A friend of mine has a MTA that has always ran and operated good. Last week he loaded it up to take to a show and when he went to unload it it would not start unless the clutch was depress and when started it will not move and dies when the clutch is released. I don't know much about these but it sounds like it is stuck between gears a broken gear tooth in the gears. He thinks it might be the TA or the PTO. He has the top of the transmission off and says everything looks OK but he isn't sure what to look for. I am going over this weekend to look at it and if you have any pointers as to what to look for I would appreciate hearing them
