405143 Deck Drive Belt(1/2" x 106") for 46" AYP Husqvarna Poulan Craftsman 2246LS 2346XLS YTH22V46 YTH20K46 YTH2146XP 532405143 21546607 584453101

What It Is

This is a 1/2" x 106" deck drive belt designed to transfer power from the engine pulley to the mower deck spindles on 46" cutting decks. It fits select AYP/Husqvarna/Poulan/Craftsman lawn tractors from the mid-2000s to present.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch stamped steel deck and uses a 1/2" wide, 106" long belt. This belt replaces OEM part numbers 532405143, 21546607, and 584453101. It fits models like Craftsman 2246LS, 2346XLS, Husqvarna YTH22V46, YTH20K46, and Poulan YTH2146XP. Check your old belt’s length (measure end-to-end, not around pulleys) and verify your deck spindle pulley configuration (2-spindle vs 3-spindle models use different belts). Not compatible with zero-turn mowers or older 42" decks.

Key Things to Know

• Quality: Aftermarket belt; works for normal residential use but may wear faster than OEM under heavy or commercial conditions.
• Installation difficulty: Moderate–requires removing the deck or using a belt routing diagram. Use the deck’s tensioner lever to relieve tension (don’t pry).
• Common gotcha: If your deck has a spring-loaded idler pulley, ensure the belt routes correctly around it–wrong routing causes slipping or premature wear.
• Check pulley condition: Worn or rough pulleys will shred a new belt quickly. Replace any damaged pulleys at the same time.

Should You Buy It

If you need a budget-friendly, functional replacement for a 46" AYP-style deck belt on a residential lawn tractor, this is a solid pick. It’s not built for daily commercial use, but for typical homeowner mowing it delivers good value at $9.99–just verify your model number and belt length before ordering.
