The Integrated Harrington Seed Destructor (iHSD), which comprises two hydraulically-driven cage mills mounted to the rear of a harvester, allows one-pass weed control.

Darryl Verburg, iHSD sales representative in Australia with McIntosh Distribution, said the enhancements focus on improving the iHSD’s cooling capacity; adjusting the chute design to allow better feeding into the mills and accessibility to the sieves; and setting up the hydraulic system to constantly provide 3000 RPM, enabling material to move freely through the mills.

Verburg said the coolers were also now easier to clean out, with double swing-out doors, while the new chute design allowed switching from cereals to pulses without any changes.

Other enhancements include different oil cooler particle screening options, including a fixed or rotary screen, and simplified user interface on the in-cab control, display and monitoring system.

The effectiveness of the iHSD has now been tested with 25 weed seed species. Research undertaken by the Australian Herbicide Resistance Initiative (AHRI) has determined the mills can destroy 93-99 per cent of weed seeds, preventing most from entering the soil.

The iHSD will be on display at major agricultural field days across the country this year.
