the following elements of a 3P4025AH planter:
• Seeds at each row unit seed tube:
Medium and larger seeds are individually counted with
high accuracy. Small seed sensing may be limited to
seed stoppage (“blockage”) detection.
• Ground speed:
The standard magnetic pickup
a
at the ground drive
allows the monitor to calculate and report population.
Once setup for the planter and your display preferences,
and configured for the current crop rates/limits, the
monitor is typically used in the “OPERATE” mode. Refer
to the DICKEY-john

PM400 Operator’s Manual for
monitor operation details.
Both the DICKEY-john
®
manual and this manual contain

You may experience more nuisance alarms with radar.
