What It Is

This is a V-drive belt for Husqvarna rear-wheel-drive (RWD) lawn mowers. It connects the engine pulley to the transmission, enabling self-propelled movement. Designed for residential mowers like the HU700H, LDC356VB, HU775BBC, HU775H, and HU775HW.

Fitment & Compatibility

• Direct OEM replacements: Husqvarna part numbers 532406557, 406557, and 583299101.
• Fits models: HU700H, LDC356VB, HU775BBC, HU775H, HU775HW. Confirm your mower’s model number on the deck or under the seat.
• Deck size: Works with 21” to 22” steel decks common on these Husqvarna RWD models.
• Cross-check belt length: Measure your old belt’s length (end-to-end, not looped). This belt is approximately 37.5 inches long. If yours differs, it won’t fit.
• Aftermarket note: This is a genuine Husqvarna belt, not a generic substitute. Aftermarket belts may vary in width or material, so stick with OEM for guaranteed fit.

Key Things to Know

• Quality: Genuine Husqvarna belt – reinforced rubber, resists stretching and cracking. Better longevity than most budget belts.
• Installation difficulty: Moderate. You’ll need to remove the mower deck and possibly the blade or pulley cover. A belt routing diagram is helpful (check your manual or online).
• Common gotcha: Don’t overtighten the idler pulley spring – it can damage the belt or pulley. Also, inspect pulleys for wear before installing; a rough pulley will shred a new belt fast.
• Price/value: At $8.99, it’s a steal for OEM quality. Cheaper than dealer prices but same part.

Should You Buy It

Yes, if you own one of the listed Husqvarna RWD mowers and need a reliable, direct-fit V-drive belt. It’s a solid value for the price, with proven durability from a major brand. Avoid if your mower uses a different belt length or is a non-Husqvarna model.
