Build quality, testing, and practical use

• The cutting edges are painted to resist rust during installation and break-in; expect the paint to wear off with use, which is normal.
• A rigorous test regimen (Rockwell hardness, V-bend, blade chip, balance, performance, and field testing) supports confident performance evaluation.
• Balanced design and sturdy construction aim to reduce vibration and deliver steady mowing across a range of grass densities.

Tips for real-world mowing

In everyday use, ensure proper installation with a secure, balanced mounting. Keep blades sharp and inspect for wear or bending before each season. While these blades are designed for reliable mulching, results can vary with grass type and maintenance practices. Consider replacing blades in pairs to maintain balanced cutting performance over time.
