Following results are possible
:
A
Same quantity in all three tubes
(allowed tolerance ±1 mark)
The spread pattern is acceptable.
B
Lop-sided spread pattern.
Unacceptable.
C
Too much fertilizer in the overlap zone.
Unacceptable.
D
Too little fertilizer in the overlap zone.
Unacceptable.
Hints for correcting the spread pattern
If results are obtained as shown in example B , check that both right- and left-hand
metering slides open exactly equally. Check that the output points on each disc are
set exactly equally. Check that the spreader is set exactly horizontally. Check that the
tramline widths are equally spaced and parallel, even a slight error with one tramline
being closer to another will cause a poor result. Has there been a cross wind during
the test run ?
If the results are obtained as shown in example C , an earlier output point should be
selected so that the fertilizer in the overlap zone is reduced.
(
Example : adjust from OP 5 to OP 4).
If results are obtained as shown in
example D , a later output point should be selected
so that fertilizer in the overlap zone is increased.
(
Example.: Adjust from OP 8 to OP 9).
