d.
Check power to system < 12 volt power will
cause drive to behave erratically - often
problem manifests itself in speed loop.
Drive Shuts off while planting:
a.
If it occurs after 20 seconds of not planting,
such as turning on headlands, operation is
normal safety shutoff (on units with radar speed
signal).
b.
Check setting of speed signal interrupter switch
- reposition as necessary to keep actuator from
disengaging while planting.
c.
1.5 second delay shutting off drive - causes:
chain binding, inadequate hydraulics.
Drive will not achieve desired rate:
a.
Recheck calibration number and rerun
calibration procedure if necessary.
b.
Check to make sure that your desired rate is
within the range of the meter that is installed.
c.
Inadequate hydraulic flow. Adjust flow control to
higher position. Check with flow meter if flow is
suspect.
d.
Field speed too high. Check maximum planting
rate in seed chart for rate that you are planting.
e.
Check sprocket combinations; see Assembly
and Parts Manuals for the planter you are
operating (30P and 40P models).
f.
Check speed shown on cab console against
other speedometer - tractor, planter monitor. If
drive speed is significantly higher, recalibrate
speed on drive.
Drive plants significantly higher than desired rate:
a.
Recheck calibration number and rerun
calibration procedure if necessary.
b.
Ensure that you have installed the correct seed
meter.
c.
Check sprocket combinations; see Assembly
and Parts Manuals for the planter you are
operating (30P and 40P models).
d.
Check speed shown on cab console against
other speedometer - tractor, planter monitor. If
drive speed is significantly higher, recalibrate
speed on drive.
Drive continues to rotate after tractor has stopped:
a.
Contamination or wear in Proportional Valve (P/
N#19798). Remove and inspect. Blow out with
compressed air. Check o-rings and reinstall.
Replace if necessary.
Fluid weeping from motor shaft seal:
a.
Excessive back pressure in return hose. Check
quick coupler connection. Use motor control
port for return if available.
