UDC Parts 54" Mulching Blades 3-Pack, 18-5/8" High-Lift 6-Point Star (942-05056A)

UDC Parts 942-05056A high-lift, 6-point star mulching blades — a 3-pack of heavy-duty replacement blades engineered to fit 54" decks with the 6-point star mounting pattern.

These replacement mower blades are made to match the OEM 942-05056A fitment and cutting profile, delivering the lift and airflow needed for mulching and bagging on compatible Cub Cadet, Troy-Bilt, MTD and Craftsman 54" decks. Because multiple blade center-hole patterns exist for the same mower families, these blades use the 6-point star center mounting only. Review your original blade or mower's parts diagram to confirm compatibility before ordering.

Will these blades fit my mower model?

These blades fit 54" decks that accept the 6-point star center hole pattern corresponding to OEM 942-05056A/742-05056A. They are compatible with many Cub Cadet, Troy-Bilt, Craftsman and MTD models listed by configuration numbers; they will not fit decks using an S-shape or other center patterns.

• Designed for 54" deck sizes with a 6-point star center hole (measure or compare to existing blade).
• Replace OEM part numbers: 942-05056A, 942-05056, 742-05056, 742-05056A.
• Compatible brands: Cub Cadet, MTD, Craftsman, Troy-Bilt when that mower uses the 6-point star mounting.

What are the blade dimensions and mounting details?

Each blade measures 18-5/8" diagonally with a 2-1/2" effective width and a 3" 6-point star center hole. Side hole diameter, outside hole center spacing, air lift, and cutting-edge length match the OEM layout so the blades align with 54" decks designed for this pattern.

• Overall diagonal length: 18-5/8"; cutting edge length: 4-23/32".
• Center hole: 6-point star (3"); side hole: 13/32"; center-to-center outside holes: 3".
• Air lift height: 1-7/32" for improved clippings circulation and mulching action.
• Sold as a 3-pack to service all three spindle shafts on most 54" decks.

How do these blades perform and when should I install them?

These high-lift mulching blades are shaped to lift grass into the deck airflow for finer mulching and cleaner discharge or bagging. Install when edges are worn, bent, or after 2–3 mowing seasons depending on use and terrain; replace in matched sets to maintain balanced cutting and reduce vibration.

• High-lift profile improves clippings lift and mulching consistency.
• Install as a matched set (3 blades) for balanced rotation and reduced vibration.
• Replace when cutting edges are rounded, nicked, or bent to maintain cut quality.
• Follow torque specs and safety procedures when mounting on spindle shafts.

Who is this for: Lawn owners and professional landscapers who operate 54" zero-turn or riding mowers using the 6-point star center-mount pattern and who want a direct-fit, high-lift mulching blade replacement. These blades suit Cub Cadet and related brand owners who confirmed their mower’s configuration matches the listed 6-point star part numbers and who need a three-blade set to restore cutting performance and bagging or mulching efficiency.
