  To prevent excessive seed cracking with your GREAT PLAINS Seeders, consider the following: reduce speed if your field speed is too high, use clean seed, change the seed meter wheel, verify the seed count on the seed bag with the seed meter wheel if the seed size is incorrect, clean the seed meter wheel and add more talc lubricant if there's a buildup of seed treatment, replace worn or damaged seed meter wheels, replace a worn or damaged meter slide, use clean, new seed if the seed is damaged, old, or dry, and ensure you are using the correct wheel family for the meter (green wheel for 25 Series and black wheel for 20 Series).

  A GREAT PLAINS Seeders hydraulic marker may function improperly due to leaks in hose fittings or connections (check all fittings and connections), a low tractor hydraulic oil level (check the oil level), loose or missing bolts or fasteners (check all bolts and fasteners), or a plugged needle valve (open, cycle markers slowly, and reset the valve).

Why don't the drill boxes on my GREAT PLAINS 2020P empty evenly?
- C
  Chelsea SchultzSep 5, 2025
  Uneven emptying of drill boxes on your GREAT PLAINS Seeders can occur for several reasons: the right and left-hand seed rates might not be set the same (readjust rates), tire sizes or tire inflation might not be equal on the right and left gauge wheels (correct tire size or tire inflation), one or more meters might be shut off (open the meters), the opener seed tube could be plugged (raise the drill and clean out the seed tube with wire), the sliding seed tube might be plugged (clean out the sliding seed tube), drive chains could be damaged or missing (replace drive chains), or drive torque requirements might differ on the right and left gauge wheel drives (check gauge wheels and tires).

Why is the marker disk on my GREAT PLAINS 2020P Seeders not marking properly?
- J
  Jason MooreSep 7, 2025
  The marker disk on your GREAT PLAINS Seeders might not be marking properly because the marker folding linkage does not have enough slack or there is insufficient disc angle for conditions. Maximum down float should be limited by the slot at the rod end of the marker cylinder. You can increase the disc angle, or reverse the marker disc entirely.

Why am I getting population alarms on my GREAT PLAINS 2020P Seeders?

  Michael HaleySep 12, 2025
  Population alarms on your GREAT PLAINS Seeders can be caused by false alarms or actual seed rate errors due to the monitor setup having an incorrect row count and/or spacing. Review the drill configuration and monitor setup to resolve this.

Why is my GREAT PLAINS 2020P Seeders planting too little?
- J
  jennifer93Nov 16, 2025
  If your GREAT PLAINS Seeders are planting too little, several factors could be the cause. It might be due to using the incorrect seed size for the meter wheel, causing skips, in which case you should replace the meter wheels to match the seed. Other potential causes include worn meter components (replace them), an incorrect seed rate or sprocket combination (check seed rate information), excessive field speed (slow down and check the seeding rate chart), or incorrect tire size or air pressure (correct them). Also, check the seed level in the seed box and fill it if necessary, verify the field size, add more talc lubricant, clean out the seed meter if there's a buildup of seed treatment, ensure the seed flow shut off is fully open, clean out any plugged sliding or opener seed tubes, replace...

- S
  Shirley AliNov 24, 2025
  Uneven seed spacing with your GREAT PLAINS Seeders can occur due to several reasons. You might be operating at excessive field speed, so slow down and check the Seeding Rate Chart. Using unclean seed can also cause this issue, so switch to clean seed. Ensure proper seed lubrication. Clean out the seed meter if there's a buildup of seed treatment. If Seed-Lok™ is plugging, lock it up. Replace any damaged or missing seed flaps. Check if the opener disks are not turning. Raise the drill and clean out any plugged opener seed tubes. Inspect and replace any worn or rusted sprockets or chain idlers. Check and replace any damaged or worn seed meter wheels. Replace a worn seed meter slide and clean out any plugged sliding seed tubes. Finally, verify that you are using the correct seed meter wheel f...
