I guess I should have clarified! The swales that were the subject of the original discussion are already done. I did it with the rear blade and manually adjusted as required. This went very quickly. Now I will be grading around 2 acres, plus finishing and maintaining a 450' drive. I have enough time in with the rear blade to know I want tilt for sure, and perhaps a hydraulic tip link at some point. All options are too expensive right now. It seems that an open center control off the PB and some cylinders from CCM is the cheapest option.
