I haven’t been aggressive yet and hence I am not naming dealer nor manufacturer. How many times should I be without a tractor whilst it’s continually fixed. I have no issue with the dealer just fed up having continual break downs and lost time, which comes at my expense. Once warranty is up what do I do with the repairs?It sounds to me like the tractor has had issues and in each case it has been repaired by the dealer. And again they are wanting to take it in to get to the bottom of it.
From what you've posted the dealer has done it all by the book and you have no grounds to complain.
You've just got to let them do their thing which unfortunately may take time.
One thing I do know is the more aggressive you are with them (anyone for that matter) the more uncooperative they will become. That's just human nature.
