How a TT is built

Most things are built that way. Sorry to say. There is a large agriculture tractor manufacture near me. I know someone that works there. She works on the line and she tells me that the employees are told to just put the tractor together and get it out the door. Even though they know they are not putting it together right and that there are defects. Once the tractor get to the dealer the dealers mechanics take it apart and fix the assembly defects. She can't figure out how this makes any since but, that's just the way it done.
