The NH dealer out here is a blooming idiot, along with their mechanics, if you could call them that! No parts inventory, 30% higher on their tractors, arrogant attitude. That is why I went 650 miles away to an LS dealer in Texas, RCO tractor to be specific. Made the best deal in a 1200 mile radius. Stood behind the tractor sending me parts ( minor issues at time of delivery)plus some extras, and I have Not had A single issue with the tractor at all for the 170 hours put on it in the last 11 months.
As said before, we feel sorry that you have had so many issues with your tractor. You, unfortunately, were one of the unlucky ones to get a “bad” tractor and it was not taken care of. It does not mean that they are all bad. All brands have their issues....
I had a Ford F-350 that was in the dealers service bay for 287 days out of the 385 I owned it! That does not mean that ALL Ford trucks are bad, it means that I was the unlucky guy that got a bad one. It had a total of 2,000 miles on it at a year.... Ford wanted to give me 50% of what I paid for it.... I dealt with it for another 6 months and traded it in, taking the loss, on another F-350.... that one never had a problem for the next 4 years and almost 250,000 miles.
