Adjusting the star closers

The star closers are used on plowed 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 out the implement.
  2. Secure tractor and implement.

The star closers must not move the seed in the soil. Adjust the working depth to maximum 0,39 in (1cm) on the bottom of the furrow. If the star closers push up soil, reduce the working depth or increase the throughput through the star closers.

  1. Unlock the adjustment lever 1.

  2. To increase the working depth:

    Move the adjustment lever towards +

or

To reduce the working depth:

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

or

Bring the star closers in the tracks into the desired position.

  1. To park the implement:

    Bring the star closers on all rows into the top position.
  2. Lock the adjustment lever in the grid.

  3. To check the adjustment:

    Drive for 98,43 ft (30m) at working speed and then check the work pattern.
NOTE
To adjust star closers centered to the furrow, adjustment bushes are present in different distances.
  1. Dismount nut and locking washers 2.

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

    Bring the adjustment bushings 3 and 4 into the desired position.

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

    Increase the distance between the 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 adjustment:

    Drive for 98,43 ft (30m) at working speed and then check the work pattern.
