405143 Mowers Deck Drive Belt 46" fits AYP Craftsman Poulan Husqvarna 46 inch Deck Mower 5324051-43 584453101 YTH22V46 YTH2246TDR YTH22V46XLS YTH23K46 YTA22V46 YTH1k46

What It Is

The 405143 Mowers Deck Drive Belt is a replacement belt for 46-inch cutting decks on select AYP (American Yard Products) Craftsman, Poulan, and Husqvarna lawn tractors. It transfers power from the engine pulley to the deck spindles to spin the blades.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and check your original belt part number. This belt replaces OEM numbers 5324051-43 and 584453101. It fits models including Craftsman YTH22V46, YTH2246TDR, YTH22V46XLS, YTH23K46, YTA22V46, and YTH1k46, plus many AYP-built Poulan and Husqvarna tractors with 46-inch decks. Measure your old belt’s length (typically 1/2-inch wide, roughly 100–105 inches depending on deck design) to verify—though this belt is a standard replacement for these decks, pulley wear or aftermarket pulleys can alter needed length.

Key Things to Know

• Quality: Aftermarket belt, priced below OEM but with good reviews. Expect similar lifespan to OEM if belt path is clean and pulleys are aligned.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least release tension from the idler pulley. Refer to your mower’s deck belt routing diagram (often on the deck or in the manual) to avoid misrouting.
• Common gotchas: Check for worn or frozen idler pulleys before installing—a bad pulley will shred a new belt quickly. Also, ensure belt is seated in all pulley grooves and not twisted.
• Deck removal: On many models, you’ll need to remove the deck from the tractor to access belt routing easily. Kits for deck removal (e.g., lift-assist handles) can save time.

Should You Buy It

If you need a budget-friendly replacement for a worn 46-inch deck belt on a compatible Craftsman, Poulan, or Husqvarna tractor, this belt is a solid choice. It’s well-reviewed and fits common models, but verify your deck size and original part number first, and inspect pulleys before installing.
