Bolt "A" seen in this photo. The later models switched to a castle nut since it was a common failure point.

I will get a gauge ordered, I have been wanting one anyway. I will update you on pressures when I know. Thanks!

So, I can push the tractor forward and backwards in all 3 settings: slow, neutral, and Fast. I don't know if that will give any clue as to what's going wrong. I don't know enough about how these work to diagnose the problem.
