4.7.1 Forward speed calibration
The forward speed calibration is the basic requirement for an exact spreading re-
sult. Factors such as tyre size, a different tractor, four-wheel drive, slippage be-
tween tyres and ground, ground characteristics and tyre pressure influence the
speed measurement and, therefore, the spreading result.
Preparing the forward speed calibration:
The exact calculation of the number of speed pulses over 100m is very important
for the precise discharge of the fertiliser quantity.

Conduct the calibration on the field. This reduces the influence of the ground
characteristics on the calibration result.

Determine a 100 m long reference track as precisely as possible.

Switch on four-wheel drive.

Fill only half of the machine, if possible.
Opening the forward speed settings:
In the QUANTRON-A control unit, up to 4 different profiles for the type and num-
ber of pulses can be saved. You can assign names to these profiles (e.g. tractor
name).
Before spreading, check that the correct profile is opened in the control unit.

1. Open the Machine settings > Tractor (km/h) menu.
The displayed values for name, origin and number of pulses refer to the pro-
file highlighted in black.
2. Press the function key ( F1-F4 ) under the memory location symbol.
