3Pk 16515 Mulching Blades Compatible with Snapper 48" 1759055YP, 1757303

What It Is

This is a 3-pack of 16.5-inch mulching blades designed for Snapper 48-inch zero-turn mowers. They replace OEM part numbers 1759055YP and 1757303, and are intended for cutting grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify three things: deck size must be exactly 48 inches (these blades are not for 46" or 52" decks). OEM part numbers should match 1759055YP or 1757303—check your current blade or owner’s manual. Center hole is a 5-point star pattern (common on Snapper ZTRs); measure your blade’s center hole diameter (approx. 1.125") and overall length (16.5"). These are aftermarket replacements, not OEM Snapper, but are listed as direct fit for Snapper models like the 1759055YP and 1757303. If your mower uses a different blade pattern (e.g., round center hole with keyway), these will not work.

Key Things to Know

• Quality: Aftermarket blades are often made of hardened steel but may be slightly thinner than OEM. Check thickness (typically 0.187" to 0.25") to ensure durability.
• Installation difficulty: Easy—just lift deck, remove old blade bolt, swap blades, and torque bolt to 70–90 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Gotcha: Mulching blades have a more curved design than standard lift blades. They work best with a mulching kit (plug or baffle) installed on the deck. Without it, clippings may clump.
• Sharpness: Blades come unsharpened or with a dull edge. You may need to sharpen them before first use for best performance.

Should You Buy It

If you own a Snapper 48" ZTR with OEM blades 1759055YP or 1757303 and want a cost-effective 3-pack for mulching, this is a solid choice—especially given the 5-star rating (though only 1 review). It’s ideal for homeowners who mulch regularly and want to keep a spare set on hand. Skip it if you need OEM exact thickness or have a different deck size.
