754-06134 RZT Mower 42-inch Deck Belt 1/2" x 117" Made with Kevlar for Cub Cadet Craftsman CMXGZAM501081 490-501-C081 754P06134 490-501-M081

What It Is

This is a Kevlar-reinforced 1/2" x 117" deck belt designed for 42-inch zero-turn mowers, primarily Cub Cadet RZT models and compatible Craftsman units. It drives the mower blades from the engine pulley.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck and requires a 1/2" wide, 117-inch long belt. This belt replaces OEM part numbers 754-06134, 754P06134, 490-501-C081, and 490-501-M081. It fits Cub Cadet RZT 42, RZT 50, and RZT S 42 models, plus Craftsman CMXGZAM501081 and similar zero-turn mowers using a 42" deck. Always measure your old belt’s length (lay it flat, measure end-to-end) and verify the belt routing diagram under your deck or in the manual—routing varies by model. This is an aftermarket replacement, not OEM Cub Cadet, but matches OEM specs.

Key Things to Know

• Kevlar construction improves durability and resists stretching compared to standard rubber belts, but it’s stiffer and may feel tight during installation.
• Installation difficulty is moderate—you’ll need to release tension from the idler pulley (use a wrench or belt tool) and carefully route around all pulleys. A diagram helps; take a photo before removing the old belt.
• Common gotcha: The belt is directional on some models (arrows on the belt indicate rotation direction). Install it correctly to avoid premature wear or slipping.
• Check pulley condition—worn or rusty pulleys will shred any belt quickly. Clean or replace pulleys if needed.

Should You Buy It

Buy this belt if you need a reliable, cost-effective replacement for a 42-inch Cub Cadet or Craftsman zero-turn deck belt. The Kevlar reinforcement gives longer life than standard belts, and the price is fair for the quality. It’s not OEM, but it’s a solid aftermarket match. Skip it if you prefer OEM parts or if your mower uses a different belt length (e.g., 117.5" or 118").
