KANXAJJY Toothed Mulching Mower Blades for John Deere 54" Deck — 3-Pack, 19" x 3", Powder-Coated

KANXAJJY's three-piece set of M143520 toothed mulching blades replaces John Deere M145516 and M152726 to restore efficient mulching on 54" deck tractors.

These replacement blades are designed to fit a wide range of John Deere lawn and zero-turn tractors and compact utility models. Manufactured from high-grade steel with a protective powder coat, each blade measures 19" long, 3" wide and 0.25" thick, with a 13/16" center hole. The toothed mulching profile helps re-cut clippings repeatedly so they break down faster and disperse more evenly back into the turf.

Will these blades fit my John Deere mower?

They are engineered to match several popular John Deere OEM part numbers and many tractor models, but confirm the blade center-hole shape and deck size before ordering. If your mower uses John Deere M143520, M145516 or M152726 replacements for a 54" deck, these blades are compatible.

• Replaces OEM: John Deere M143520, M145516, M152726
• Fits ZTRAK and EZTRAK series including Z375R, Z525E, Z535M, Z540M, Z425, Z435, Z445
• Also fits select John Deere compact tractors and lawn tractors such as X340, X380 and GX series
• Confirm center hole 13/16" and 54" deck prior to purchase

How do these toothed mulching blades improve cut quality?

The serrated, multi-edge design re-touches grass clippings multiple times, producing finer mulch that settles into the turf more evenly. That reduces visible clippings and helps the lawn recycle nutrients when used as part of a regular mowing routine.

• Toothed profile for repeated clipping and finer mulch
• Powder-coated finish reduces rust and maintains sharpness longer
• Standardized dimensions for predictable balance and performance

What are the construction and durability features?

Each blade is stamped from high-grade steel and treated with a durable powder coating to resist corrosion and abrasion. The 0.25" thickness and balanced length help prevent premature flexing while preserving cutting edge life under normal use.

• Material: high-grade steel with powder-coated surface
• Dimensions: 19" length, 3" width, 0.25" thickness
• Package: set of three blades ready for 54" decks

How do I install and maintain these replacement blades?

Installation follows the same steps as OEM blade changes: disconnect spark, raise deck, remove blade bolt, swap blades, and torque to manufacturer specification. Routine maintenance includes inspecting for nicks, maintaining sharp edges, and keeping mounting holes and hardware free of debris.

• Always disconnect spark or power before servicing
• Check blade orientation and torque bolts to OEM specs
• Sharpen or replace blades when edges are nicked or bent

Who this is for: This three-pack is ideal for homeowners and small commercial operators who maintain John Deere mowers with a 54" deck and want a durable, toothed mulching option that replaces common OEM numbers. It suits users seeking straightforward bolt-on compatibility, improved mulching performance, and corrosion resistance without custom modifications. Verify your deck size and center-hole fit to ensure a correct match before purchase.
