The advantage we have with the New Generation and Generation II is the fact they have proven themselves to be durable machines, as they have stood the test of time. Have they all been perfect? Probably not. I think anyone who has had long term experience with any brand could pick out the more prone problems of any machine. This equipment is not "throw away," so you do keep it maintained. I enjoy operating both our New Generation and Generation II equipment. I have also operated some of the newer 7000 and 8000 series, and the cabs are a joy to spend time in as well as unmatched visibility. Sitting in the cab of an 8000 series makes the Sound Guard cab seem rather crude and confining by comparison, but at least my older equipment is in good shape and paid for. I personally think the 8.1 liter engine was a great step forward from the 7.6 liter, as the latter was simply maxed out in what it could do. Electronics on newer equipment, well, just like everything today, it is great when it works and a headache when it does not. Hydraulic systems have quite a demand placed upon them with operating today's planting equipment, thus they are far more complicated with more to go wrong than what we had 30 years ago. I would also agree with the emission related components. I tend to believe that today's diesel engines (both on and off road) that we faced with gasoline engines in automobiles back in the 1970's. The industry has come a long way since then, and perhaps in another 10 to 15 years, I hope that our diesel engines and their emissions components will be as durable as our automotive gasoline powered engines. The 3020 and 4020 are probably still like a pair of pliers that one would be lost without, and they are classy looking even today. The 4440 is a 15 year newer version of a 4020, for all practical purposes. The 6030 you cite, well, it is in a league all by itself and represents the biggest and the baddest of the New Generation. The 4960 represents the most refined of Generation II and is a pleasure to operate. I don't know if the same will be said about, say, an 8400 or a 7930, or an 8310R. I don't believe they will be parked in salvage yards in 10 or 20 years. I do not think that many of today's large scale farming operations hold their equipment quite as near and dear to them as it was in times past. Equipment is purchased, used, and swapped out fairly rapidly. I have looked at a lot of used tractors over the years, and it surprises me how badly beat up so many of them are. Clean, low hour, well cared for equipment seems to be getting harder and harder to come by. We were fortunate enough to find with the last two tractors purchased, clean, one owner, lower houred equipment, that were both older than 10 years. The prior owners did take care of them and at least seemed to take some pride in the ownership of them.
