5.3 Spreading with automatic operating mode (AUTO km/h + AUTO kg)
Mass flow control with the M EMC function
Mass flow is measured separately on both spreading disc sides. Thus deviations
to the specified application rate can be immediately corrected.
The M EMC function requires the following machine data for mass flow control:

PTO speed

Spreading disc type
A PTO speed between 450 and 650 rpm is possible.

The desired speed should remain constant during spreading (+/- 10 rpm) .
High control quality can therefore be ensured.

The idle measurement is only possible if the actual PTO speed deviates by
max. +/- 10 rpm from the entry in the PTO menu. Outside of this range, idle
measurement is not possible.
Precondition for spreading:

The AUTO km/h + AUTO kg operating mode is active (refer to 4.7.2: AU-
TO/MAN mode, page 58 ).
1. Fill the hopper with fertiliser.
2. Adjust fertiliser settings:

Application rate (kg/ha)

Working width (m)
3. Enter the PTO speed in the corresponding menu.
See also “PTO shaft“ on page -49 .
4. Select the spreading disc type used in the corresponding menu.
See also “Spreading disc type“ on page -49 .
5. Switch on PTO shaft.
6. Set PTO shaft to the PTO speed entered.
 The Idle measurement screen is displayed.

7. Wait until the progress bar has entirely passed through.
 Idle measurement is finished.
 Idle time is reset to 20 min.
