“I tried everything from cooking, cremating and catching weed seeds and discovered that crushing the seed consistently gave the best results.” – Ray Harrington, grain grower and inventor of the HSD.
Unlike other weed seed harvest systems, using the Harrington Seed Destructor (HSD) at harvest means there is no need for autumn burning, and chaff and weed nutrients remain in the paddock.
Ray stresses the HSD is not a silver bullet but it will make a difference to growers providing another tool to manage weeds and resistance.
“The HSD is no different to using a chaff cart – it’s the chaff cart evolved. You get the same end result but the HSD provides an easier way of getting there.”
