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. See “Row Unit
Down Pressure” on page 43.
Check for trash or mud build-up on Seed-Lok wheels.
Opener disks not turning freely
Check disk bearings.
Check spreader-scraper for mud build-up and that disks are not binding
against it. See “Disk Spreader-Scraper” on page 55.
Check opener frame for damage.
If opener disks turn freely by hand but not in field, reduce down pressure
on disk opener. See “Row Unit Down Pressure” on page 43.
Check press wheel adjustment. See “Press Wheel Adjustments” on
page 48.
Actual metering rate is different
than desired
Check tire pressure. Proper inflation is listed on the “Tire Inflation Chart”
on page 68.
Check tire size. See “Specifications and Capacities” on page 66.
Regularly clean seed treatment from seed cups.
Check drill box setting.
See “Material Rate Adjustments” on page 30.
Acremeter does not measure
accurately
Check tire pressure. Proper inflation is listed on the “Tire Inflation Chart”
on page 68.
Check tire size. Proper size is 9.5L x 15 for 15 foot drills and 11L x 15 for
20 foot and 24 foot drills.
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 acremeter is correct for width of drill. Refer to the parts man-
ual.
Press wheels not compacting the
soil as desired
Check press wheel adjustment. See “Press Wheel Adjustments” on
page 48.
Increase down pressure on disk openers. See “Row Unit Down Pres-
sure” on page 43.
