Yes, tractors make excellent pets!
Just keep in mind that they are bred for pure aesthetics, and not for work! Even if your tractor insists on helping you in wichever way it can, don't allow it, as they are very frail machines!
Your tractor may seem unhappy, if you treat him/her like this, but remember, this is the proper way to do it, and it's just part of their temprament!
