Engineering & Design Overview
Hero Flat Coulters deliver pinpoint slicing accuracy through surface residue with minimal soil throwing. Built with flat plate tolerances under 0.5mm runout, they ensure uniform seed furrow opening and consistent seeding depth.
Induction hardened cutting perimeter ensures long edge retention in stony and hard no-till soils without chipping or edge deformation.
Key Engineering Features
- Ultra-flat runout tolerance (<0.5mm)
- Precision ground knife-edge bevel
- High tensile resistance to side deflection
