When the first DK Diamond Disk was introduced in 1984, it changed the way farmers thought about tillage. Unlike traditional X-frame implements, it didn’t need feathering disks, allowing it to produce clean cuts along field edges and make turns with the disks still in the ground. Additionally, the unique diamond shape helped eliminate the ridging, skipping, gouging and rock damage that are common with other tillage tools. The DK Diamond Disk uses 26-inch concave disks for maximum soil mixing.
