Briggs and Stratton Replacement Mower Blade 21" for Snapper Mower 7800923, 1696627, 1696607, 2691561

What It Is

This is a 21-inch replacement mower blade designed specifically for Snapper rear-engine riders and some zero-turn mowers. It cuts grass by spinning at high speed under the deck, suited for residential lawn care on standard turf.

Fitment & Compatibility

Before buying, confirm your mower has a 21-inch cutting deck—measure deck width if unsure. This blade fits Snapper models using OEM part numbers 7800923, 1696627, 1696607, and 2691561. It replaces Briggs & Stratton part 7800923. Check your current blade’s center hole diameter (typically 1-inch) and offset (usually 1-inch, but verify). Not compatible with 20-inch or 22-inch decks. Avoid using on Craftsman, Toro, or other brands without cross-referencing your exact model number.

Key Things to Know

• Quality: Aftermarket but meets OEM specs; 4.5-star rating indicates good durability for residential use. Expect resharpening 2-3 times before replacement.
• Installation: Easy with a socket wrench—lift mower, block securely, remove center bolt. Torque to 70-90 ft-lbs (check your manual). Use thread locker if bolt loosens.
• Gotcha: Some users report needing to file the center hole slightly for a snug fit on older decks. Also, ensure blade orientation—cutting edge should face upward when mounted.
• Safety: Always disconnect spark plug and wear gloves. A dull blade tears grass, so sharpen annually or after 25 hours of use.

Should You Buy It

Buy this if you own a compatible Snapper rider with a 21-inch deck and need a reliable, affordable replacement that matches OEM performance. Skip it for other brands or if you prefer genuine Snapper parts—OEM may cost more but guarantees exact fit.
