AIPICO's replacement drive belt and idler pulley kit restores reliable deck drive performance for Husqvarna HU800AWD, HU725AWD, HU675AWD and compatible models.

If your walk‑behind Husqvarna mower is slipping, making unusual noises, or losing cutting drive, this aftermarket kit provides the common wear parts needed to get the deck running smoothly again. The set includes one drive belt and three idler pulleys engineered for durability and correct tensioning on the specified Husqvarna models and part numbers 580364603, 580364602, 580364610, 587973001. It’s a straightforward maintenance option for those who want to replace worn components without buying OEM assemblies at higher cost.

How will this kit fix a slipping or noisy mower deck?

The included idler pulleys take up slack and maintain belt alignment while the drive belt transmits power from the engine to the cutting blades. Replacing both belt and pulleys together eliminates common mismatch failures caused by a good belt running on worn pulleys or vice versa. A fresh kit reduces belt chatter, vibration, and the tendency for the belt to walk off the pulleys.

• One drive belt sized for Husqvarna walk‑behind decks
• Three idler pulleys to restore correct belt tension
• Improved alignment reduces squeal and slipping
• Durable materials resist wear and extend service life

What are the materials and build features to expect?

The belt is manufactured to withstand the heat, flexing, and abrasion typical of lawn mower deck drives. The idler pulleys use wear‑resistant materials and bearings suited to rotational loads and intermittent exposure to turf debris. Together, the components are designed for dependable tension control and long service intervals under normal mowing conditions.

• Idler pulleys with robust bearings for smooth rotation
• Engineered to hold correct tension and alignment
• Aftermarket quality built to reduce frequent replacements

How simple is the installation for a DIY mower owner?

Installation is straightforward for anyone comfortable with basic mower maintenance: remove the deck, note belt routing, swap old pulleys and belt for the new components, and reassemble. No specialized tools are typically required beyond standard wrenches and perhaps a socket set. If unsure, refer to your mower’s service manual or consult a small‑engine technician.

• Remove deck to access belt and idler pulleys
• Follow belt routing diagram or photograph before removal
