Lawnmower Blade for Stihl RMA 2

What It Is

This is a replacement blade designed specifically for the Stihl RMA 2 series of battery-powered walk-behind mowers. It’s intended for standard residential or commercial grass cutting, not mulching or bagging unless specified.

Fitment & Compatibility

Before buying, verify your mower’s exact model number (e.g., RMA 2, RMA 2.1, RMA 2.2) – not all RMA 2 variants share the same blade. Measure the existing blade’s length (approx. 18-21 inches depending on deck size) and center hole diameter (typically 7/8 inch or 1 inch). This aftermarket blade may differ slightly from OEM Stihl part numbers, so cross-check the blade’s part number against Stihl’s original (often listed in your manual or on the old blade). Also confirm the blade’s thickness (usually 0.125-0.156 inches) to ensure it fits the spindle and bolt.

Key Things to Know

• Price point: At $126.31, this is significantly more expensive than most aftermarket blades (usually $20-$40) – verify if it’s a genuine Stihl part or a premium aftermarket option.
• Installation: Requires a socket wrench and a blade stop tool (or wooden block) to prevent spinning. Torque the center bolt to 35-45 ft-lbs per Stihl specs.
• Sharpness: The single review suggests high quality, but check if the blade comes pre-sharpened or needs sharpening before first use.
• Balance: Always balance the blade after installation to avoid vibration and spindle damage. Use a blade balancer or a nail-in-the-wall trick.

Should You Buy It

This blade is only for Stihl RMA 2 owners who need a direct replacement and are willing to pay a premium for what appears to be a high-quality option. If you’re on a budget or prefer OEM parts, check Stihl dealer pricing first – this may be overpriced for the same thing. Skip it if your deck size or model doesn’t match exactly.
