Eliminate fuel costs and get the convenience of lithium-ion technology with the battery-powered HTA 66. This fixed-length pole pruner is a cordless, low-maintenance, and environmentally responsible option for professionals and homeowners alike. Running on an advanced 36-volt lithium-ion battery, the HTA 66 eliminates the need for fuel and two-cycle oil and considerably reduces maintenance needs. It offers you low noise and lower vibration levels than its gas-powered equivalents, as well as automatic chain oiling—making it the perfect pruner for many tree-care needs. The robust branch hook allows for the easy removal of loose clippings from trees up to 12-feet high, and the variable-speed trigger offers three performance settings for maximum efficiency and effectiveness. STIHL lithium-Ion batteries are designed to be swapped between multiple STIHL AP System battery-powered tools, so you can use a single battery to tackle a wide range of outdoor projects. 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. This tool is IPX4-rated for weather-resistant construction and has been designed and tested for splash-water protection.
