Three-link harvesting with the application of grain transfer trailers is the main system used for harvesting in countries with developed agriculture. The practice showed that the application of grain transfer trailers at harvesting increases the productivity of harvesting machinery by 35% at an average rate.

Grain transfer trailers are applied in the process of seeding for the quick loading of seeders. The practice showed that when using grain transfer trailers, the average productivity growth for seed drills is 30%.

The essence of this technology is the air tightness of storage. After a bag is closed, the special three layer polyethylene will preserve grain from the air, ultraviolet, and moisture. In the process of natural breathing of grain and microorganisms the mass fraction of oxygen is significantly reduced while the fraction of carbon dioxide is increased

In most cases, the technology of loading into railroad cars supposes elevators as stationary transloading points. Having its own elevator is one thing, but shipments through «other» elevators owned by third-party companies is quite the opposite.
