1971 Gravely super convertible.
I've got both the plow and bush hog attachments for it. When I got it from the wifes grandpa in 1995, it had less than an hours use on it. He bought it, tested it at his house one time, then it sat in his garage till I saw it. I used it to clear nearly two acres of overgrowth at my house, and another acre at some property down by the river. I bought the plow attachment for it when we moved in to our current house, but pussed out and bought a plow for the tractor the next year.
I still use it a couple times a year to cut down the stuff I can't get to on the tractor that I just let grow most of the season.
