954-04317A 754-0498 Lawn Mower Drive/Deck Belt for Cub Cadet MTD Troy Bilt Ariens 954-04317 754-04317A 754-04317 07211500 RZT-L42 RZT-L46 RZT-L50 RZT-L54 RZT-S42 RZT-S46 RZT-S50 RZT-S54 1/2" x 67"

What It Is

This is a 1/2" x 67" drive/deck belt for zero-turn lawn mowers. It transfers power from the engine pulley to the mower deck blades on Cub Cadet, MTD, Troy-Bilt, and Ariens RZT and RZT-S series mowers.

Fitment & Compatibility

Before buying, measure your old belt—must be exactly 1/2" wide and 67" long. This belt fits Cub Cadet RZT-L42, RZT-L46, RZT-L50, RZT-L54, RZT-S42, RZT-S46, RZT-S50, and RZT-S54 models. Also compatible with select Troy-Bilt, MTD, and Ariens zero-turn mowers with the same deck size range. Cross-references OEM numbers: 954-04317, 754-04317A, 754-04317, 07211500. Not for push mowers or tractors—confirm your deck’s belt routing diagram matches.

Key Things to Know

• Quality: OEM-equivalent construction; reviews note good durability for residential use, but heavy commercial cutting may shorten life.
• Installation: Moderate difficulty—requires removing deck or tensioning pulley. Watch a model-specific video; belt routing is critical and varies by deck size.
• Gotcha: Some users report the 67" length is exact—if your old belt is stretched or a different size, double-check with a tape measure before ordering.
• Torque: Ensure idler pulley and spindles spin freely; a seized pulley will shred this belt quickly.

Should You Buy It

If you own a Cub Cadet or compatible zero-turn in the RZT-L or RZT-S series and need a direct replacement for OEM part 954-04317, this belt is a solid, cost-effective choice. It’s a reliable fit for residential mowing, but commercial operators should consider a heavy-duty alternative for longer life.
