Troubleshooting
Problem Solution
Uneven seed spacing or uneven stand Check for plugging in seed cups.
Check for plugging in seed tubes.
Reduce ground speed.
Check if opener disks are turning freely.
Use faster drive type and position seed-rate handle to a lower setting.
Increase opener spring pressure to penetrate low spots. Refer to Down-Pressure
Springs, “Adjustments,” page 12.
Check for trash or mud build-up on Seed-Lok wheels.
Opener disks not turning freely Check for trash or mud build-up on disk scraper. Readjust scraper. Refer to Disk
Scraper Adjustment, “Adjustments,” page 19.
Check if scraper is adjusted too tight, restricting disk movement. Refer to Disk
Scraper Adjustment, “Adjustments,” page 19.
Check disk bearings.
Check opener frame for damage.
If opener disks turn freely by hand but not in field, reduce down pressure on disk
opener. Down-Pressure Springs, “Adjustments,” page 12.
Check press wheel adjustment. Refer to Press Wheels, “Adjustments,” page 12.
Actual seeding rate is different than desired Check tire pressure. Proper inflation is listed on Tire Inflation Chart, “Appendix,” page
29.
Check tire size. Proper size is 9.5L x 15".
Regularly clean seed treatment from seed cups.
Check drill box setting.
Refer to Seeding Rate, “Adjustments,” page 14, for instructions on calculating seed-
ing rate.
Excessive seed cracking Use slower drive type and position seed-rate handle to a higher setting.
Position seed-cup handles to a lower notch.
Acremeter doesn’t measure accurately Check tire pressure. Proper inflation is listed on Tire Inflation Chart, “Appendix,” page
29.
Check tire size. Proper size is 9.5L x 15".
Check planting operation for excessive overlap or gaps between passes.
Consider soil conditions. Loose soil and slippage will cause variations in acres regis-
tered.
Check that your acremeter is for your width of drill. Refer to the parts manual.
Uneven seeding depth Refer to Seeding Depth, “Adjustments,” page 12.
Press wheels not compacting the soil as desired Reset press-wheel depth. Refer to Press Wheels, “Adjustments,” page 12.
Increase down pressure on disk openers. Down-Pressure Springs, “Adjustments,”
page 12.
Grain box not emptying evenly Certain models do not have the same number of seed cups between each divider of
bulkhead. The section with more cups will empty sooner.
