Troubleshooting
Problem Solution
Uneven seed spacing or uneven stand Check for plugging in seed cup.
Check if seed tubes are plugged.
Reduce ground speed.
Check that opener disks turn freely.
Use faster drive type and move seed-rate handle to a lower setting.
Increase down pressure on openers to penetrate low spots. Refer to Opener
Down Pressure, “Adjustments,” page 13.
Check for trash or mud build-up on Seed-Lok wheels. Lock up wheels if neces-
sary. Refer to Seed-Lok, “Adjustments,” page 26.
Opener disks not turning freely Check for trash or mud build-up on disk scraper. Readjust scrapers if necessary.
Refer to Disk Scraper Adjustment, “Adjustments,” page 25.
Check if disk scrapers are too tight, restricting disk movement. Refer to Disk
Scraper Adjustment, “Adjustments,” page 25.
Check disk bearings.
Check opener frame for possible damage.
Check if opener disks turn freely by hand but not in field. If so, reduce down pres-
sure on openers. Refer to Opener Down Pressure, “Adjustments,” page 13.
Check press-wheel adjustment for seeding depth. Refer to Opener Depth,
“Adjustments,” page 13.
Actual seeding rate is different than
desired Check tire pressure. Proper inflation is listed on Tire Inflation Chart, “Appendix,”
page 35.
Check tire size. Correct size is rib implement 9.00L x 24.
Check for build-up of seed treatment on turning surfaces. Clean off build-up regu-
larly.
Check seed-rate setting. Refer to Seeding Rate, “Adjustments,” page 14.
Consider your seed weight. Seed-rate charts are calculated off seed of average
weight.
Excessive seed cracking Use faster drive type and move seed-rate handle to a lower setting.
Acremeter doesn’t measure accurately Check tire pressure. Proper inflation is listed on Tire Inflation Chart, “Appendix,”
page 35.
Check tire size. Correct size is rib implement 9.00L x 24.
Check planting operation for excessive overlap or gaps between passes.
Consider soil conditions. The drill can slip in loose soil, causing variations in acres
registered.
Check that your acremeter is for your drill. Refer to 705 and 1005 parts manual.
Uneven seeding depth Refer to Opener Depth, “Adjustments,” page 13.
Check that drill tongue matches tractor-drawbar height. Refer to Hitching Tractor to
Drill, “Preparation and Setup,” page 7.
Press wheel not compacting soil as
desired Increase down pressure on openers. Refer to Opener Down Pressure, “Adjust-
ments,” page 13.
