What is the Accu-Spread Testing Process?
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.
How Do I Arrange Accu-Spread Testing?
Accu-Spread® testing and certification is available to all professional fertilizer spreading contractors.
Independent, certified spreader testing officers undertake the testing. To arrange Accu-Spread testing, contact one of the current testing officers listed in the file below
The cost of the testing and any associated travel etc is agreed between the machine owner and the Accu-Spread testing officer. Typically a machine is tested with three different products, however more products can be tested by arrangement with the Testing Officer. Members of AFSA and Fertilizer Australia enjoy an Accu-Spread testing discount of $350 per machine as a benefit of membership.
Modifications to improve the performance of spreaders can be undertaken by some testing officers; the costs associated with any modifications or repairs to the spreader are agreed between the parties.
Each AFSA Branch has a trailer fitted out with trays, scales and measuring cups to enable businesses to test their own machines prior to being officially assessed by an Accu-Spread Testing Officer. The Accu-Spread model is available for a fee here.
The challenge with self-testing is to understand the graphs and to be able to use that information to improve the performance of your machines.
To access the trailers, contact your Branch Secretary.
