Vaderstad's shot on target

Today's agricultural market boasts a variety of seeders for row crops. Despite the different design solutions, they share the same type of broadcast seeding technique. The seeds are broadcast from a mechanical or vacuum batcher by gravity and drop into soil. Moving at a high speed, the seeds crash against the seed chute walls which affects the seeding precision.

The Tempo seeder from Sweden's Vaderstad uses a completely new technique of seed embedding, known as Power Shoot. Under high pressure, a seed is shot at a speed of 40 metres per second from a seed chute, like from a pneumatic gun. This minimises the vibration impact and assures an exclusive seeding precision in spite of the high speed and soil surface irregularities. The seeding speed of Tempo, 12 to 15 and even 20 km/h, doesn't compare with the traditional 8 km/h. The soft compacting wheel instantly compacts the seeds, thus eliminating "the hopping effect."
The Tempo was first displayed at the Agritechnica 2011 exhibition in November of this year. Customers of AgroCentre were among the first to see this novelty of the world's agricultural engineering when they visited the stand of Vaderstad. The presentation was conducted by Christer Stark, chief developing engineer and chairman of the company's board of directors. 
“We've been developing this seeder for over 15 years during which time we've carried out a lot of research to find out how the seed lies down on the seeding bed and what should be done to avoid the adverse impact of speed on embedding precision. The final product is the Tempo system now before you,” says Christer Stark. “The seeder is presently undergoing the last tests. The results speak for themselves. For instance, in Ukraine they have sown 130 hectares in one day using the eight-row Tempo system. This is comparable to the traditional twelve-row machine. One seeder has already been sold to Russia.”
Christer Stark pointed out that Vaderstad now manufactures two models, Tempo F6 (six-row type) and F8 (eight-row type) for seeding maize and sunflower. However, it also plans to start manufacturing a twelve-row type, specifically for the vast fields of Russia.
