I just read all the posts for the first time. I'm really having a hard time buying the original argument. Is there real evidence that a significant number of newer CUTS have more problems that older tractors did in their day? No one presented evidence to really support this.
Can they really be compared, based on their different uses? No. Impossible really. Maybe you could compare drive trains for shear pulliing power. Here, I might buy into the argument.... maybe.
As far as retaining their value. One must remember that, in the past, there were many periods of much higher inflation. So, if you bought a tractor in 1974 and then went and looked at what it cost for similar in say 1977 (those were years of double digit inflation) what would one expect? Of course your 1974 tractor is worth more in 1977. Inflation rate and economic conditions have a whole lot to do with what a used tractor is "worth". All-in-all CUTS too are holding their values pretty good over the long term given the inflation rate. I contend that, with a few exceptions, everything is better today: more capable, more affordable, more enjoyable, and more reliable.
I hear things aren't as good as they used to be. I completely disagree. Yeah, maybe your TV only lasts 10 years now, but it costs a whole less relative to income. Same is true of just about everything. I'm OK with throw away for a lot of things as long as it's cheap enough to begin with; and that cyclic nature is what drives innovation, product improvement, and economic stimulus. What if never bought more than one of anything over our entire lives? What kind of economy would we have? Where would technology be?
And I still haven't seen an argument that says most CUTS won't be in service 20 years from now. I fully expect mine will be. Shoot my 1994 Garden tractor is just 3 years shy of that mark, and has a good 20 more in it and I've spent a grand total of $75 on repairs.
I contend that, with a few exceptions, just about everything is better today: more capable, more affordable, more joyable, and more reliable, even if not more repairable.
