The Stihl HSA 86 Battery Hedger Trimmer is lighter and even more powerful and efficient than its predecessor. It ensures a constant stroke rate while pruning thick hedges. The STIHL EC motor also guarantees a longer running time while keeping noise to a minimum. 33mm tooth spacing and larger intervals on the cutting guard make light work of thicker hedges. The cutter blade is double-sided with double-edged cutting teeth for a precise finish.
