54 Inch Cub Cabet 759-3820 742-3013 Mower Blades for Cub Cabet 54 GT 1554 GTX 1054 Troy Bilt RZT 54 Mustang 54 XP Replace 942-3013 Lawn Mower 18 1/2" Blades (3 Pack)

What It Is

This is a 3-pack of 18.5-inch replacement mower blades designed for 54-inch cutting decks on select Cub Cadet, Troy-Bilt, and MTD-brand lawn tractors. They are a direct aftermarket alternative to OEM Cub Cadet blades (part numbers 759-3820, 742-3013, 942-3013) and are intended for standard grass cutting, not mulching or bagging.

Fitment & Compatibility

Before buying, confirm deck width is exactly 54 inches and blade length is 18.5 inches (center hole to tip). These blades fit:

• Cub Cadet: GT 1554, GTX 1054, 54-inch Zero-Turn models (e.g., RZT 54, Z-Force 54)
• Troy-Bilt: Mustang 54 XP, RZT 54
• MTD/Yard-Man models with 54-inch decks using the same spindle pattern

Critical checks:

• Center hole diameter must match your spindle (typically 7/8” or 1” – measure yours)
• Blade offset and thickness should match OEM specs (these are standard .25” thick, flat profile)
• Not compatible with 46-inch or 50-inch decks, or with Cub Cadet XT series (uses different blade shape)

Key Things to Know

• Installation is straightforward if you have a socket set and jack stands. Lift the mower, block the deck, remove the center bolt (left-hand thread on some models), and swap blades. Torque to 70-90 ft-lbs.
• Balance check recommended – aftermarket blades can be slightly off. Use a blade balancer or hang on a nail to verify before installing.
• Sharpening vs. replacement – these are not high-carbon steel; they dull faster than OEM. Replace every 25-30 hours or when you see uneven cut or grass tearing.
• No mulching plugs or bagging baffles – these are standard lift blades. If you need mulching, look for a dedicated mulching blade set.

Should You Buy It

If you have a 54-inch Cub Cadet or Troy-Bilt with the listed models and want a budget-friendly 3-pack for regular mowing, this is a solid value at $37.99. It’s not for heavy-duty or commercial use (expect shorter life than OEM), but for home lawn care with typical grass, it’s a good replacement. Avoid if you need mulching blades or have an XT-series deck.
