In my search for coulters for my Massey #62 I came across one of the old Ferguson disk plows. This one seems to be complete, even the kick stand is still there. This one has the straight tube frame. I know it depends on how bad the blades are worn down but if they are close to their original diameter, how deep will they dig? Are the comparable to a 14" or 16" moldboard plow? Do they pull any easier than a moldboard plow? Lastly, how do they fare on hillsides? Which I know there isn"t many one way plows that do great on hill sides but I didn"t know if the disk plows were any worse or better because I have no experience using one of these. I am seriously considering buying this plow though. Sorry for so many questions I"m just trying to make an educated decision. Thank you for all your help.
