8TEN LawnRAZOR high-lift mower blades for John Deere TCU15881/M128485 — 3-pack, 21 1/16" x 3" steel

8TEN LawnRAZOR high-lift replacement mower blades are a 3-pack of 21 1/16" x 3" steel blades engineered to fit John Deere OEM numbers TCU15881/M128485 and deliver strong lift and consistent cutting performance.

These blades are made to match the mounting and dimensions used by many John Deere compact tractors, riding mowers, and zero-turn models. Each blade measures 21 1/16" long, 3" wide, with a 7/8" center hole and 0.25" thickness, so they slip into the same hardware and spindles as the referenced OEM parts. The set of three lets you refresh multiple decks or keep replacements on hand to minimize downtime during the mowing season.

How will these blades fit my John Deere machine?

These 8TEN LawnRAZOR blades are compatible with the listed John Deere OEM part numbers and a wide range of models.

What cut quality and deck performance can I expect?

These are high-lift blades designed to create strong airflow under the deck, lifting grass up for a cleaner, more uniform cut and better bagging or side discharge. They help move clippings efficiently through the deck and into the collector on machines equipped for bagging. Expect restored deck performance when replacing worn or bent blades.

• High-lift profile increases airflow for improved grass lift
• Sharper, consistent cutting edges for even results across the swath
• Helps with bagging and efficient discharge of clippings
• Set of three reduces the chance of uneven wear across the deck

How durable and easy to install are these blades?

Constructed from stamped and heat-treated steel, these blades balance hardness for edge retention with flexibility to resist cracking. Installation is straightforward: support the deck, remove mounting hardware, swap the blades one at a time, and torque fasteners to your mower manufacturer's specs. Replace any damaged mounting hardware for a secure fit.

• Heat-treated steel for edge holding and durability
• Standard 7/8" center hole fits common spindles and bolts
• Swap-in replacement — no modifications required for matching decks
• Sold as a 3-pack to handle multi-blade decks or spare needs

Who is this for: The 8TEN LawnRAZOR 3-pack is for owners of John Deere compact tractors, lawn tractors, and zero-turn mowers that list TCU15881 or M128485 as compatible blade references, and for landscapers or homeowners who want ready spare blades. Choose this set if your goal is to restore deck lift and cutting uniformity with blades that match OEM dimensions, or if you maintain multiple machines and prefer having replacements on hand to reduce downtime.
