144959 Riding Mowers Deck Belt 42" for Craftsman LT1000 LT2000 LT3000 DYT4000 160855 130801 138255 Replaces Husqvarna Poulan AYP Lawn Mower 138255 532144959 532138255

What It Is

This is a 42-inch replacement deck belt for select Craftsman, Husqvarna, Poulan, and AYP riding mowers. It drives the mower deck blades from the engine pulley and is designed for residential use on 42-inch cutting decks.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be a 42-inch (actual cut width) deck—this belt will not fit 46-inch or 54-inch decks.
• Model series: Fits Craftsman LT1000, LT2000, LT3000, and DYT4000 series with a 42-inch deck. Also fits select Husqvarna, Poulan, and AYP models using OEM numbers 138255, 144959, 532144959, 532138255.
• Belt specs: 1/2-inch width, 92.3-inch effective length. Measure your old belt or confirm your mower’s owner manual lists these numbers. Cross-check your model number on the manufacturer’s site or a parts lookup tool—don’t rely solely on the “fits” list.

Key Things to Know

• Quality: Aftermarket belt, not OEM Craftsman. Users report it’s durable for residential use but may wear faster than OEM under heavy or daily commercial cutting.
• Installation: Moderate difficulty. You’ll need to remove the mower deck and route the belt around pulleys and tensioners—a diagram is helpful. Expect 30–60 minutes if you’re handy.
• Gotcha: The belt may be slightly tighter than OEM. If your tensioner is worn or stuck, you might struggle to install it. Check tensioner spring condition first.
• Price: At ~$14.55, it’s about half the cost of an OEM belt. Good value if you’re on a budget and mow a standard residential lawn.

Should You Buy It

Buy this if you need a reliable, low-cost replacement for a 42-inch Craftsman or compatible mower deck and you’re comfortable with a DIY install. Skip it if you mow commercially, have a worn tensioner, or want OEM exact-fit—spend the extra $10-15 for a genuine Craftsman belt.
