GREETINGS!! ???Now that you have clarified more your definition of a "metal frame", I'm not really sure that I have it! As I look behind the drive wheels, I see what looks like a metal frame. It seems to me that what is metal and what may be plastic look so much alike that it is difficult to determine without actually taking the thing apart , which I choose not to do at this time!
THANX!!
