The R versions - Great for heavy pruning
The R versions of the STIHL HS 81 and STIHL HS 86 are uncompromisingly designed for pruning. Their blade geometry has wide tooth spacing and a big cutter height. The gearing delivers high cutting power. The R versions therefore make all large-scale pruning and clearing work quicker and easier.
The T versions - Perfect for trimming
The T versions of the new STIHL hedge trimmers are designed for perfect shaping and fine trimming of hedges and shrubs. The blade geometry with a smaller tooth spacing and shorter cutter height in conjunction with the gearing for a high stroke rate helps to make a neat job even of "filigree" work.
