Take a look at what direction the engine is spinning when it is cranking...from the PTO end of the engine (the front of the tractor), it should turn counter-clockwise. I bet somebody put a clockwise starter/generator on it.

The inner bearing race on the correct wheel bearings sticks out a bit so that when you tighten the bolt that holds it on, it preloads the bearings slightly. If you have the wrong bearings, wrong wheel, wrong washer, or any of the above really worn, what you are describing will happen. In one sentence, the wheels aren't supposed to have axial play on the spindle like that.
