The MODULA is a precision seed drill, innovative and multi-purpose, suited for biological agriculture and, in general, for environmental-friendly agriculture. Its variable wheelbase allows to seed the agricultural crops straight through the plastic layers with the same flexibility of seed drills working on bare soil. The perforating cones receive the seeds from the distributor and file them into the ground. The machine movements are completely regulated by electricity, so free from any type of mechanical transmission. The seeding modules are simply linked to a unique frame and they relate between each other through the CAN-BUS protocol, in order to respect the seeding phases. The seeds distributor is fixed to the single module and, in order to have a more precise and accurate control of the number of the seeds on the row, the rotor has been designed with the possibility of substitute the inserts to adapt to different crop types.
