ACEBRI Mower Blades 50 inch for Troy Bilt for Cub Cadet 942-05052A 742-05052 for Cub Cadet ZT1 ZT2 Ultima RZT XT1 LT50 XT2 L50 LX50 S50 GT50 Z550 T260, 3Pak

What It Is

This 3-pack of ACEBRI mower blades is a replacement set designed for 50-inch cutting decks on select Troy-Bilt and Cub Cadet lawn tractors and zero-turn mowers. They are intended for residential use, replacing OEM part numbers 942-05052A and 742-05052.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 50 inches (measured blade tip to blade tip). These blades fit specific Cub Cadet models: ZT1, ZT2, Ultima, RZT, XT1, XT2, LT50, L50, LX50, S50, GT50, Z550, and T260. Also compatible with select Troy-Bilt models using the same OEM part number. Do not assume fitment based on brand alone—cross-reference your mower’s manual or current blade’s part number. Measure blade length (likely 16.5 inches), center hole diameter (usually 5/8-inch or 7/16-inch), and thickness (0.20–0.25 inches) to confirm. Aftermarket blades may vary slightly from OEM, so check that the offset and lift profile match your deck’s design.

Key Things to Know

• Quality & balance: Most users report these blades are well-balanced and cut evenly, but inspect each blade for warping or burrs before installation—common with budget aftermarket sets.
• Installation difficulty: Easy swap with basic tools (socket wrench, jack or ramps to lift the mower). Always disconnect the spark plug and block blades before removing.
• Common gotchas: These blades may require re-sharpening sooner than OEM steel; consider buying a spare set. Also, the coating can wear off quickly if you mow wet grass or sandy soil.
• Deck compatibility: For zero-turn models (ZT1, ZT2, Ultima), ensure the blade spindle pattern matches—some Cub Cadet ZT decks use a slightly different bolt pattern.

Should You Buy It

This is a solid budget-friendly option if you need a quick replacement for a 50-inch residential Cub Cadet or Troy-Bilt mower and don’t mind slightly shorter lifespan than OEM blades. It’s best for homeowners mowing standard lawns (not heavy-duty or commercial use) who want a functional, low-cost set that’s easy to install and balance. Avoid if you need premium steel for tough conditions or exact OEM fitment.
