Just a note, BEFORE you spend the money on a B2601 have your dealer bring one out for you play with. Some on said the B2601 is a BX with a lift kit,, and they are pretty much spot on. I thought the B was going to be the end to my worries,,, I was wrong, I went off all the printed material, bad move. Now dont get me wrong the B is a nice LITTLE tractor and it functions well, however if I may offer some observations of my own.
1 the rear end is about the same as the BX and you sit higher,, I put 2 inch spacers on mine should have gone with 4, and while it has never tipped over it has come pretty close. And if you are going to be in the hills, it is something to think about.
2 The kitchen is not made for a big man or if you are a big ,crippled up some ,it is not an easy beast to get on and off, the lay out if great for someone young and maybe 5'9" and 140 pounds, but a big old fat man,, not so much.
3 Yes it will drag a 48 inch mower snow blade , blower and a ton of things. But I don't think you will be happy with it, looking at the size one would expect more from it. I don't know where you are building in the Wild and Wonderful but I would stay away from the R4 tires, someone figured skid steer tires on a little tractor was a good idea should be horse whipped. just MHO you understand. And on 50 acers while it might do well on the flats , if you plan on hauling fire wood out,,,,,,,,,
It is your money spend it wisely, all I am saying it dont just jump on it because it looks like it might to the job. If all you want to do is mow the lower field or clean stalls it will do fine for light stuff.
All I am telling you is what I have found with my B2601, I bought a bill of goods before I really dug in to it, and I want to save you the pain I have for it. My old BX 2360 has been through the wringer and still comes back for more, but in your case I would go for the bigger tractor , all you can afford. If I had known then, what I know now I would not have bought the 2601.
