Irregular or incorrect seed spacing. Consider your planting speed. Slow down if necessary. For correct speed, refer to
Planting Rate Charts, “Adjustments,” beginning on page 15.
Check tire pressure. Refer to Tire Inflation Chart, “Appendix,” page 30.
Drive wheels slipping. Reduce down pressure on row unit. Refer to Row Unit
Adjustments, “Adjustments,” page 11.
Check that correct sprockets are installed on transmission shafts. Refer to Plant-
ing Rate Charts, “Adjustments,” beginning on page 15.
Seed spacing not as indicated in charts. Check that tires are inflated to proper pressure. Refer to Tire Inflation Chart,
“Appendix,” page 30.
Examine seed for inconsistent size. Do field check and adjust sprockets accord-
ingly.
Check that correct sprockets are installed on the transmission shafts. Refer to
Planting Rate Charts, “Adjustments,” beginning on page 15.
Excessive speed may be causing row-unit bounce. Reduce ground speed when
planting.
Charts are approximate. Slight variations due to wear may produce seed-spacing
variations.
Scattering of seeds. Reduce planting speed.
Check seed tube for proper installation.
Examine seed tube for wear or damage. Replace seed tube if necessary.
Seed tubes and/or openers plugging. Do not allow planter to roll backward when lowering. Lower planter only when tractor is
moving forward.
On four-wheel-drive tractors, avoid turning tractor when planter is down and stationary.
Inconsistent seed depth. Increase down pressure on row unit. Refer to Row Unit Adjustments, “Adjustments,”
page 11.
Inspect seed tube for plugging or improper installation. Check that seed tubes are hooked
properly in shank of row unit.
None of the row units are planting. Pin between counter-shaft and seed transmission sheared. Repair cause of pin shearing
and replace pin.
Closing wheels leave severe imprint in
soil. Reduce down pressure on closing wheels. Refer to Row Unit Adjustments, “Adjust-
ments,” page 11.
Closing wheels not firming soil around
seed. Increase down pressure on closing wheels. Refer to Row Unit Adjustments, “Adjust-
ments,” page 11.
Closing wheel running on top of seed fur-
row. Realign closing wheels. Refer to Row Unit Adjustments, “Adjustments,” page 11.
Repeated shearing of shaft cotter pin. Drill shaft not aligned properly. Loosen bearing and align shaft.
Drive-wheel chain consistently falls off. Chain may be too long. Remove offset link.
If chain links are stiff, oil or replace chain.
Check if trash is dislodging chain; if so, install trash guards.
No seed being planted. Check that seed hopper is full of seed.
Opener disks and side gauge wheels
plugging. Adjust gap between opener disks and side gauge wheels. Refer to Side Gauge
Wheels, “Adjustments,” page 12.
