What It Is

This is a set of three medium-lift replacement blades for 54-inch cutting decks, designed for residential lawn tractors and zero-turn mowers from Craftsman, Cub Cadet, and Troy-Bilt. The medium-lift profile balances bagging performance with clean side-discharge, making it a solid all-around choice for regular mowing.

Fitment & Compatibility

• Deck size: only fits 54-inch decks. Measure your deck width before buying.
• OEM cross-reference: replaces 742-05056, 742-05056a, and 942-05056. Aftermarket equivalent to Cub Cadet/Craftsman OEM parts.
• Fitment check: fits Craftsman T310, T3200, T8400; Cub Cadet XT1-ST54KH, XT2-GX54; Troy-Bilt Mustang 54 XP and Super Bronco. Not compatible with 42-inch or 46-inch decks.
• Physical specs: 3 blades per pack, each ~18.5 inches long with a 1-inch center hole and 7-point star drive. Measure your current blade’s length, hole size, and drive pattern to confirm.

Key Things to Know

• Medium lift means good for most grass types and conditions; not ideal for heavy wet grass or fine mulching.
• Installation difficulty: easy with a socket wrench and blade removal tool. Always disconnect the spark plug and block the blade before loosening.
• Torque to spec: tighten center bolt to 70–90 ft-lbs. Overtightening can strip the spindle; undertightening can cause blade wobble.
• Sharpening: these are heat-treated steel; you can sharpen them 2–3 times before replacement. Check for bends or cracks each season.

Should You Buy It

If you own a 54-inch deck Craftsman, Cub Cadet, or Troy-Bilt tractor and need a reliable, budget-friendly replacement set for general mowing, this is a solid choice. It’s not for heavy-duty commercial use or fine mulching, but for weekly residential cuts, the medium lift gives good performance and the price per blade is hard to beat.
