1/2 x 134 Inch Lawn Mower Deck Belt Made with Kevla for 754-04044 954-04044 CUB Cadet MTD RZT RZT22 RZT50 ZT-22 ZT50 ZT-50 ZT-50 17BK2ACP ZT-5000 ZT-L7000

What It Is

This is a 1/2-inch wide, 134-inch long Kevlar-reinforced deck belt designed to drive the cutting blades on select Cub Cadet and MTD zero-turn mowers. It’s a direct replacement for OEM part numbers 754-04044 and 954-04044, commonly used on RZT series models like the RZT22, RZT50, ZT-22, ZT50, ZT-5000, and ZT-L7000.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: This belt fits 50-inch and 22-inch decks (RZT22 uses a 22-inch deck, RZT50/ZT50 use 50-inch decks). Measure your old belt’s length (134 inches) and width (1/2 inch) to confirm.
• Model number: Check your mower’s model tag (usually under the seat or on the frame). It must list one of: RZT22, RZT50, ZT-22, ZT50, ZT-5000, ZT-L7000, or 17BK2ACP. Cub Cadet and MTD branded units with those decks are compatible.
• OEM vs aftermarket: This is a Kevlar aftermarket belt, not OEM. It’s built to match the OEM specs (754-04044 / 954-04044) but may have slightly different stiffness or wear characteristics. Measure your old belt’s length with a tape measure—don’t rely solely on model number, as deck belt routing can vary.

Key Things to Know

• Kevlar construction adds heat and abrasion resistance, lasting longer than standard rubber belts in dusty or heavy-use conditions, but it can be stiffer initially—expect a short break-in period.
• Installation difficulty is moderate: you’ll need to remove the deck or at least access the belt routing diagram (usually on the deck or in the manual). Use a wrench to release the tensioner pulley.
• Common gotcha: The belt must be routed correctly around all pulleys and idlers. A misrouted belt will slip or throw off. Take a photo before removing the old belt.
• One review (5.0/5) suggests it fits as expected—but with only one review, reliability data is thin. Check return policy in case of fitment issues.

Should You Buy It

Buy this belt if you need a direct, Kevlar-reinforced replacement for a worn or broken 134-inch deck belt on a compatible Cub Cadet or MTD zero-turn with a 50-inch or 22-inch deck, and you want better durability than standard rubber at a low price. Skip it if you prefer OEM parts for exact fit or if your mower model isn’t listed—measure first to avoid a return.
