We were thinking of the same, had solitare 8 with power harrow but lost most of heavy ground drilling and we are light land. Helidor was something like 15K, so we bought a Horsch 3m Pronto DC instead, brilliant drill.
Surely someone or a company is out there that could help us set up a new assurance scheme for combinable crops. Is there enough farmers that would back a new scheme financially? Just thinking out loud.
