MaxPower 561809B 3-Blade Set for 54" Cut John Deere Replaces M115496

What It Is

This is a set of three replacement blades for 54-inch cut John Deere lawn tractors and zero-turn mowers. It’s designed for medium-to-heavy residential mowing and light commercial use, offering a budget-friendly alternative to OEM blades.

Fitment & Compatibility

Before buying, measure your existing blades: each blade must be 18.5 inches long, with a 1-inch center hole and a 0.5-inch diameter pin hole (for the anti-scalp wheel pin). This set directly replaces John Deere part M115496 and fits models like the X540, X584, X590, X720, X724, X728, Z445, Z465, Z645, Z665, Z925A, and Z950A. Always verify your deck size is exactly 54 inches—blades for 54-inch decks are not interchangeable with 48-inch or 60-inch decks. Check your owner’s manual or the existing blade’s part number to confirm.

Key Things to Buy

• Quality: Made from 7-gauge heat-treated steel, these are durable enough for thick grass and occasional debris, but not as hard as OEM or premium aftermarket blades. Expect slightly shorter edge life if you hit rocks or roots often.
• Installation: Moderate difficulty. You’ll need a socket wrench, torque wrench (recommended 40-60 ft-lbs), and a blade removal tool or block of wood to hold the blade. The pin hole alignment can be fiddly—use a punch if needed.
• Common gotchas: These blades are not “mulching” or “high-lift”—they are standard lift blades. If you need more suction or finer clippings, look for a dedicated mulching set. Also, always replace all three blades at once to avoid imbalance.
• Fitment note: The anti-scalp pin hole is present but not used on all models; if your deck lacks the pins, the hole won’t affect performance.

Should You Buy It

Buy this set if you have a compatible 54-inch John Deere and want a reliable, affordable replacement for general mowing without paying OEM prices. Skip it if you need high-lift bags or premium edge retention for sandy or rocky lawns—invest in a thicker aftermarket or OEM set instead.
