The testing involves driving the spreading machine over a line of at least 50 equal-sized and spaced collection trays, while the machine is discharging product. The content of each collection tray is then weighed, noting the location of each tray in relation to the centre of the spreader. The data is entered into a computer program which calculates the CoV for various bout widths presenting this information in a graph. The graphs inform the operator the bout width to produce an acceptable spread pattern.
The Accu-Spread model calculates the bout width to achieve an acceptable spread pattern. Whilst anyone is able to use the model for a fee, if Accu-Spread certification is required, equipment must be tested by an Accu-Spread Testing Officer. To access supporting information and the model, click here
