My experience has inclined me to buy the smallest possible tractor and weight it up as much as possible. Part of that experience goes back 18 years, when on our property in southern Indiana we had a pond dug. Had a great old excavator named Walt Taylor dig it, mostly with his (little) dozer. He noticed I had a Kubota, the 13hp late 70s model I'd inherited from my father, and to my surprise was a real fan. He told me it was his brother who advertised in the paper that he tilled gardens with a "Kubota tractor and tiller."
Well, the pond needed a clay sealer that needed to be tilled in, so we hired Walt's brother. He arrived towing his outfit, big HD pickup and trailer and a little B series that was about 24 hp. He tilled the heck out of that pond bottom and it stopped the leak.
When he came back to be paid he was towing his rig again but had a bushhog on the tractor, said he was on his way to cut for someone. It was at least a five-footer--and maybe a 6. He said the dealer told him it was too big but the tractor would handle it. He said he worked his tractor hard and used straight 50 weight oil. He also had cut the roll bar off because it hit limbs when bushhogging, which I thought was insane and still do. He had made a little shelf out of the rollbar at the height of the seat back.
I wondered why he didn't get a larger tractor. He said he didn't want to have to have brakes on his trailer and a bigger tractor would obligate him legally to do so because he'd go over whatever the cutoff was. I later got a 16 foot trailer with electric brakes and it was no big deal. I wonder if he didn't consider electric brakes BRAKES and was talking about REAL surge brakes?
Anyway, I think of those brothers sometimes. Nice guys, good equipment operators, Bota fans, original characters. They gave me a lot of faith in small tractors to do big work, with care. At least one old feller and his little bota made a big dent in Hoosier weeds and dirt for a while.
Small is beautiful. I remind myself that because I am shopping for a tractor and tend to want just a little bigger. I know a BX is what I probably should get but keep looking at 2601. It can be true what folks on these forums always say, that your work will evolve if you have the capacity for that. But I also think it is folly to size your tractor for 5% (or less) of its use.
I know a guy who got a 30 hp+ Kubota for his few acres, a machine fit for 40 acres in the old days. It is beautifully equipped and just sits in his garage. It is too big to maneuver with a mower in his spaces. He uses it in winter for snow removal, and it's wonderful for that. I'd rather have a tractor that was optimum all year and fair at snow removal.
