1/2" x 106 3/4" 532405143 inch Lawn Mower Deck V-Belt for AYP 405143, 584453101, Craftsman 7133156, 532405143, 584453101 for Husqvarna YTH20K46, YTH2146, YTH21K46, YTH22V46 Tractors

What It Is

This is a 1/2" wide, 106 3/4" long V-belt that drives the mower deck blades on select Husqvarna, Craftsman, and AYP lawn tractors. It’s an aftermarket replacement for OEM part numbers 532405143, 584453101, and Craftsman 7133156.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits 46-inch cutting decks (common on Husqvarna YTH20K46, YTH2146, YTH21K46, YTH22V46; also Craftsman and AYP models with 46" decks).
• OEM cross-references: Confirmed matches for AYP 405143, 584453101, and Craftsman 7133156. If your mower uses a different OEM belt number, measure your old belt—length and width must match exactly (1/2" wide, 106.75" long).
• Brand/model: Not universal—verify your tractor’s model number against the list. For other brands (e.g., John Deere, MTD), measure first or check your manual.
• Aftermarket note: This is not OEM; quality may vary. Always compare belt construction (cogged vs. notched) and thickness to your original.

Key Things to Know

• Quality: At $13.89, it’s budget-priced. Expect shorter lifespan than OEM in heavy use (e.g., thick grass, frequent mowing). Check reviews for early fraying or slipping.
• Installation: Moderate difficulty. You’ll need to remove the deck or loosen tensioner pulleys. A belt routing diagram is essential—misrouting causes premature wear or blade spin issues.
• Common gotcha: The 106.75" length is critical. Even a 1/4" difference can cause poor tension or belt throw. Measure your old belt (lay flat, no stretch) to confirm.
• Not for self-propelled drive: This is a deck belt only, not for the transmission/drive system.

Should You Buy It

Buy this if you have a compatible 46" Husqvarna/Craftsman/AYP tractor and need a low-cost replacement for light-to-moderate mowing. It’s a solid value for occasional use, but if you mow tough terrain or want longer durability, consider spending more for a premium aftermarket or OEM belt.
