Zone-Builder® Subsoiler

Alleviates compaction with minimal surface disturbance

The Unverferth Zone-Builder subsoiler alleviates compaction with minimal surface disturbance, allowing crop roots to access moisture and nutrients deeper in the soil. The lead coulter cuts through residue and opens a path for the straight-leg shank that cuts through hardpan up to 20" deep. Customize the Zone-Builder with numerous tillage attachment options to fit your operation's needs.
