Not sure if things are any different. Would the dealers of 30-40 years ago handle this any differently or the manufacturer?
Lemons were made back then too just didn't hear about them thru the power of internet.
I was around mechanical things at the time, and can guarantee that you did hear about lemons before the internet. Today's internet has a faster-acting social media, but information still traveled surprisingly well before the internet existed. A lot of it was face to face. We didn't have internet, so it wasn't unusual to spend a lot of time talking with dealers and technicians. BTW, we called technicians "mechanics" back then. I still do that.
One advantage of that old pre-internet face to face contact is that it has a built in BS filter that the internet completely lacks. Kind of a built in fact checker. At best, social medias like TBN are lopsided because they it is so easy for them to only show one side of a story.
I liked the old pre-JD Yanmars so much I have been considering buying a new one for a while now. That's why I've been following this new Yanmar forum and this particular thread for about half a year. Mauser12 seems patiently enduring things that most wouldn't, and that's part of my problem here. There are some things that aren't explained well.
One is the mechanical work. The problems the the owner is reporting are simple ones. Easy to fix. Mechanics start with diagnosing things, not by replacing parts at random. Even though swapping out parts may be the popular perception of what mechanics do, it is simply not the only way that mechanics work when they really want to diagnose or fix a simple problem.
BTW, pump seals and injectors are rarely specific to one model of tractor. Both are easily tested and rebuilt. And nobody replaces injectors without checking them first. Especially in a area like Western Washington with the multitude of marine Yanmar shops there.
And then there is the whole lemon law thing and this being a new tractor less than a year old and under warranty.....Why would the owner and dealer not simply swap parts or the entire tractor for a different one? There's got to be another side to this.
