Make sure individual containers are level. Containers set at an angle can lead to mea-
suring errors.
♦
Set the spreader at the same height on the left- and right-hand side in accordance
with the information in the spreading charts, paying attention that the mounting
height is taken from the top edge of the collecting containers.
♦
Before testing, check the functioning and condition of the spreading elements
(discs, vanes, metering slides).
♦
Carry out a calibration check (see under "calibration check") possibly resetting the
left- and right-hand metering slides, locking in place with the handlock nuts. Make
first test using this aperture setting.
If it is felt that the fertilizer collected in the trays is not enough for a clear analysis
merely travel over the trays twice. Do not change metering slide aperture setting.
♦
Select only a tractor speed between 3 and 4 km/h so as to keep tractor and spreader
as steady as possible. Keep the metering slides to the same setting. It is irrelevant
to the test that the actual application rate is higher, as this is only a result of the
slower tractor speed for test purposes. Keep speed of tractor constant throughout
the test.
♦
Spread along the tramlines one to three, one after the other. Open the open/close
shutter slides approx. 10m before reaching the collection containers and close ap-
prox. 30m after passing them. If collected volume is insufficient, repeat all three
passes.
♦
Pool the contents of each pair of containers and pour into the respective measuring
tubes i.e. left-hand pair in left-hand tube, middle pair in middle tube, right-hand
pair in right-hand tube. The evenness of spread pattern can now be judged from
the level in each tube.
