Jerkiness might be relative to what you are comparing it too. All three orange machines that I have owned to me seem normal, guess…they are very similar…the MX seems to be a little jerky at speed but that is due to the bounce and shitty seat on it. I would consider them responsive. I also rarely use the break. Spousal unit thinks they are jerky but she has a much different style of driving which I don’t believe anyone ever accused her of being a smooth driver…there is no safe drinking of coffee in a car truck or tractor if she is driving. So it may be relative. Maybe compare to another similar tractor and see if feels the same or very different. Remember the electric track race cars we had as kids with the trigger control…some kids were smoother than others…may just need some time doing delicate work and things will smooth out. I also very rarely move the tractor out of low…it seems jerky to me in mid though. Personally I think drive by wire in new cars has ruined peoples touch with the accelerator pedal…I’d much rather have some feedback which helps in smooth. Without comparing to a similar tractor side by side it’s hard for anyone to say I think…IMO. As far as the loaders the MX is most certainly smoother than the B or BX I used to have.
