Okay, some confusion here. I thought you were using a 3PH back blade and had taken off the BH to attach it which is why I asked about the hose hook ups. But I see from this that the BH is still attatched and is functioning fine so scratch that theory.
Reading the WSM reveals that if resistance to both wheels is equal they will both spin at the same speed. If you put a load on one you could expect the other to turn faster, this is how it compensates for going around corners. When one tire encounters slippery conditions it spins and robs power from the other. This is where the dif lock comes in. It locks both wheels together so (hopefully) the other wheel can get a grip and move the tractor.

Well, I hope that's helpful, but as for a diagnosis I'm afraid I don't really have any ideas.
Good luck and keep us posted!
