Murray 42 3-in-1 Combo Lawn Mower Mulching Blade Set 495100

What It Is

This is a 3-in-1 combo blade set for Murray 42-inch deck lawn tractors, designed for mulching, bagging, and side-discharge cutting. It replaces OEM part 495100 and is ideal for homeowners needing one blade set to handle all three functions without swapping blades.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck—this set includes three blades, each 14.75 inches long with a 1-inch center hole and 0.25-inch thick steel. It fits most Murray models (e.g., 42500x92, 42507x92) and some Craftsman, Husqvarna, and Poulan Pro tractors with the same spindle pattern. Check your deck’s blade mounting holes: these use a 5-point star pattern (common on Murray). Measure your old blade’s length and hole diameter; if they match, it’s likely compatible. Avoid assuming universal fit—cross-reference your mower’s model number with Murray’s 495100 list.

Key Things to Know

• Quality: Medium-carbon steel with a painted finish; good for residential use but may dull faster than OEM on heavy-duty or rocky terrain. Sharpening is possible but not recommended more than once.
• Installation: Straightforward—remove the old blades (use a block of wood to secure the deck), install these with the curved edge facing upward toward the deck. Torque bolts to 70-90 ft-lbs; over-tightening can strip spindles.
• Common Gotchas: The center hole is 1 inch, but some older Murray decks use a 7/16-inch hole—measure first. The set includes three blades, but if your deck has two spindles (rare for 42-inch), you’ll have an extra. Balance each blade after installation by hanging it on a nail; a heavy side means you need to file the opposite edge.
• Performance: Mulching is decent for dry grass but clumps in wet conditions. For bagging, ensure the chute is clear; side-discharge works best with the included adapters (not always included—check packaging).

Should You Buy It

If you own a Murray 42-inch deck and want a single, affordable blade set that handles mulching, bagging, and discharging without switching blades, this is a solid choice for regular lawn upkeep. It’s not for commercial use or rough terrain, but for typical residential yards, it delivers good value at $38.27. Just double-check your deck’s hole size and spindle count before buying.
