I don't think the 3 point has down pressure, if its off the tractor hydraulics it is lift, hold, or float. Mine is a 41 and I hauled it away for a $200 trade, it would not fire at the time, but it was running a couple of weeks earlier, and it turned out to be points and condenser issue (not sure witch, I replaced both at the same time). They are an awesome farm tractor, I mow and bale 750 to 1000 bales per year with mine and green chop another 5 acres or so. Depends on your intended use, but the Farmall H is the only tractor model ever to out sell the Ford 8n. Parts are easy to find, and the tractor is easy to work on. I would trade my NAA for another Farmall as long as it had the 3 point hitch.
Good Luck!!!
