Product Description
Sold as a set of 3 aftermarket replacement blades for commercial mower applications using blade family Rotary 3404 / Oregon 91-622 / GDU10231 / 0450300. Each blade measures 18″ in length and 2-1/2″ in width, with a 5/8″ round center hole. External search results show this family used across multiple deck configurations, commonly: 2 blades for 36″ decks 3 blades for 50″, 52″, and 54″ decks Because the family spans multiple deck sizes, the safest approach is to present this listing as a multi-deck family product rather than forcing one single deck size.
