4.6.2 Loup 111 Opener Shank Operation

1. Ensure that there is power going to the Seed Hawk Loup III monitor.

2. Engage the tractor hydraulics lever that the RED band hose (opener circuit)

are connected to.

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.

4. Moving in a forward direction press

the ACK button on the monitor,

this will engage the opener shanks.

4.6.2.1 Loup 111 Shank Down Pressure Adjustment

The hydraulic down pressure applied to the opener shanks is controlled by a

closed loop system that allows the operator to enter the desired operating

down pressure. Entering the desired amount of down pressure can be done on

the monitor as well. The monitor controls a down pressure valve that main-

tains the pressure setting on the opener shanks through the control module.

A pressure sensor measures the actual hydraulic pressure and feeds it back to

the control module. The control module adjusts the down pressure valve to

maintain the system setting. As the openers move up and down with the terrain

constant force is applied to openers all equally.

1. To set and change the shank pres-

sure, press any Soft Key to bring up

the soft key menu and press “Shank”.

2. A horizontal bar graph display will

come up on the screen. Press the

Selector Knob to activate the

adjustment and then rotate the to

increase or decrease the system

pressure.

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 button on the monitor to disengage the opener

shanks.

In order to get the proper packing and penetrating forces per eld, we recom-

mend lowering the opener shank pressure from the tractor at the beginning

of each eld. 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 eld. 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.
