John Deere UC22010 Mower Blades 3-Pack 54" Deck GX225 GX335 GX345 X320 X500 X750 Z535 Z540 Z445

What It Is

The John Deere UC22010 is a 3-pack of high-lift mower blades designed specifically for 54-inch cutting decks on select John Deere lawn tractors, zero-turn mowers, and utility vehicles. These blades are built for residential and light commercial use, providing a clean, consistent cut in grass and light debris.

Fitment & Compatibility

Before buying, confirm your mower has a 54-inch deck (not 48" or 60"). This blade set fits models including: GX225, GX335, GX345, X320, X500, X750, Z535, Z540, and Z445. It also works with select X300, X500, and Z500 series decks. Measure your existing blades – the UC22010 is 21.25 inches long, 2.5 inches wide, with a 1-inch center hole and a 0.375-inch (3/8") thickness. Check your deck’s spindle configuration to ensure a 3-blade setup. These are OEM John Deere blades, not aftermarket, so fitment is guaranteed for listed models.

Key Things to Know

• High-lift design improves grass clipping discharge and bagging performance, but may cause slightly more engine load and wear in thick or wet grass.
• Installation difficulty is low – requires a socket wrench and torque wrench (recommended torque: 70-90 ft-lbs). No special tools needed.
• Common gotcha: Blades are sold as a set of three, but some decks use different blade lengths for outer vs. center positions – verify all three are identical before installing.
• Sharpness out of the box is good but not exceptional; consider sharpening after first use for optimal cut.

Should You Buy It

Buy this if you own a compatible John Deere 54" deck model and want OEM-quality blades that balance durability, cut quality, and easy installation. It’s a solid value for maintaining a clean lawn without overpaying for premium aftermarket options.
