Additional Information

Husqvarna blade drive belt 593773401 replaces part number 197242 and is designed to connect the engine pulley to the mower deck pulley, enabling the blades to rotate for consistent, even grass cutting. A properly functioning belt ensures efficient power transfer and smooth operation of the mower deck.

If your lawn tractor is cutting unevenly, the blades aren?t spinning, or you hear squealing from the deck area, the belt may be worn, stretched, or damaged. Replacing the belt can restore blade performance and prevent further drivetrain wear.

To install the new belt, start by turning off the engine, letting it cool, and disconnecting the spark plug wire. Use a wrench set to remove the necessary deck components and carefully route the new belt according to your model?s diagram. Always wear gloves to protect your hands during the repair process.
