In 1999, Väderstad initiated the tillage practise minimum tillage, aimed at creating stale seedbeds at 5cm working depth, with the disc cultivator Carrier. Due to the shape of the standard disc, this type of concept however lacks the ability for a full cut-out at working depths above 5cm. Ultra-shallow tillage is a further development of minimum tillage.
Looking at the market, several tine solutions are available. These have the benefit of distributing straw, but they will not cope with high amounts of residues and they are limited in speed. In 2014, Väderstad introduced the ultra-shallow front tool CrossCutter Knife, followed by the new generation ultra-shallow disc in 2017 - the CrossCutter Disc.
