Aeagle M143520 UC22010 Mower Blades for John Deere Z375R Z535M ZTRAK Z325E Z330M EZtrak Z425 Z435 X380 X435 X570 X710 X730 GX255 GX325 GX345 54'' Deck Zero Turn Mower Tractor, Medium Lift, Black

What It Is

This is a set of three medium-lift, black-coated mower blades designed for 54-inch zero-turn and lawn tractors. They are an aftermarket replacement for cutting grass on residential or commercial properties, offering a balance between bagging and mulching performance.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck and uses three blades. The Aeagle M143520 is an aftermarket match for OEM part numbers UC22010 and M143520, fitting John Deere Z375R, Z535M, Z325E, Z330M, Z425, Z435, X380, X435, X570, X710, X730, GX255, GX325, and GX345 models. Measure your existing blade’s length (should be ~20.5 inches), width (~2.75 inches), center hole diameter (~1 inch), and thickness to verify compatibility. If your mower uses a different blade pattern or has a 48-inch or 60-inch deck, these won’t fit.

Key Things to Know

• Medium lift design – Suitable for most grass types but may not handle thick, wet grass as well as high-lift blades.
• Black coating – Adds corrosion resistance but will wear off over time; inspect for rust after heavy use.
• Installation difficulty – Easy for DIYers with basic tools (socket wrench, torque wrench). Always torque to manufacturer specs (usually 70-90 ft-lbs) and use threadlocker if recommended.
• Balance check – Aftermarket blades can sometimes be slightly off-balance out of the box. Spin-test before installing to avoid vibration and deck damage.

Should You Buy It

Buy this set if you need an affordable, direct replacement for your John Deere 54-inch deck and you’re comfortable with basic blade installation. It’s a solid value for residential mowing, but if you demand maximum lift for bagging or have a commercial mowing operation, consider OEM or high-lift alternatives.
