Agri Series

More information

The Vredo Agri Series is famous in the global agricultural sector. This machine is a direct descendant of the very first overseeder, built in 1976! In the course of years there have been a great number of developments and improvements  on the machine, including a highly accurate mechanical seed distribution system and progressive spring guards. This robust but precise machine is very suitable for dairy farmers and agricultural contractors, to provide the fields with lush grass in the spring, after the first cut or in the autumn.

Models

The Vredo Agri Series is available in two models:

  1. DZ 225.07.5, with a working width of 2.5 meter
  2. DZ 229.07.5, with a working width of 2.9 meter

These overseeding machines can be equipped with a smooth roller or a special packer ring roller, for following undulations on rough, stony surfaces. The two sections pivot and every pair of discs is separately suspended, which results in the machine being able to follow undulating land accurately.

Continuous seed distribution

Agitator and seed hopper

Seed distribution system with hectare counter

The machine is equipped with a mechanical seed distribution. The mechanical seed distribution is continuously adjustable from 3 to 210 kg per hectare. For very small (clover) or very large (grain, barley) seeds and quantities, special cam wheels are available. The seed gets equally spread over the seed-elements and placed in between the discs. Due to this, all the seed gets into the ground. The seed hopper can be filled even more easy via a (optional) standing platform.

The capacity of the seed hopper is related to the working width of the machine:

  • The 2.5 meter machine has a seed hopper with a capacity of 250 liter.
  • The 2.9 meter machine has a seed hopper with a capacity of 290 liter.  


Double discs

Vredo double discs

Overseeding is only useful if the seed is sown directly into the soil. The Agri Series is therefore also equipped with the Vredo-Double-Disc-System. Only that system guides all the seed into the narrow slot. Every machine is equipped with a compaction roller, this guarantees a quick germination and deep rooting of the injected seed. The pairs of discs have a row distance of 7.5 cm and are sprung separately, which results in a complete, close and healthy sward without weed. Research has confirmed that the Vredo Overseeding System generates a germination rate of 96%. Because the seeding depth is precisely adjustable from 0 to 25 mm, this high result can be achieved.



VREDO overseeding principle

Double discs with turf guard close up

  • Double V-shaped discs which make a small cut in the soil.
  • Seed is placed in between the discs.
  • The slit is closed by the compaction roller.
  • Optimal situation for germination: The seed is in contact with the soil and gets the optimum amount of light and air.
  • The seed is protected against weather influences such as frost and birds.

The combination of Double Discs and the spring and turf guard ensures an optimal seeding depth which means the most efficient usage of expensive seed.
