Seeding and fertilization

The best possible growing conditions are determined by a properly prepared seedbed. There are different sowing machines, based on the type of seed, type of material and environmental conditions, and they are specially different due to the dosing system (mechanical or differential air pressure).

The opening of the furrow, the control of the depth of the seed and the covering of the seed are carried out in different stages and by different equipment:

 

  • Furrow opener disc;
  • Level wheel;
  • Seed introduction wheel;
  • Seed bed closing wheel.

 

Loads type and Bearing Choice

Loads type and Bearing Choice

The main type of product used is the Agri Hub, a complete bearing assembly, lubricated and protected for life from contaminants, however different bearing types are also used, such as special bearings for supports (with round or square bore) and double row angular contact ball bearings (DRACBB).

Seals resistant to dust and mud infiltration

Seals resistant to dust and mud infiltration

Specific tests infiltration of dust and mud allow to optimize the design of the sealing system, respectively realized by the rubber seals (6-7 lips) and by the grooves on the rings (different shapes and complexity of execution).

Easily assembly

Easily assembly

The Agri Hub disc holder is available with 4, 5 or 6 fixing holes, threaded or through, and different threads and thread pitches of the central pin, making it adaptable to many different discs.
