22" Mulching Mower Blades for John Deere 42 Inch Freedom Deck, Replacement for AM130172 AM126023 AM128013, Butterfly Center Hole 2PCS with Bolts and Washers

What It Is

A pair of 22-inch mulching blades designed for John Deere 42-inch Freedom decks (model year 2005 and later). These replace OEM part numbers AM130172, AM126023, and AM128013, and include bolts and washers for a direct swap. They are intended for mulching—cutting grass into fine clippings that decompose quickly—rather than bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm your mower deck is a 42-inch Freedom (not Edge, Accel, or other decks). Measure the blade length from tip to tip—must be exactly 22 inches. The center hole is a butterfly (oblong) shape, not a standard round hole. Check that your spindle uses a 5/8-inch hex bolt (included). These blades fit most John Deere models with the 42-inch Freedom deck, such as X300, X320, X330, X350, X370, X380, X390, LA105, LA115, LA125, LA135, LA145, LA155, L100, L110, L118, L120, L130, D100, D105, D110, D120, D125, D130, D140, D155, D160, D170, S240, and Z245. If your deck is a 42-inch Edge or Accel, these will not fit.

Key Things to Know

• Quality: These are aftermarket blades, not OEM John Deere. They are made from hardened steel and should match OEM durability for typical homeowner use, but may not hold an edge as long in heavy or sandy conditions.
• Installation: Easy—remove the old blade bolt with a wrench, swap blades, and torque the bolt to 55-70 ft-lbs. Use the included bolts and washers; do not reuse old hardware. Ensure the blade is oriented with the lift wing pointing up toward the deck.
• Common gotcha: The butterfly center hole must align with the spindle’s drive pin. If your spindle has a round hole or a different pin shape, these blades won’t mount. Also, these are mulching blades—if you want bagging or side-discharge, choose a different style.
• Price vs. OEM: At $58.99 for a pair with hardware, these are cheaper than John Deere OEM blades (typically $35-45 each). Good value if you mulch regularly and replace blades annually.

Should You Buy It

Buy these if you own a John Deere with a 42-inch Freedom deck, mulch your lawn, and want a cost-effective, bolt-on replacement that includes hardware. They are a solid choice for homeowners who mow weekly and replace blades once a season. If you need bagging performance or have a different deck type, look elsewhere.
