Electric Clutch Lock-Up
In case of electric clutch failure, an electric clutch can be
mechanically engaged.
Refer to Figure 48 and Figure 49
1.
Remove the rubber plugs from the oil shield
disc to allow access to the lock-up holes. Plugs
simply push out away from the clutch side.
2. Align the cutouts with the holes .
3. Insert the M8-1.25x14mm long 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.
4. Re-install the plugs so they are not lost.
Note: Use only the provided 14mm length bolts. Longer
bolts will damage the clutch. Shorter bolts may not
effect a lock-up.
Y-tubes
Refer to Figure 50
Y-tube gates can be shut off, for example:
• to plant 30in corn on a 15in planter, or
• to feed only one row for single-row planting on a
twin-row machine.
In the photograph, both meter tubes are open.
You can also shut off the Y-tube gates to clean out the air
system and meters. See “Cleaning Out Air System” on
page 97.
