Franck Chevallier has developed a open source subsoiler which is designed to be able to be built by local metal workers using readily available materials. In 2016 Regrarians' Darren J. Doherty instigated the formation of a working group to develop formal CAD plans to support Franck's effort and to further develop the #KeylineSuperPlow concept we've been working on since 2006/7.
Luke Hallam came to the fore with the development of many CAD concept models and these are manifested in this set of working drawings. Luke and Franck have done a great service in doing this fantastic and unpaid work!
The best feature of Franck's design is the very unique and effective shank break out mechanism. Its superior to any other system commercially available, with the exception of the very expensive hydraulic break out systems.
The next step is to have the #KeylineSuperPlow concept go through a similar CAD process and this is now underway.
