These two KANXAJJY UC22008 lawn mower blades are direct-fit replacements for John Deere M170642 blades, sized for 42-inch decks and designed for durable, rust-resistant cutting performance.

If your John Deere X330, X350, X354, X370, X380 or compatible Z-Trak model needs fresh cutting edges, these blades offer an affordable OEM-equivalent option. Each blade measures 21-2/5" long, 2-1/2" wide and 0.197" thick with a 51/64" center hole, built from high-grade steel with a protective powder coat to resist corrosion and wear during regular lawn use.

How do these blades match my John Deere mower?

They are manufactured to replicate the key dimensions and hole pattern of the original John Deere parts M170642 and UC22008. That means straightforward compatibility for the listed models when the center hole and blade profile match your current setup.

• Replaces OEM numbers M170642 and UC22008
• Center hole: 51/64" to align with factory spindles
• Sized for 42" cutting decks commonly used on the listed tractors and Z-Trak mowers

What materials and finish do these replacement blades use?

KANXAJJY blades are stamped from high-grade steel and finished with a powder-coat layer to slow rust formation and protect the cutting edge between sharpenings. The construction balances toughness with a profile that maintains cutting efficiency and resists chipping under normal lawn conditions.

• High-grade steel core for impact resistance
• Powder-coated finish for corrosion protection
• 0.197" thickness for durability without excessive weight

How easy is it to install these blades on my mower?

Installation is a standard blade swap that any homeowner with basic tools can complete. Always follow safety steps like disconnecting the spark plug and using a wrench to remove the flange nut before replacing the blade.

• Disconnect spark plug before starting
• Lift deck to highest position for safe access
• Remove flange nut, swap blade, then reassemble and test

What should I check before buying these replacements?

Confirm the blade dimensions and the center hole shape on your current blade to ensure a precise fit. Also verify your mower model against the compatibility list so you get the proper part for your deck and spindle arrangement.

• Measure blade length (21-2/5"), width (2-1/2") and thickness (0.197")
• Confirm 51/64" center hole and hole profile match your spindle
• Check your model: X330, X350, X354, X370, X380, Z335E, Z335M, Z345M, Z345R
