With reduced weight and an efficient EC-motor, the HSA 66 is quiet, light has increased cutting performance and maintains a constant stroke rate even during tough jobs. The wide tooth spacing and new droplet-shaped cutter geometry holds leaves and small branches more effectively in the teeth for a powerful cut. Machine life is also improved with a wear protective film under the cutting bar and new tip protector. The cutter blade is double sided.
We recommend AP100 battery for the HSA66, this will give you 72 mins of run time.
