Why the Kerner quality goes into detail.

From driving force to wave power. The Crackerwalze made by Kerner knows how to work perfectly on the field. No wonder - as it is equipped with big steel packer rings, which have a diameter of ∅ 550 mm and clearing and cutting tools. The wave profile of the compactor improves the structure even in extreme soil conditions and provides a share of fine soil for the seed covering. Additionally integrated cross bars ensure a surplus of driving force.

Grubber Komet KAL


  • clean the interspaces between the rings
  • no crop residues, no blockage
  • ideal for humid, sticky soil

Compactor Wheel

  • big steel packer rings with a diameter of 550 mm for an optimal reconsolidation of the soil
  • laterally closed rings combined with integrated clearing and cutting tools
  • compactor rings with wave profile: improve the structure on extreme soil and provide additional soil for the seed covering


  • adapter for assembling on machines of other manufacturers

The Crackerwalze offers you further advantages. It also allows blockage-free working in humid soil conditions and a better drainage of rain water. The formation of smear layers is not a problem any more. Instead the Crackerwalze ensures a balanced oxygen exchange and an optimal seedbed preparation.
