Fig. 11: Test result D
[[D]] Too little fertilizer between the track and the
overlap zone.
Examples for the correction of the spreader setting:
Fertilizer distribution
With limited working width and with fertilizers with
good flying properties, large overlap zones result
(spreads approximately into the next track).
Objective: Triangular spreading pattern
Reason:
Total spreading width too small, therefore higher speed. Due to the higher speed, the fertilizer is
released from the disc sooner, therefore select the feed point later.
With larger working widths of approx. 24 m and
more and with fertilizer with poor flying properties,
small overlap zones result (spreads slightly wider
than the working width). Objective: Trapezoidal
spreading pattern
Reason:
Total spreading width too large, therefore lower speed. Due to the lower speed, the fertilizer is
released from the disc later, therefore select the feed point sooner. If the deviations are relatively
small, a speed reduction only without feed point adjustment may also be sufficient.
Always test step-by-step: First feed point, then the speed.

5. Evaluating the results and correcting them if necessary
Measure, test
Select setting of feed point later (e.g. feed point
adjustment from 8 to 9).
Increase PTO speed setting (e.g. adjustment from
540 to 570 rpm).
Select setting of feed point sooner (e.g. feed point
adjustment from 9 to 8).
Reduce PTO speed setting (e.g. adjustment from
570 to 540 rpm).
