GX22151 Toothed Mulching Blades (2-Pack) - Perfect Fit For John Deere 42-Inch Lawn Mowers

Hey there, if you're tired of your John Deere mower not cutting like it used to, these GX22151 toothed mulching blades are exactly what you need. Seriously, they're direct replacements for all those OEM part numbers like GY20850, AM131033, AM137333, and AM141033. They fit a ton of John Deere models too - we're talking D100, D110, D125, S100, S130, S240, LA100, LA105, LA120, E120, E130, Z235... basically if you've got a 42-inch deck John Deere, these should work perfectly. The blades are made from seriously tough high-grade steel that's built to last, and they've got this powder coating that prevents rust and makes cutting way more efficient. Each blade measures 21-3/8 inches long, 2-1/2 inches wide, with a thickness of 0.157 inches, and that center hole is a 7-point star shape. Just double-check your center hole matches before ordering, and you'll be good to go. With two blades in the pack, you'll have a spare ready when you need it. Your grass will thank you for these!
