EGO Power+ 2827669001 Upper Blade for LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, and LM2156SP 21" Select Cut Mowers

What It Is

The EGO Power+ 2827669001 Upper Blade is a replacement blade for the dual-blade “Select Cut” system on 21-inch EGO mowers. It works in tandem with the lower blade to create a finer clip and better mulching, designed specifically for EGO’s LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, and LM2156SP models.

Fitment & Compatibility

• Deck size: 21 inches only. Do not use on 20-inch or 22-inch EGO decks.
• Model match: Confirmed for LM2130, LM2133, LM2130SP, LM2135SP, LM2150SP, LM2156SP. Check your model number on the mower deck or manual—other 21-inch EGO models (e.g., LM2100 series) use a different blade set.
• Upper vs. lower: This is the upper blade (shorter, curved). The lower blade (longer, straight) is sold separately (part 2827668001). You need both for the Select Cut system to work.
• OEM vs. aftermarket: This is OEM EGO. Aftermarket equivalents exist but may not match the exact curvature or balance. Stick with OEM for warranty and performance.
• Measurements: Blade length ~20.5 inches, center hole 1 inch diameter, three mounting holes on a 3.25-inch bolt circle. Verify your existing blade matches before ordering.

Key Things to Know

• Installation difficulty: Easy. One bolt per blade, use a socket or wrench (13mm or 1/2 inch). Torque to 30-35 ft-lbs—don’t overtighten.
• Common gotcha: The upper blade is thinner and lighter than the lower. Mixing them up will cause vibration and poor cut. Mark which is which before removing.
• Quality: EGO’s OEM blade is heat-treated steel with a precision edge. Lasts 1-2 seasons depending on grass type and debris. Dull blades strain the motor and battery.
• Sharpening: You can sharpen it, but the dual-blade system relies on precise balance. Replacing both blades at once is recommended for even wear.

Should You Buy It

This is the correct OEM replacement for the upper blade on EGO’s 21-inch Select Cut mowers. If you own one of the listed models and your upper blade is worn, chipped, or bent, buy it. It’s simple to install, restores mulching quality, and keeps your warranty intact. For non-Select Cut models or different deck sizes, look elsewhere.
