On some of the older ones like that, you had to move the lever by the three point hitch controls to "constant pumping" or you did not have aux hydraulics. Not sure if that is the case with your tractor but it might be worth looking at.Have a Forf 800. Never have used the aux hydraulics, ie, the couplers. Hooked up a single acting cylinder, one line, and i cant get it to move. I should be able to use a single acting cylinder, shouldn't I? How can I check this out?
Ok, the lever did the trick. However, when I raise the implement up (pressurize the hydrogen cylinder) it slowly drops back down. I guess it could be either the cylinder or the tractor valve leaking. I'll try to find another cylinder totry.
