144959 532144959 Deck Belt Replaces for Craftsman LT1000 LT2000 LT3000 DLT3000 DYT4000 Husqvarna Poulan AYP Ariens Riding Lawn Mower 42 Inch Deck Belt 138255 532138255 (1/2" x 95") - Green

What It Is

This is a 42-inch deck drive belt (1/2" x 95") that transfers power from the engine pulley to the mower blades on select Craftsman, Husqvarna, Poulan, AYP, and Ariens riding mowers. It’s a direct replacement for OEM part numbers 144959 and 138255.

Fitment & Compatibility

Before buying, confirm these three things:

• Deck size: Only fits 42-inch cutting decks. Measure your belt length—must be exactly 95 inches (end to end, not looped). Width must be 1/2 inch.
• Model series: Compatible with Craftsman LT1000, LT2000, LT3000, DLT3000, DYT4000, and many Husqvarna/Poulan/AYP/Ariens models with 42" decks. Check your owner’s manual or look up your mower’s model number (starts with 917 or 247) on the manufacturer’s site.
• OEM vs. aftermarket: This is an aftermarket belt, not OEM Craftsman. It’s functionally identical but may differ slightly in rubber compound or flex. If your mower uses a 1/2" x 95" belt (not 3/8" or 5/8"), this will work.

Key Things to Know

• Quality: Most users report decent durability for the price, but some note it wears faster than OEM on heavy-use or rough terrain. Expect 1–2 seasons under normal cutting conditions.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the belt covers. Use the routing diagram printed on the deck or in your manual—wrong routing causes belt slip or breakage.
• Common gotchas: This belt is green (not black like OEM). Don’t confuse it with a 95-inch drive belt for a 46" or 50" deck—measure twice. Also check that your deck spindles spin freely; a seized spindle will shred any belt quickly.
• Return policy: Since belts are wear items, confirm the seller accepts returns if it doesn’t fit. Some sellers exclude belts from returns.

Should You Buy It

This belt is a solid budget pick for DIY homeowners with a 42-inch Craftsman or compatible mower who need a quick, affordable replacement. It’s not built for commercial use or heavy-duty conditions, but for routine lawn care it delivers reliable performance at a fraction of OEM cost. If you mow large, rough properties or want maximum longevity, spend more on an OEM belt instead.
