The ease of use is made possible thanks to an anti-vibration system which completely isolates the handles from the rest of the machine; moreover, in the double blade version, with the machine set at idle, the handle can rotate by 180° so enabling the operator to also work easily on the sides of the hedges. Maximum safety is guaranteed by a patented automatic breaking device which is activated when the accelerator is released, causing the blades to come to a complete stop in less than one second, even maintaining the engine on minimum.
