7 - ADJUSTMENTS
A - Capacity adjustment
1.
Adjust the position of lever opening the port according to: the quantity to be spread, the tractor
speed and the fertiliser used by placing the index from 0 to 10 for models working with spreading
disc and from 0 to 9 for models working with an oscillating tube.
2.
To achieve a uniform capacity keep a constant forward speed.
3.

Table For Oscillating Bar Type Models
The graded scale comprises three lines of holes marked with the letters R, S and T. Each line consist of 9 holes, which are out of line with the
holes of the previous line by half a diameter. This system allows simple but effective adjustment with 27 different fertiliser quantity settings.
The exact hole into which the pin should be inserted can he obtained from the spreading table used as shown in the example.
