Seed Flap Replacement
Refer to Figure 105
1. To replace a seed flap use a needle nose or
similar tool and squeeze the tabs together.
Pull plastic seed flap down out of metal brack-
et.
2. Push new seed flap up through metal bracket

Marker Maintenance
Refer to Figure 106
The marker arm is attached to marker body with a
3/8-inch, grade 2, shear bolt. If this shear bolt
breaks, replace it with a grade 2 bolt.
NOTE: Failure to replace the shear bolt with a
grade 2 bolt can cause marker damage.
If grease-seal cap for marker-disk-hub bearings is
damaged or missing, disassemble and clean hub.
Repack with grease and install a new seal or
grease cap.
Storage
Store the drill where children do not play. If possi-
ble, store the drill inside for longer life.
1. Unload seed box:
• Place tarp under drill or a bucket under each
seed meter.
• Use a large bucket to empty box as much as
possible. Make sure sliding seed tubes are in
the open position. Open seed meter clean out

meter.
2. Thoroughly clean seed and seed-treatment
residue from boxes and seed meters.
3. Remove any dirt and debris that can hold
moisture and cause corrosion.

repairs and service during the off season.
