The left lever standing behind and looking in direction plow is going is the depth lever and as low as that lever can be put is transport position to raise plow to full clearance, to go deeper you raise the lever but you will never need to raise it to full height, stop about 6 notches from full height and try and then adjust lever down if still to deep or up if too shallow. The lever on the right hand side is the side tilt lever to level the plow while working, in transport also put that lever full down. When starting first furrow raise it close to all the way up to compensate for the furrow tire on top of land instead of furrow, now on second round put that lever about to the bottom and when you get going adjust for tilt so you are plowing level and smooth. That front bottomset too deep will make the plow want to run sideways to the left at the back. Your drawbar is i bit high for that plow as the tractors it was designed for the drawbar was about 11" from ground so you may have to adjust the side plates the drawbar is attached to. Then that adjustment on the rod that goes to the frame and drawbar is so you can lift the plow out of the ground at end of furrow, without it you could not lift the back end of plow, Now to get started to adjust that when you get the plow in the ground take that rod off and pull for a ways, possibly 50' and the plow should level itself out front to back, then put that rod back on si it is just between trying to lift the babk end of plow and pushing down on the back end, the pins should go in easy, after you get it going you might have to make a final adjustment and it should raise the rear enough for transport but when in the ground that wheel should be making an even imprint in bottom of furrow. Just try to go about 50' each time you make an adjustment. For use with am M it should be either a 14" or 16" plow as a 12" and H would be correct size. Is your plow an early version with the open clutch or the later version with the oil encased clutch and was it factory rubber or steel and if was steel and cut down to rubber what size tires do you have on it. Factory rubber on land wheel would have been either a 6:00 X 20 or a 21" tire with furrow wheel a 5:50 or 6:00 16" tire, if converted with 16" on land wheel then put a 7:50 x 16" tire on there as the 6:00 would not let it level out. The lighter weight No. 52 plow used both the same size tires and that is what I grew up with. A 14" plow should cut 7" deep, a 16" will work at 7" but designed for 8".
