405143 (1/2" x 105.5") 46 inch Mower Deck Belt for Husqvarna YTH22V46 YTH22V42 YTH2146XP YTH2242/ Compatible with Husqvarna 46 inch Deck Belt/Craftsman,Poulan,Dixon,AYP

What It Is

This is a 1/2-inch wide, 105.5-inch long V-belt designed for 46-inch mower decks on select Husqvarna, Craftsman, Poulan, Dixon, and AYP lawn tractors. It transfers power from the engine pulley to the deck spindles, driving the blades.

Fitment & Compatibility

Check your deck size—this belt is only for 46-inch decks, not 42 or 54-inch. Verify your model number against the list: Husqvarna YTH22V46, YTH22V42, YTH2146XP, YTH2242, plus many Craftsman, Poulan, Dixon, and AYP models with 46-inch decks. Measure your old belt: if it’s 105.5 inches long and 1/2 inch wide, it’s a match. OEM part numbers include Husqvarna 532405143, 405143, and Craftsman 532405143. If your mower uses a 3/8-inch or 5/8-inch wide belt, this won’t work.

Key Things to Buy

• Quality variance: At $14.99, this is a budget belt. Some users report shorter lifespan (1-2 seasons) compared to OEM belts. Inspect for fraying after heavy use.
• Installation is moderate: You’ll need to remove the deck or at least the belt guards. Route exactly as the old belt—take a photo before removal.
• Common gotcha: The 105.5-inch length is critical. A belt that’s too long will slip; too short won’t fit. Measure your old belt or confirm deck model.
• No tensioner adjustment: Most 46-inch decks use a spring-loaded tensioner—no manual adjustment needed, but ensure the spring is not worn.

Should You Buy It

Buy this if you need a quick, affordable replacement for a 46-inch Husqvarna or Craftsman deck and don’t mind replacing it every year or two. Skip it if you want a longer-lasting, heavy-duty belt for commercial use or frequent mowing—spend more on an OEM or Gates belt.
