8TEN LawnRAZOR Blade for John Deere JM26 JM36 JM46 JS26 JS36 JS46 22" Deck Walk Behind GX23522 (Mulching)

What It Is

The 8TEN LawnRAZOR Blade is a mulching blade designed for John Deere walk-behind mowers with a 22-inch deck. It replaces OEM blade part GX23522 and is intended for use on select JM and JS series models, specifically the JM26, JM36, JM46, JS26, JS36, and JS46.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 22 inches—this blade will not fit 21-inch or larger decks. It fits John Deere models JM26, JM36, JM46, JS26, JS36, and JS46 (all with 22-inch deck). It also fits the GX23522 deck assembly. Measure your blade length (22 inches) and center hole diameter (typically 7/8-inch on these models). Check that your mower uses a single blade (not a dual-blade system). This aftermarket blade replaces OEM part GX23522 but is not a direct OEM replacement.

Key Things to Buy

• Quality: Made from heat-treated steel with a mulching wing design for finer clippings. Users report good durability for residential use, but not as thick as some OEM blades.
• Installation: Easy swap—use a socket wrench to remove the center bolt. Always disconnect the spark plug and wear gloves. Torque to 40-50 ft-lbs.
• Common gotchas: The blade may need balancing out of the box (use a blade balancer). If your deck has a washout port, this blade’s shape may slightly reduce cleaning access.
• Performance: Best for mulching—not ideal for bagging or side-discharge. Expect a slightly higher cut quality but more frequent sharpening than standard blades.

Should You Buy It

If you own a compatible John Deere 22-inch walk-behind and primarily mulch leaves or grass, this blade offers good value at $28.95. It’s a solid budget alternative to OEM blades for residential use, but skip it if you need a bagging or high-lift blade, or if you mow very thick, wet grass regularly.
