1952 Ford 8N Tractor. This is my 1st Tractor so please pardon my ignorance of terms, etc... I know I'll make many mistakes. Here's the Deal: - There's a rather large, longer 'throw' handle w/ a gray knob to the right of my right buttcheek that makes the rear thingy go Up or Down. I believe this only goes up and down when I'm in Neutral with foot off clutch (or some other combination I'm forgetting -- neverthess, I can get it to work at some state) - It'll make the rear thingy up all the way and all the way down just fine, as long as I'm operating the handle. - If I pull the handle Up so it goes all the way Up, then level the handle to "hold" it in the Up position (hand off handle now) , it'll bleed down rather quickly (say 20-40 seconds w/ no load). Note: It appears that there could've once been an 'operating range fence' for that handle to 'work' in, but it seems if there was once a stop mechanism there, its gone now. I see a wingnut thingy on outboard side, but the handle can, and does, move beyond any kind of a 'fence'. I need to move the handle out in this region to get it to go up and down. - I yesterday hooked up the [rather heavy] plow to try it out for the first time. I attached it so that in the 'down-most' position, the blade was barely ground level. (I did this because I was unsure about this 'bleed-down' of the lift mechanism and didn't want this monster dragging on the ground too much). - I could get the thing to go all the way UP by pulling back on that big lever, then putting lever to a 'hold' state, then goto clutch... but by the time I'd get it into gear and start do de-clutch, the darn thing would be back down on the ground. * Am I crazy, and this lift is only a 'temp hold' feature?? It can't be, right? It must be broken, yes? (note again, 1st tractor ever). I'd expect I can put the rear lift at ANY position I desire (w/in range), and it should hold for a significant amount of time (hours before a bleed-down). * If so, I'd expect that I can 'force' any implement down and below grade level, right? (I'd assume to do this by installing the implement/blade at a 'mid' position of the Lift Mechanism, yes? Then, once moving, drop the Lift Mechanism down forcing the blade below grade. Thank you for any insights and suggestions you may have for me. I appreciate all input!!! andrew in almont.
