I recently bought a '62 IH 404. The hydraulics (steering and 3 pt. lift) seemed a little slow to respond after starting, but then worked fine. The day after I used the tractor for the first time (light brush-hogging), the hydraulics seemed to respond even slower than originally, but then again, once working, worked fine. I assumed it needed a filter change so thats what I did. Now I have NO hydraulics! I was told that the pump probably lost its prime and to drive the front end into a ditch. This had no effect. Does anyone have any ideas? Is there a screen or anything between the trans and the hydraulic system that could have become clogged and not allow fluid back to the pump? When I check the hydraulic level in the rear, it's now overfilled which makes it seem that it's not allowing it to circulate back to the pump. Any help would be GREATLY appreciated!!!!!
