4951003MA Mower Blades Compatible with Murray 42" Deck Lawn Tractor, Mulching Blades 95100E701 Fit for Murray 425303x92B 42571x31A 425000x8B Mowers (2 Pack)

What It Is

This is a 2-pack of aftermarket mulching blades (part #4951003MA) designed for Murray 42-inch deck lawn tractors. They replace OEM blade 95100E701 and are intended for cutting grass into fine clippings that decompose quickly, eliminating the need for bagging.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 42-inch cutting deck. Measure your deck width—blades are 21 inches long (center hole to tip).
• Model compatibility: Fits Murray models 425303x92B, 42571x31A, 425000x8B, and others using OEM blade 95100E701. Check your mower’s model number (stamped under seat or on frame).
• Blade measurements: Center hole diameter is 1 inch, with a 5-point star drive pattern. If your spindle uses a different shape (e.g., oval or keyed), these won’t fit. Measure your old blade’s length, hole size, and drive pattern.

Note: These are aftermarket, not OEM Murray. They may differ slightly in thickness or balance—always test spin by hand after install.

Key Things to Know

• Mulching vs. standard: These have a curved, high-lift design with extra cutting edges. They work best when the deck is clean and grass is dry. Wet or tall grass will clog.
• Installation difficulty: Easy—just a socket wrench and blade removal tool. Torque blade bolts to 70-80 ft-lbs (check your manual). Use thread locker if bolts don’t have nylon inserts.
• Common gotcha: The star drive pattern may fit snugly or loosely on some spindles. If it wobbles, the blade could come loose. Tighten to spec and re-check after 1 hour of use.
• Balance: Aftermarket blades can be slightly out of balance. If you feel vibration, remove the blade and balance it on a nail or use a blade balancer—file the heavy side.

Should You Buy It

If you own a Murray 42-inch deck tractor and want an affordable mulching upgrade without paying OEM prices, this is a solid choice. The 4.7-star rating indicates good quality for the price, but double-check your exact model number and spindle pattern first. Not for bagging or side-discharge use.
