Adjusting the throughput of the disc gangs

The disc gangs can be set to high throughput A or low throughput B:

  • If the disc gangs are set to high throughput, the tines can work at a depth of 14,5cm with the disc gangs fully lifted, without the discs penetrating the soil. If the tines work at a depth of 30cm, the discs are working at a depth of 15cm.

  • If the disc gangs are set to low throughput, the tines can work at a depth of 22,5cm with the disc gangs fully lifted, without the discs penetrating the soil. If the tines work at a depth of 30cm, the discs are working at a depth of 7,5 cm.

High throughput is pre-set at the factory, and must be selected under the following conditions:

  • High amount of organic matter

  • High amounts of crop residues

  • If the discs are used at the maximum working depth

Low throughput must be selected under the following conditions:

  • If the pulling force requirement should be reduced at the maximum working depth

  • Under wet conditions and high working depth of the tine array

  • When the tines should work deep, but not with the discs

  1. To change the disc gangs from high throughput to low throughput:

    Lower the running gear into transport position.
  2. Set the working depth of the disc gangs to the smallest value using the green 3 tractor control unit.
  3. Secure each disc gang with suitable lifting gear and slings against lowering.
  4. Unscrew the nuts 1 on all of the bearing plates 3 of the disc gangs and remove them along with the wedge lock washers 2.
  1. Pull the bolts 5 along with the wedge lock washers out of the bearing plates 1 and disc gang carriers 4.
  2. Remove the diagonal braces 2 along with the wedges 3.
  1. Turn the disc gangs 5 around the longitudinal axis until the previously free holes 2 of the bearings plates 1 are aligned with the holes of the disc gang carriers 3.
  2. Insert the bolts 4 along with the wedge lock washers through the holes on all of the bearing plates and disc gang carriers.
  3. Put on the diagonal braces along with the wedges.
  4. Put the nuts along with the wedge lock washers onto all of the bolts.
  5. Tighten all of the nuts.

  6. To change the disc gangs from low throughput to high throughput:

    Perform all of the work steps in the same way. At step 7, however, turn the disc gangs in the other direction around the longitudinal axis.
