We have 2 tractors here. A ford 9n, it's small and light enough not tear up the ground. We use it for lighter duty chores. Mowing, or pulling a trailer full of gear.
The second is a 45 hp diesel. If I could only have one it would be the diesel. It has enough weight to skid logs or hook up the backhoe attachment. But could still be used for lighter tasks.
I made a misstep when I bought it years ago. No front end loader. I had never had one and at the time did not realize just what a work saver they could be. Still getting by with a boom pole and back bucket is not that bad just a lot slower. (Looking for one now though we want to build hugelbeds!)
As for attachments you might try auctions, both online and in person. We picked up a model 48 john deere backhoe attachment for $1500, which is cheap for our area. I am always seeing mowers and other equipment at them, often at low prices.
