6 Pack Pro Pack  Saves you money 

The Rotary 3404 6 Pro Pack Copperhead High-Lift Blade is a professional-grade replacement blade designed for commercial and heavy-duty residential mowers. Manufactured in the USA, it is engineered as a high-performance alternative to standard OEM blades, specifically optimized for superior bagging and grass discharge.

Key Features & Performance

• Copperhead Engineering: Part of Rotary’s premium Copperhead line, these blades are heat-treated and tempered for extended edge retention and impact resistance.

• High-Lift Design: Features an aggressive "sail" (13/16" height) that creates maximum vacuum and airflow. This ensures clean clippings, prevents clogging in wet conditions, and improves bagging efficiency.

• Commercial Durability: Built from high-quality American steel with a thickness of 0.204", designed to withstand the high-torque demands of zero-turn and walk-behind commercial mowers.
