What It Is

This is a Stens aftermarket lawn mower blade (part 305-457) designed for 40-inch cutting decks on specific Ariens and Woods models. It’s a direct replacement for OEM blades used in residential or light commercial mowing.

Fitment & Compatibility

Before buying, confirm your deck is 40 inches (not 42 or 48) and that you need two blades to cover the full width. Cross-reference your existing blade’s part number against these OEM numbers: Ariens 03607059, 03624700, 03624751, 03624759, 3607059, 36247, 3624751, 3624759, 03624751, 03624751KT. Measure your blade’s length (should be ~20 inches), center hole diameter (typically 1 inch), and thickness (usually 0.25 inches). Stens is a well-known aftermarket brand, but verify the blade shape matches your deck’s discharge path—some aftermarket blades have different lift profiles that can affect bagging or mulching.

Key Things to Buy

• Quality: Stens blades are heat-treated and hardened, comparable to OEM for durability. Expect similar lifespan under normal use.
• Installation: Easy bolt-on for most DIYers—use a torque wrench (typically 40–60 ft-lbs) and replace any worn bolts or washers. Always sharpen new blades before first use.
• Common Gotchas: Some users report these blades are slightly thinner than OEM, which can cause vibration on older decks. Check your spindles for play before installation. Never mix with other blade types on the same deck.
• Cost vs. OEM: At $23.73 for a pair, Stens is often 30–50% cheaper than genuine Ariens/Woods blades, but may not last as long in heavy-duty or commercial use.

Should You Buy It

If you have a 40-inch Ariens or Woods deck and need a reliable, budget-friendly replacement for standard residential mowing, this Stens blade is a solid choice. It’s not for high-abrasion environments (e.g., sandy soil) or extreme commercial use. For occasional homeowners who sharpen annually, it’s a smart value buy.
