Adjusting the ridging discs

The height of the ridging discs from the soil can be adjusted in pairs, and the distance and horizontal tilt relative to the plant row can be adjusted individually. The different settings must be coordinated with each other.

For the adjustment, the following applies:

  • The deeper a horizontally tilted ridging disc cuts vertically into the arable soil, the more soil will be heaped onto the plant row.

  • When the horizontal distance is greater and also the horizontal tilt is steeper relative to the plant row, a ridging disc heaps up more soil. When the horizontal distance is smaller and also the horizontal tilt is flatter relative to the plant row, a ridging disc heaps up less soil.

  • The higher the forward speed during hoeing operation, the more soil is heaped by the ridging discs onto the plant rows. If the amount of soil that is heaped should remain the same when the forward speed is increased, the height of the ridging discs must be increased and the distance and horizontal tilt of the ridging discs relative to the plant rows must be reduced.

  • If the hoeing depth is changed, see section Adjusting the hoeing depth and the amount of heaped soil should remain the same, the height of the ridging discs from the arable soil must also be changed.

  1. To adjust the height of ridging discs that are installed on a parallelogram via a star parallelogram:

    Follow steps 2 to 6.
  2. Lower the implement on the field with the three-point power lift.
  1. Loosen the bolt 2 for the guide tube 3 in the star parallelogram.
  2. Push the ridging discs 4 with the section tube 1 up or down in the guide tube until the ridging discs are in the right position.
  3. Tighten the bolt for the guide tube.
  4. Adjust the height for all of the ridging discs in the same way.

  5. To adjust the height of ridging discs that are installed on a parallelogram via a rigid mount:

    Follow steps 8 to 12.
  6. Lower the implement on the field with the three-point power lift.
  1. Loosen the bolt 2 for the guide tube 3 in the share bracket.
  2. Push the ridging discs 4 with the section tube 1 up or down in the guide tube until the ridging discs are in the right position.
  3. Tighten the bolt for the guide tube.
  4. Adjust the height for all of the ridging discs in the same way.

  5. To adjust the lateral distance of a ridging disc:

    Follow steps 14 to 18.
  6. Lower the implement on the field with the three-point power lift.
  1. Loosen the bolt 2 for the guide tube 3.
  2. Push the ridging disc 4 with the sliding tube 1 in the guide tube inwards or outwards until the ridging disc is in the right position.
  3. Tighten the bolt for the guide tube.
  4. Adjust the lateral distance for all of the ridging discs in the same way.

  5. To adjust the horizontal tilt of a ridging disc relative to the plant row:

    Follow steps 20 to 26.
  6. Lower the implement on the field with the three-point power lift.
  1. Loosen the nut 2 on the bolt 3.
  2. Unscrew the nut and lower the ridging disc 1 until the cylinder dowel pins 4 no longer engage in the locking plate 5.
  1. Turn the ridging disc 1 with the locking plate 2 to the left or right around the longitudinal axis of the bolt 4 until the ridging disc has the right tilt angle.
  2. Press the ridging disc up with the locking plate so that the cylinder dowel pins 5 slide into the locking holes 6.
  3. Tighten the nut 3 on the bolt.
  4. Adjust the horizontal tilt for all of the ridging discs in the same way.
