Husqvarna Pro Straight Shaft Trimmer 525LST


Cut your workload with the ultra-efficient Husqvarna 525LST trimmer. The 525LST features a powerful and fuel-saving X-Torq® engine. Under the high-visibility guard spins 19 inches of cutting line driven by a powerful gearbox capable of accommodating longer line length and higher RPMs. Compared to the 17-inch cutting swath of competitor trimmers, the 525LST has the largest cutting width in its class.* The durable T35X head features a ball bearing design that enables the bottom bump to spin freely of the head creating less friction and less maintenance. At under 10 pounds, the class-leading 525LST is lightweight while featuring durable armor plating and a 7-spline solid shaft. Husqvarna’s LowVib™ design with rubber isolation in the handle delivers comfortably low vibration levels. The perfect finish to any job starts with Husqvarna’s 525LST.
