Subsoiler Krtek

 

Technology

1 Deep loosening zone without mixing. Loosening depth 19.75"─23.5". Shanks are in one row. The hooked shanks 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 subsurface layer up to the depth of 23.5".

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. Enables loosening of subsurface 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  waterlogged lands.

High performance

  • High working speed up to 8 mph.
  • Optimum shape of shanks for safe penetration into the soil without mixing it with biologically inactive soil.
  • Superior stability of the machine with possibility of accuracy depth guiding with the use of gauge wheels.
