180808 Secondary Deck Belt Fit for 48" Mower Deck, Replaces for AYP/Craftsman/Husqvarna 174369 33908 531300771 532180808, 89" Kevlar Belt

What It Is

This 89-inch Kevlar-reinforced secondary deck belt drives the blades on 48-inch mower decks for AYP, Craftsman, and Husqvarna lawn tractors. It’s the belt that connects the blade spindles, not the primary drive belt from the engine.

Fitment & Compatibility

Before buying, verify three things:

1. Deck size must be 48 inches – this belt is not for 42-inch or 54-inch decks.
2. OEM part numbers to match: Replaces 174369, 33908, 531300771, and 532180808. If your mower uses any of these, it fits.
3. Measure your old belt: It should be 89 inches long (outside circumference) and 1/2 inch wide. If your belt is shorter or wider, this won’t work.

Common models using this belt include Craftsman T110, T120, T150, T160, and Husqvarna YTH1542XP, YTH18542, and YTH22V46. Always check your mower’s model number or the existing belt’s part number—don’t rely on brand alone.

Key Things to Know

• Kevlar construction is more durable than standard rubber belts, resisting stretching and heat better. Expect longer life if you mow thick or damp grass.
• Installation is moderate difficulty – you’ll need to remove the deck or at least the belt guard, and possibly a pulley to slip the belt on. A belt tool or pry bar helps.
• Common gotcha: This is the secondary belt (deck only). If your mower won’t move forward, you need the primary drive belt, not this one.
• Check pulley condition before installing – worn or rough pulleys will shred any belt quickly. Replace damaged pulleys first.

Should You Buy It

If you need a direct replacement for a worn secondary belt on a 48-inch AYP/Craftsman/Husqvarna deck and want better durability than a standard rubber belt, this is a solid, well-rated choice. Avoid it if your deck is a different size or you’re unsure whether it’s the secondary belt—measure first.
