Again, I'm so happy to have this new "tools" forum! This is another thread that I never saw until now...
The first post, Frank's tractor, I would pretty much kill for; but in my simpler world my two favorite tools (at the moment, at least, are a hand hoe similar to this -- which I don't remember where I got (maybe A.M. Leonard, I think)
The other, which probably should be the first, has seriously been a godsend to me because my hips and knees apparently are no longer in mint condition... this came from Gardener's Supply
And I should also mention my spading fork, which I requested for my birthday present a number of years ago !
Oh, and our well-worn rototiller, which was the first thing we bought together about 27 years ago...
(I mean, really -- who can pick just one favorite??)
