Adjustments on fertilizer spreading are cen-
tralized in each fertilizer hopper of the plan-
ter. Fertilizer’s dosing device is adjusted by
turning its adjusting wheel (1, Fig. 6.119 ). The
adjusting scale has values from 0 to 30 (2, Fig.
6.119).
If the specic weight of the fertilizer to be
used is dierent from the ones in the dosing
tables, apply the following formula to calcu-
late the Kg/ha which are going to be spread:
WHERE:
Z = Kg/ha which are going to be spread.
V = Kg/ha in the table depending on the dosing adjustment, the row spacing and the fer-
tilizer’s specic weight shown in the table.
Weight
T
= specic weight shown in the table depending on the selected value “V”
Weight
R
= actual specic weight of the fertilizer.
In case of fertilizing at a dierent row spacing from the ones in the dosing tables, apply the
following formula:
WHERE:
Z = Kg/ha which are going to be spread.
V = Kg/ha in the table depending on the dosing adjustment, the row spacing and the fer-
tilizer’s specic weight shown in the table.
D

= row spacing shown in the table.

DESIRED
= desired row spacing.
VERY IMPORTANT:

IT IS NOT RECOMMENDED TO USE VALUES UNDER 10 IN THE ADJUSTING SCALE, SINCE THEY
MAY RESULT IN IRREGULAR SPREADING DUE TO THE FERTILISER’S GRAIN GEOMETRY.
THE MACHINE COMES ASSEMBLED WITH A DISTANCE BETWEEN FERTILIZERS FROM 5 TO 9 CEN-
TIMETRES IN RELATION TO THE PLANTING ROW.
BEFORE START PLANTING, MAKE SURE THAT THE DISTANCES BETWEEN PLANTING ROWS AND
FERTILIZER ROWS ARE CORRECT.
