Adding a hydraulic circuit to a 300U

ChrisNH · Jun 27, 2010

I have a 55 IH300U that came stock with one hydra-touch circuit which lifts the fast-hitch. Wanting to add another, I picked up a hydra-touch control valve but the block underneath the valves (check valve I think) has the hose ports right up against the tractor body so close it won't bolt on. I am trying to put it on the empty valve port on the right hand of the driver's seat. Is there a spacer port or maybe a different check valve with hose ports on the bottom I need? I would bolt it onto the existing valve, but it has a hard hydraulic line running from it to another block between it and the tractor. Is there a way I can add it there?

You only need the check valve for the fast hitch. How would the clearance be without it in the front position?

OK, so the small block that bolts beneath the
handle valve isn't a check valve. You know what a
standard single-circuit Hydra-touch mounted on the
tractor looks like - I basically have the outside
portion of that with the block below it that has
the hose ports coming out the side. The problem
is, that block was only designed to work with
something else between the main block and tractor
- there just isn't any room with the hoses coming
out toward the tractor. The guy who sold me the
hydra-touch assembly said it would work fine.....
I didn't think about the clearance issue. I guess
I need whatever is normally on that extra front
port that is capped on a single-circuit tractor.

In pictures I have seen with 3 valves, 2 were in the front and one in the back. I added a second valve on to my tractor and put it in the front section.If you have fenders I don't think you can go 2 wide in the back.

So how did you add it to the front section? That's what I'm trying to do but the hose connector ports are right up against the tractor body.

Thanks Club149 - based on your comment and checking out the parts diagrams on the Case site, item 295, I see that if the check valve is removed, the hoses can simply be screwed directly into the control valve assembly where the check valve once was. Clearance is now no problem and I won't have to be getting on and off the tractor to move the snow blade this winter! Many thanks.

I should have added a photo of what mine looks like. Glad to see you got it solved.
