POSEAGLE M145476 Lawn Mower Blades for John Deere 48-inch Deck — Pre-Sharpened, High-Lift

POSEAGLE M145476 lawn mower blades are drop-in replacements for John Deere 48" decks, offering pre-sharpened, high-lift cutting performance and complete bolt kits for quick installation.

These POSEAGLE blades are engineered to match John Deere OEM specifications (replacing UC22009, M145476, M127500, M127673 and Oregon 190-348/330-369) so you get the same fit and cutting geometry for 48-inch decks. Each blade measures approximately 17 inches diagonally, is 2-1/2 inches wide and 0.2 inches thick, with a 13/16" center hole and a 0.92" air lift profile. They arrive pre-sharpened, powder-coated for corrosion resistance, and are supplied with a set of blade bolts and washers sized to common John Deere spindle applications.

Will these blades fit my John Deere 48" mower deck?

Yes — the POSEAGLE M145476 blades are designed to be compatible with many John Deere models that use the 48" deck blade specification. They match the center hole diameter and diagonal blade length used by the original equipment so no modification to the mower deck is required.

• Fits popular models including GX, LT, LX, S, X, Z and GT series listed in the product features.
• Replaces OEM numbers UC22009, M145476, M127500, M127673 and Oregon equivalents.
• 13/16" round center hole aligns with standard John Deere spindle mounting.
• Check your mower manual for blade length and center hole to confirm fit.

How durable and ready-to-use are these replacement blades?

POSEAGLE blades are made from high-strength steel and finished with powder coating to resist rust and abrasion. Each blade is pre-sharpened at the factory and tested for hardness, bending, chipping and balance so they arrive ready to cut without additional sharpening.

• Pre-sharpened edge — no need to sharpen before installation.
• Powder coat finish extends service life by limiting corrosion.
• Passed Rockwell hardness, V-bend, chip and balance tests for reliability.
• High-lift profile (0.92" air lift) improves clippings evacuation and cut quality.

What comes in the box and how easy is installation?

Each set includes the full complement of blades and a selection of blade bolts and washers so you can install them right away. Replacing the blades is a straightforward task: remove the old blades, align the new blade cutting edges in the same rotational direction, and secure them using the supplied hardware and a torque wrench.

• Included hardware: multiple blade bolts (M12x25, M12x30, M12x40) plus washers for proper fitment.
• Installation time: typically minutes per blade for a standard 48" deck.
• Tip: support the cutting deck and stabilize the blade before loosening bolts for safety.
• Sturdy steel construction maintains proper balance once torqued to spec.

How do these blades affect cutting performance on wet or heavy grass?

The high-lift blade profile helps create stronger airflow under the deck, lifting grass higher into the cutting path and moving clippings through the discharge chute more effectively. That airflow and the factory edge combine to improve bagging and side-discharge performance compared with worn or low-lift blades.

• High-lift design reduces clumping by moving clippings away from the deck quickly.
• Sharp factory edge produces cleaner cuts and healthier-looking turf.
• Powder coating helps shed wet debris and resist corrosion after use.
• Maintain rpm and blade sharpness for best wet-grass results.

Who is this for: POSEAGLE M145476 blades are intended for homeowners and landscapers who need a reliable, OEM-compatible replacement for John Deere 48" mower decks. They suit anyone maintaining multiple John Deere models listed in the compatibility notes, and are especially useful for users who want pre-sharpened blades with included mounting hardware for a fast, accurate swap without aftermarket modifications.
