Each blade is designed for high-lift airflow to improve grass lift and bagging performance, and comes factory-painted on the edges to reduce surface rust and protect installers during handling. The set replaces part numbers 04265400 and 1134-9210-01, so it’s a simple swap for many standard 42\" mower spindles.\u003c\/p\u003e\n\n\u003ch3\u003eWhich mowers will these blades fit?\u003c\/h3\u003e\n\u003cp\u003eThese blades are made for 42\" decks used on specific Gravely and Ariens zero-turn and Zoom models.

The notches reduce weight and can help prevent clogging in heavier turf, while the high-lift shape boosts suction for even clippings distribution.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-lift profile enhances grass stand-up for a uniform cut.\u003c\/li\u003e\n  \u003cli\u003eNotches reduce drag and minimize clogging in dense lawns.\u003c\/li\u003e\n  \u003cli\u003eBetter suction improves bagging and side-discharge efficiency.\u003c\/li\u003e\n  \u003cli\u003ePainted edges reduce rust and protect installers prior to break-in.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the exact specifications and how do I install them?\u003c\/h3\u003e\n\u003cp\u003eEach blade measures roughly 14 4\/5\" long, 2 1\/4\" wide and 0.197\" thick with a 5\/8\" center bore. The set includes three identical blades—enough for a typical 42\" three-blade deck. Installation follows standard blade replacement steps: secure the mower, remove old blades, align the center hole and bolt, torque to manufacturer specs, and check clearance before use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eLength: 14.8\" | Width: 2.25\" | Thickness: 0.197\".\u003c\/li\u003e\n  \u003cli\u003eCenter hole diameter: 5\/8\" to match common spindle shafts.\u003c\/li\u003e\n  \u003cli\u003ePackage contains three blades for a full 42\" deck replacement.\u003c\/li\u003e\n  \u003cli\u003eAlways use correct bolt torque and safety procedures during install.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs there anything special I should know about the paint on the cutting edge?\u003c\/h3\u003e\n\u003cp\u003eThe cutting edges are coated with protective paint to help prevent surface rust and to soften handling risk during installation. That coating is intentional and will wear away quickly once the blades start cutting; do not scrape it off before first use. This finish protects the blade during storage and transport and reduces the chance of accidental scratches during handling.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePainted cutting edges guard against corrosion during storage.\u003c\/li\u003e\n  \u003cli\u003eThe paint also reduces sharpness-related handling injuries before install.\u003c\/li\u003e\n  \u003cli\u003eExpect the coating to wear off naturally after initial mowing passes.\u003c\/li\u003e\n  \u003cli\u003eDo not forcefully remove the paint; it’s part of the product design.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This ILONPA 3-pack is intended for owners and technicians of Gravely and Ariens 42\" zero-turn or Zoom decks who need a direct-fit, cost-effective blade replacement.
