What It Is

This is a direct replacement 22-inch lawn mower blade designed for MTD walk-behind mowers built from 1996 onward. It cuts grass on standard residential properties and replaces multiple OEM numbers including 490-100-M087, 742-0642, 742-0642A, 942-0642, and 942-0642A.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This blade is exactly 22 inches long. Measure your current blade tip-to-tip. It fits only 22-inch cutting decks.
• Mounting pattern: Center hole is 7/8-inch diameter with a 5-point star pattern. Measure your blade’s center hole and spindle pattern. This blade won’t fit round or 4-point mounts.
• Model range: Works on MTD walk-behinds from 1996 to present. Common brands include Cub Cadet, Troy-Bilt, Yard Machines, Yard-Man, and Bolens with 22-inch decks. Check your mower’s model number against Stens cross-reference or MTD OEM lists.
• OEM vs aftermarket: Stens is a quality aftermarket brand. It matches OEM specs but is not a genuine MTD part. Fine for most users, but warranty purists may want OEM.

Key Things to Know

• Quality: Stens blades are heat-treated and hardened. They’re comparable to OEM in durability. Expect 20–30 hours of cutting before dulling, depending on grass and debris.
• Installation difficulty: Easy. Remove spark plug wire, tilt mower, unbolt old blade (left-hand thread on some MTD models), and install new one with sharp edge facing up. Torque bolt to 35–50 ft-lbs.
• Common gotcha: Many MTD blades have a “sail” (lift) that can be bent during shipping. Inspect blade for flatness before installing. If bent, return it.
• Balance: Stens blades are pre-balanced. Still, it’s smart to check balance on a blade balancer after installation to avoid vibration.

Should You Buy It

If you have an MTD 22-inch walk-behind from 1996 or newer and want a reliable, affordable replacement without paying OEM markup, this blade is a solid choice. It’s well-built, fits correctly, and has good reviews. Skip it if you need a different length or mounting pattern, or if your mower is under warranty and requires genuine MTD parts.
