The system is capable of spraying up to five different herbicides simultaneously. Not trailers are needed for this spray system. The fourth sprayer is the SCS 750, which was developed by Raven Industries Inc. of Sioux Falls, South Dakota. The SCS 750 can independently control the liquid, and granular dispensing systems and the overall hydraulic system at the same time. If spot spraying is need, each chemical can be controlled by a manual switch.
Hand spraying attachments also are available for spot spraying.
The spray rate is controlled by a wheel driven speed sensor. Visual and audible alarms alert the operator to any deviation from the programmed rate of application. Measurements can be calculated using the metric or U.S. measurement systems. Calibrations and weather information are stored in the ten-year memory capacity. A compact printer is plugged into the 750 console to obtain a readout of the daily activities.
