Any of the three you mentioned will work, and I'll add New Holland since that's what I own. I have a 115 HP New Holland that I use for what you say you do with one, and it has worked out fine. Pretty much any of them maintain their value well, especially JD. I'm old fashioned, and prefer the simple transmissions, instead of the electronic/hydraulic ones like I have on the NH. You should be able to get a very nice tractor for under 50K.
