4951003MA Mower Blades Compatible with Murray 42" Deck Lawn Tractor, Mulching Blades 95100E701 Fit for Murray 425303x92B 42571x31A 425000x8B Mowers, Replace 095100E701 0951000MA 495100, (2 Pack)

What It Is

This is a 2-pack of aftermarket mulching blades designed for 42-inch cutting decks on Murray lawn tractors. They replace OEM part numbers 095100E701, 0951000MA, and 495100, and are intended for mulching (fine grass clipping) rather than bagging or side discharge.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck (not 38", 46", or 48"). These blades fit specific Murray tractor models including 425303x92B, 42571x31A, and 425000x8B. Check your mower’s model number (on the frame or under the seat) against the list. The blade length is approximately 21 inches (center hole to tip), with a 1-inch diameter center hole and a 5-point star pattern drive. If your deck uses a different mounting pattern or has a smaller/larger center hole, these won’t fit. OEM equivalents are Murray 095100E701, 0951000MA, and 495100.

Key Things to Know

• Mulching vs. standard blades: These have a more curved, serrated edge to cut grass finer. Do not use for bagging—they’ll clog the chute.
• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque blade bolts to 70–90 ft-lbs (check your manual).
• Common gotchas: Aftermarket blades may be slightly thinner or less balanced than OEM. Always balance them on a blade balancer before installing. Also, verify the deck spindle isn’t bent—worn spindles can cause vibration.
• Durability: Made from heat-treated steel, but not as hard as OEM Murray blades. Expect to sharpen or replace after 10–15 hours of heavy use.

Should You Buy It

Yes, if you need a budget-friendly mulching blade set for a compatible Murray 42" deck tractor and don’t mind occasional balancing or slightly shorter lifespan than OEM. It’s a solid value for homeowners with medium-sized lawns (under 1 acre) who want fine clippings for natural fertilization. Skip it if you bag regularly or have a different deck size or brand.
