AutoSectionControl (ASC) is a fully automatic system that opens and closes boom sections as necessary. ASC manages the sections when driving over sprayed area like into a headland or wedge or around obstacles like trees etc.
HC 8600/HC 9600 have ASC as a standard feature and only need to be connected to a GPS receiver. When spraying, the ASC automatically records the area sprayed. In a typical situation where the headland is sprayed first, ASC will now automatically close the sections if the operator passes over a sprayed area.
