532144959 144959 Deck Belt Replaces Craftsman Drive Belt 160855 130801 138255, Fits Craftsman LT1000 LT2000 LT3000 DYT4000 Husqvarna Poulan AYP 42'' Lawn Mower (1/2" x 95")

What It Is

This is a 42-inch lawn mower deck belt (1/2" x 95") that drives the blades on select Craftsman, Husqvarna, Poulan, and AYP riding mowers. It’s a direct replacement for models like the LT1000, LT2000, LT3000, and DYT4000, as well as many other 42-inch cut machines.

Fitment & Compatibility

Before buying, measure your old belt to confirm it’s 1/2 inch wide and 95 inches long (these are critical specs). Check your mower’s model number (e.g., 917.xxxxx) or deck part number—this belt replaces OEM numbers 532144959, 160855, 130801, and 138255. It fits most Craftsman 42-inch decks from the late 1990s through early 2010s, plus many Husqvarna, Poulan, and AYP models with the same deck design. Not for 46-inch or larger decks, and not for zero-turn mowers unless explicitly listed.

Key Things to Do

• Measure your old belt length and width before ordering—some “42-inch” decks use different belt lengths (e.g., 92.5 or 96 inches).
• Installation is moderate difficulty; you’ll need to release the deck tensioner and route the belt around all pulleys, including the idler. A diagram helps.
• Check the belt for any fraying or cracking before installing—this is a budget-friendly aftermarket part, so inspect for defects.
• If your mower has a “spin-on” blade engagement system, verify the belt matches the OEM routing pattern (some aftermarket belts sit slightly tighter or looser).

Should You Buy It

Yes, if you need a reliable, low-cost replacement for a worn or broken 42-inch deck belt on a common Craftsman LT series or similar mower. It’s not the most durable option for heavy commercial use, but for home lawn care, it’s a solid value that fits most standard 42-inch decks. Just confirm your belt measurements and routing before cutting the old one off.
