The humus PS undergrowth mulcher impresses with its light weight and high performance in forestry and municipal applications (keeping roads clear, clearance, forest residues, etc.). The humus PS undergrowth mulcher is also perfectly suited for use in traditional agriculture (conversion of overhanging orchards or similar).

There are extra costs for the mounting to the carrier vehicle! Mounting has to be run by retailers. When ordering please specify oil quantity and oil pressure.Delivery without hydraulic hoses.

In recent years, the use of these devices has changed. They are often used as carrier vehicles (sometimes radio-controlled or even autonomous tracked vehicles) for instance on steep slopes, i.e. in places where a conventional towing vehicle, such as a tractor, can no longer be used because of its size and weight. Thanks to the lower power of such a tracked vehicle compared to a conventional towing vehicle, the previously existing and often very massively built forestry and scrub mulchers can no longer be used since they are too heavy.

For this reason, our humus designers made every effort to meet these requirements and developed our humus PS, a very light yet powerful undergrowth mulcher.
