Subsoiler Krtek

 

Technology

1 Subsoiling zone without mixing. Subsoiling depth 50–60 cm. Subsoilingtines are in one row. The hooked tines cut through the soil and do not form clods.
2 Re-compaction zone. Optimum soil re-compaction ensures good water infiltration and soil water capillarity to the surface.

Subsoiler Krtek is designed for deep loosening of soil without mixing it with subsoil layer up to the depth of 60 cm.

Higher yields due to significantly better microclimate in soil

The subsoiler is designed for work in all soil conditions which is enabled by hydraulic automatic protection. It does not have to be used every year, when using anti compaction methods, soil is left uncompacted due to the action of water, frost, roots, and micro-organisms. It enables loosening of subsoil layer without risk of mixing of inactive soil with topsoil. For use when it is not possible to prevent excessive compaction of the soil (e.g. after sugar beet). To restore drainage in wetlands.

High performance

  • High working speed up to 12 km/h.
  • Optimum shape of tines for safe penetration into the soil without mixing it with biologically inactive soil.
  • Very good stability of the machine with possibility of precise depth guiding with the use of depth wheels.
