Stens 340-210 Husqvarna 539113312 Hi-Lift Blade,Black

What It Is

The Stens 340-210 is a high-lift replacement blade for Husqvarna mowers, designed to increase airflow for superior grass clipping discharge and bagging performance. It’s ideal for residential or commercial mowers needing aggressive lift on tall or damp grass.

Fitment & Compatibility

• Primary fit: Husqvarna models using OEM part 539113312 (e.g., LTH series, some YTH/GT models with 42-inch or 48-inch decks). Stens 340-210 is a direct aftermarket replacement.
• Check before buying: Measure your blade length (20.5 inches center-to-center), center hole diameter (usually 1 inch), and drive hole pattern. Confirm your deck size and mower model in the Stens or Husqvarna parts list. Not universal—verify against your OEM blade part number.
• Cross-reference: Also fits some Poulan Pro, Craftsman, and AYP models with the same OEM number, but always double-check your specific deck.

Key Things to Know

• Quality: Stens is a reputable aftermarket brand; blade is heat-treated and coated for durability, but may be slightly thinner than OEM.
• Installation difficulty: Easy—use a socket wrench and block the blade to prevent spinning. Torque bolts to 40-50 ft-lbs (check manual). High-lift blades increase engine load; expect slightly lower runtime.
• Gotchas: High-lift design can cause clumping in dry, dusty conditions. Not for mulching—use only for bagging or side-discharge. Balance the blade after sharpening to avoid vibration.
• Price vs OEM: At ~$20, it’s 30-50% cheaper than Husqvarna OEM, but some users report shorter lifespan.

Should You Buy It

Buy this blade if you own a compatible Husqvarna mower and need aggressive bagging performance on tall or wet grass without paying OEM prices. Skip it if you mulch, have a smaller deck, or prioritize long blade life—consider a standard-lift or OEM blade instead.
