Clutch Lock-Up
In the event of a mechanical or electrical failure of the
clutch of its controlling circuit, the clutch may be
mechanically locked in the engaged mode, using three
bolts stored near the hand crank.
This permits completion of a planting session when
repair or replacement is not an immediate option.
Note: When locked up, meters will continue supplying
seed even with the drill raised. For short moves
without seeding, set variable rate gearboxes to 0.
For longer moves, remove lock-up bolts or remove
chains.
Refer to Figure 80 and Figure 81
1. Remove the three M8-1.25 ×14mm 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 14 mm 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.
