On these models, the PTO system drives two motors,
plumbed in parallel.
Adjustment Steps:
Refer to Figure 17
1.
Have the DICKEY-john
®
Planter/Drill Control User
Level 2&3 manual at hand. Making changes to the
GROUND SPEED SETUP configuration requires
the Level 2 password.
2. Have the Operator and Seed Rate manuals at hand,
so that meter setting and fan rpm targets are known
for the seed to be planted.
3. Turn the IntelliAg
®
monitor system on.
Turn the Master switch off.
On the console, navigate to the
GROUND SPEED SETUP screen.
Record the ground speed constant:
4. Set:
5. Hitch the tractor to be used, and install the PTO
pump. Raise the planter.
6. Turn the lock disc counter-clockwise to release
the knob . Turn the knob fully clockwise to shut off
flow to the motors.
7. Start the tractor, and seed monitor. Bring the PTO
up to expected field rpm (which is often not the full
1000 rpm).
8. Turn the IntelliAg
®
Master switch on to engage the
hydraulic seed meter drive.
9. With one person observing the Magnehelic
®
pressure gauge
a
, turn the knob
counter-clockwise to obtain the pressure
recommended for this planter configuration, crop,
population and intended field speed.
Secure the knob at this setting with the lock disc.
10. Shut down the PTO. Set Master switch off.

GROUND SPEED SETUP screen.
Restore the original settings:
12. If the planter has hydraulic drive, engage it for a
“FIVE REV TEST” or similar operation to create a
hydraulic motor load. Adjust PTO oil flow for target
fan speed plus 50 rpm.
Monitor meter pressurization when planting. If it is
different than during flow setup, perform the setup steps
again, and adjust the flow control valve for the
recommended pressure.
