8TEN LawnRAZOR Mower Blade for Murray Walk Behinds 22 inch Decks 71849E701 1101120E701MA 4714993MA MU671849 (Mulching)

What It Is

The 8TEN LawnRAZOR Mower Blade is a mulching blade designed for Murray walk-behind mowers with 22-inch cutting decks. It replaces OEM part numbers 71849E701, 1101120E701MA, and 4714993MA MU671849, and is intended for grass clipping recycling rather than bagging or side discharge.

Fitment & Compatibility

Before buying, check three things: deck size (must be exactly 22 inches), blade length (measure from center hole to tip—should match OEM), and center hole shape (typically a 5-point star or oval). This blade fits most Murray 22-inch walk-behinds from the 2000s onward, including models like 961140025, 961140026, and 961140027. It also fits some Craftsman, Bolens, and Yard Machines mowers that share Murray’s blade pattern. Verify your existing blade’s part number against the list above. If your blade has a different center hole or is longer/shorter, this will not fit.

Key Things to Know

• Mulching performance: The LawnRAZOR’s curved wings and sharpened edges create fine clippings, but only if your mower deck is clean and blades are sharp. Dull or dirty decks will clog.
• Installation difficulty: Easy—use a socket wrench (usually 5/8” or ¾”) and a blade removal tool or block of wood to prevent spinning. Torque to 35-45 ft-lbs.
• Common gotchas: The blade is slightly thicker than some OEM blades, which may require longer bolts (check included hardware). Also, it’s not for high-lift or bagging—using it for bagging will reduce airflow and leave clumps.
• Quality: Made from heat-treated steel, but some users report balancing issues out of the box. Always balance the blade before installing to avoid vibration.

Should You Buy It

Buy this if you have a Murray 22-inch walk-behind, want a solid mulching blade at a fair price, and don’t mind spending 10 minutes balancing it. Skip it if you need a bagging or high-lift blade, or if your deck size is off by even a quarter inch.
