Okay, here’s the situation. 1957 Fordson. The way it works is that there is a control lever for the 3 point attachment that raises the back up and down. If you raise the back all the way up, you can use a valve right in front of the seat for the auxiliary hydraulics. In my case, that valve works the front loader. When I got the tractor, the front loader worked, but as time went on, I could raise the back and then switch to the front, but it wouldn’t work unless I wiggled the control lever. The shifter was leaking a little milky oil, so I changed the oil, and it was really white and chunky. Put an extra gallon in the hydraulics to compensate for the front loader. Last week the front loader stopped working altogether, so I got a pressure gauge to test the hose coming off the front/back switch. I disconnected the hose that leads to the front loader, raised the back, and switched the hydraulics to the front. Nothing was coming out until I wiggled the control lever, and then I got a stream of oil at about 320 psi, which is about right. So I worked with the front loader for about an hour, shut it down, and when I came back, I couldn’t get the front loader to work at all. Tried several times, but no go. The back raises and lowers no problem, but the switch to the front loader doesn’t appear to work at all. What do you think?
