Stihl HS81R hedge cutter with double edged blade and slower more powerful cutting action. This is a great new machine from Stihl, great design and a real workhorse. Powered by a 22.7cc two stroke engine producing 1.0 bhp. The machine has very low vibrations due to the new anti vibration system fitted to this machine. The exhaust gases are now ported to the front of the machine to avoid the operator and reduce inhalation of fumes. A great machine and we have had no negative feedback on this new model.
