I bought a 2008 New Holland TT75A with a Bush Hog 3545 loader. The tractor ran great and loader worked fine until the first hard freeze. Must have been water in the loader valve as it cracked the housing. I replaced the valve with a dual handled cheaper one which does not have a power beyond port. The original valve supplied oil to the rear of the tractor (3 point hitch) via the power beyond port. I'm not sure this was correct and want to know can I put a tee in the pressure side of the hydraulic pump and feed both the rear of the tractor and the loader? Will this work or will the oil just flow to the path of least resistance? I'm scratching my head and need some help on this. Right now, I'm just supplying the loader valve as there is no power beyond to hook up for the rear.

Your original valve was installed correctly and yes, the flow will follow the path of least resistance, that's why you can't tee pressure lines for feed multiple valves in an open center system.
You'll need to either get another valve and the correct power beyond sleeve (those are specific to the valve make and model and not generic) or maybe your new valve has a power beyond port and just needs the sleeve but you maybe you haven't noticed.
If you can post a picture of the valve we can try to figure that out.
