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 hydraulic down
pressure on openers if necessary. See “ Active Hydraulic Systems ” on page 34 and “ Opener
Frame Down-Force ” on page 53.
Check for trash or mud build-up on Seed-Lok wheels. Lock up if necessary. See “ Seed-Lok™
Seed Firmer Lock-Up ” on page 61.
Check if hydraulic down pressure on openers is too high, causing gauge wheels to loose contact
with ground. Decrease hydraulic down pressure if necessary. See “ Active Hydraulic Systems ”
on page 34.
Opener disks not turning
freely
Check for trash or mud build-up on disk scrapers. Readjust scrapers if necessary. See “ Disk
Scraper Adjustments ” on page 60.
Check if scrapers are adjusted too tight, restricting disk movement. Readjust scrapers if
necessary. See “ Disk Scraper Adjustments ” on page 60.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, reduce hydraulic down pressure. See “
Active
Hydraulic Systems ” on page 34.
Check press-wheel adjustment for seeding depth. See “ Active Hydraulic Systems ” on
page 34.
Actual seeding rate
is different than desired
Check tire pressure. See “ Tire Inflation Chart ” on page 95.
Check wing gauge wheels. Proper size is 9.5Lx15 8-ply Rib Implement.
Check for build-up of seed treatment. Regularly clean off build-up.
Check seed-rate setting. See “
Setting Main Box Seed Rate ” on page 49 or “ Small Seeds
Rate ” on page 50.
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 accurately
Check tire pressure. See “ Tire Inflation Chart ” on page 95.
Check gauge-wheel tires. Proper size is 9.5Lx15 8-ply Rib Implement.
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
See “ Opener Depth (Press Wheel Height) ” on page 61.
Check that drill tongue matches tractor-drawbar height. See “ Hitching ” on page 16.
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. See “ Opener Depth (Press Wheel Height) ” on page 61.
Increase hydraulic down pressure. See “ Active Hydraulic Systems ” on page 34.
