405143 Lawn Mower Deck Belt for 46" Deck Husqvarna Craftsman 532405143 YTA 22V46 YTH22V46 YTH20K46 2246LS 2346XLS, Ariens 21546607 AYP 584453101 7133156 | Aramid Cord | 1/2 x 106 inch

What It Is

This is a replacement deck drive belt (1/2 inch wide, 106 inches long) for 46-inch cutting decks on Husqvarna, Craftsman, Ariens, and AYP lawn tractors. It transfers power from the engine pulley to the blade spindles, enabling the mower to cut grass.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: Must be exactly 46 inches (measured blade tip to tip).
• Model numbers: Confirmed to fit Husqvarna YTA 22V46, YTH22V46, YTH20K46; Craftsman 2246LS, 2346XLS; and Ariens models using OEM part 21546607.
• OEM cross-references: Replaces Husqvarna/Craftsman 532405143, AYP 584453101, and Ariens 7133156.
• Physical check: Measure your old belt’s length (106 inches) and width (1/2 inch). If yours is worn, frayed, or stretched, this is the direct replacement. Avoid assuming fit based on brand alone—check the model plate under the seat or on the deck.

Key Things to Know

• Aramid cord construction: This belt is stronger and more heat-resistant than standard rubber belts, lasting longer under heavy use or dusty conditions.
• Installation difficulty: Moderate. You’ll need to remove the deck or use a belt routing diagram (check your manual or online). No special tools required, but a socket set and a spring puller help.
• Common gotcha: If your old belt was 105 or 107 inches, this 106-inch belt may not fit—measure twice.
• No universal fit: It does not work on 42-inch or 54-inch decks, or on zero-turn mowers. Double-check your deck’s model number.

Should You Buy It

Yes, if you need a durable, direct replacement for a 46-inch deck belt on a Husqvarna, Craftsman, or Ariens tractor listed above. The aramid cord gives it better longevity than budget belts, and the price is fair for the quality. Avoid if your deck size or model isn’t confirmed compatible.
