The HLA 85 STIHL Lithium-Ion extended reach hedge trimmer offers lightweight, balanced cordless trimming thanks to its brushless, high-efficiency electric motor. It features a variable speed throttle trigger and an articulating gearbox (-45° to 70°) for cutting the tops of hedges and near the ground. The HLA 85 is also extremely quiet and produces zero exhaust emissions – great for working in noise-restricted areas. Best of all, there’s no fuel cost, minimal maintenance and no restrictive extension cords. And like all STIHL battery-powered tools, the HLA 85 offers exceptional run times (up to 11 hours with the AR 900 backpack battery) with no gradual drop in performance.Run time may vary based on battery type, charge level and capacity, model, operating style and conditions. Batteries and chargers can be purchased separately or as a combined set with tool.
