Homeowners and tree care professionals now have a quiet, zero-exhaust emission, low vibration option for trimming overhead branches. The HTA 85 Lithium-Ion battery pole pruner offers lightweight, balanced cutting thanks to its brushless, commercial-grade, high-torque electric motor. Part of the STIHL AP series, the HTA 85 offers long run times – up to three hours with the AP 300 battery – without gradual drop in performance. The HTA 85 telescopes to 12 feet for those tall tree-trimming tasks and requires minimal maintenance since it has no engine or filter. Best of all, there’s no gasoline cost and no restrictive power cords.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.
