What dozers did you operate? I have been watching Clint at C&C equipment for about a year. He buys non-operating dozers at auctions and by word of mouth and rebuilds them. He has a Utube channel and posts the progress on his current projects. Back years ago my wife took care of a bunch of horses for a local farmer and his girl friend. One day I noticed 2 large dozers near the horse barn. He told me the Komatsu would do 25% more work on 25% less fuel than the Cat. I was skeptical! then I started looking them over. The Komatsu was new and the Cat was built in 1948.
