THE NEW Wil-Rich 657-DCR is a one-pass tillage tool that acts as a disk, chisel and ripper, all in one. Wil-Rich says the new tillage tool turns and mixes residue with topsoil while reducing soil compaction. It works well in various soil and crop conditions. The gangs are hydraulically controlled for setting depth and can be raised completely out of the ground. The tillage tool allows the choice of individually mounted concave blades or straight coulter blades mounted on gangs.
