703371 Mower Blade 21" Compatible with Briggs and Stratton, Snapper Walk-Behind Mowers 7800923 1696627 1696607 2691561 1696844, Replacement 21-Inch Mulching Blade with Bow-Tie Center Hole

What It Is

This is a 21-inch mulching blade designed for walk-behind mowers, primarily compatible with Briggs & Stratton and Snapper models. It uses a bow-tie center hole and is built to chop clippings finely for nutrient recycling on the lawn.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches—measure the blade length from tip to tip if unsure. This blade replaces OEM part numbers 7800923, 1696627, 1696607, 2691561, and 1696844. Check that your mower’s spindle hole matches the bow-tie shape (not a standard star or round hole). It fits Snapper walk-behinds and many Briggs & Stratton engines, but verify your model number against Snapper’s compatibility list. If your mower uses a different mounting pattern, this won’t work.

Key Things to Know

• Quality: 5.0 rating from only 2 reviews—limited real-world feedback. Likely a standard steel blade; inspect for warping or dull edges on arrival.
• Installation: Moderate difficulty. You’ll need a socket wrench and blade removal tool. Always disconnect the spark plug and tip the mower (air filter side up) before swapping.
• Gotchas: The bow-tie hole is less common than star or round—double-check your spindle. Mulching blades work best with a mulching plug/kit; without it, you’ll get poor cut quality.
• Lift: This blade’s design may produce less lift than a standard blade—fine for mulching, but not ideal for bagging or side-discharge on tall grass.

Should You Buy It

If you have a 21-inch Snapper or Briggs & Stratton walk-behind with a bow-tie spindle and you primarily mulch clippings, this is a solid, affordable replacement. For bagging or uneven terrain, consider a standard lift blade instead.
