If you aren't happy with it, take it back to the dealer. Tell them you want it fixed or replaced. You are the customer and it is their job to make you happy.
If you are asking, that is probably not the tractor I would have gone with. The EFI engines are made in China and the XT2 SLXs only have a Tuff Torq K46 differential in them. I know it is about $1000 more but if I was to buy a new Cub cadet I would minimally go with the XT2 GX54 D as it comes with a Kohler engine and a K62. Still I understand its not in everyone's budget, certainly not mine (my stuff is old and used), but I have hard time recommending a machine that I won't buy myself. That said there are a lot of people who are quite happy with their XT1s and XT2s, so it probably will be a good machine once the bugs are worked out and so long as you don't ask too much from it.
