What It Is

This is a 3-pack of 54-inch deck mower blades designed for zero-turn and compact utility tractors from John Deere. They replace OEM part numbers M143520, M145516, and M152726, and are intended for cutting grass on residential or light commercial properties.

Fitment & Compatibility

Before buying, confirm your mower deck measures exactly 54 inches from blade tip to blade tip. These blades fit John Deere ZTrak models Z375R, Z525E, and Z535M, plus compact utility tractors 1023, 1025R, 1026R, GX255, GX335, GX345, X340, X380, and X394. Also compatible with OEM part numbers M143520, M145516, M152726, and 396-719. Measure your existing blade length (should be 20.5 inches) and center hole diameter (1 inch) to verify. Check your deck’s blade orientation—some John Deere decks require specific blade indexing for proper overlap.

Key Things to Know

• Quality: Aftermarket blades at this price point are generally medium-carbon steel. They’ll cut well but may dull faster than OEM or premium high-lift blades, especially in sandy or rocky conditions.
• Installation: Straightforward if you have a socket set and a torque wrench. Tighten blade bolts to 70-90 ft-lbs. Mark blade orientation before removal to avoid imbalance.
• Common gotchas: The 3-pack includes three identical blades; some John Deere decks use two different blade designs (e.g., one with a different angle or lift). Verify your deck uses three identical blades before buying.
• No hardware included: You’ll need to reuse or replace the blade bolts and washers separately.

Should You Buy It

If you own one of the listed John Deere models and need a budget-friendly replacement that fits correctly, this 3-pack is a good value. It’s best for homeowners who cut on clean, well-maintained lawns and don’t mind replacing blades more often than with premium options. Avoid if you have heavy-duty commercial use or need high-lift blades for wet/dense grass.
