OEM Husqvarna 587270101 Deck Belt Fits TS342 YT42DXLS YTH2642TDF TS343 TS242

What It Is

The Husqvarna 587270101 is an OEM (original equipment manufacturer) deck drive belt that transfers power from the engine pulley to the mower blades. Designed for 42-inch cutting decks on Husqvarna lawn tractors and zero-turn models, it replaces worn belts that slip, squeal, or snap.

Fitment & Compatibility

Before buying, verify your mower’s model number—this belt fits Husqvarna TS342, TS343, YT42DXLS, YTH2642TDF, and TS242 (all with 42-inch decks). Check your current belt for a part number stamped on the back; if it matches 587270101, you’re good. Measure the belt length (approx. 95.5 inches) and width (1/2 inch) to confirm. This OEM belt is a direct replacement—no modifications needed. It will not fit 46-inch or 54-inch decks. If your mower is a different brand (e.g., Craftsman, John Deere), cross-reference your model’s belt specs; aftermarket equivalents exist but may vary in tension.

Key Things to Know

• Quality: OEM Husqvarna belts are built with reinforced cords for longer life than many aftermarket belts. Expect 2-3 seasons under normal use.
• Installation: Moderate difficulty—requires removing the deck, routing around pulleys, and tensioning. A belt diagram (usually on the deck or in the manual) is essential. Allow 30-60 minutes.
• Common gotcha: If the belt squeals after install, check pulley alignment or debris in the deck. Worn idler pulleys can cause premature belt wear—inspect them while you’re at it.
• Price vs. aftermarket: At ~$38, it’s pricier than generic belts (~$15-25), but fit is guaranteed, and you avoid hassle from wrong sizing.

Should You Buy It

Buy this if you want a drop-in replacement with no fitment guesswork and prefer OEM durability over cheaper aftermarket options. It’s the right choice for Husqvarna 42-inch deck owners who value reliability and don’t want to risk a mismatched belt. If you’re on a tight budget or have a non-Husqvarna mower, look for a verified aftermarket alternative, but measure carefully.
