Electric Clutch Lock-Up
In case of electric clutch failure, an electric clutch can be
mechanically engaged.
Refer to Figure 35 and Figure 36
1.
Remove the three M8-1.25x14mm metric bolts
from their storage locations near the clutch. Save the
nuts.
2. At the clutch, align the cutouts with the holes .
3. Insert the M8-1.25 ×14mm metric bolts .
If you observe half the hole obstructed by a metal disc
, you are not at a cutout.
If the entire hole is obstructed by a metal disc , you are
not at a cutout.
When at a cutout, the bolt will screw in with minimal
resistance until the bolt head reaches the clutch face.
Note: Use only the provided 14mm length bolts. Longer
bolts will damage the clutch. Shorter bolts may not
effect a lock-up. Replacement bolts are Great
Plains part number 802-782C.
Shaft Monitor Operation (Option)
The optional shaft monitor generates an alarm if any one
or more of the three meter shafts on the drill stop turning
for more than 30 seconds.
Refer to Figure 37
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 30 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 30 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.
