SKIL SMB2000 20-Inch Lawn Mower Blade for SKIL Mowers PM4910-10/SM4910-10

What It Is

The SKIL SMB2000 is a 20-inch replacement blade designed specifically for SKIL cordless mower models PM4910-10 and SM4910-10. It’s the OEM direct-fit part for standard mulching and bagging cuts on residential lawns.

Fitment & Compatibility

Before buying, confirm your mower model number (not just “SKIL 20V”). This blade only fits SKIL PM4910-10 and SM4910-10. Check the blade’s center hole diameter (must match your spindle) and the overall length (20 inches). Measure your old blade’s thickness and offset—this is a symmetrical blade, so no special adapter is needed. It’s OEM, so aftermarket “universal” blades may require additional washers or adapters; stick with this for guaranteed fit.

Key Things to Know

• Installation difficulty: Easy—one bolt, no special tools beyond a socket wrench. Torque to 35–45 ft-lbs.
• Sharpness: Comes sharpened, but expect to re-sharpen after 10–15 hours of use on typical grass.
• Balance: Pre-balanced from factory; still check balance after sharpening to avoid vibration.
• Common gotcha: The blade is 0.125-inch thick—thicker aftermarket blades may not clear the deck. If your mower vibrates after install, re-check the bolt torque and blade orientation (cutting edge facing grass).

Should You Buy It

Buy this if you own a SKIL PM4910-10 or SM4910-10 and want a drop-in replacement with no guesswork. It’s the right choice for maintaining factory performance—skip it if you need a mulching-only or high-lift blade for different cutting conditions.
