UDC Parts 46" Replacement Mower Blades 2-Pack for Cub Cadet 6-Point Star Decks — 46-inch, Heavy-Duty Mulch/Discharge

Two heavy-duty 46-inch, 6-point star replacement mower blades from UDC Parts designed to restore cutting performance on compatible Cub Cadet, Craftsman and Troy-Bilt decks.

These UDC Parts replacement blades replace multiple OEM part numbers for 46" decks that use a 6-point star center hole. Sold as a two-pack, they fit a wide range of Cub Cadet XT1/XT2/LTX/RZT models and many Craftsman and Troy-Bilt 46" machines. Each blade is measured diagonally for overall length and includes the specific hole spacing and air lift geometry needed for proper balance and mulching or discharge performance on compatible decks.

Which mower models and OEM numbers do these blades replace?

These blades are intended for decks that require a 6-point star center hole. They replace a long list of OEM numbers across brands and many model variants, but fitment depends on the exact mower configuration.

• Compatible Cub Cadet OEMs: 942-04290, 942-04290A, 942-04244A, 942-04244, 742-04290 series and related codes.
• Works with Cub Cadet models including XT1, XT2, LTX, RZT and selected LT/LE/EFI variants when the deck uses a 6-point star hole.
• Also fits Craftsman and Troy-Bilt 46" models listed by their part cross-references and model codes in the detailed compatibility notes.

How do the blade dimensions and mounting features affect fit and performance?

The blades have specific physical measurements and hole spacing that determine whether they will mount and perform correctly on your deck. Confirming those dimensions against your existing blades ensures proper fitment.

• Overall diagonal length: 23-1/4"; cutting edge length: 5-7/16".
• Blade width: 2-1/2"; center to outside hole spacing: 2-1/2"; side hole: 21/64".
• Center hole: 6-point star; air lift height: 1-7/64", matching decks designed for this geometry.

What should I check before ordering to make sure these blades will work?

Parts and blade patterns can vary even within the same mower model family. Verify the center-hole shape and the OEM number on your current blade or in the mower parts manual before purchase.

• Confirm your deck uses a 6-point star center hole — these blades will not fit S-shape center hole decks.
• Compare the diagonal blade length and hole measurements listed here to your old blades.
• Match your mower’s full model number and any OEM blade numbers against the compatibility list to avoid mis-fitment.

How will replacing blades with this UDC Parts 2-pack affect cutting results?

Installing fresh, correctly sized blades restores cutting performance and deck balance. Properly matched blades help maintain even clipping, reduce scalping risk when set correctly, and can improve mulching or side-discharge outcomes depending on deck and setup.

• Tighter, cleaner cuts when blades are sharp and balanced to OEM geometry.
• Consistent lift and grass flow thanks to the specified air lift height.
• Reduced vibration and improved deck balance when both blades are replaced as a matched pair.

Who is this for: Gardeners and homeowners who own 46" riding mowers from Cub Cadet, Craftsman or Troy-Bilt and need an exact 6-point star center-hole replacement blade. These UDC Parts blades suit owners who confirmed their deck measurements or OEM blade numbers, want a matched two-blade set to restore balance and cutting quality, and prefer a direct fit alternative to sourcing original OEM parts. Always confirm full mower and deck model numbers before purchase to ensure compatibility.
