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 a faster drive type and close seed-cup doors to narrower position.
Check if openers have enough down pressure to penetrate soil. Increase hydrau-
lic down pressure on openers if necessary. Refer to Opener Down Pressure,
“Adjustments,” page 33.
Check for trash or mud build-up on Seed-Lok wheels. Lock up if necessary. Refer
to Seed-Lok Lock Up, “Adjustments,” page 36.
Check if hydraulic down pressure on openers is too high, causing gauge wheels
to loose contact with ground. Decrease hydraulic down pressure if necessary.
Refer to Opener Down Pressure, “Adjustments,” page 33.
Opener disks not turning freely Check for trash or mud build-up on disk scrapers. Readjust scrapers if necessary.
Refer to Disk Scraper Adjustment, “Adjustments,” page 36.
Check if scrapers are adjusted too tight, restricting disk movement. Readjust
scrapers if necessary. Refer to Disk Scraper Adjustment, “Adjustments,” page 36.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, reduce hydraulic down pres-
sure. Refer to Opener Down Pressure, “Adjustments,” page 33.
Check press-wheel adjustment for seeding depth. Refer to Opener Depth,
“Adjustments,” page 35.
Actual seeding rate
is different than desired Check tire pressure. Refer to Tire Inflation Chart, “Appendix,” page 60.
Check wing gauge wheels. Proper size is 9.5L-15 6-ply.
Check for build-up of seed treatment. Regularly clean off build-up.
Check seed-rate setting. Refer to Seed Rate Calibration, “Adjustments,” page 23.
Consider your seed weight. Seed-rate charts are based on average seed weights.
Excessive seed cracking Use slower drive type and open seed-cup doors to a wider position.
Acremeter doesn’t measure accu-
rately Check tire pressure. Proper inflation is listed on Tire Inflation Chart, “Appendix,”
page 60.
Check gauge-wheel tires. Proper size is 9.5L-15, 6-ply.
Check planting 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. Refer to the 2S-2600 parts manual.
Uneven seeding depth Refer to Opener Depth, “Adjustments,” page 35.
Check that drill tongue matches tractor-drawbar height. Refer to Tractor Hookup,
“Drill Preparation and Setup,” page 9.
Chain-debris/retainer clip Be sure retainer clip is facing opposite way of chain travel.
Press wheel not
compacting the soil as desired Reset press-wheel depth. Refer to Opener Depth, “Adjustments,” page 35.
Increase hydraulic down pressure. Refer to Opener Down Pressure, “Adjust-
ments,” page 33.
