Stens toothed lawn mower blade 21-3/4 in fits 22 in Husqvarna decks, 5-point star center OEM-fit replacement

Stens 302-604 is a 21-3/4" toothed replacement lawn mower blade made to match Husqvarna 580244002 fit and cutting profile for select 22" walk-behind mowers.

This high-strength Stens blade is engineered as a direct replacement for several Husqvarna 22" walk-behind models. It replicates the original cutting edge geometry and five-point star center hole to ensure secure mounting, consistent grass discharge and long service life. Before ordering, confirm your mower model and verify that your machine does not require a blade compatible with a Blade Brake Clutch (BBC) system.

Which mower models will this blade fit?

The blade is designed for Husqvarna walk-behind mowers that originally used part number 580244002. It fits multiple 22" deck models that use a 5-point star center mount. If your mower’s manual or old blade lists 580244002, this Stens 302-604 is a compatible replacement.

• Compatible with Husqvarna HU500F, HU550FH, HU675FE, HU700F, HU700L, HU725AWD, HU725F, HU800AWD
• Exact length: 21 3/4" to match 22" deck clearance
• Center mounting: 5-point star hole for secure fit
• Not compatible with mowers using Blade Brake Clutch (BBC)

How does the toothed design affect cutting performance?

The toothed profile helps lift and slice grass for improved clippings discharge in many turf conditions. It balances airflow and cutting action so you get even mulch and a cleaner stripe on typical lawn grasses. For heavy thatch or extremely tall weeds, occasional sharpening maintains peak performance.

• Toothed edge improves grass lift and discharge
• Works well for mulching and bagging depending on deck setup
• Maintains airflow for consistent cutting across the 22" deck
• Blade thickness supports durability under normal lawn conditions

What are the exact specifications I should check before buying?

Confirm the physical dimensions and mounting style on your existing blade or in your mower manual. Matching the length, width, thickness and center hole type avoids fitment and balance problems. Also ensure your mower does not rely on a Blade Brake Clutch system, which requires a different blade design.

• Length: 21 3/4" (matches 22" deck)
• Width: 2 1/2" and thickness: 0.137" for structural strength
• Center hole: 5-point star to align with mower spindle
• Not suitable for Blade Brake Clutch-equipped machines

Why choose a Stens replacement rather than a generic blade?

Stens manufactures replacement parts to meet or closely match OEM form, fit and function so you get reliable performance without overpaying for brand-only parts. Stens parts are packaged and labeled for dealer-level use and come with a one-year warranty for added confidence. Installing a matched replacement helps preserve mower balance and reduces vibration compared with ill-fitting aftermarket blades.

• Built to OEM-style dimensions and mounting geometry
• Backed by Stens one-year limited warranty
• Dealer-trusted quality and consistent labeling on packaging
• Reduces vibration and promotes even wear when properly installed

Who is this for? If you own a compatible Husqvarna 22" walk-behind mower that uses part number 580244002 and you need a robust, OEM-style replacement blade, the Stens 302-604 is made for routine maintenance and seasonal blade replacement. It’s suited for homeowners, landscapers and service technicians who want a durable toothed blade that fits the listed models and restores cutting performance. Always check fitment against your mower’s specifications and follow safe installation and blade-balance procedures.
