HSA 66 Hedge trimmer
Handy cordless hedge trimmer with 20" / 50 cm blade length
Overview
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.
