    What to do if press wheel or openers plugging on GREAT PLAINS 1205NT?
    • A
      Andrea FosterAug 20, 2025
      If the press wheels or openers on your GREAT PLAINS Farm Equipment are plugging, it might be due to planting conditions being too wet. Waiting for drier weather may resolve this. Alternatively, there might be too much down pressure on the openers, which can be resolved by reducing the down pressure. Other causes may include backing up with the drill in the ground (clean out and check for damage), failed disk bearings (replace them), or a worn or damaged scraper (replace it).

    How to fix press wheels not compacting soil as desired on GREAT PLAINS Farm Equipment?
    • J
      James TorresAug 22, 2025
      If the press wheels on your GREAT PLAINS Farm Equipment are not compacting the soil as desired, it could be due to several factors. The soil might be too wet or cloddy, in which case you should wait until drier weather or rework the ground. The hitch height could be incorrect, so readjust it. Also, the press wheel depth might not match the coulter depth, requiring a readjustment of the press wheel depth. Finally, there might not be enough down pressure on the disk openers, so increasing the down pressure could solve the problem.

    Why is raising and lowered drill rough or uneven on GREAT PLAINS 1205NT Farm Equipment?
    • B
      Billy CarterAug 26, 2025
      If the raising and lowering of your GREAT PLAINS Farm Equipment drill is rough or uneven, it could be due to several reasons. The wheel arm pivot casting might need lubricating, so lubricate them. Check the hydraulic fittings for leaks. Also, the rephasing cylinders might not be bled properly.

    What to do if coulters and drill going too deep with GREAT PLAINS 1205NT?
    • R
      Renee HarmonAug 27, 2025
      If your coulters and drill are going too deep with your GREAT PLAINS Farm Equipment, it might be because there is too much weight applied. Also, the depth control setting could be incorrect, so reset the depth control. Another possible cause is an incorrect press wheel adjustment; set the press wheels to a shallower depth.

    Why is the marker functioning improperly on GREAT PLAINS Farm Equipment?
    • B
      bmorrisonAug 30, 2025
      If the marker on your GREAT PLAINS Farm Equipment is functioning improperly, check all hose fittings and connections for oil leaks. Ensure that the tractor hydraulic oil level is adequate by adding hydraulic oil if it's low. Inspect for any missing or loose bolts or fasteners, and tighten them as needed. If the needle valve is plugged, open it, cycle the markers slowly, and then reset the needle valve.

    What causes feed cup sprockets to lock up on GREAT PLAINS 1205NT Farm Equipment?
    • X
      xjohnsonSep 2, 2025
      If the feed cup sprockets on your GREAT PLAINS Farm Equipment are locked up or the feed cup drive shaft is twisted, it could be due to foreign matter lodged in one or more feed cup sprockets. Clean out the feed cup sprockets and use clean seed. Another cause might be dried liquid insecticide inside the feed cups. Remove the buildup by disassembling each feed cup and scraping the foreign substance from the turn surfaces.

    Why marker disk does not mark on GREAT PLAINS Farm Equipment?
    • A
      Anthony FordSep 4, 2025
      If the marker disk on your GREAT PLAINS Farm Equipment does not mark, it may be because the marker folding linkage does not have enough slack to allow the marker disk to drop into field depressions. Ensure maximum down float is limited by the slot at the rod end of the marker cylinder, and make sure the marker cylinder is fully extended. Another solution is to reverse the marker disk to pull or throw dirt.
