1 | Deep loosening zone without mixing. Loosening depth 50–60 cm. Loosening chisels 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.
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 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-strength refined materials in connection with eXtra STEEL line technology guarantee long service life of our machines even in the most difficult conditions.
Due to minimum of adjusting points the operation and subsequent maintenance are very easy steps that anybody can perform.
