Adjusting the V press rollers

The V press rollers close the seed furrow. The roller pressure, the pitch, and the distance between the press rollers can be adjusted.

Press rollers

1

350x50 serrated, for heavy soils

2

350x50 profiled, for light to medium soils. Suitable for reducing the risk of erosion

3

350x50 smooth, for light to medium soils

4

350x33 smooth, for medium to heavy soils

NOTE
To ensure that the seed is not pulled out of the soil 1, the working depth of the serrated press rollers must be shallower than the set seed placement depth.
  1. Lift the machine.
  2. Secure the tractor and machine.
  3. Unlock the setting lever 1.

  4. To increase the roller pressure:

    Move the setting lever towards E

or

To reduce the roller pressure:

Move the setting lever towards A.
  1. Lock the setting lever in the grid.

  2. To check the setting:

    Drive for 30m at working speed. Check the work pattern.

  3. If the seed furrow is not closed at the set roller pressure:

    Adjust the pitch.

  1. On light soils:

    Move the setting lever towards A

or

On heavy soils:

Move the setting lever towards E.

  1. To check the setting:

    Drive for 30m at working speed. Check the work pattern.

  2. If the seed furrow is not closed at the set pitch:

    Adjust the press roller distance.
  1. Loosen the inner lock nut and remove it.
  2. Remove the bolt 1 with the press roller.

Move the press roller 3 with the setting bushing 2 to the desired position.

NOTE
To adjust the pressure point of the press rollers at the centre of the furrow, there are setting bushings at different distances.

  1. On light soils:

    Increase the press roller distance +

or

On heavy soils:

Reduce the press roller distance -.

  1. Install the press roller with bolts.
  2. Move the opposite press roller 4 to the desired position.

  3. To check the setting:

    Drive for 30m at working speed. Check the work pattern.

  4. If the seed furrow is not closed at the set press roller distance:

    Adjust the press roller offset.
  1. Loosen the inner lock nut and remove it.
  2. Remove the bolt 1 with the press roller.
NOTE
For machines with disc closers, install the press rollers in the rear position.

  1. For higher throughput:

    Increase the distance of the press rollers 2 in the direction of travel.
  2. Install the press roller.
  3. Move the opposite press roller 3 to the desired position.

  4. To check the setting:

    Drive for 30m at working speed. Check the work pattern.
