Causes
Solutions

Check transport and contact tire sizes and
inflation (page 152).
Broken or removed chain(s) in drive system
Check chains against “Chain Routing” on
page 154.
Removed final rate Range gear(s); for
example, single hopper operation with
incorrect meter disabled
Re-install gear(s) per seed rate chart and
calibration for affected meter.
Variable rate gearbox set to zero, or too low
Re-set gearbox per calibration.

disconnected or failed
Run monitor self-test. Swap sensor with a
working row to verify failure. Replace sensor.
Material is flowing, but
is not detected by seed
monitor
This is normal during the first few meters/feet
of planting, as it takes some time for material
to reach rows.
Lower openers 3m/10ft before planting is to
begin. Monitor does not check for blockage
during first 5 seconds.
Lift switch mis-adjusted, failed or mis-wired.
Check, adjust or replace switch (page 117).
Seed monitor disconnected at hitch
Connect seed monitor.
Planting too little
(some rows)
Partial blockage in meter chamber, seed
hoses, towers, seed tubes
Treat as blockage. See “No material flow
(multiple rows)” on page 102 and “No
material flow (one or two rows)” on
page 102.
