Update: I called the dealer last week and they still haven't worked on my tractor. Their service manager said that they would get to it this past week, but alas, still no word from them. I'm not complaining though, as I have the 3550 to put hours on! I do like the size of the tractor as well as the loader control, but I do not like the HST. I prefer to push on the gas pedal and the engine to rev instead of having to run the hand throttle up, but I'm not going to complain about a loaner tractor. I will hopefully update this week when I hear from the dealer.
