From choice, the Cirrus can be equipped with a Crushboard in front or behind the disc segment. If it is undulations that require levelling or hard clods that have to be broken, the Crushboard is in the right position in front of the discs. Under very light conditions the Crushboard, positioned behind the discs, can, in addition, help settle the earth flow. The reconsolidation will be even more uniform. For the Cirrus with Crushboard, the front tyre packer can also be specified.
