I saw one of these up close and in action at last months field day. Of all the tedders there I thought this one and the Vermeer were the best by far. Really, if you look at them side by side all tedders are just alike. I think it would be difficult to differentiate yourself from the pack. To me, Vicon and Vermeer accomplished that. As for the Vicon I think it was well thought out...one set of remotes for arms and tilt, heavily built arms and integral hitch pin. It seems there were at least a couple more features that struck me as above/beyond but I cant recall this right now (sorry!). If I couldnt get a Vermeer Id buy a Vicon.

Gerry,
Sorry I misread your post and did a 'sales pitch'...didnt see the word 'repair'. Cant help w/ the repair ques. much. What bits are you thinking about? The Fanex looked pretty straight forward and not hugely diff from any other tedder.
