Additional Information

The Husqvarna Lawn Tractor Primary Blade Drive Belt, part number 532139573, transfers power from the engine pulley to the mower deck, turning the blades to deliver a clean, consistent cut. This belt replaces the previous part number 139573 and is designed for long-lasting performance in demanding mowing conditions.

If your lawn tractor blades won?t spin, cut unevenly, or stop mid-mow, a worn or broken drive belt might be to blame. Replacing the belt restores full blade engagement and keeps your mower running smoothly.

Before starting the replacement, disconnect the spark plug wire and wear work gloves to avoid injury from sharp blade edges or moving parts. Remove the mower deck and use basic hand tools to install the new belt, ensuring it's correctly routed around all pulleys for proper tension and operation.

Routine inspection and timely belt replacement helps extend the life of your lawn tractor and maintains optimal mowing performance throughout the season.
