2PK 144959 532144959 Deck Drive Belt (1/2" × 95") Compatible with Craftsman LT1000 LT2000 LT3000 DYT4000 42-inch Deck Riding Mowers - Fits Husqvarna Poulan AYP Lawn mowers Belts 532138255 138255-Green

What It Is

This is a 2-pack of 1/2-inch wide, 95-inch long deck drive belts designed for 42-inch cutting decks on Craftsman LT1000, LT2000, LT3000, and DYT4000 series riding mowers, plus select Husqvarna, Poulan, and AYP models. It transfers power from the engine pulley to the mower deck spindles to spin the blades.

Fitment & Compatibility

Before buying, confirm your deck is 42 inches and your current belt measures 1/2" wide by 95" long (or part numbers 144959, 532144959, 532138255, or 138255). This belt replaces OEM Craftsman, Husqvarna, Poulan, and AYP belts with those numbers. It does NOT fit 46-inch or 54-inch decks, nor older Craftsman models with a different belt routing. Check your mower’s deck belt diagram—some LT series use a separate drive belt for the transmission; this is only for the deck blades.

Key Things to Do

• Measure your old belt – Even if the part number matches, a worn belt can stretch. Lay it flat and measure end-to-end; it must be 95 inches.
• Check pulley condition – Worn or rusty pulleys will eat a new belt quickly. Clean and inspect before installing.
• Install tension correctly – This belt runs under the deck, often routed around a tensioner pulley. Use the deck’s belt diagram (usually under the seat or deck cover) to avoid misrouting.
• 2-pack value – You get two belts for the price of one OEM. Keep the spare for next season—deck belts typically last 1-2 years with regular use.

Should You Buy It

If you have a 42-inch Craftsman LT1000-3000 or compatible AYP/Husqvarna rider and want a reliable, affordable replacement that matches OEM specs, this 2-pack is a smart buy. It’s not for odd-sized decks or non-standard belt lengths, but for common 42-inch decks, it’s a solid, cost-effective choice.
