144959 Deck Belt - Compatible with 42" Deck Craftsman LT1000, LTX1000, LT2000, 917 Tractors & Pou LAN Pro PD185H42ST Riding Mower, Hus qvarna Lawn Mowers, Durable Replacement Belt for Smooth Operation

What It Is

This is a replacement deck belt (OEM cross-reference 144959) for 42-inch cutting decks on select Craftsman LT1000/LTX1000/LT2000/917 series tractors, Poulan Pro PD185H42ST, and some Husqvarna riding mowers. It drives the blade spindles from the engine pulley.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 42 inches (measured blade tip to blade tip).
• Belt length: This belt is 92.5 inches long, 1/2 inch wide. Measure your old belt or check your owner’s manual.
• Model number: Craftsman 917.xxxxx series (check plate under seat). Not for 46-inch or 54-inch decks. Poulan Pro PD185H42ST is a direct fit; Husqvarna models with 42-inch decks and compatible PTO systems may also work—verify belt routing diagram online.

Key Things to Know

• Aftermarket quality: At $10.99, this is a budget belt. Some users report shorter lifespan than OEM (1-2 seasons vs. 3-4). Inspect for cracks or fraying after heavy use.
• Installation difficulty: Moderate. You’ll need to remove the deck or use a belt tool to route around idler pulleys. Watch a YouTube video for your specific model—routing errors cause immediate slipping.
• Common gotcha: Belt tension matters. If your idler spring is weak or pulley bearings are worn, the belt may squeal or throw off. Replace worn pulleys at the same time.
• Not universal: Even if the length matches, some Craftsman 42-inch decks use a different belt (e.g., 130794 or 132959). Double-check your old belt’s part number.

Should You Buy It

This belt is a decent budget option if you need a quick replacement for a 42-inch Craftsman, Poulan Pro, or compatible Husqvarna rider and you’re comfortable with moderate DIY installation. It’s not ideal for heavy commercial use or if you want OEM longevity—spend more for a Gates or OEM belt if you expect years of service. For occasional home mowing, it’ll get the job done.
