The controller connected to the hydraulic motor allows, depending on its position, setting the internal
pressure in the distribution lines. A pressure gauge installed on the tank (from the tractor side) allows
determining this pressure.
The turbine speed must be set depending on the type of seeds to be sown and the working width. For
orientation:
see Table below:
Working width
3m
4m
6m
Fine seeds:
3-4 kPa
4.5 kPa
4.5 kPa
Coarse seeds:
4 kPa
5.5 kPa
6 kPa
In order to change the speed of the turbine, use the hydraulic controller (see Fig. 2). Use the knob to set
the delivery.
Ensure that the turbine speed setting is approx. 50 %, start the hydraulic distributor of the tractor in the
position of continuous opening. The turbine must rotate.
Otherwise, check the hydraulic system and ensure that the oil return is set to the tractor free oil return.
Restart the tractor hydraulic distributor in its continuous opening position. The turbine must rotate.
