I'll skip over any tractor brand names to avoid the "noise" that this might add to the thread... The thing that has always driven me to one of the more common brand name tractors is this. I buy tools to work for me. And when I need to get something done I expect the tool to perform. My tractor is a tool, and it is important to me that it work properly every time I need it.
If you consider the volume of the most common name-brand tractors, you see (relatively speaking) a fairly small volume of weird or catastrophic failures posted on here. And if you consider the relatively small number of lower cost brand X tractors sold, you see (relatively speaking) a fairly high volume of weird or catastrophic failures mentioned. Another factor to consider is resale value and depreciation.
I'm not "right" for deciding to pay the extra dollars for a common brand-name tractor. It's just what works best for me. I can fix many things if I put my mind to it, but I choose to minimize that likelihood because i enjoy using my tractor more than fixing my tractor. For others, the chance to save a few thousand dollars trumps the possible inconvenience from a weird or catastrophic failure and it's what works best for them. I say, you just figure out which of these two profiles fits you best and go with that. Good luck with your purchase and don't forget the pictures after the purchase.
