The Ultra-Disk from Great Plains is a hybrid between a European high-speed disc and a standard disc harrow. With 24 inch blades mounted to individual, heavy-duty C-shanks and more clearance between gangs, the Ultra-Disk is designed to endure heavy-residue field conditions. Parallel gangs enable soil to be worked from 2-5 inches deep for consistent, primary tillage at higher operating speeds than a conventional disc.

Serrated, low-concavity SpeedBlades cut and incorporate residue better than traditional concave blades. These SpeedBlades are self-sharpening and turn 5% faster than concave blades to power through heavy residue and thoroughly mix soil at high speeds without ridging. Farmers can customize their Ultra-Disk with one of three finishing attachments to fit their field conditions. Each hydraulically-controlled rear attachment creates a uniform seedbed by breaking up clods and consolidating soil for uniform density.
