The agitator – soft-handling and gentle
The basic function of the agitator is to convey the fertiliser actively towards the outlet aperture so that a constant rate of fertiliser can be applied. Fertiliser lumps, which manage to pass the sieve, are, especially at low application rates, actively broken up via the star agitator which runs in the hopper bottom. If foreign objects reach the hopper tip and the agitator is overloaded, the electric motor reverses automatically in combination with the respective shutter and clears the fault. The perfect interplay of agitator and shutter is evident on the headland and in wedge shaped fields. As soon as one metering aperture is completely closed, the agitator above stops automatically. In this way the valuable fertiliser is protected from being ground up.
The benefits of electric agitation
- two slow-running, fertiliser-protecting agitators; turning at just 60 rpm
- that switch off automatically as soon as the shutter slide is closed, also just to the one side and independently of each other
- that reverse automatically when blocked by a foreign object
- active delivery of the fertiliser flow to the aperture
"A 12V motor drives the agitator which rotates at 60 rpm. It switches off when the shutter is closed and it reverses as soon as a foreign object blocks the agitator."
