Ketofa AB2101 High-Lift Lawn Mower Blade for EGO 56V 21-Inch Models LM2100, LM2101, LM2102-SP, LM2100-SP, LM2142-SP - 1 Pack

What It Is

The Ketofa AB2101 is a high-lift aftermarket replacement blade designed for EGO 56V 21-inch lawn mowers. High-lift blades create stronger upward airflow to lift grass for a cleaner cut, making them ideal for bagging or mulching in thicker lawns.

Fitment & Compatibility

Before buying, confirm your mower model matches this exact list: EGO LM2100, LM2101, LM2102-SP, LM2100-SP, or LM2142-SP. The blade is 21 inches long with a 5-point star center hole and 0.25-inch thickness. It is not compatible with older EGO 20-inch models (like LM2000 series) or any non-EGO 21-inch deck. Measure your existing blade’s length and center hole shape—if it’s a star pattern, this fits. Always check your mower’s owner manual for OEM part number cross-reference (original EGO blade is part #312236900).

Key Things to Know

• Quality vs OEM: Users report this blade is slightly thinner than OEM EGO blades, which may reduce durability over time. Expect 1-2 seasons of use in normal conditions.
• Installation difficulty: Easy. Requires a socket wrench or blade removal tool. Torque the blade bolt to 35-40 ft-lbs. No special adapters needed.
• Common gotchas: High-lift blades increase battery drain on electric mowers—you may lose 10-15% runtime per charge. Also, they can be louder than standard blades.
• Balance: Some units may need light balancing after install. Use a blade balancer to avoid vibration.

Should You Buy It

Buy this if you have a compatible EGO 21-inch model and want better bagging or mulching performance on a budget. It’s a decent value at $19.99, but if you prioritize long blade life or maximum runtime, consider the OEM EGO blade instead.
