Looks pretty good Rob. Like RonM stated, most plots in the north/northeast don`t plant brassicas until late July or the first part of August.
What brand/model disc is that? I just turned 4 acres of virgin ground on thursday with a Summit Plot Mule and I had no problem turning ground right down to the axles on the discs....maybe 6". You may be going deeper than it apprears, try to drag/harrow what you have now to remove most of that chopped up cover.
Good luck....
