Hipa LM2100 LM2100SP High Lift Mower Blade Set for EGO 21 Inch Lawn Mower Blade Replace AB2101 CH3706059001 Pack of 1

What It Is

This is a high-lift mower blade set designed for EGO’s 21-inch cordless lawn mowers. The raised wing profile increases airflow under the deck, improving grass lift for a cleaner cut and better bagging performance in thick or tall grass.

Fitment & Compatibility

• Deck size: 21 inches (measure your blade length—must be exactly 21 inches center-to-center).
• Models: Fits EGO LM2100, LM2100SP, and likely LM2101, LM2102SP, LM2113SP, LM2142SP, and LM2156SP. Confirm your model number on the underside of the deck or owner’s manual.
• OEM replacement: Direct swap for EGO part numbers AB2101 and CH3706059001. Aftermarket, but matches OEM dimensions.
• Measure before buying: Check blade length (21”), center hole diameter (usually 1”), and offset/angle. High-lift blades are thicker than standard—ensure your deck has clearance and your battery can handle the extra load.
• Not for: Any non-EGO 21” mower or older EGO models with different blade mount patterns (e.g., LM2000 series).

Key Things to Know

• Installation: Easy—one bolt per blade (usually 15mm or 5/8” socket). Torque to 35-45 ft-lbs. Use a blade stopper or wedge to prevent spinning.
• Battery impact: Higher lift creates more drag, reducing runtime by 10-20% compared to standard blades. Expect more frequent charging.
• Noise & vibration: May be slightly louder and cause more vibration than OEM flat blades. Check blade balance before installing—unbalanced blades can damage the spindle.
• Not for mulching: These are designed for bagging. If you mulch leaves or grass, stick with a low-lift or mulching blade.

Should You Buy It

Buy this if you primarily bag clippings and want better pickup in damp or tall grass, and you’re okay with a small hit to battery life. Skip it if you mulch or need longer runtime—stick with EGO’s standard low-lift blade (AB2101). At $18.99, it’s a fair value for improved bagging performance, but check fitment carefully.
