The HSA 66 STIHL Lithium-Ion hedge trimmer offers professional-grade power and all the convenience of the STIHL Battery-Powered Equipment: No gasoline. No cord. No exhaust emissions. This cordless hedge trimmer is powered by 36-volt STIHL Lithium-Ion battery technology and runs up to 40% longer than the previous model. It is also a full pound lighter than the previous model, making it even easier to use and maneuver when on the job. The HSA 66 is also four times quieter than its gasoline-powered equivalent. The tooth spacing and diamond-ground blade edges mean cleaner cuts, and with high cutting speeds, professionals can complete more hedge trimming in a short amount of time. 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.
