Case-IH Magnum tractors: Lock lever forward in
detent position. You may need to turn up detent pres-
sure to its maximum setting. Do not tie hydraulic
lever past detent position with a strap. See your trac-
tor dealer for details.
Other tractors: Lock lever forward in detent position.
You may need to turn detent pressure to maximum
or use a mechanical detent holder to hold lever for-
ward. See your tractor dealer for proper means of
providing constant flow.

Press Engage key to activate drive. Green light
above Engage key will illuminate.
Note: If you do not move within 10 seconds, the auto-
matic disengagement feature will disengage the
drive. To begin planting again, you must press the
Engage key.
5.
The Console display shows two numbers while oper-
ating: “Set” rate is the rate you tell the system to
plant, and the “Out” rate is the calculated rate based
on the actual rotations of the drive. The “Out” read-
ing is monitoring the drive system; it isn’t monitoring
population. It verifies that the drive system is func-
tioning properly.
Note: The “Out” readings will normally fluctuate within
5% of the “Set” rates. This fluctuation is evidence
of the drive system compensating for minor fluctu-
ations in ground speed.
6.
If “Out” rate varies from the “Set” rate by more than
20%, an audible alarm will sound.
7.
If Controller is powered directly from the battery or
via unswitched power port, make sure to power Con-
sole off when tractor is shut down, in order to prevent
tractor battery drain.
When calibrating, make sure that you choose a calibra-
tion speed that is representative of your average planting
speed.
