Lawn Mower Blades Mulching with 42 inch Decks Fits for 095100E701MA 4951003MA 495100MA for Murray 425000x8B 42508x92A 42571x31A 42586x8A, 2 PCS

What It Is

This is a set of two mulching blades designed for 42-inch cutting decks, intended to replace OEM blades on specific Murray riding mowers. They finely chop grass clippings for nutrient recycling, eliminating bagging or raking.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 42 inches (blade length is typically 20.5 inches, but measure your existing blade tip-to-tip). These blades fit Murray models 425000x8B, 42508x92A, 42571x31A, 42586x8A, and cross-reference OEM numbers 095100E701MA, 4951003MA, 495100MA. They are aftermarket replacements—not genuine Murray parts—so check your mower’s deck spindle pattern (usually a 5-point star or oval center hole). Also verify blade thickness (around 0.25 inches) and that the center hole diameter matches (typically 1 inch). If your deck uses a different mounting pattern or offset, these won’t fit.

Key Things to Know

• Quality: Aftermarket blades may be slightly lighter or thinner than OEM. For occasional residential use, they’re fine; for heavy commercial use, consider OEM.
• Installation: Easy DIY job—use a socket wrench and block the blade to prevent rotation. Always disconnect the spark plug first.
• Balance: Aftermarket blades often need balancing. Use a blade balancer to avoid vibration that can damage spindles.
• Mulching performance: Works best with dry grass and at slower speeds. Wet or tall grass will clump and require bagging.

Should You Buy It

If you own one of the listed Murray riding mowers with a 42-inch deck and need affordable, effective mulching blades for standard residential lawn care, these are a solid choice. For commercial use or if you prefer exact OEM specifications, stick with genuine Murray parts.
