Engineered for Precision. Built for Performance.
Designed as a direct OEM-fit replacement for Degelman Pro-Till® and Kinze Mach Till™ high-speed tillage systems, this 20-inch notched blade delivers the durability, precision, and reliability that professional operators demand. Manufactured from premium boron steel and heat-treated for exceptional fracture toughness, it withstands the extreme forces of high-speed residue management and abrasive field conditions.
Key Features
- Exact OEM Fitment – 20" diameter, 6.5 mm thick blade with a dedicated 4-bolt, 5.25" bolt circle. Ensures a tight seal to protect hub bearings from dust and moisture—unlike universal 8-hole designs that expose seals to contamination.
- High-Performance Material – Constructed from boron steel with a 50-54 rockwell hardness, precision heat-treated for superior impact resistance and long wear life under demanding tillage conditions.
- Optimized Cutting Profile – Aggressive notched edge provides outstanding residue penetration and chopping performance, ideal for heavy corn stalks and compacted soils.
- Cross-Compatible Design – Fits Degelman Pro-Till® 20, 26, 33, 40 and Kinze Mach Till™ 201, 261, 331, 401 models—one blade that covers both leading systems.
- Ready to Ship – In-stock inventory and flat-rate shipping minimize downtime for emergency or planned maintenance needs.
