One summer’s day, a Sapphire engineer stubbed out his cigarette on a stubble field, using a circular motion with the sole of his shoe. He then noticed that the stubble was frayed and crushed.
This observation gave rise to the idea of building a grinding device. This was followed by many years of practical attempts to use this grinding principle after harvesting various crops.
After the benefits of the functional principle were confirmed in an initial master’s thesis, the subsequent collaboration with the Institute for Construction and Agricultural Machinery Technology at the University of Applied Sciences, Cologne, the design partner seed2soil and financing from the (agricultural) Landwirtschaftliche Rentenbank helped us develop a completely new tool for ultra-flat stubble and tillage.
The result is now the patented GrindStar® system.
