What It Is

This is a 46-inch deck drive belt (OEM part #405143 / 532405143) that transfers power from the engine pulley to the mower deck spindles. It’s designed for AYP (American Yard Products) built riding mowers under brands like Craftsman, Poulan, and Husqvarna with a 46-inch cutting deck.

Fitment & Compatibility

Check these before buying:

• Deck size: Must be exactly 46 inches (measure deck housing width, not blade length).
• Model numbers: Confirmed fit for Craftsman YTH22V46, YTH2246TDR, YTH22V46XLS, YTH23K46, YTA22V46, YTH1K46, and similar AYP-built 46-inch decks.
• OEM cross-reference: Replaces OEM #532405143, 584453101, and 5324051-43.
• Belt dimensions: Approx. 1/2 inch wide x 96.5 inches effective length. If your original belt is longer/shorter or wider/narrower, this won’t work.
• Brand note: Fits Craftsman, Poulan, Husqvarna, and other AYP-sourced models—not for John Deere, MTD, or Toro 46-inch decks.

Key Things to Know

• Quality: Aftermarket belt at a budget price. Expect 1-2 seasons of residential use; not for heavy commercial mowing.
• Installation: Moderate difficulty—requires removing deck or belt guides. Have a diagram of belt routing handy (common gotcha: routing it wrong causes slipping).
• Common gotcha: Check your deck’s spindle pulleys for wear or wobble before installing a new belt. Bad pulleys will shred a new belt quickly.
• Tension: Some users report needing to adjust the idler pulley tension after installation to prevent squealing or slipping.

Should You Buy It

If you need a quick, affordable replacement for a worn belt on a standard residential 46-inch AYP riding mower (Craftsman, Poulan, Husqvarna), this is a solid budget option. It’s not built for heavy-duty or commercial use, but for typical lawn cutting it’ll get the job done. Skip if you want OEM durability or have a non-AYP deck.
