ZALANA 50" Deck Replacement Mower Blades 3-Pack — 17-13/16" Heat-Treated Steel, 6-Point Star Center

ZALANA 50" deck replacement blades are a three-pack of heat-treated steel mower blades engineered to restore cutting performance for compatible Cub Cadet, MTD and Troy-Bilt 50" deck models.

When a worn or damaged blade reduces cut quality or creates uneven turf, replacing the blade with the correct size and mounting pattern brings your mower back to factory-level trimming. These ZALANA blades fit decks that use a 6-point star 1" center hole and match the original 17-13/16" length, offering a direct-fit replacement for many common part numbers from Cub Cadet, MTD and Troy-Bilt.

Will these blades fit my mower deck and mounting hardware?

These blades are designed to be direct replacements for a long list of OEM part numbers and model families. Check your deck’s blade length and center hole shape; the ZALANA blade measures 17-13/16" and has a 6-point star 1" center hole.

• Blade dimensions: 17-13/16" length, 2-5/16" width, 0.157" thickness.
• Center: 6-point star pattern, 1" diameter hole for OEM fitment.
• Replaces part numbers like 742-04053, 942-04056, 742-04123 and related variants.

Which mower models are compatible with these ZALANA blades?

These blades work with many Cub Cadet, MTD and Troy-Bilt lawn tractors and zero-turn mowers that use a 50" deck configuration. They also cover select Craftsman models listed under similar OEM numbers.

• Cub Cadet examples: RZT50, LTX1050, LT1050, LGT1050 and SLT/SLTX series.
• MTD & Troy-Bilt models: Columbia ZT50, Mustang RZT 50, TB2450 and Mustang XP families.
• Some Craftsman units: ZTL7000 (2012) and PYT9000 (2010) when using the same mounting.

How do these blades perform and what are they made from?

ZALANA blades are manufactured from high-grade steel that is heat-treated to improve edge retention and resistance to wear. The result is a sharper edge that maintains cutting performance longer than untreated alternatives.

• Heat-treated steel construction for improved durability and strength.
• Precisely ground cutting edge for consistent, clean clippings.
• 0.157" thickness provides a balance of rigidity and shock resistance.

What comes in the package and what should I check before installation?

This purchase includes three identical replacement blades, allowing you to service an entire 3-blade 50" deck or keep spares on hand. Before installing, verify the blade length and center hole type, and replace mounting bolts if worn.

• Package: 3 x ZALANA mower blades sized for 50" decks.
• Inspect blade mounting bolts, spindle hardware, and deck for damage before fitting.
• Follow your mower manual for proper blade orientation and torque specifications.

Who is this for: Homeowners and small-property landscapers with 50" mower decks who need a reliable, OEM-compatible replacement are the ideal buyers. If you own a compatible Cub Cadet, MTD, Troy-Bilt or Craftsman model and want a durable, heat-treated blade set that restores a clean cut, this three-pack keeps you mowing with minimal downtime. Avoid purchase if your deck uses a different length, center hole, or mounting pattern; always match the blade dimensions and center pattern to your mower’s specifications before ordering.
