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:
www.bogballe.com
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).
SPREAD WIDTH
(metres
)
TRAY DISTANCE
(metres)
12 1,5
15-16 2,0
18 2,5
20-21 3,0
24 3,5
27-28 4,0
30 4,5
32-33 5,0
36 5,5
42 6,5
For each 3 metres spread width – the
distance between the single trays is
increased by 0,5 metre.
•
Start spreading minimum 10
metres before the row of trays.
•
Stop spreading minimum 35
metres after the row of trays.
•
Spread in 3 tramlines.
•
Empty contents of each tray
down in each a measuring tube
and see the result.
