Hydraulic Drive Field Operations
1.
Turn on Controller Console by pressing the ON/VR
button. Green light above ON/VR button illuminates
when power is on.
Pressing the ON/VR button twice puts the unit in VR
mode. VR appears on the screen along with the Rate
from the recipe or sent from your GPS. Press ON/VR
button again to toggle back to manual mode. (Mode
and rate changes take effect with the release of the
button.)
2.
To change rates manually whether in Manual or in
VR mode, simply touch the /
arrow buttons. This
changes the Controller to the rate you select
manually. To return to VR, simply touch the ON/VR
button to toggle back to VR mode.
3.
Before planting, conduct a seed rate Calibration
(page 30) and ground speed Calibration (page 44).
4.
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
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 proper means of
providing constant flow.
5.
Press ENGAGE button to activate drive. Green light
above ENGAGE button illuminates.
If you do not move within 10 seconds, the automatic
disengagement feature disengages the drive. To
begin planting again, press ENGAGE.
6.
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.
The “Out” readings normally fluctuates within 5% of
the “Set” rates. This fluctuation is evidence of the
drive system compensating for normal variations in
ground speed.
7.
If “Out” rate varies from the “Set” rate by more than
20%, an audible alarm sounds.
8.
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.
When calibrating, make sure that you choose a
calibration speed that is representative of your average
planting speed.
