754-05874 Transmission Drive Belt Compatible with Cub Cadet/Craftsman/Troy-Bilt 954P05874, Ultima Series ZT1-42 KH, ZT1-46, ZT1-50 KW, ZT2-54 KW, ZT2-60 KW and ZT3-60 KW

What It Is

This transmission drive belt transfers power from the engine to the hydrostatic transmission on zero-turn mowers. It’s designed for Cub Cadet Ultima ZT and ZT2/ZT3 series models, plus compatible Craftsman and Troy-Bilt units using OEM part 954P05874.

Fitment & Compatibility

Before buying, confirm your mower’s deck size and model series. This belt fits:

• Cub Cadet Ultima ZT1-42 KH, ZT1-46, ZT1-50 KW
• Cub Cadet ZT2-54 KW, ZT2-60 KW, ZT3-60 KW
• Also fits Craftsman and Troy-Bilt models using OEM 954P05874

Measure your old belt: length should be approximately 94.5 inches, width 1/2 inch. This is an aftermarket replacement for OEM Cub Cadet part 754-05874. Verify your machine’s deck size and model number (stamped on frame or under seat) — not all ZT series use the same belt, even with similar deck sizes.

Key Things to Buy

• Quality: Aftermarket belt, not OEM. User reviews are limited (2 ratings, 5.0), so long-term durability is unproven. Expect it to match OEM specs but may wear faster in heavy use.
• Installation difficulty: Moderate — requires removing deck or belt guards, releasing tension from idler pulley, and routing around transmission pulleys. A belt diagram (online or in manual) is helpful.
• Common gotchas: Double-check belt routing before tensioning — reversing direction can cause slipping or premature wear. Ensure tensioner spring is not weak or broken; if it is, replace it to avoid belt failure.
• Price vs OEM: At $18.49, it’s significantly cheaper than Cub Cadet OEM (typically $30–$45). Good for budget replacement if you don’t need OEM warranty.

Should You Buy It

If you own one of the listed Cub Cadet Ultima ZT models and want a budget-friendly replacement for a worn or broken transmission drive belt, this is a solid option. It’s not ideal for heavy commercial use or if you prefer OEM reliability, but for homeowner mowing and occasional use, the price and fitment are right.
