15 Count Robotic Lawn Mower Blades (1 inches, For Husqvarna - Endurance, Black Titanium Coated, Doubles Cutting Area)

What It Is

This is a 15-pack of black titanium-coated robotic mower blades designed for Husqvarna Automower models. Each blade is 1 inch long and shaped to double the effective cutting area per pass compared to standard blades, making them ideal for maintaining fine turf on medium to large lawns.

Fitment & Compatibility

• Exact models: Fits Husqvarna Automower 305, 310, 315, 315X, 420, 430X, 440, 450X, 520, 550, and 535 AWD. Also compatible with the Endurance series (e.g., 415X, 435X AWD).
• Measurement check: Blade length must be exactly 1 inch (25.4 mm) – measure your current blades; these are shorter than some universal blades.
• OEM cross-reference: Replaces Husqvarna part numbers 589 62 12-01, 589 62 12-02, and 589 62 12-03.
• Mounting pattern: Three-hole design with 6 mm center hole – verify your mower’s blade disc uses this pattern (most Husqvarna discs do).
• Aftermarket note: Not OEM, but black titanium coating is a premium upgrade over standard steel – won’t affect fit, but may last longer.

Key Things to Know

• Cutting area boost: The “doubles cutting area” claim means the blade’s geometry cuts on both forward and reverse passes – you’ll see fewer missed strips, but only on flat turf.
• Installation: Easy – swap blades one at a time using a T20 Torx screwdriver. No balancing required (blades are small and symmetrical).
• Coating benefit: Black titanium reduces rust and friction; expect 2–3x longer life than plain steel in damp grass.
• Common gotcha: These are not for Husqvarna’s older 260/265 models or any non-Husqvarna robot (e.g., Worx, Landroid). Always check blade disc thickness – if your disc is warped, new blades won’t cut evenly.

Should You Buy It

Buy this if you own a compatible Husqvarna Automower and want a cost-effective bulk pack with better durability and cut quality than standard steel blades. It’s a solid upgrade for owners of medium-to-large lawns who mow frequently and value longer blade life over OEM pricing. Skip it if you have a smaller robot mower or a non-Husqvarna brand.
