What It Is

This is a replacement deck belt for 46-inch cutting decks on Husqvarna, Craftsman, and Poulan Pro lawn tractors. It drives the mower blades and is built with aramid cord for increased durability over standard belts.

Fitment & Compatibility

Before buying, confirm your deck is 46 inches and your belt measures exactly 1/2" x 105.75". This belt replaces OEM part numbers 405143, 584453101, and 532405143. It fits models like Husqvarna YTH22V46, YTH20K46, YTH21K46, YTA22V46, YTH2246, YT46LS, YTH18K46, and Craftsman equivalents. Check your owner’s manual or the old belt part number—do not rely on model name alone. This is an aftermarket belt, not OEM.

Key Things to Know

• Aramid cord construction resists stretching and snapping longer than standard rubber belts, especially under heavy grass or frequent use.
• Installation is moderate difficulty—you’ll need to remove the deck or at least the belt shield. Watch a model-specific video if you’re unsure.
• Common gotcha: The belt must route correctly around all pulleys and tensioners. A wrong path causes slipping or premature wear. Take a photo before removing the old belt.
• Measure twice: Even a 1/4-inch length difference can cause poor engagement or blade speed issues. Verify your old belt’s length before ordering.

Should You Buy It

If you need a reliable, longer-lasting belt for a 46-inch Husqvarna, Craftsman, or Poulan Pro tractor and you’re comfortable with a moderate DIY install, this is a solid upgrade over basic belts. The aramid cord and high rating make it a safe bet—just confirm your model and deck size first.
