ensure that there is power going to the Seed Hawk switch control box, and
that the ball valves on the back of opener hydraulic manifold are open.
2. Engage the tractor hydraulics lever that the RED band hose (opener circuit)
is connected to.
4. Moving in a forward direction, turn
on the
PWM DOWN PRESSURE
switch, then turn on the SHANK/
LIQUID PUMP switch on. This will
engage the opener shanks.

3. Lock the tractor hydraulics lever
that the GREEN banded hoses (wing
circuit) are connected to. The full
tractor pressure is shown on the top
right (4000 psi gauge) of the hydraulic
manifold block.
Refer to Section 4.4 pertaining to the control system being used.
5. Turing the min-max DOWN PRESSURE dial allows the user to increase or
decrease the desired packing pressure to achieve proper packing and penetra-
tion forces to seed.
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.
6. Turn off the SHANK/LIQUID PUMP switch to disengage the opener
shanks.
