This airflow helps stand grass upright before cutting and moves clippings toward the discharge chute or grass-collection system.\u003c\/p\u003e\n\u003cp\u003eHigh-lift blades are commonly selected for strong side-discharge performance, bagging grass clippings, cutting taller or thicker grass and producing a clean, even cut.\u003c\/p\u003e\n\u003cp\u003eBecause high-lift blades move more air, they can create more dust in dry conditions and generally require more engine power than low-lift blades.\u003c\/p\u003e\n\u003ch2\u003eInstallation and Safety\u003c\/h2\u003e\n\u003cp\u003eShut off the mower, remove the key, disconnect the spark-plug lead or battery when appropriate, and allow all moving components to stop before servicing the mower deck. Install the blade with the cutting edges and lift wings facing in the direction specified by the equipment manufacturer.\u003c\/p\u003e\n\u003cp\u003eUse the manufacturer's blade-bolt torque specification. Inspect the blade bolt, washer, spindle, adapter and mounting surface before installation. Replace damaged or excessively worn components.\u003c\/p\u003e\n\u003cp\u003eFor consistent cutting and deck balance, consider replacing all blades on a multi-blade deck as a matched set.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat mower does the Rotary 11224 blade fit?\u003c\/h3\u003e\n\u003cp\u003eThe Rotary 11224 fits select Exmark 60-inch mower decks that require a 20-1\/2-inch high-lift blade with a 15\/16-inch center hole.
