I see Cat have finally gone away from the D6D design which they incrementally upgraded to the D6G and now build an upgraded D6H and call it the D6GC. 3306 engine, old lever style steering. Made in China maybe? https://www.tractafrictae.com/en/vehicle/caterpillar/191/d6gc/show.html
I’ve seen new dozers like that on the line in Peoria, destined for export only. In fact at the time I was touring the plant they were pretty much only building export and military machines, very few domestic bound machines were there.
