Model 2220-DCD (Disc-Chisel-Disc)

The Model 2220-DCD (Disc-Chisel-Disc) is the answer to the farmer who wants the benefit of the Disc-Rip-Disc but does not want to deep-till. The 2220-DCD has 32” Spring clamp shank assemblies set on 15” centers which allows you to mix and cover more residue than you can with deep-till shanks set on 30” centers. Maximum depth of the shank is 12 to 14” depending on disc gang depth. Shanks can be fitted with different ground engaging tools, standard is the 2” chisel spike also available are 3” and 4” twisted shovels for additional mixing of residue and 16’ and 18” sweeps.
Disc gang angle is as simple as pulling a pin and setting the angle at 10, 15 or 20 degrees while the disc gang depth is hydraulically controlled from the tractor cab. Disc scrapers are standard on front and rear gangs.
