Humus is the product range from Maschinenfabrik Bermatingen and STM represent them in the UK. There are three main product areas: Rotary Decks, Flail heads and their specialised product – The Safety Mulcher.

Rotary decks are tractor mounted front or rear and include fixed deck widths plus models with swing out heads. The AFLR has a single such head and is popular for use around fence posts or on solar farm installations.

Flail heads are heavy duty construction and provide high performance. There are “Y” type blade systems, or a comprehensive set of claw flails.

The Safety Mulcher system features a patent cutting system. There is a flail-head type rotor, but it has a series of toothed spiral plates fixed to it to create a spiral. This spins at high speed and very effectively cuts down grass and brush, whilst having a the dual safety aspects of 1) riding over anything that is too solid to cut, and 2) ejecting small debris items safely at the side by way of the spiral action.
