I'm getting Dad's 1947 M back into use and having a real problem with the (1-row) cultivator. If I move the shank on the rear plows up high enough to get the front cultivators into the ground, the rig beam on the front rig falls off the lift pipe. Put the rear shanks down far enough to keep that from happening and the front plows won't touch the ground. It's like the lift pipes are too short, but they are the originals.
I plowed thousands of miles with one of these when I was kid, but I realize now that I just drove; Dad always set up the plows before he went to work. Ergo, I can't get the plows adjusted right and it's driving me nuts. Any thoughts?
