Shaft Monitor Operation
The optional shaft monitor generates an alarm if any one
or more of the three main seed box meter shafts on the
drill stop turning for more than 20 seconds.
To operate shaft monitor, turn system on by activating
on-off switch on monitor head. If seed-cup shafts are
turning, all three indicator lights are illuminated and no
alarm sounds.
If any seed-cup shaft stops for 20 seconds, an alarm
sounds and the indicator for that section flashes on the
monitor, designating the failed shaft.
Note: The 30-second delay is to prevent nuisance alarms
when turning at the end of the field.
Note: If a failure does occur and an alarm sounds, re-
member you have traveled for 20 seconds without
planting with that drill section. If due to wheel lift or
low tire pressure, you may have been planting at
progressively lower populations before that.
Note: Older (Vansco) monitors alarm dwell time was 30
seconds.

Planting Sequence
1. Lower drill openers at initial seeding point.
2. Pull forward and begin planting.
