Primary Tillage

6│DT Subsoil Ripper
Eliminate yield-robbing, root-zone compaction, increase soil porosity and utilize deeper soil moisture and nutrients
The Orthman 6|DT subsoil ripper is designed as a soil conservation tool that destroys deep compaction layers to increase moisture intake, reduce runoff and increase yields. With a working depth ranging from 8-20 inches, the 6|DT enables your field to soak up moisture and produce to the best of its ability. The 6|DT provides maximum tillage without the loss of moisture from evaporation and is the most effective tool available to correct yield-robbing and moisture-denying compaction layers.
