What It Is

This is a 134-inch replacement deck belt designed for 50-inch cutting decks on select MTD, Cub Cadet, Toro, Craftsman, Ariens, and Woods lawn tractors. It drives the mower blades from the engine pulley, making it essential for reliable grass cutting.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch deck and requires a 134-inch belt. This belt matches OEM part numbers 754-04077, 954-04077, 112-0332, Woods 18879/18879RP, and Ariens 07234600/07200712. It fits models like Cub Cadet LT1050, XT1, LT50, SLT1550; Toro LT1050; Craftsman T260; and Ariens GT2100, GT2200, LX500. Measure your old belt length (lay it flat, measure end-to-end) and check your deck’s belt routing diagram—some models route the belt around idler pulleys differently. This is an aftermarket belt, not OEM, so verify width (typically 1/2 inch) and cross-section (A-section or Kevlar-reinforced).

Key Things to Know

• Quality: Most users report good durability for residential use, but it may not last as long as OEM belts under heavy commercial or wet-cutting conditions.
• Installation: Moderate difficulty—requires removing the deck or accessing pulleys. Use a belt tensioner tool or socket to release tension. Disconnect the spark plug first.
• Common gotcha: The belt can be tight to install; do not force it over sharp pulley edges. If it slips or squeals after installation, recheck routing and tension.
• Storage: Store in a cool, dry place to prevent cracking. Replace if you see fraying, glazing, or cracks.

Should You Buy It

If you need a budget-friendly, solid replacement for a 50-inch deck belt on a common MTD/Cub Cadet or compatible tractor, this is a good buy. It’s not built for heavy-duty commercial use, but for residential mowing it offers reliable performance at a lower price than OEM. Just double-check your deck size and belt routing first.
