    What to do if my Landoll VT Plus 7431 unit side drafts or moves side to side?

      Timothy MillerAug 23, 2025
      If your Landoll farm equipment is side drafting, several factors could be the cause. Ensure that the lift wheels are carrying enough weight by adjusting the depth stop and raising the implement. Check that the unit is level from front to rear and adjust accordingly. Also, level the unit side to side, ensuring the center frame and wing frames are aligned. Finally, make sure the gauge wheels are properly set to prevent the wings from going too deep.

    How to fix uneven depth with Landoll VT Plus 7431 Farm Equipment?
    • C
      Cheryl RamirezAug 25, 2025
      Uneven depth in Landoll farm equipment can stem from several issues. First, ensure the frame is level side to side. Next, check that the wing frames are level with the center frame. Verify that the lift cylinders are in phase by fully extending them and holding the hydraulic lever until all cylinders are fully extended. Adjust the depth stop and raise the implement if the lift wheels aren't carrying enough weight. Fully extend the fold cylinders to allow the wings to flex. Check tire inflation. Finally, ensure the unit is level from front to rear.

      Disc gang plugging in Landoll farm equipment can occur due to several reasons. Check if the scrapers are set too far from the disc blade; adjust them closer and evenly. The operating depth might be too deep; raise the unit. Also, excessively wet conditions can cause plugging; wait until conditions are more favorable.

      Nichole ThompsonAug 27, 2025
      If your Landoll farm equipment is leaving a center ridge, it might be due to a few reasons. The leveler may not be adjusted properly; adjust the leveler and lower the front gang. The hitch adjustment could be too low; raise the implement hitch point. Also, the gauge wheels might be carrying too much weight; raise the gauge wheels.

    • J
      Jodi MeyerSep 22, 2025
      If you have loose disc blades or shearing roll pins on your Landoll farm equipment, the gang may not be tightened properly; retighten the gang shafts to 1250-1500 ft-lbs. If gangs have run loose, they may require disassembly to remove soil to properly torque gang shafts. Replace any worn components, shafts/spools, etc.

    Why is my Landoll Farm Equipment hydraulic lift cylinder not fully extending on one side?
    • M
      Manuel KramerSep 7, 2025
      If one side of the center lift cylinders on your Landoll farm equipment is not fully extending, the center lifts may not be properly timed. Remove the 1” bolt from the adjustable radius rod on the lifts and fully retract the lift cylinders. Reinstall the radius rod bolt, adjusting it to fit the lifts in position. Check the center frame level.
