Thanks for the advice. I guess I'm just a little concerned about finding parts with the age of the machine. The reason it was given to us is that someone put the wrong steering gearbox (I guess) in it and now it steers in the opposite direction that it should. i.e. When you steer right it turns left and vise versa. I'm hoping fixing that doesn't end up costing way more than the entire machine is worth. Otherwise it is not a bad little unit that fits our needs perfectly at school.
