1.
Turn on Controller Console by pressing the On/VR
key. Green light above On/VR key will illuminate
when power is on. Pressing the On/VR key twice will
put the unit in VR mode. VR will appear on the
screen along with the Rate that is being sent from
the computer. Press On/VR key again to toggle back
to manual mode. (Mode and rate changes take effect
with the release of the key.)
2. To change rates manually whether in manual or in
VR mode, simply touch the Up/Down arrow keys.
This will change the Controller to the rate you select
manually. To return to VR, simply touch the On/VR
key to toggle back to VR mode.
3. Engage the hydraulic flow by pushing FORWARD on
the tractor remote hydraulic lever. The remote lever
must be LOCKED OPEN in this position to provide
constant flow to the drive motor.
John Deere tractors with Sound-Gard® body: Use
lever lock clip to lock lever forward. See your tractor
dealer for lock purchase and installation.
John Deere 7000 Series tractors: Rotate valve
detent selector to motor position to lock lever in for-
ward position.
John Deere 8000 Series tractors: Set timer to con-
tinuous. Push lever forward until detent clicks.
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.
4. 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.
