[AT] 800 Ford tractor 3 point

[Aaron Dickinson]

Carl, 

If your H is a Farmall H and you are using the belly pump and controls, the reservoir is small, the international 30 and 31 power loaders used long cylinders which are ported on both ends and look like two way cylinders, but are plumbed to use the top part of the cylinders as reservoirs so that there would be enough oil to raise the loader. Also there is a delay/priority valve between the two front outlets and the rear outlet to aid in raising and lowering cultivators. As you approach the end of the field cultivating and pull the lever to raise them, the front gangs raise first, once fully raised the rear gangs raise. Once you make your turn and head back down the rows, push the lever forward and the front gangs lower, then the rear. International made a remote cylinder control valve that mounted on the fill neck and plumbed to one of the front ports, it allowed the use of a remote two-way cylinder.

Dean, 

Not familiar with the 800, so not sure if this applies to you or not. On my H I have both front loader and 3pt. When I pull back on the lever the loader will raise all the way to it’s max height and the 3pt will rise maybe an inch and that’s all. It’s a matter of pushing all the fluid into the loader cylinders and then there not being enough for the 3pt. In order to use the 3pt during the summer when I don’t need to use the loader, I simply run a chain from both loader arms under the front frame to keep the loader from rising too high, then the 3pt can rise to it’s max height. I shouldn’t have to do that, but I think there is an issue with my pump valves that won’t let me control where the oil goes. There’s just not enough fluid volume to use both sets of cylinders at the same time. I’ve got an auxiliary tank and a set of control valves that I plan to plumb in so that I can increase the fluid quantity and have independent cylinder controls, but just haven’t gotten around to it yet.

I would appreciate some help from you Ford tractor experts.  Have successfully sold the Ford Jubilee at a good price but not the boom pole that was attached to the 3 point. We need that for lift other stuff in the future. So we attached it to the 3 point on a Ford 800 only to find out the 3 point isn’t working at all. The dipstick shows being full of hydraulic oil. The next step is to try to bleed system at the pump up font.   Assuming we are successful at that and it still doesn’t work what would you recommend for further diagnostic checks?  The 3 Son’s have no knowledge of tractors at all and I have very limited knowledge regarding the N Series on up.  I’m trying to help since they are allowing me shop space free of charge.
