M METERXITY 9-Pack Robotic Lawnmower Replacement Blades, 49x19x0.8mm Stainless Steel Robotic Lawn Mower Accessories with Screws for Outdoor, Robust Mowing Spare Parts Blades [Silver Tone]

What It Is

This is a 9-pack of replacement stainless steel blades (49x19x0.8mm) for robotic lawnmowers, designed for light-duty trimming and mulching. Comes with screws for quick swaps.

Fitment & Compatibility

Measure first: The critical dimension is 49mm length, 19mm width, 0.8mm thickness—this is a common size for many budget and mid-range robomowers (e.g., Worx Landroid, Husqvarna Automower, and generic units).
Check bolt pattern: These blades use a single center screw (included), but verify your mower’s blade mounting hole diameter and screw thread pitch. Many robotic mowers use M5 or M6 screws.
Brand-specific: Not OEM for any major brand—these are universal replacements. If your mower uses a proprietary blade shape or locking mechanism, they won’t fit.
Deck clearance: The 0.8mm thickness is standard; thicker blades may not spin freely in tight decks.

Key Things to Know

• Stainless steel quality: These are 304 stainless—decent corrosion resistance but softer than hardened steel. They’ll dull faster on thick or wet grass.
• Installation: Simple—remove old blade, swap with new one using the included screws. No special tools needed, but use a screwdriver to avoid stripping.
• Sharpness: Arrives sharp but not razor-edged. Expect to replace every 2-4 months depending on use and debris.
• Screw quality: Included screws are basic; consider using thread-locker to prevent loosening during mowing.

Should You Buy It

Good for owners of generic or budget robotic mowers needing a cheap, quick blade refresh. Not ideal for heavy-duty use or premium brands with specific blade designs (e.g., Husqvarna’s X-Line). If your mower uses standard 49x19mm blades and you want a low-cost 9-pack, this works.
