It looks like that tractor is almost under utilized in its current configuration.... looks like a very tough tractor. I'm guessing in modern terms it would have cost you somewhere in the $9k range for an equivalent. That's a real bargain.
Honestly, it's probably going to be underutilized with me too. But I'm a firm believer in buying bigger because when you do need to do something it's capable. Once fall hits and I'm done mowing, the deck will come off it will be used to drive down a path into the woods where my firewood is stored in giant galvanized culverts. I'll use it for snow removal If Ever I come across a blower. And going to keep my eyes out for good deal on a tiller too.
But for now I have an Ariens st350 walk behind blower I inherited from my grandpa. Couple years ago somebody threw an old phone book in my driveway, well it snowed on top of it and I didn't see it. That st350 chewed up and spit that phone book out on the side of my driveway lol.
