John Deere mower blades 2-pack for 38" decks M82408 — OEM carbon-boron steel, low-lift

John Deere Original Equipment 2 Blades (M82408) are OEM low-lift replacement blades made from carbon-boron steel for long-lasting sharpness and precise cut on compatible 38" decks.

These two genuine John Deere replacement blades are designed to restore cutting performance on a wide range of compact tractors, lawn tractors and front mowers that use 38" mower decks. As an Original Equipment Manufacturer (OEM) item, they match the specifications of the factory parts for reliable fit and balanced operation. Built with a carbon-boron steel blend, these blades resist breakage and hold an edge longer than ordinary stamped blades.

Which John Deere models and decks will these blades fit?

These M82408 blades fit many John Deere 38" mower decks and select 42" and 48" convertible applications listed for compatibility. They replace several OEM part numbers, making them a direct swap for tractors that specify those numbers.

• Compatible with 38" decks used on 108, 111, 112L, 116, 130, 160, 165, 170 series and more.
• Also fits LT150/155/160/166/180 series, LX170 series decks, STX and SRX front mowers and select RX models.
• Cross-references include M8240, AM121287, AM10094 and M131157.
• Check your owner’s manual or deck tag for exact part number match before ordering.

How do these blades improve cutting performance?

John Deere’s carbon-boron steel formulation increases hardness so the blades keep a sharp edge longer and resist chipping. Because they’re OEM-spec, they maintain the deck’s original balance and blade pitch for even grass discharge and a clean cut.

• Harder steel retains edge and reduces frequency of sharpening.
• Low-lift design minimizes suction—good for fine clipping and bagging setups.
• OEM fit preserves deck balance and reduces vibration when installed correctly.
• Two-blade pack makes it convenient to replace both blades at once for matched blade geometry.

What should I consider when installing and maintaining these blades?

Always follow safe installation steps: disconnect spark plug, remove old blades, and torque hardware to John Deere specifications. Periodic inspections and proper sharpening preserve cutting quality and extend blade life.

• Verify blade orientation—cutting edge and lift face must match deck instructions.
• Tighten blade bolts to factory torque and use thread locker if recommended.
• Inspect for cracks, nicks, or bends; replace if damage is found rather than attempting repair.
• Sharpen with a file or bench grinder, maintaining original angle; balance after sharpening.

Why choose OEM John Deere blades instead of aftermarket options?

OEM blades are manufactured to the same tolerances and materials specified by John Deere, ensuring consistent fit and performance across machines. That reduces vibration, improves cut quality, and helps maintain resale value by keeping the machine closer to factory condition.

• Exact fit to spindle and deck geometry for balanced operation.
• Material and heat treatment matched to factory standards for toughness.
• Cross-referenced part numbers simplify ordering the correct replacement.
• Sold as a two-blade set to keep both cutting edges matched for performance.

Who is this for: Owners of John Deere lawn and garden tractors, front mowers and compact tractors with compatible 38" mower decks who want factory-spec replacement blades. If you value blade longevity, balanced cutting performance and the convenience of OEM cross-reference numbers, the John Deere M82408 two-blade set is an appropriate choice. Confirm your machine’s required part number or deck size before purchase to ensure compatibility.
