Since the summer of 2011, Herder BV has strengthened its product range with the Fermex stump grinders. The Herder plant in Middelburg will produce the stump grinders. This reinforces Herder's focus on providing solutions for the maintenance of landscapes and infrastructure. Fermex is a well-known brand in the maintenance industry. The machines are well-suited for rough work in the field or along roadsides. The Fermex machines are characterized by robustness and the low number of wearing parts, so high production is guaranteed.
