How do these high-lift blades improve cutting and collection?

High-lift blades create stronger upward airflow inside the deck, lifting grass blades for a cleaner cut and moving clippings efficiently toward the discharge or bagging system. The result is more uniform mulching, faster bag fill, and reduced re-cutting of clippings.

• High-lift profile increases suction for cleaner cuts
• Sharper edges reduce tearing and fraying of grass
• Improved airflow helps faster collection and even spread
• Three-blade pack keeps an extra blade on hand for rotation or spares

How should I install and maintain these blades for best life?

Installation follows standard mower blade replacement steps: disconnect spark, support deck, remove blade bolt, and fit blade so the cutting edge faces the rotation direction. Regular inspection and sharpening extend life and maintain cutting performance.

• Always follow manufacturer torque specs and safety procedures
• Balance blades after sharpening to avoid vibration damage

• Keep one spare blade from the 3-pack for faster service in the field
