Don,
The fact that you asked the question on this site makes me think that you haven't explored much here,... click on "forum home" - scroll down to "attatchments" click and read /w3tcompact/icons/shocked.gif !!
There are tons of stuff scattered through all the threads on all the forums in this site. You will be reading for weeks, just to get a good idea of the breadth of topics on this site.
There are other tractor sites, but most here would probably agree that if you could pick only one, this is it! /w3tcompact/icons/laugh.gif
Speaking for myself, I hardly have time to read the posts I select to read (not all-of-them), and being retired, I have more time than many members.
I know I seldom visit any of the other sites anymore, ... though I know there is good info to be found there too /w3tcompact/icons/blush.gif .
Like any "study", benefitting from what's here will take a "time investment", ... but I'm sure it will be time"well-spent".
Happy hunting /w3tcompact/icons/smile.gif
