Here's a pic of the hydro showing the internals.As you can see each side of the swash plate is mounted to a shaft with a roll pin.So if the roll pin breaks on the side of the netural linkage then it won't self center.Like Daniel mentioned  check to see if that both side move when you applied the forward/reversing pedal.That way it'll let you know if the roll pin is broken.Hope this helps.

Well guys under further investigation the shaft on both sides of the hydro move when the pedal is moved forward and back. Another thing I noticed(don't know if its related to this problem)was the parking brake won't hold. I'm guessing my brake band is probably wore out or needs adjusted up!? Has anyone tried ordering brake parts and hydro parts through Massey/Agco?

Hey luke its actually got 2 brake pucks.When I did mine I used the brake pucks out of a snowmobile.It was from a Polaris I believe.The diameter was the same,only I had to cut a flat spot in the one side to match the old one.The flat spot keeps the puck from turning.Another thing to look for is to make sure that the brake disc is floating on the shaft.It's designed to slide on the shaft as the pucks wear the disc moves.Also check to make sure that the small balls are still in and under the actuating lever.You can adjust the brakes by turning the nut in,its accessed thru a hole in the frame between the tire and frame on the left side.

 

The tractor not going into neutral could also be that the nut # 3 in the linkage picture could be missing or the bolt broken. Hope this gives you more to look at and check. Larry
