Husqvarna 587686701 Genuine OEM Belt

What It Is

The Husqvarna 587686701 is a genuine OEM drive belt designed to transfer power from the engine to the mower deck blades on select Husqvarna zero-turn and lawn tractors. It’s a replacement belt for models in the Z200, Z400, and TS series, among others.

Fitment & Compatibility

Before buying, confirm your mower’s deck size (usually 42", 46", or 48") and model number – this belt fits specific decks, not all Husqvarna models. Check the OEM part number against your old belt’s number (often printed on the belt itself). This is a genuine Husqvarna part, not aftermarket, so it’s a direct replacement for the original. Measure your old belt’s length (approx. 105" for many 42" decks) and width (typically 1/2" or 5/8") to ensure match. Avoid generic “fits Husqvarna” belts unless you verify exact measurements.

Key Things to Know

• Quality: Genuine OEM means better durability and fit than most aftermarket belts, reducing slippage and premature wear.
• Installation: Moderate difficulty – you’ll need to remove the mower deck, route the belt around pulleys, and re-tension. A diagram (check your manual) helps avoid misrouting.
• Common Gotcha: Belts can be tight on new pulleys; use a belt tool or breaker bar for tensioning. Don’t force it – incorrect routing causes rapid wear or deck damage.
• Check Pulleys: Worn or misaligned pulleys will destroy a new belt quickly. Inspect and replace if needed.

Should You Buy It

Buy this belt if you have a compatible Husqvarna model and want a reliable, OEM-spec replacement that matches original performance and lifespan. It’s best for DIY owners who can handle deck removal and belt routing, and who prefer not to gamble with cheaper aftermarket options. If you have an older mower with worn pulleys, address those first.
