FourShow 36Pcs Endurance Blades Compatible with All Husqvarna Lawn Robots, Durable Titanium Replacement Blades, Including Screws with Safety Coating

What It Is

The FourShow 36-piece Endurance Blade set is a titanium-coated replacement blade kit designed for all Husqvarna robotic lawn mowers. It includes 36 blades and 36 safety-coated screws, intended for users who need frequent blade swaps on multiple robots or over a full season.

Fitment & Compatibility

This set is advertised as compatible with all Husqvarna robotic mowers (e.g., Automower 305, 310, 315, 420, 430X, 450X, 520, 550). Before buying, confirm your mower model—older or niche models may use different blade shapes or screw sizes. Measure an existing blade: these are typically 2.4 x 1.2 inches with a 4mm center hole. The included screws are M4 x 10mm with safety coating. If your mower uses a different screw thread (e.g., M5) or has a non-standard blade shape, they won’t fit. Cross-reference with Husqvarna OEM part numbers 579 88 06-01 or 579 88 06-02.

Key Things to Buy

• Titanium coating extends blade life 2-3x vs. standard steel, but dulls faster on sandy or rocky lawns—inspect regularly.
• Installation is easy: swap blades with a T20 Torx driver; no balancing required for robotic blades, but ensure screws are torqued to 3-4 Nm.
• Safety coating on screws reduces corrosion but may strip if over-tightened—use a torque wrench if possible.
• Gotcha: Some users report occasional blade thickness variation; check all 36 blades for burrs before installing to avoid poor cutting.

Should You Buy It

Buy this if you own multiple Husqvarna robotic mowers or want a season’s worth of replacements in one box. It’s a solid value for frequent blade changes on clean lawns, but skip it if your mower requires non-standard blades or you prefer OEM for zero-risk fit.
