So, like I said they isolated the problem to the control valve for the 3ph. My dealer told me he had a hard time swallowing $700+ for a new valve without knowing WHY that one wasn't working properly. He disassembled it (the fella I'm speaking of is the one who owns the dealership. He tore my tractor down himself, I love that place) and found that the spring for the check valve was inserted backwards. I wish I had the picture, but basically the spring had a conical shape, and the "big end" was turned toward the steel ball. So the ball was inside the spring. It didn't take much flow to push the ball sealing the opening and closing the check valve. He turned the spring around so the small end was facing the ball and VIOLA! Works perfectly.
