When you want maximum productivity from a trimmer, Husqvarna’s 525LS is the way to go. The 525LS delivers the best power-to-weight ratio in its class*, featuring a powerful and fuel-saving X-Torq® engine. The durable T35X head features a ball bearing design that lets the bottom bump spin freely of the head, creating less friction and less maintenance. At under 10 pounds, the 525LS 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. If you’re looking to maximize your productivity, put a 525LS in your landscaping trailer or shed. (*Based on weight of tool without fuel. Ratio calculated using weight (lbs.) and engine horsepower. Class defined as pro-grade petrol trimmers with engine displacement in the 20cc to 29cc range.)
