The TO55.T step seeder is designed for medium to small-scale productions and is equipped with a conveyor belt for containers. It is equipped with dibbling and a row by row seeding mechanism with a needle bar and disposes of 8 sets of needles of different diameters, which allow to process any variety of seeds. It features an interface for setting up seeding programmes and for eventually modifying its parameters also during operation. This seeder, which is easy to maintain and has quick retooling times, is particularly suitable for frequent seed/container changeovers and does not require a connection to compressed air.
