I had a 4310. It is a good machine that I think you would like better than the other machines you mention in comparison. I found my 4310 short on engine power in the e hydro configuration, but I live in the mountains and had very steep hills to climb. In TX, even in the Hill Country, your hills are not that steep, so a 4310 would do fine there. It is reliable workhorse of a tractor that can go and go for many years. The engine is a really high quality powerplant that is not overly strained in this application.
