History

After trying cooking, catching, cremating, he settled on crushing, or a variation thereon and adapted the cage mill taken from the mining industry to reduce coal to powder. HSD technology was born.

The chaff stream from a combine harvester is intercepted and fed directly into a high speed mill that pulverises the chaff, which includes weed seeds that would otherwise pass through the harvester and be returned to the field. The Australian Grains Research and Development Corporation (GRDC) understood the importance of Ray Harrington’s endeavour and commitment to design a machine capable of destroying weed seeds prevalent in the waste from the harvesting process. GRDC provided funding and UniSA provided research and development expertise to further develop HSD technology.

The first tow-behind HSD units were developed commercially by de Bruin Engineering and won the prestigious Edison Award for Smart Agriculture but the tow behind unit was quickly overshadowed by the promise of HSD technology integrated right onto the harvester. Finally, after years of research and development by UniSA funded by GRDC, through many trials by and tribulations HSD technology entered its ultimate phase – the Integrated Harrington Seed Destructor – iHSD V12.
