Adjusting the star closer

The start closers are used on ploughed or mulched soils. They cover the seed furrow with fine soil. The working depth, the position of the star closers, and the spacing between the press rollers can be adjusted.

  1. Lift the implement.
  2. Secure the tractor and implement.

The star closers must not move the seed in the soil. Adjust the working depth to maximum 1cm from the bottom of the furrow. If the star closers push up soil, reduce the working depth or increase the clearance between the star closers.

  1. Unlock the setting lever 1.

  2. To increase the working depth:

    Move the setting lever towards +

or

To reduce the working depth:

Move the setting lever towards -
  1. Make the same adjustment for all star closers.

or

Put the star closers in the tracks to the desired position.

  1. To park the implement:

    Move the star closers on all rows into the topmost position.
  2. Lock the setting lever in the grid.

  3. To check the setting:

    drive for 30m at working speed and then check the work pattern.
NOTE
To adjust the star closers at the centre of the furrow, there are setting bushings at different distances.
  1. Remove the nut and locking washers 2.

  2. To align the star closers so that they are centred relative to the furrow:

    Move the setting bushings 3 and 4 into the desired position.

  3. If the star closers push up soil or organic material:

    Increase the distance between the star closers 1 and 6 in the holder 5.

or

If the star closers do not adequately cover the seed with fine soil:

Reduce the distance between the star closers.

  1. To check the setting:

    drive for 30m at working speed and then check the work pattern.
