We’ve got a disc blade for every application and soil type. Smooth-edged for loose dirt to deeply notched for heavy soil and thick residue; and everything in between. Our discs are also available in a range of concavities for different tilling characteristics. High-grade, hardened boron steel gives McKay blades the strength to persevere through extreme workloads, holding an effective edge through long miles in the field, and delivering consistent results.
