The pit stop is the crucial factor
A manufacturer can promise a lot - but how do our machines prove themselves in daily use? Klaus Pentzlin, President of the Federal Association of Agricultural Contractors, has worked with a EDX 6000-T precision air seeder for years. His conclusion is simple: "As in Formula 1, the pit stop is the crucial factor." The EDX 6000 has to "refuel" much less often because of the huge tanks. The driver no longer has to open and refill the eight seed hoppers individually but can easily refill seed and fertiliser from the large big bag without a lengthy work interruption.
The fertiliser unit can cover almost 20 hectares and the central seed hopper holds enough seed for 17 to 20 hectares. Pentzlin is convinced: "The driver of the machine never wants to drive anything again other than a seed drill with a central seed hopper and a fertiliser hopper with sufficient capacity". It is important that the quantities of fertiliser and seed are more or less equal, especially on long fields.
Another plus point from the President's point of view: The depth control of the coulter units still works excellently even if the EDX 6000 is travelling very quickly. Only the seed placement accuracy in the row can occasionally become somewhat less precise at very high working speeds. In the end, however, a worse yield can never be attributed to the EDX.
Pentzlin is particularly impressed by the longevity of the technology. He bought the EDX 6000, built in 2010, as a nearly-new used machine in 2011. Since then it has sown an average of 710 ha/a of maize. "The EDX is the only machine which has drilled 790 hectares of maize in 13 working days this year without any significant problems – and that was in its 11th year of operation! The sowing performance depends on the driver, his hard work and organisational skills, of course, but also very much on the seed drill and its reliability. New fertiliser openers, seeding coulters and furrow formers are the only spare parts the EDX 6000 has needed over the years.
