GICOOL 21 Inch High Lift Blade Fit for 56V Lawn Mower, Compatible with LM2100SP LM2101 LM2102SP LM2142SP LM2114, Replaces OEM AB2101

What It Is

This is a 21-inch high-lift blade designed to improve mulching and bagging performance on select 56V cordless lawn mowers. It’s intended for users who want better grass clipping lift and finer cut quality than standard OEM blades.

Fitment & Compatibility

Before buying, confirm your mower deck size is exactly 21 inches. This blade is compatible with models LM2100SP, LM2101, LM2102SP, LM2142SP, and LM2114. It replaces OEM part AB2101. Measure your existing blade’s center hole diameter (typically 1-inch) and ensure the drive pin slots align—most 56V models use a standard 5-point star pattern. Check that your mower’s spindle bolt matches the blade’s center hole size; torque specs vary by model. Aftermarket blades like this may have slightly different balance or thickness than OEM, so verify clearance with your deck housing before installation.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and a block of wood to lock the blade. No special tools needed.
• High-lift design: Increases airflow for better bagging and mulching but may draw more power and reduce runtime slightly on battery mowers.
• Check balance: After installing, spin the blade by hand to ensure it doesn’t wobble. Unbalanced blades can cause vibration and damage the spindle.
• Sharpening: These blades are hardened steel—resharpenable with a file or grinder, but don’t overheat the edge. Replace when bent or excessively worn.

Should You Buy It

Buy this if you own one of the listed 56V mowers and want sharper, more aggressive cutting for thick grass or heavy leaf mulching. It’s a solid upgrade over worn OEM blades at a fair price, especially if you value better bagging performance. Skip it if you prefer standard lift or have a different deck size.
