SCITOO 095100E701 495100MA Mower Blades Fit for 42" Cut Murray

What It Is

The SCITOO 095100E701 / 495100MA mower blades are aftermarket replacement blades designed for 42-inch cutting deck Murray lawn tractors. They are meant for standard residential mowing on grass up to moderate thickness.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 42-inch cut Murray decks. Measure your deck width from blade tip to blade tip if unsure.
• OEM cross-reference: These replace Murray part numbers 095100E701 and 495100MA. Check your current blade’s part number or your owner’s manual.
• Measurements: Blade length should be 21 inches (center hole to tip), with a 5-point star center hole (1 inch diameter) and 0.25-inch thickness. Measure your old blade to confirm.
• Model compatibility: Fits many Murray riding mowers from the 2000s–2010s (e.g., 42-inch deck models like 42500x92A). Not for push mowers or other brands without adapter modifications.

Key Things to Know

• Quality vs. OEM: These are steel blades but may dull faster than Murray OEM blades. Expect 2–3 seasons of regular use with proper sharpening.
• Installation: Easy swap with a socket wrench and blade removal tool. Always disconnect the spark plug first. Torque the center bolt to 30–40 ft-lbs.
• Balance check: After installing, spin the blade by hand. If it wobbles or vibrates, you may need to balance it with a blade balancer (sold separately). Unbalanced blades damage the spindle.
• Common gotcha: The star center hole must align with the spindle’s star pattern. If your spindle uses a different shape (e.g., oval or hex), these won’t fit.

Should You Buy It

Buy these if you need a budget-friendly, direct-fit replacement for a 42-inch Murray deck and you’re comfortable with occasional sharpening and basic installation. Skip them if you want premium steel (e.g., mulching or high-lift blades) or if your spindle uses a non-star pattern. They’re a solid value for the price but not a long-term upgrade.
