Hello and welcome to Just Answer,
Lets work on the brake problem first. See attached picture. These are the parts they are referring to. The nut is shown as item#9.
Sorry about that. Your original question stated you have a 130, not a 133. Here is the correct one. Let me know if this looks like your transmission. The brakes on that unit are adjusted by tightening the nut labeled #13.
See attached picture. Is this the item 16 you are referring to?
You will likely need to remove the deck to make it easier to get at.
