So I am new to my ford 9n and need some info on the workings of my tractor. I got this 9n at a deal from a friend of a friend and was told everything worked liked new. It s been converted to 12v, had new tires, ran and drove in all gears perfect, and would lift me and a friend on the lift arms no problem. So I buy the thing and now that I have it here where I can hook the implements behind it, it will not lift them. I have a 5ft box blade, 4ft bush hog, a bottom plow and disc, which all of my grandfather used behind a 8n years ago. When I hook up the box blade for example, I hook up the bottom 2 lift arms it will lift fine, but once I hook up the top link it may get it off the ground a inch and just starts bouncing up and down. It does the same thing with the other implements also, so would this be a internal lift issue or is it something that could be fixed with a shorter or longer top link
