Troubleshooting
Actual seeding rate
is different than desired
Check tire pressure. Proper inflation is listed on Tire Inflation Chart,
“Appendix,” page 80.
Check tire size. Proper size is
395/55B 16.5 12 ply
.
Check for build-up of seed treatment in seed cup. Disassemble cups and
scrape off any build-up.
Check seed-rate setting. Seeding rates will vary with seed weight and size.
Refer to Setting the Seeding Rate, “Adjustments,” page 30.
Excessive seed cracking
Use a faster drive type and a lower seed-rate-handle setting.
Position seed-cup handles to a lower notch.
Monitor does not measure accurately
Check tire pressure. Proper inflation is listed on Tire Inflation Chart,
“Appendix,” page 80.
Check tire size. Proper size is
395/55B 16.5 12 ply
.
Check seeding operation for excessive overlap or gaps between passes.
Consider soil conditions–loose soil and slippage will cause variations in
acres registered.
Recalilbrate monitor.
Uneven seeding depth
Check that openers have sufficient down pressure. Refer to Opener Down
Pressure, “Adjustments,” page 27.
Press wheel not
compacting soil as desired
Reset press-wheel depth. Refer to Opener Depth, “Adjustments,” page 27.
Increase down pressure on openers. Refer to Opener Down Pressure,
“Adjustments,” page 27.
Press wheels or openers plugging
Consider field conditions. Drilling in damp or wet conditions may increase
this problem.
Reduce down pressure on openers. Refer to Opener Down Pressure,
“Adjustments,” page 27.
Do not back up or stop and allow drill to roll back with openers in ground.
Check optional Seed-Lok wheels.
Seed-cup sprockets locked
up or twisted seed-cup shaft
Check for foreign material lodged in seed-cup sprocket.
Look for dried liquid insecticide in seed cups. Remove build-up by disas-
sembling each cup and scraping turning surfaces.
Chain-Debris/retainer clip
Be sure retainer clip open end is facing the opposite way of chain travel.
