CUB CADET 942-05052A Blade 3-Pack RZT Enduro XT1 XT2 Ultima ZT1 ZT2 50" Mowers

What It Is

This is a 3-pack of OEM Cub Cadet 942-05052A blades designed for 50-inch cutting decks on Cub Cadet RZT, Enduro XT1, XT2, and Ultima ZT1/ZT2 zero-turn mowers. These are replacement blades for mulching, bagging, or side-discharge decks.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck—this pack will not fit 46-inch or 54-inch decks. The blades measure 20.5 inches long with a 1-inch diameter center hole and a 0.25-inch thick blade. They are direct OEM replacements for Cub Cadet models: RZT 50, Enduro XT1 LT50, XT2 LX50, Ultima ZT1 50, and ZT2 50. Check your mower’s model number under the seat or on the deck. These are not universal; they only fit Cub Cadet 50-inch decks with the correct spindle pattern.

Key Things to Know

• Quality: OEM Cub Cadet blades—good steel, but some users report they dull faster than aftermarket alternatives like Oregon or Stens. Expect 15-25 hours of cutting before needing sharpening.
• Installation: Easy DIY job; you’ll need a socket wrench and torque wrench (40-50 ft-lbs). The blades are stamped steel, so they’re lightweight but not as durable as forged blades.
• Common gotcha: The blades are sold as a 3-pack, but some decks use two blades (e.g., RZT 50) while others use three (e.g., Ultima ZT1 50). Verify your deck’s blade count—if you have a two-blade deck, you’ll have a spare.
• Price: At ~$70, this is mid-range. Aftermarket 3-packs can be $10-20 cheaper, but OEM ensures fit and warranty compliance.

Should You Buy It

Buy this if you own a Cub Cadet 50-inch zero-turn and want guaranteed OEM fit without measuring or adapting. It’s a solid choice for homeowners who prefer original parts over cheaper aftermarket options. If you’re a heavy user or want longer blade life, consider aftermarket forged blades instead.
