482878 Mulching Mower Blades Kit Compatible with 36" & 52" Deck A-riens Gravely John Dee-re Bob-cat Ex-Mark Bunton Lawn Mowers，3 Pack

What It Is

This is a 3-pack of aftermarket mulching blades (part #482878) designed to replace OEM blades on zero-turn mowers with 36-inch or 52-inch cutting decks. Mulching blades feature a curved, high-lift design to recut clippings into fine particles for lawn fertilization.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This kit fits 36" and 52" decks only. Measure your deck width—if it’s 42", 48", 54", or 60", these won’t work.
• Blade dimensions: Each blade measures roughly 18.5" long, 2.5" wide, with a 5/8" center hole and a 3/8" offset. Measure your existing blade length, width, and hole size.
• Brands listed: Compatible with A-riens, Gravely, John Dee-re, Bob-cat, Ex-Mark, and Bunton mowers. Check your model number against the seller’s list—some newer models may have different blade patterns (e.g., oval holes, different offsets).

Important: These are not OEM parts. They may vary slightly in thickness, balance, or edge profile. Always test one blade for fit before installing all three.

Key Things to Know

• Quality concerns: At $34.99 for a 3-pack, these are budget blades. Expect thinner steel (around 0.19") compared to OEM (0.25"). They may dull faster or warp under heavy use.
• Installation difficulty: Easy—requires a socket wrench and blade removal tool. Torque bolts to 70–90 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: Mulching blades require a mulching plug or baffle kit to work effectively. If your deck lacks these, you’ll just get poor discharge and clumping.
• Balance check: Aftermarket blades often need balancing. Buy a blade balancer (~$10) to avoid vibration that can damage your spindle.

Should You Buy It

If you need a quick, cheap mulching blade replacement for a 36" or 52" deck and don’t mow heavy grass or rough terrain, this kit works. But if you mow professionally, want longer blade life, or need exact OEM fit, spend more on a branded set (Oregon, Gator, or A-riens OEM). For light residential use at this price, it’s a decent stopgap.
