Stick time baby! Looks like a hard faced cliff. No loose material buidling up it all just falls down. This man and his machine are done. We had one called Betsy in my old engineer platoon, she was the oldest, slowest, D7 we had but she once you got a ryrhm she was a beauty.
I would think there would be a certain amount of LOOSE fill that would build up near the "more-solid" ledge. Couldn't that loose fill give way with the weight of the dozer and create a "problem"?
That's why I always double push. One blade full just short of the edge, the next blade full to push the first one over. In reality you feel the front of the tracks go "soft" as thry go over the edge and onto the rill. Once the rill is established you can safely drive out onto it. But, yeah... where I work that operator would be called in for a chat. Edges fail. Always have dirt in front of you.
