8TEN Mower Blades for John Deere X380 X390 Z425 — 18.875in High-Lift 3-Pack, Hardened Steel

8TEN LawnRAZOR High-Lift replacement blade is a three-pack of heavy-duty 18.875-inch mower blades engineered to restore cutting performance on many John Deere lawn and garden tractors and zero-turn mowers.

If your mower is leaving uneven clippings, scalloped edges, or reduced bagging power, fresh high-lift blades can make a noticeable difference. These 8TEN LawnRAZOR blades match the key dimensions and mounting hole pattern of common John Deere OEM parts (M152726, UC22010), so they fit numerous GX, LX, X and Z series models. They are designed with a rolled, high-lift profile to create stronger airflow for better clippings lift and collection while maintaining a balance between durability and sharpness.

Will these blades fit my John Deere mower?

These blades are sized and drilled to be direct-fit replacements where OEM M152726 or UC22010 are specified. Check your mower’s current blade measurements and hole diameter to confirm compatibility before ordering.

• Blade length: 18 7/8 inch (18.875") for edge-to-edge fit
• Width: 2 5/8 inch (2.638") and thickness: 0.197 inch
• Center hole circle diameter: 13/16 inch (0.795") to match spindle hardware
• Compatible models include many John Deere GX, LX, X and Z series machines

How does the high-lift profile affect performance?

The high-lift rolled design increases airflow under the deck, which helps lift grass blades upright before cutting and improves vacuum for side-discharge and bagging systems. That means cleaner cuts and more efficient grass collection on lighter and medium-density turf.

• Stronger suction for improved bagging and chute flow
• Cleaner, more uniform clippings for a manicured appearance
• Works well on regular lawn conditions and seasonal growth

Are these blades durable and easy to replace?

8TEN LawnRAZOR blades are manufactured from hardened steel with a rolled lift edge to resist deformation during routine cutting. Installation is straightforward: remove the worn blade from the spindle, align the new blade’s center hole, and torque the spindle bolt to the mower manufacturer’s specification.

• Hardened steel construction for extended edge life
• Rolled-lift profile reduces edge chipping and wear
• Sold in a convenient three-pack to service multiple spindles or keep a spare on hand

What should I check before buying and installing these blades?

Before purchase, verify that your mower’s OEM part number or blade geometry matches the 8TEN LawnRAZOR dimensions. Always follow safety guidelines when changing blades: disconnect spark plug, stabilize the deck, and use proper tools and torque values for spindle hardware.

• Confirm OEM match: John Deere M152726 or UC22010 compatibility
• Measure existing blade length, width, thickness, and center hole to double-check fit
• Follow manufacturer torque specs and safety steps during installation

Who is this for? If you own a compatible John Deere GX, LX, X or Z series tractor or zero-turn mower and need to restore cutting performance, the 8TEN LawnRAZOR high-lift blade 3-pack is a practical replacement option. It suits homeowners and landscapers seeking a direct-fit, cost-effective blade that improves bagging and produces cleaner cuts without custom modifications. Keep one set per mower for routine seasonal blade changes or to replace dull or damaged blades quickly.
