Rau STF 301

The star tiller was developed in the 1990s by the Rau company in Weilheim (Teck) in southern Germany, to further reduce costs when sowing by plough. Two ground-driven star rollers with a tangential penetration angle of the tines ensure a breaking instead of cutting effect in the soil.
The Sterntiller was mostly driven as the STF 301 in front attachment. In this type, the rollers are oscillating and a height-adjustable leveling bar was available to level the area.
The Sterntiller is mainly used on heavy soils, as the rollers offer reliable self-cleaning and even hard clods are broken up reliably. It does good preparatory work for the rotary harrow or the tine rotor.
