Population,
Single Row
Shutter opening too wide - interfering with
meter pressurization
Adjust shutter to lower setting.
Shutter opening too narrow - starving meter
of seed (low seed pool)
Adjust shutter to higher setting.
Y-tube partially or completely closed,
reducing bulk flow to meter or causing
bridging
Open Y-tube for row
Meter starvation due to bridging at shutter
Re-adjust for shutter bridging (page 77).
If seed is treated, increase seed lubricant.
Meter starvation due to bridging above inlet,
caused by low seed delivery air flow
Clear bridge (page 77). Check that seed delivery system is
getting sufficient fan air, and that there are no other obstructions
upstream.
Meter starvation due to bridging above inlet,
caused by high levels of seed treatment
Clear bridge (page 77). Increase seed lubricant.
Skips due to low meter pressurization at one
or several rows
Check shutter setting.
Check for excess wear on seed drop brush.
Check for loose or leaking pressure hose.
Skips due to skipping chain
Check for worn chain, worn idlers, and low chain slack
Skips due to debris in disk pockets
Remove rain covers. Inspect and clean out disks.
Row has blank disk installed
Replace with seeding disk.
Seed sensor obscured
Clean out seed tube (see page 100).
Seed tube plugged
Raise planter, expose bottom of seed tube and clean out.
Swath Command clutch slipping/failed
Swath Command solenoid malfunction
Check for slippage with tubing to clutch disconnected.
Check tubing to valve, and lead to WSMB harness.
