Engage the hydraulic flow by pushing FORWARD on the tractor remote hydraulic lever. The re-
mote 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
forward position.
• John Deere 8000 Series tractors: Set timer to continuous. Push lever forward until detent clicks.
• Case-IH Magnum tractors: Lock lever forward in detent position. You may need to turn up detent
pressure to its maximum setting. Do not tie hydraulic lever past detent position with a strap. See
your tractor 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 forward. See your tractor dealer for

The Console display shows two numbers while operating: “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” reading is monitoring the drive system; it isn’t monitoring population. It verifies that the drive
system is functioning 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 fluctuations in
ground speed.
4.
If “Out” rate varies from the “Set” rate by more than 20%, an audible alarm will sound.

If Controller is powered directly from the battery or via unswitched power port, make sure to power
Console off when tractor is shut down, in order to prevent tractor battery drain.
