What It Is

This is a 1/2-inch wide, 117-inch long replacement deck belt for 42-inch mower decks. It drives the blades on specific zero-turn (RZT) and lawn tractor models from Cub Cadet, Craftsman, and Hustler.

Fitment & Compatibility

• Measure first: Confirm your existing belt is 1/2" wide and exactly 117" long. Even 1/4" off can cause slipping or poor blade engagement.
• Deck size: Designed for 42-inch cutting decks only. Do not use on 46" or 54" decks.
• OEM reference: Replaces Cub Cadet 754-06134, 754P06134, 490-501-C081, 490-501-M081. Also fits Hustler 771824.
• Common models: Cub Cadet RZT 42, RZT L42, RZT S42; Craftsman ZT 7000; CMXGZAM501081. Verify your model number in the owner’s manual.
• Aftermarket note: This is an aftermarket belt. It may be slightly stiffer than OEM but performs identically if measurements match.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to release the idler pulley tension and route the belt around all three spindles and pulleys. A diagram helps—snap a photo before removal.
• Belt quality: Polyester-cord construction. Rated for typical residential use. Not for heavy commercial or daily rental fleets.
• Break-in period: Expect slight stretch after the first 30 minutes. Recheck tension and adjust if needed.
• Common gotcha: If your mower vibrates or throws the belt after replacement, check that the belt is fully seated in all pulley grooves and the idler arm moves freely.

Should You Buy It

Yes, if you have a 42-inch Cub Cadet or Craftsman RZT mower and need a reliable, budget-friendly replacement for a worn or broken deck belt. It’s not for commercial duty, but for home use it’s a solid value at this price.
