B.4 Adjusting the application rate
B.4.1 Version D
You can set the spreading quantity of the machines of the versions D via the low-
er scale arc on both openings.
For this purpose, move the pointer to the position specified beforehand in the fer-
tiliser chart or from a calibration test. This is the Open stop position which the
slide approaches hydraulically or by spring force (depending on the version) while
spreading.
The position depends on the application rate and the forward speed.
1. Close the metering slide.
2. Determine the position for the scale setting in the fertiliser chart or based on
the calibration test.
3. Release the setscrew [2] at the lower scale arc [3].
4. Move the pointer [1] of the stop to the determined position.
5. Tighten the setscrew.
