Lots of other people seem to drill OSR with subsoil type legs, mounted a seeder with 8 outlets over 3m on a tuplid vario (Like a sumo trio) to drill forage rape. Is there any need to use the legs or just run with the discs, light land, not made any mess with harvest yet, no excessive compaction. Will be grazed over winter and then into spring barley or maize. Will Using the legs just burn diesel and wear metal? Just drop legs in tramlines? Just wondering why so much is drilled on a subsoiler / shakerator type machine. We used to shakerate stubble and then combi drill, brilliant results but seemed overkill and expensive so trying a change
