TEST WITH TEST TRAYS

For a practical test in the field it is possible to use test trays in order to ensure a correct
spread width and thus an optimum overlap.
The tray test must be made with great care as wrong placement of the test trays may result
in faulty measuring and faulty setting of the machine.
BOGBALLE recommends normally only to use test trays in case the fertiliser type spread
is not found in the spread chart or in case you are not sure about the quality of the fertiliser.
On the Internet you will find the latest spread charts updates on our home page:
Included with the test trays you will find a description how to use them. Below you will
find a short description with an example of an 18 metres system where 7 test trays are used
and where the result is measured by means of 7 measuring tubes:
•
Place the test trays in an even line across the driving direction.
•
It is essential that the trays are placed HORIZONTALLY. (Use level).
For each 3 metres spread width – the
distance between the single trays is
increased by 0,5 metre.
