8TEN LawnRAZOR Blade for Snapper C21409R C21509R C21559BV CP21409R CP21509R Walk Behind 7026407AYP (Mulching)

What It Is

This is a mulching blade (OEM replacement part 7026407AYP) designed for Snapper walk-behind mowers with 21-inch decks. It lifts and recuts clippings into fine particles for nutrient return, ideal for users who want to skip bagging.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Fits only 21-inch Snapper decks. Measure your deck width—a 20- or 22-inch deck won’t work.
• Model compatibility: Verified for Snapper models C21409R, C21509R, C21559BV, CP21409R, and CP21509R. Check your model number under the seat or on the frame.
• OEM vs aftermarket: This is a direct OEM replacement (part #7026407AYP). No modifications needed if your mower originally used that part number. For non-Snapper brands, measure center hole diameter (typically 1-inch) and blade length (21 inches) to verify fit.

Key Things to Know

• Mulching quality: The 8TEN LawnRAZOR design uses a serrated edge and raised wing to create vacuum lift. Works best with dry grass—wet clippings may clump.
• Installation difficulty: Easy. Single bolt (usually 5/8-inch or 15/16-inch socket). Torque to 40-50 ft-lbs. Use thread locker if your mower vibrates heavily.
• Sharpness out of box: Most users report it’s sharp enough to start, but a quick touch-up with a file improves cut quality on thick grass.
• Common gotcha: This blade is heavier than standard Snapper blades (about 1.5 lbs). Check your mower’s spindle bearing condition—worn bearings may vibrate or fail sooner under the extra weight.

Should You Buy It

Buy this if you have a compatible Snapper 21-inch walk-behind and want a durable, OEM-fit mulching blade that recycles clippings effectively. It’s a strong value at $29.95, with high user ratings confirming reliable performance. Skip it if you prefer bagging or have a different brand/deck size—generic blades may be cheaper but risk poor fit or reduced lift.
