What It Is

This is a set of three 54-inch toothed blades designed for 3-in-1 mulching, bagging, and side discharge on zero-turn and lawn tractors. It’s made for Cub Cadet RZT-54, RZT-S54, GT1054, GT1554, LGT1054, Troy-Bilt Mustang 54 XP, and Craftsman Z6600 models.

Fitment & Compatibility

• Deck size: Only fits 54-inch cutting decks. Measure your deck width before ordering.
• Mounting pattern: Uses a 6-point star center hole. Check your spindle’s star pattern—some older decks use a 5-point star or round hole.
• OEM cross-reference: Replaces Cub Cadet 942-0677-X, 942-0677, and 742-0677. Aftermarket, not OEM.
• Blade dimensions: 23.25 inches long, 2.75 inches wide, 0.25 inches thick. Confirm your current blade length matches.
• Model verification: The listed models are correct, but always double-check your machine’s serial number or deck model sticker under the seat.

Key Things to Know

• Mulching performance: The toothed design lifts clippings for finer mulching, but it may leave clumps in wet grass—sharpen before first use.
• Installation: Straightforward if you have a torque wrench. Use Loctite on spindle bolts and torque to 70–90 ft-lbs. Star pattern must align perfectly; don’t force it.
• Balance: Aftermarket blades often need balancing out of the box. Use a blade balancer or take them to a shop to avoid vibration.
• Durability: Thicker steel than OEM, but the toothed edge dulls faster on sandy soil. Expect 1–2 seasons with normal use.

Should You Buy It

Buy this if you have one of the listed 54-inch decks, want a budget-friendly 3-in-1 set, and are comfortable balancing and torquing blades yourself. Skip it if you need OEM fit guarantee or if your deck uses a different center hole pattern.
