Genuine John Deere knives have a tungsten carbide coating for high-quality chopping performance, longer wear life, and lower engine power demands. Knives stay sharp longer, reducing sharpening intervals and fuel consumption.
Inferior coatings, such as those used by many imitators, result in low-quality cutting performance, shorter wear life, and increased engine power demands. Knives dull quickly, increasing sharpening intervals significantly. The cutaways show the superior hard-facing qualities of Genuine John Deere knives.
