Hi to all. In browsing through the various discussions in this forum today I have come across a few where the poster was making a statement or statements of questionable authenticity. One such is this one: http://www.ytmag.com/crawlers/messages/2423.html The Komatsu D575 SD3 is NOT the largest 'dozer ever made. Two larger have so far been built and one is still in existence. They are: ACCO: 183 tons, 1350 hp with 2x675hp Cat V8 diesels. Still in storage in Italy. Western 2000: Built in 1963 for Western Contracting for the Milford Dam project in Kansas. It was 170 tons, with a 1450 hp GM diesel running a huge generator that supplied power to a 400hp electric motor in each of the four wheels. This machine was worked until 1981 and I believe it has now been scrapped. There is a grader that is even bigger than either of these machines: ACCO: Grader; 200 tons, 1,000 hp driving the rear tandems, 700 hp driving the front axle, all wheels fitted with dual tyres, and carrying a 33 foot blade. Still in storage in Italy. The next 'expert' is at: http://www.ytmag.com/crawlers/messages/38178.html In this post, the poster makes a statement that Case was the first manufacturer of crawler tractors to make a 'full-power-to-both-tracks-while-turning' crawler steering system. NOT SO. Cletrac were building such a system for possibly thirty years or more before Case even had a crawler tractor. The exact dates I don't know but I'd bet it was quite a while. Check this discussion: http://www.cletrac.org/forum/viewthread.php?tid=261&pid=1118#pid1118 No doubt there are more that I have missed but that is enough for now. As mentioned in some earlier posts, many of those who come to this forum are hobbyists and/or newcomers to crawler tractors and are looking for the best help they can get. I personally believe that as an experienced operator it is my responsibility, if I choose to post on this site in answer to other's queries, to give the most reliable and accurate answers I can. That is my aim. Unfortunately, I can not make that the aim of everybody who might post answers here, but I can hope. I don't want to make any enemies here but I want to see MIS-information posted even less. You all have a wonderful day. Best wishes. Deas Plant.
