Ketofa AB2000 20-Inch Lawn Mower Blade for EGO Power+ 56V LM2022SP, LM2020SP and LM2021 Lawn Mower Models, Replaces for 3705369001, 3705369000

What It Is

The Ketofa AB2000 is a 20-inch replacement blade designed for EGO Power+ 56V cordless mowers, specifically the LM2022SP, LM2020SP, and LM2021 models. It’s a direct aftermarket alternative to OEM blades 3705369001 and 3705369000, intended for mulching, bagging, or side-discharge cutting on residential lawns.

Fitment & Compatibility

Before buying, confirm your mower deck size is exactly 20 inches—this blade will not fit smaller or larger decks. It only fits the three listed EGO models (LM2022SP, LM2020SP, LM2021). Measure your existing blade length (hole center to hole center) and ensure the center hole diameter matches your spindle (typically 1 inch for these EGO models). Check that the blade’s shape and offset match your OEM blade—EGO uses a specific lift profile for efficient mulching. Aftermarket blades may have slight dimensional differences, so compare thickness and balance hole positions if your mower has a blade brake.

Key Things to Know

• Quality & Durability: Made from heat-treated steel with a coated edge; reviews note it cuts well initially but may dull faster than OEM on thick or damp grass. Inspect after a few uses for bending.
• Installation Difficulty: Easy swap—requires a 15/16-inch or 24mm socket and a torque wrench (recommended 40-50 ft-lbs). Use thread locker on the bolt to prevent loosening.
• Common Gotchas: The blade may require rebalancing out of the box—check with a blade balancer before installing. It’s slightly lighter than OEM, which can affect cutting performance on very tall grass. Ensure the blade orientation (lift edge up) matches your mower’s rotation (clockwise from above).
• Fitment Nuance: Some users report the center hole is slightly tight on the spindle; file it gently if needed. Not compatible with EGO models not listed (e.g., LM2100 series).

Should You Buy It

Buy the Ketofa AB2000 if you need a budget-friendly replacement for your EGO 20-inch mower and are comfortable checking balance and fitment yourself. It’s a good choice for light to moderate residential use, but skip it if you want OEM-level longevity or have a high-use commercial lawn—stick with genuine EGO blades for consistent performance.
