John Deere 22 Mower Blade GX23522

What It Is

The John Deere GX23522 is a factory-replacement 22-inch high-lift mower blade designed for cutting grass and mulching light debris on residential lawn tractors. It’s intended for use on John Deere mowers with 22-inch decks that require a dual-blade set.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 22 inches (measure blade length from tip to tip—this blade is 22 inches). It fits John Deere models including the D100, D105, D110, D125, D130, D140, D150, D155, D160, D170, LA105, LA110, LA115, LA120, LA125, LA130, LA135, LA140, LA145, LA150, L100, L105, L107, L108, L110, L111, L118, L120, L130, and X100 series. It also replaces OEM part numbers GX23522, GY20830, GY20831, and AM137277. This is a genuine John Deere blade—aftermarket equivalents exist but may differ in thickness or lift. Check your deck’s spindle bolt size (commonly 5/8-inch) and ensure you have the correct washer and nut. For dual-blade decks, you’ll need two blades.

Key Things to Know

• Quality: Genuine John Deere steel blade with a durable powder-coat finish; holds an edge longer than many aftermarket blades. High-lift design improves bagging and discharge but may reduce engine efficiency in thick grass.
• Installation: Moderate difficulty—requires a socket wrench, torque wrench (recommended 50-60 ft-lbs), and jack stands or blocks to lift the mower safely. Use thread-locker on bolts. Always install with the lift wings pointing up toward the deck.
• Common Gotchas: The blade is 22 inches, not 21 or 20—measure your existing blade. It’s for 22-inch decks only. If your deck uses a different blade pattern (e.g., low-lift or mulching), this high-lift won’t work well for mulching. Check for bent spindles before installing a new blade.

Should You Buy It

Buy this if you own a compatible John Deere lawn tractor with a 22-inch deck and want a reliable, long-lasting factory blade optimized for bagging and discharge. It’s a solid choice for residential use on standard grass heights. Avoid if you need a mulching blade, have a non-John Deere mower, or your deck is a different size.
