954-04329A Deck Belt 5/8" x 148 1/4" Fits for 954-04329 754-04329 754-04329A 490-501-C067, for MTD/Cub Cadet 54" Deck RZT- L54 S54 LX54 ZT1-54 ZT-S54

What It Is

This is a 5/8-inch wide by 148 1/4-inch long deck belt designed for 54-inch cutting decks on select MTD/Cub Cadet zero-turn mowers, including RZT, S, LX, ZT1, and ZT-S series models. It drives the blades via the deck spindle system.

Fitment & Compatibility

• Deck size: 54-inch deck only. Measure your old belt to confirm length (148.25 inches) and width (5/8 inch). A 1/2-inch belt will not work.
• Models: Fits Cub Cadet RZT-L54, S54, LX54, ZT1-54, ZT-S54, and some MTD variants with the same deck. Check your mower’s model number against the OEM part numbers: 954-04329, 754-04329, 754-04329A, 490-501-C067.
• OEM vs aftermarket: This is an OEM-equivalent belt (not genuine Cub Cadet), but matches original specs. Verify your mower uses a single-belt deck system (not a two-belt setup) before ordering.
• Cross-reference: Also replaces 754P04329, 954P04329, and 490-501-C067. If your manual lists one of those, it’s a direct swap.

Key Things to Know

• Quality: Users report reliable performance for residential use, but some note it may stretch slightly faster than OEM. Expect 1-2 seasons of normal mowing.
• Installation difficulty: Moderate. Requires routing around deck pulleys and a tensioner. Have a wrench and belt removal tool handy; a diagram helps.
• Gotcha: Check pulley alignment before installing—worn pulleys can cause premature belt wear. Also ensure belt is not twisted when seated.
• Common issue: If your deck vibrates after replacement, re-check belt tension and pulley engagement; overtightening can damage bearings.

Should You Buy It

This belt is a solid value for homeowners with a 54-inch Cub Cadet ZT mower needing a direct replacement. It fits correctly, costs less than OEM, and performs well for regular cutting. If you mow commercially or need maximum durability, spring for the genuine Cub Cadet belt instead.
