Troubleshooting
Problem Solution
Uneven seed spacing or stand Check for plugging in seed cups.
Check for plugging in seed tubes.
Reduce ground speed.
Check that opener disks turn freely.
Shift speed-change gearbox to a faster drive-type and adjust the seed-rate
handle to a lower number.
Increase spring pressure so openers penetrate low spots. Refer to Opener
Down-Pressure Adjustments, “Adjustments,” page 22.
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. Re-adjust scraper if neces-
sary. Refer to Disk Scraper Adjustment, “Adjustment,” page 34.
Check if disk scraper is restricting disk movement. Refer to Disk Scraper
Adjustment, “Adjustment,” page 34.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, reduce down pressure on
opener. Refer to Opener Down-Pressure Adjustment, “Adjustments,” page
22.
Check if press wheels are adjusted too high. Refer to Press Wheel Adjust-
ment, “Adjustments,” page 22.
Actual seeding rate is different than
desired Check tire pressure. Proper inflation is listed on Tire Inflation Chart,
“Appendix,” page 50.
Check gauge-wheel size. Proper size is 11L x 15 8-ply.
Clean seed-treatment build up out of seed cups and shafts.
Refer to Setting the Seeding Rate, “Adjustments,” page 23, for instructions
on calculating seeding rate.
Excessive seed cracking Use slower drive type on gearbox and adjust seed-rate handle to a higher
number.
Position seed-cup doors to a lower notch. Refer to Set Seed-Cup Doors,
“Adjustment,” page 23.
Acremeter doesn’t measure accurately Check tire pressure. Proper inflation is listed on Tire Inflation Chart,
“Appendix,” page 50.
Check gauge-wheel tire size. Proper size is 11L x 15 8-ply.
Check seeding operation for excessive overlap or gaps between passes.
Consider soil conditions; loose soil and slippage will cause variations in
acres registered.
Check that your acremeter is for your drill width. Refer to the parts manual.
Uneven seeding depth Check if drill tongue is running level with ground. Refer to Hitch Height
Adjustment, “Drill Preparation and Setup,” page 10.
Check if drill frame is level. Refer to Leveling Adjustment, page 34.
