405143 Repacement Belt/Kevlar Cord / 1/2" x105 3/4" - Compatible with 46 inch Deck AYP/Poulan/Husqvarna/Craftsman 532405143/21546607/584453101

What It Is

This is a replacement drive belt for 46-inch cutting decks on select AYP, Poulan, Husqvarna, and Craftsman lawn tractors. The Kevlar cord construction is designed for higher strength and heat resistance compared to standard rubber belts.

Fitment & Compatibility

Critical checks before purchase:

• Deck size: Only for 46-inch decks. Verify your deck width (measure blade tip to blade tip).
• OEM numbers: Cross-references to 532405143, 21546607, 584453101. Check your old belt for these numbers.
• Dimensions: 1/2" wide x 105 3/4" long. Measure your old belt’s length (lay flat, measure end to end). A 1/4” difference can cause slippage or poor engagement.
• Brand fit: Compatible with AYP/Husqvarna/Poulan/Craftsman tractors using a 46" deck (e.g., Craftsman GT5000, Poulan Pro 46, Husqvarna YTH24V46). Not for 42" or 54" decks.
• Belt routing: Confirm your deck uses a single-belt system (not a two-belt setup). Some models have different pulley configurations.

Key Things to Know

• Kevlar cord = longer life: Handles higher tension and heat better than standard rubber, but may be slightly stiffer during installation.
• Installation difficulty: Moderate. Requires removing the deck (or at least the belt guard and tensioner). Have a socket set and a belt installation tool (or a long screwdriver) handy.
• Common gotcha: The belt may appear too tight or too loose if your tensioner spring is worn or if pulleys are misaligned. Replace the belt with the tensioner released.
• No OEM branding: This is an aftermarket belt. It fits the specs but may not have the exact OEM rubber compound. Check for fraying or cracking after the first few hours of use.

Should You Buy It

Buy this if you have a 46-inch deck tractor from AYP, Poulan, Husqvarna, or Craftsman and need a cost-effective replacement that matches OEM specs. It’s a solid upgrade over standard rubber belts for heat resistance, but skip it if you want an exact OEM-branded belt or if your deck has unusual pulley spacing (measure twice).
