I love the tractor. I have not had any breakdowns so far and it has proven to be very reliable. Only around 360 hours on it so far, but I think that is still pretty good, especially since it has been with me for 4 seasons and been asked to do a lot.
The only advice I can give is that if you plan to use it to blow snow, get a cab. You will not regret the extra cost.
