657 DISK CHISEL
The Wil-Rich 657 Disk Chisel is ideally suited for the first tillage pass in high residue conditions. Coulter disks on the 657 are offset from shanks to allow shank assemblies to properly till and bury crop residue. The split-the-middle design offsets the coulter disks 7.5 inches (19 cm) from the shanks to dislodge root balls and more efficiently start the decomposition process. The combination of coulter disks in the front for sizing crop residue and careful shank placement around wheels minimizes plugging.
