I just bought an older late 80's / early 90's 930A. I'm very new to the mustang skidsteers and this one doesn't run (widow of the owner has no idea what is wrong with it) . I need to load this onto a trailer to move it. I'm wondering if I will need to unhook the drive chains or is there some other release to be able to winch it up onto a trailer or if it will be fine just to hook it up and pull it.
