We manufacture Grey Iron(GG 20,25) and Ductile Iron(500/7) Roller rings for agricultural machineries. Packer rings, Furrow rings, Crosskill rings, Cambridge rings and Pulverizer rings are the oldest and most versatile tillage tools used on the agriculture field today. The Crescent Roller rings can be used throughout the entire tillage process. Pulling a Roller ring will insure better seed soil contact and improve seed germination.
