Electric Clutch Lockup
Refer to Figure 31
In case of electric clutch failure, electric clutches can be
bolted together.
1. Align cutouts at bolt holes .
2. Insert M8-1.25x14mm long metric bolts .
Note: Use only 14mm length bolts as provided or ma-
chine damage will occur. Longer bolts will damage
the clutch. Shorter bolts may not effect a lock-up.
3. Unbolt field coil housing and make sure it is
allowed to move freely.
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.
IMPORTANT !
When lubricating the planter, do not allow lubricant to
enter the clutch, or clutch slippage will result.
Row-Unit Operation
IMPORTANT !
IMPORTANT! Do not back up with row-units in the
ground, because this will cause severe damage and
row-unit plugging.
For information on row-unit adjustments, see “25 Series
Row-Unit Adjustments” on page 47. For more informa-
tion on troubleshooting row-unit problems, see “Trouble-
shooting” on page 65.
