Constructed with aramid tensile cords, a reinforced rubber body, and a two-layer cover, the belt is built to resist wear and handle the tension and flex of deck pulley systems. It’s produced to tight tolerances (±0.50\" length variance) and lab-tested for low friction and high breaking strength so you can replace a worn strap without compromising reliability.\u003c\/p\u003e\n\n\u003ch3\u003eWhich mower models will this 5\/8\" × 163\" belt fit?\u003c\/h3\u003e\n\u003cp\u003eThis belt replaces Husqvarna OEM numbers 539104335 and 522795901 and fits a broad set of Husqvarna deck sizes and part configurations.
