Full field spreading
pattern test
If the spreader is correctly set and the tramlines are set at the correct
distance from each other you would achieve a good distribution of
fertiliser over the land. This will only be achieved if the spreader
spreads with the correct spreading pattern.
This is then the reason why you have to test the spreading pattern and
adjust it as required.

NDICATION
Always perform a calibration test first and determine the correct
dosing setting before checking the spreading pattern. Changes to the
dosing setting will also have an influence on the spreading pattern!
See paragraph »Calibration test« on page 93.
Operation
Switch the tractor off, remove the key from the ignition and engage
the parking brake of the tractor.
Set the spreader in accordance with the spreading chart for the
desired working width (X feet)
(height of the spreading disc = 29
1/2” above the troughs)
.
Place the grids in the troughs.
Place trough 1 in the middle of the tractor tracks.
I
NDICATION
Position the troughs horizontally with a spirit level!
Divide the additional 6 buckets on the one side of the track over the
actual working width of the spreader.
The actual working width is twice the size of the effective working
width!
If you want to spread over a working width of
•
40 feet, place the buckets at 40/6 = 6.67 feet.
•
49 feet, place the buckets at 49/6 = 8.15 feet.
Set the
PTO shaft rpm at 540 or 620 rpm.
Drive along the track and open the dosing unit at half working width
before you drive over the first trough in the middle.
