Rauch MDS 8.2 - Evaluate the Results and Correct if Necessary

Preparing three passages:
 Choose a similar fertiliser from the fertiliser chart and adjust the spreader ac-
cordingly.
 Set the mounting height of the machine as specified in the fertiliser chart.
Make sure that the mounting height includes the top edge of the trays.
 Check the spreading elements (spreading discs, spreader vanes, outlet) for
correct functioning and completeness.
 Place two collecting vessels each, one after another, at a distance of 1 m in
the overlap zones and in the centre track (according to figure 8.14
).
Run the spreading test with the open position that has been decided on for
operation:
 Forward speed: 3 - 4 km/h.
 Spread along the tramlines 1-3 one after the other.
 Open the metering slide 10 m in front of the collecting vessels.
 Close the metering slides approx. 30 m behind the collecting vessels.
8.5.4 Evaluate the results and correct if necessary
 Pool the contents of the collecting vessels placed one after another and pour
them into the measuring tubes from the left-hand side.
 The quality of the horizontal spreading pattern can be read off the three meas-
uring tubes.
Figure 8.15: Possible results of pass
[A] All tubes contain the same amount.
[B] Asymmetrical fertiliser distribution
[C] Too much fertiliser in the overlap zone
[D] Too little fertiliser in the overlap zone
NOTICE
If the quantity collected in the collecting vessels is insufficient, repeat the passage.
Do not change the adjustment of the metering slides.
