Extending the setting range by moving the double chain wheel

To spread a higher seed rate, the setting range of the Vario gearbox can be extended or reduced with different types of gear wheels.

The installation position of the roller chain is marked with the numbers Z16 and Z34.

The roller chain runs either on chain wheel Z16 or Z34.

For certain seed rates, the double chain wheel Z16/34 can be replaced by the double chain wheel Z16/50.
