Robotic Lawn Mower Blade (15, for Husqvarna - Monster 43MM) Also for Gardena McCulloch Robotic Lawnmower Mowing Robo Robot Accessories Replacement for 315 430 435 450 and Many Others

What It Is

This is a replacement blade set for robotic lawn mowers, specifically the 43mm “Monster” style blade. It’s designed for Husqvarna, Gardena, and McCulloch automowers, suitable for frequent trimming and mulching in residential lawns.

Fitment & Compatibility

Check these before buying:

• Blade length: 43mm (1.7 inches) – measure your current blade to confirm. This is a standard size for many robotic mowers, but not all.
• Model compatibility: Fits Husqvarna 315, 430, 435, 450 series and many Gardena/McCulloch models. Verify your mower’s model number on the underside or in the manual.
• OEM vs aftermarket: This is a Husqvarna-branded part, so it’s OEM quality. Aftermarket blades may vary in hardness or balance.
• Mounting hole: Ensure the center hole matches your mower’s spindle. This blade uses a standard 6mm hole – common, but double-check.

Key Things to Know

• Installation difficulty: Easy – typically a single screw holds each blade. Use a Torx T20 or T25 bit (check your mower). No special tools required.
• Durability: Expect 2-4 months of regular use before dulling. Replace sooner if you hit rocks or roots.
• Common gotcha: Robotic mower blades are not sharp like traditional blades – they’re dulled on purpose for safety. Don’t try to sharpen them; just replace.
• Quantity: Sold as a set of 15 blades – enough for multiple replacements. Store unused blades in a dry place to prevent rust.

Should You Buy It

If you own a compatible Husqvarna, Gardena, or McCulloch robotic mower and want a reliable, OEM-quality replacement blade set at a fair price, this is a solid choice. It’s especially good for frequent mowing schedules where blade wear is high. Avoid if your mower uses a different blade length (e.g., 40mm or 45mm) or if you need a smaller quantity.
