What It Is

These ACEBRI mower blades are a 3-pack of 54-inch deck blades designed specifically for MTD and Cub Cadet zero-turn mowers. They are aftermarket replacements for OEM part numbers 942-0677, 942-0677-A, 942-0677-B, and 942-0677-X, intended for residential and light commercial cutting.

Fitment & Compatibility

Before buying, confirm these four things:

• Deck size: These blades fit only 54-inch cutting decks. Measure your deck width if unsure.
• Mounting pattern: They use a 6-point star center hole. Check your spindle’s star pattern—this won’t fit round or 5-point hubs.
• Model compatibility: Works with Cub Cadet RZT-S54, RZT-L54, RZT54, GT1054, GT1554, LGT1054, T310, and similar MTD-built models. Verify your specific model number on the mower’s data tag.
• Dimensions: Each blade is approximately 18 inches long, 2.5 inches wide, with a 0.25-inch thickness and a 1-inch center hole diameter. Measure your old blade to match.

Key Things to Know

• Installation difficulty: Easy—no special tools beyond a socket wrench. Torque blade bolts to 70–90 ft-lbs. Use thread-locker if bolts are reused.
• Quality: These are aftermarket blades, not OEM. Expect adequate durability for typical residential use, but they may dull faster than genuine Cub Cadet blades on rough terrain or heavy grass.
• Common gotchas: The 6-point star must align perfectly with your spindle; any wear on the spindle can cause wobble. Also, these blades are sold as a 3-pack—if you only need one, you’ll have spares.
• Balance check: Always balance new blades before mounting to avoid vibration and spindle damage. Use a simple blade balancer.

Should You Buy It

If you own a compatible 54-inch Cub Cadet or MTD zero-turn and want a budget-friendly 3-pack for regular residential mowing, these are a solid value. Skip them if you need OEM-grade longevity for commercial use or if your spindle has a different mounting pattern.
