General Troubleshooting
Problem Solution
Uneven Seed
Spacing or Uneven
Stand
Check for plugging in seed cup.
Check to see if seed tubes are plugged.
Reduce ground speed.
Check opener disks to see they turn freely.
Use faster drive speed and close seed cup flutes to a more narrow position.
Spring pressure on openers could be improperly adjusted causing opener to not penetrate
low spots.
Check for trash or mud build-up on Seed-Lok
®
wheel.
Opener Disks Not
Turning Freely Check for trash or mud build-up on disk scraper. Re-adjust scraper.
Check to see if scraper is adjusted too tightly and is restricting disk movement.
Check disk bearings.
Check opener frame for possible damage.
If opener disks turn freely by hand but not in field, reduce down pressure on disk opener.
Check press wheel adjustment for seeding depth.
Actual Seeding
Rate Is Different
than Desired Check tire pressure. For proper inflation see “Tire Inflation Chart” on page 68.
Check gauge wheel size. Proper size is 9.5L x 15.
Seed treatment will affect seeding rate if the chemicals build up in seed cup. Unless cleaned
regularly, this build up can cause breakage of the seed-cup shaft.
Check speed change box setting.
For instructions on calculating seed rate see “Seeding Adjustments” on page 34.
Excessive Seed
Cracking Use slower drive speed and open flutes in seed cup to a wider position.
Position seed-cup handles to a lower notch.
Acremeter Doesn’t
Measure
Accurately Check tire pressure. For proper inflation see “Tire Inflation Chart” on page 68.
Check end gauge wheel tire size. proper size is 9.5L x 15.
Check planting operation for excessive overlap or gaps between passes.
Loose soil conditions and slippage will cause variations in acres registered.
To check accuracy of acremeter, see “Acremeter Operation” on page 29.
Check to be sure your acremeter is for your width of drill.
Uneven Seeding
Depth See “Planting Depth Adjustments” on page 33.
See “Hitching Tractor to Drill” on page 13 and “Leveling Drill” on page 20.
Press Wheels Not
Compacting Soil
As Desired Refer to “Planting Depth Adjustments” on page 33.
Re-adjust press wheel depth to match coulter depth.
Increase down pressure on disk openers.
Grain Box Not
Emptying Evenly Certain models do not have the same number of seed cups between each divider of
bulkhead. The section with the larger number of cups will empty sooner.
Seed cups close to the ends of box tend to empty sooner due to amount of seed available.
Check adjustment levers on each box to see that they are set on the same indicator number.
