Model 657 DCR - Combination Disc Chisel
From Primary Tillage
The Award-Winning Wil-Rich 657 DCR (Disc, Chisel) is the outstanding performer for today's farmer. The 657 was named by Farm Industry News' readers as one of the best, most innovative products of 2006 and was one of the recipients of the 2006 FinOvation award. The 657 DCR is available with a hydraulic depth control cutting gang. The 20 inch diameter cutting blades can be your choice of smooth blades, for slicing residue, allowing more residue to remain on top soil. Or concave blades, slicing and mixing residue with soil for blacker top soil. For mixing and breaking the soil, you have the options of chisel plow shanks or a combination of chisel plow shanks followed by deep till shank.
