Bird, yes, I almost forgot about that. There's a 'Board FAQ'...Frequently Asked Questions around using TBN, but not a "Tractor FAQ" If there is one, please let me know.
Here are a few of types of Frequently Asked Questions specific to tractors that might be asked.
What's the difference between hydrostatic/shuttleshift/gear transmission?
How big does my engine need to be to run this PTO generator?
What's the difference between synthetic and regular oil?
How does power beyond work?
Where can I find parts for a xxxx in my area?
Who makes which CUT?
And many, many more.
The point, though, is that a complete novice may not even know enough of the specific vocabulary to do the right searches. Also, interactive part of a forum is lost if you find a thread that's a few years old, but have reservations about dredging up an old thread to ask some questions on it.
And besides, sometimes it's fun to answer a question that's been asked a million times before. Using the search function to try to find that one thread that you remember from last year that was almost the exact same question makes it even better.
