What It Is

This is a replacement deck drive belt (5/8" x 85.5") for Husqvarna, Craftsman, AYP, and Poulan lawn tractors with 46" or 50" cutting decks. It transfers power from the engine pulley to the mower blades, making it essential for cutting performance.

Fitment & Compatibility

Before buying, confirm your deck size (46" or 50") and measure your old belt length—this belt is 85.5 inches long. It fits models like Husqvarna GTH2350, GT200, YTH180, YTH2046, GTH225, GTVH200, YTH1746, YTHK180, and Poulan PP20H46A. Also compatible with Craftsman and AYP tractors using OEM part 532148763 or 531300769. Check your owner’s manual or deck underside for model number; aftermarket belts may vary slightly in tension, so verify pulley alignment.

Key Things to Know

• Material: Aramid (Kevlar-like) cord provides higher tensile strength and heat resistance than standard rubber—good for heavy mowing.
• Installation: Moderate difficulty; you’ll need to remove the deck or access the belt routing diagram. Release tension by loosening the idler pulley.
• Common Gotcha: Ensure the belt is routed correctly around all pulleys and tensioner—misrouting causes slipping or premature wear.
• Cross-Reference: Double-check that your old belt matches 5/8" width and 85.5" length; even minor differences can cause poor engagement or deck vibration.

Should You Buy It

If you need an affordable, durable replacement for a 46" or 50" deck on a Husqvarna, Craftsman, AYP, or Poulan tractor, this belt is a solid choice. It’s a good value for DIYers with moderate mechanical skills, but verify your model and deck size first to avoid fitment issues.
