What It Is

This is a 3-pack of aftermarket mulching blades designed for 61-inch zero-turn mower decks, primarily replacing OEM Scag, Ferris, and Husqvarna parts. They are intended for heavy mulching on commercial or large residential mowers, cutting clippings fine enough to leave on the lawn.

Fitment & Compatibility

• Deck size: Only for 61-inch cutting decks. Measure your deck width to confirm.
• Model compatibility: Fits Scag IS1500ZX, IS2000Z, IS2500Z with 61" deck. Also fits Ferris and Husqvarna models that use OEM part numbers listed (Scag 48111, 481708, 481712, 482787; Ferris 1520842; Husqvarna 539101733).
• OEM vs aftermarket: These are direct replacements for the listed OEM numbers. Check your current blade’s part number to confirm match.
• Measurements: Blade length is approximately 20.5 inches, center hole diameter 1 inch, with a 5-point star center. Verify these dimensions against your existing blade before installation.

Key Things to Know

• Quality: Aftermarket blades may not be as precisely balanced as OEM. Check balance before installing to avoid vibration.
• Installation difficulty: Moderate. You’ll need a socket wrench and possibly a blade removal tool. Torque to 70-80 ft-lbs per manufacturer specs.
• Mulching performance: These blades have a higher lift and more cutting edge area than standard blades, which can strain the engine if you mow too fast. Keep ground speed moderate.
• Common gotcha: Some users report needing to re-sharpen after the first few hours if mowing sandy or rocky terrain. Aftermarket steel may be softer than OEM.

Should You Buy It

Buy this set if you have a 61-inch Scag, Ferris, or Husqvarna zero-turn and want an affordable mulching blade replacement that matches OEM specs. It’s a solid value for budget-conscious owners who don’t mind checking blade balance and can handle basic installation. Not ideal if you need premium, long-life blades for commercial daily use—OEM may last longer.
