The EGO High-Performance Blade Set for 22" Super Composite Mowers optimizes the powerful torque and fast blade speeds of the 22-inch Super Composite deck mowers to deliver superior mulching performance that turns grass into fine fragments and leaves a sharp, clean cut. The Upper Blade is the second lawn mower blade of the Select Cut™ multi-blade system and is also included in this set. The lower High-Performance Blade is interchangeable with a High-Lift Bagging Blade (available separately) to customize your cut. The High-Performance Blade is designed for exclusive use with POWER+ 22'' Super Composite Mower with Select Cut™ System and Touch Drive Self-Propelled Mowers (LM2236SP, LM2240SP). Genuine EGO parts are designed specifically for your POWER+ tools to ensure compatibility, quality, and performance (nuts and bolts not included).
