The Hermes Fisarmonica rotary mulching machine

Fisarmonica is the Italian word for accordion. This mulcher comes equipped with two lateral wings which can be hydraulically expanded and contracted and function independently of one another. This enables a continuously variable swath.
This machine is suitable for tractors from 50 to 110 HP and enables a high speed when cutting grass. The Fisarmonica is ideal for agricultural firms that have varying widths between the rows of trees, plants, vines etcetera, and are looking for a robust machine which is simple to operate. The machine can be equipped with a herbicide sprayer (with a container of 100 or 200 litres, depending on the model) or with a combined front and back attachment.
