MaxPower 561814B 3 Blade Set for Many 48 in. Cut John Deere Mowers Replaces OEM #'s M127500 and M145476, Black

What It Is

This is a set of three replacement blades for 48-inch cut John Deere lawn tractors, designed to fit decks requiring OEM #M127500 or #M145476. It’s a direct aftermarket alternative for standard mulching or bagging mowing.

Fitment & Compatibility

Deck size: Only for 48-inch cut decks. Measure your existing blades – these are 18.5 inches long, 2.5 inches wide, with a 1-inch center hole and 0.5-inch offset.
Models: Fits many John Deere 100, 300, 400, and 500 series (e.g., D100, X300, X500) with 48-inch decks. Check your deck model number (e.g., 48C, 48D).
OEM cross-reference: Replaces John Deere M127500 and M145476. Not compatible with M155179 or other blade lengths.
Aftermarket note: MaxPower blades may have slightly different lift profile than OEM – fine for most grass, but may reduce bagging performance in wet or thick conditions.

Key Things to Know

• Quality: Heat-treated steel, balanced, and pre-sharpened. Edge holds well for 15-20 hours of normal use.
• Installation: Easy DIY – use a socket wrench and blade removal tool (or block of wood). Torque bolts to 40-50 ft-lbs. Always sharpen new blades before first use for best cut.
• Gotcha: These are not universal – won’t fit 54-inch or 60-inch decks. Verify your deck’s spindle bolt pattern (usually 2.25-inch spacing).
• Common issue: Some users report needing to re-balance after install due to slight weight variation – worth checking with a blade balancer.

Should You Buy It

If you own a 48-inch John Deere with M127500/M145476 blades and want a reliable, budget-friendly replacement that performs well for dry grass and occasional mulching, this set is a solid choice. For heavy wet grass or professional landscaping, consider OEM blades for more consistent lift and bagging.
