Looking to add a loader to the 300U for LIGHT moving of LIGHT material (not sand, rock, etc) but I don't have a manual yet on this one and it occurred to me that there is likely a limit to how many toys I can have on one tractor. It already has fast hitch and dual remotes. Am I going to have space issues adding controls valves for the loader?

Why not use the tractor remotes for the loader? What other controls do you need?
 
One 'remote controlls the FH.The other may run
another implement.The 300 may not have enough
capasity for a loader.JMHO
 
No. You can put the valve directly on the loader.Just use a 'stand' to put the valve in a convienient location.
 
I should clarify a couple of things here. One is that the remotes are needed. I have a variety of implements that could/would end up behind the tractor while the loader is on it. Loader would not be in use at that time, granted, but I would still need control of it. The other thing is that this loader would be the Mccormick loader made for the tractor and not something aftermarket. If memory serves me it is controlled by dual valves that mount on the side of the seat (I could be wrong). So I would end up with a single valve that controls the remotes and another for the FH and then dual valves for the loader (if I am right about that). I have seen 300U's operate these loaders just fine. Just worried about can I have that many valves next to the seat or will I have to rig up a stand as mentioned below. Thanks! Hope this clarifies!
 
I have a 300 Utility with a U34 factory loader. Mine also has 3 valves, the two front ones are for the loader and the rear one is for the fast-hitch. The only problem would be if you would need a 4th one for an implement when the loader is on. Al

It does get to be a bit complicated doesn't it? Having said that, I'll also say that nothing is impossible if you want it bad enough.

Does the tractor have fenders? Maybe you could mount the loader controls on the fender?

Might need to "TEE" into the main hydraulic supply BEFORE it goes into the existing remotes?
 
The problem you will find is that the hydraulic system doesn't have a big enough reservior to power the loader. I have a 33 (?) loader on my Farmall 350. Only if I have the tank overfull will it lift to full height - then its empty.

The McCormick #30 and #31 loaders have reservoirs built into the front of the cylinders. As the loader is lifted, the oil in the cylinder reservoir is pushed into the tractor hydraulic reservoir, and as the loader is lowered back down, the extra oil is pushed back into the cylinder reservoir.

Does the #33 not have that feature?
 
Gonna have to figure out something, that's for sure. Maybe when I actually get a chance to see how these valves are tied into the rest of the system it will come to me. Just plumbing when you get down to it!
 
Rusty, I don't think the U34 loader on a 300 Utility has that feature either as mine only has single acting cylinders with one hose. I never had a problem with the loader not lifting to full height. But I do remember a friend who had an IH loader on a 300 Row Crop and that wouldn't lift all the way up unless he over filled the resevior. Al
 
On the 300 & 400 tractor there is three valves stacked togather, only thing bothering is the fenders, you could move that out.
 
The key to adding separate remotes for the loader is to either:

1. Redirect the oil going IN to the factory valve stack to the loader's controls, then back to the valve stack.

OR

2. Redirect the oil coming OUT of the factory valve stack to the loader's controls, then back into the tractor's reservoir.

I know it's possible on a 300U, but I don't know how it's done.

The pump should be 12GPM and 1250PSI. That's adequate for a loader

Does the tractor have good tight powerful power steering?
 
If I was using other implements, I would take the loader off. You said you were using the origional mccormick loader which is a u-34. It only takes 5 minutes to remove and 10 to install. It sounds like you have the correct valves for the loader; there should be 3 hose connects on r/s and 1 on l/s. I just made hoses to run from the outlets/connections to the rear of tractor to hook to my implements. The u-34 in my opinion, was one of the first quick attatch loaders. Mark
