ACEBRI Mower Blades 54 '' Fit for John Deere M115496, GY20569, for John Deere 325, 335, 345, 355D, 425, 445, 455, F725, G100, LX288 Mower Blades 3Pack

What It Is

These are aftermarket 54-inch mower blades designed for multiple John Deere lawn and garden tractors. They are sold as a 3-pack, intended for use on decks requiring three blades (typically 54-inch cutting decks). The blades are replacements for OEM parts M115496 and GY20569.

Fitment & Compatibility

Before buying, verify three things: your deck size must be exactly 54 inches, your tractor must be one of the listed models (325, 335, 345, 355D, 425, 445, 455, F725, G100, LX288), and your deck must use three blades. These are aftermarket, not OEM John Deere parts, so measure your existing blade length, width, center hole diameter, and thickness to confirm they match the ACEBRI blades. Check that the blade shape (e.g., high-lift or standard) matches your mowing conditions—these appear to be medium-lift blades suited for general mulching and bagging.

Key Things to Know

• Quality vs OEM: At $32.99 for a 3-pack, these are significantly cheaper than John Deere OEM blades. Expect shorter edge retention and less balanced sharpness out of the box.
• Installation: Easy if you have a socket wrench and jack stands. Torque bolts to 70-90 ft-lbs. Always use new lock washers.
• Common gotcha: Some users report the blades are slightly thinner than OEM, which can cause vibration or uneven cut if the deck isn’t perfectly level. Check deck spindle bearings before installing.
• Sharpening: They’re not pre-sharpened as aggressively as OEM. You may need to file the edges before first use for best cut quality.

Should You Buy It

This is a budget-friendly option for owners of compatible John Deere tractors who need a quick replacement for standard residential mowing. It’s not ideal for commercial use or rough terrain where blade durability matters. If you’re a homeowner with a 54-inch deck and don’t mind slightly shorter lifespan, this 3-pack offers solid value.
