Urbinati S.r.l.

- Beta Seeder



The drum seeding line Sigma can reach a production up to 1800 trays/hour, thanks to the transversal positioning of the trays. The empty stack feeding belt, included in the standard composition, enables to reduce the maintenance of the machine.

  • The trays advance one next the other on the trayfiller belt, ensuring the maximum filling uniformity in every cell, also in those along the edge of the tray.
  • The filling can be adjusted with one single handle and enables a variable filling with soft, medium or high density.
  • The brushing group perfectly cleans the trays from the exceeding soil, which is completely recycled without any wasting.
  • The driven dibbler ensures a centered positioning in the cell and a perfectly regular shape of the hole.
  • The engineering solutions of the seeding group produce a perfect singularisation with both small and big seeds. A second seeding drum can be added for multiseeding or chemical grains dispensing.
  • Changing the seeds or the trays is faster, thanks to the fast adjustments and the drums changing without any tool.
  • The drum coverer for vermiculite or other grains performs a great uniformity and enables to choose the working width and the quantity of product distributed, to reduce any wasting.
  • Each component of the machine is designed to improve the work of operators, thanks to fast adjustments, low noise, high quality and strong building to reduce maintenance.
