What It Is

This is a three-pack of medium-lift mower blades designed for 48-inch John Deere decks. They replace OEM part numbers M145476, M127673, and M127500, and are intended for residential mowing on standard turf, not heavy mulching or bagging.

Fitment & Compatibility

Deck size is critical – these blades only fit 48-inch John Deere decks, not 42-inch or 54-inch. Check your deck’s stamped model number before ordering. Compatible with these tractor models: 325, 335, 345, 355D, GX255, GX325, GX335, GX345, GX355, LT180, LT190, LX280, LX289, S240, SST18, X300, X304.
Measurements – Blade length is 19.25 inches, center hole is 1 inch diameter, with a 7-point star drive. Confirm your deck uses this star pattern, not a round hole.
OEM cross-reference – Direct replacement for John Deere parts M145476, M127673, M127500.

Key Things to Know

• Medium lift – Good for level cutting and light grass. Not ideal for thick, wet, or tall grass; may leave clumps.
• Installation – Use a torque wrench to 70-90 ft-lbs. Star pattern can strip if overtightened or if bolts are worn. Replace bolts if rusty.
• Quality – At this price point, expect thinner steel than OEM. May dull faster in sandy or rocky soil. Sharpen before first use if edges feel rough.
• Balance – Aftermarket blades sometimes come slightly unbalanced. Check with a blade balancer before installing to prevent vibration and spindle wear.

Should You Buy It

Buy this if you need a budget-friendly 3-pack for a 48-inch John Deere with a star drive and do light residential mowing on clean, dry lawns. Skip it if you mow heavy, wet grass, need mulch or bagging performance, or want OEM durability for commercial use.
