Aeagle High-Lift Mower Blades for John Deere 48" Deck — M145476 Replacement, Heat-Treated Steel, Resharpenable (Black)

Aeagle M145476 high-lift 48" mower blades are heavy-duty replacement blades engineered to restore cutting performance on compatible John Deere 48-inch decks for both discharge and bagging.

If your mower is leaving uneven clippings, struggling with bagging, or simply needs a fresh, durable blade set, these Aeagle high-lift blades match the specs of John Deere part numbers such as M145476, M127500, M127673, AM141907 and AM148663. Built to the same center-hole profile and dimensions as OEM units, they are designed to fit a wide range of lawn tractors and zero-turn mowers with a 48" deck. The blades combine a pronounced lift curve for superior airflow with a resharpenable steel edge and a protective safety coating to limit corrosion during initial use.

Which John Deere models will these Aeagle blades fit?

These blades are made for 48" decks and match the center-hole circle shape of the listed John Deere parts. They fit many X300, X500, X700, X900, Z300, Z500, GX and LT family mowers, plus several compact tractor decks.

• Compatible with John Deere models: X300 series, X500/X700/X900 series, Z300/Z500 zero-turns, GX and LT tractors listed in the product specs.

• Deck size: 48" — verify your deck measurement and center hole shape before installing.

How do these high-lift blades improve cutting and bagging?

The pronounced upward camber of the Aeagle high-lift profile creates stronger suction beneath the deck so grass stands up for a cleaner cut and more consistent transport into the chute or bag. That makes them particularly effective for tall, dense, or slightly wet grass where airflow matters.

• High-lift curve increases airflow for better bag filling and discharge.
• Sharp resharpenable edges maintain cutting quality over multiple seasons.
• Dual-purpose design: effective for both side-discharge and bagging configurations.

What are the blade dimensions and material details?

Each blade measures 17 1/4" long, 2 1/2" wide, and 0.197" thick with a circular center hole to match common John Deere deck fittings. The construction uses heat-treated steel for strength and edge retention, and a safety paint coating protects the cutting edge during shipping and initial use.

• Dimensions: 17.25" length, 2.5" width, 0.197" thickness.
• Center hole: circular profile — ensure this matches your spindle adapter.
• Finish: safety paint on cutting edge that will wear off and is safe to resharpen.

How should I install and maintain these Aeagle blades?

Installation follows the same procedure as OEM blades: disconnect spark, remove old blade with the correct torque, and reinstall the new blade with proper rotor orientation. Maintain by checking balance, sharpening when dull, and replacing blades if bent or cracked.

• Safety first: disconnect battery or spark plug before work.
• Check blade orientation to preserve lift profile and airflow direction.
• Resharpen when edges become dull; replace if compromised by impact damage.
