Flow Adjust: Hydraulic Drive IntelliAg
®
Singulator Plus™ & Finger Pick-Up Planters
On hydraulic drive models YP1225#56, YP1625#56,
YP2425, YP2425F, YP3010HDP, YP3020P, YP3025,
YP4010HDP, YP4020P, YP4025, YP4025F and
3PYP#56, the PTO system drives two
a
or three motors,
plumbed in parallel:
a.
One fan motor (two on model YP2425F) generates
an airflow for seed delivery and/or fertilizer delivery
(models YP2425F, YP4025F).
b.
The other motor, for seed meter operation, is under
seed monitor control, via a proportional flow solenoid
valve.
When engaged at typical field seed rates, the seed drive
motor reduces flow to the delivery fan. The seed motor
needs to be engaged at least briefly during setup to
choose a flow rate that keeps the delivery fan at optimal
speed.
Adjustment Steps:
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 the fan rpm target is known for the seed to
be planted.
3.
Loading seed is not required. Loading fertilizer is
not recommended. If you do load seed, set out
recovery means to capture seed metered during
testing, or use section clutches
b
to disable
metering.
4.
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:
5.
Set:
6.
Hitch the tractor to be used, and install the PTO
pump. Raise the planter. Unfold the planter.
Release the lock disc
counter-clockwise to
release the knob
. Turn the knob fully clockwise to
shut off flow to the motors.
Entanglement and Crushing Hazard:
Use extreme caution in the hitch area when the PTO is
operating.
8.
Start the tractor, and seed monitor. Bring the PTO
up to expected field rpm (which is often not the full
1000 rpm).
9.
Turn the IntelliAg
®
Master switch on to engage the
hydraulic seed meter drive.
10. With one person observing the fan rpm readout on
the seed monitor, turn the knob
counter-clockwise until the fan is at the rpm
recommended for this planter configuration, crop,
population and intended field speed.
Secure the knob at this setting with the lock disc.
11. Shut down the PTO. Set Master switch off.
12. On the console, navigate to the
GROUND SPEED SETUP screen.
Restore the original settings:
Monitor fan rpm when planting. If it is lower than during
flow setup, perform the setup steps again, and set the
valve for a higher rpm.
a. If the Yield-Pro
®
PTO pump system was ordered for ground drive, the hydraulic drive is still on a dedicated circuit. In this case, load
seed, but ignore the steps to compensate for seed drive motor load.
