In all the massive activities associated with the remedial activities in Butte and the actual reconstruction of 22 river miles of Silver Bow Creek, I never saw a Deere. The incredible mess was created by the Anaconda Minerals Company but the obligations fell to ARCO who bought out Anaconda (they lived to regret that). The famous Berkeley Pit and associated superfund activities in Butte, MT including Silver Bow Creek and the Clark Fork River. In 1987, I became a Remedial Project Manager on the largest Superfund Site in the US. In fact, I do not remember a John Deere machine on any of the coal mines I inspected in all those years. I later became a Reclamation Specialist and was on coal mines in KY, VA, West VA, TN, CO, WY, MT, North Dakota, and Alaska. They tried Terex which eventually everyone began to call Timex because they did not hold up. As a reclamation supervisor and quality control engineer for Tesoro Coal Company in Hazard, KY, the Cat was the preferred machine. I have worked around the earth moving profession since 1974 when I went to work in the coal mining fields of eastern Kentucky. First, here is the basis for my observation.

They all seem credible, but here is my observation that seems to indicate to me that when it comes to Dozers, Cat has the advantage. I often read posts that regardless of the subject, people find some way to put in a plug for either a Caterpillar or John Deere based on their preference.
