5650510001 Lawn Mowers Blade Washer (2 Pack) Compatible with EGO Power + Part 20" and 21" Lawn Mowers LM2000-S, LM2020 and LM2020SP Blade Washer

What It Is

This is a genuine EGO replacement blade washer (2-pack) designed to sit between the blade and the mounting hardware on select EGO 20" and 21" lawn mowers. It provides a flat, stable surface for the blade bolt to clamp against and helps prevent blade wobble during operation.

Fitment & Compatibility

Before buying, confirm your mower model: This washer fits EGO Power+ models LM2000-S, LM2020, and LM2020SP. It does not fit older or newer EGO mowers with different spindle designs (e.g., LM2100, LM2130, or any 56V models with a different blade retention system).

Check deck size: Only for 20" and 21" decks listed above.

OEM vs aftermarket: This is a genuine EGO OEM part (part number 5650510001). Aftermarket washers may vary in thickness, outer diameter, or center hole size—stick with OEM for guaranteed fit.

Measure your existing washer: If you’ve lost or damaged the original, remove the blade bolt and measure the old washer’s outer diameter (~1.25") and center hole (~0.375"). This part matches those dimensions.

Key Things to Know

• Installation is simple: Remove the blade bolt, slide the new washer over the bolt (flat side against the blade), then torque the bolt to 30–40 ft-lbs. No special tools needed.
• Use both washers: The 2-pack lets you replace washers on both blades of a dual-blade mower or keep a spare. Don’t reuse old, bent washers.
• Common gotcha: The washer is thin (about 1/16") and can be easily dropped or lost during blade changes. Work over a clean surface.
• Quality: Genuine EGO steel washer with a zinc coating resists rust better than painted alternatives. Holds up to normal mowing conditions.

Should You Buy It

If you own an LM2000-S, LM2020, or LM2020SP and your original blade washer is worn, bent, or missing, this is the exact OEM replacement you need. At $7.99 for two, it’s a cheap fix that prevents blade vibration and uneven cutting. Skip it if you have a different EGO model—fitment is model-specific.
