Welcome. As you can see, you will get lots of good and different advice here.
My situation is not a lot unlike yours, although I have a bit more ground. We have a 10 stall horse barn. I really think, unless your barn is set up a lot different than mine, there isn't a tractor that will work in the stalls AND be big enough for the other work you want it to do. The paddocks, yes, but not the stalls. Stalls, set up like mine anyway, are skid steer territory. Fortunately, I have a 20 year old step daughter who does the skid steer duties, by hand. Good for her character. /forums/images/graemlins/grin.gif
Among other things, I was looking at the Kubota
BX1830 and
BX2230. Now we all know tractor dealers never lie. I was told by my dealer that the 22 holds its resale value better than the 18. Although I really needed a bigger tractor than either one, money was a definite issue. I bought the
BX2230 with MMM, FEL and 4" rotary mower. It will just have to do. Life, and money, force all kinds of compromises.
In a more nearly perfect world, where I have a whole bunch more money and am taller, I would have bought two tractors. One for the lawn mowing, which is the main job of my BX, and a larger tractor, with a larger FEL and RM, for maintaining the pastures and woods.
