JSXDNWYJ High-Lift Replacement Mower Blades for John Deere 48" Deck — 3-Pack, 17-1/4" x 2-1/2", 5/8" Hole

These are a set of three high-lift replacement mower blades engineered to fit 48-inch decks on many John Dee re and similar models, replacing OEM M145476, M127673, M127500, and UC22009.

When a dull or damaged blade is slowing your cut, replacing blades with the correct length, hole size and lift profile restores cutting performance and bagging efficiency. These JSXDNWYJ blades are specified for 17-1/4" length, 2-1/2" width, 0.197" thickness and a 5/8" center hole—dimensions matched to a long list of John Dee re residential and commercial mower series for a direct-fit swap on 48" decks.

Which mowers will these blades work with?

These blades are designed to be compatible with many John Dee re series and other machines that accept the same OEM part numbers. They fit a wide range of X, GX, LT, LX, S, Z and EZtrak models that use 48" decks and the listed OEM replacement numbers.

• Replaces OEM numbers: M145476, M127673, M127500, UC22009
• Common fits include: X300, X320, X350, X570, X580 series and X700 series
• Also fits GX255/GX325, LT180/LT190, LX280/LX289, S240, ZTrak and select Z-series models

How do these blades affect cutting and bagging performance?

High-lift blade geometry increases air flow under the deck, improving grass lift and producing a cleaner cut edge and better bag fill. Better suction helps pull clippings into the bagging system while also promoting an even discharge for side- or mulch-capable decks.

• High-lift profile for stronger vacuum and improved bagging
• Precise length and hole size for balanced rotation and reduced vibration
• Thicker steel (0.197") for longer edge life and resistance to bending

What should I check before installing these replacement blades?

Confirm your mower’s deck size is 48" and that the factory parts list includes one of the OEM numbers this set replaces. Also inspect spindle hardware and ensure blade mounting hardware matches the 5/8" center hole; replace worn bolts or adapters before tightening new blades.

• Verify deck size is 48" and OEM numbers match
• Measure center hole and use correct mounting hardware
• Balance and tighten blades to manufacturer torque specs after installation

How durable are these JSXDNWYJ replacement blades?

The blades are manufactured to meet the indicated thickness and dimensions for reliable service life under normal lawn care conditions. While they resist everyday knocks and maintain edge life longer than thinner aftermarket options, replacing blades after heavy impact or bent condition is still recommended to avoid mower damage.

• Constructed to OEM-matching thickness for durability
• Triple-pack allows rotating spares and staggered replacement
• After-sales support available for fit or quality questions

Who is this for? Homeowners and landscaping professionals who operate John Dee re or compatible tractors with a 48" deck and need a high-lift blade for improved bagging and cleaner cuts will find this 3-pack useful. It’s aimed at anyone looking to restore cutting performance quickly with a blade that matches OEM dimensions and lift characteristics without buying dealership parts.
