Oregon 91-604 Gator G3 21-7/16" Mulching Mower Blade for John Deere S220 S240 X350

Product Description

The Oregon Gator® G3™ 91-604 Lawn Mower Blade is designed for excellent cutting performance in a variety of conditions, including wet, dry, and sandy turf. Gator G3 blades provide superior mulching, fewer bag stops, and cleaner side discharge compared with standard manufacturer blades. It’s not just a replacement blade—it’s an upgrade.

The aggressive blade angle increases airflow to move clippings up and out of the mower deck, while the Gator Mulcher® design processes clippings more efficiently and can reduce the need for bagging. The Oregon 91-604 fits select John Deere S-Series, X-Series, and Z-Series mowers and replaces multiple John Deere OEM blade numbers.
