Are you referring to the first video or the second? In the first video, most trucks would not push that much snow, so I think your referring to the second...
In the second video with the JD... Those roads are pretty narrow... some have some steep dropoffs with no guardrails... I think the machine is moving pretty fast based on the conditions.... But that is me...
I have tried to talk our town into purchasing a machine like the big JD when replacing a plow truck... it has far more power for pushing banks back and making the roads wider..
Last winter many of our roads were down to nearly one way with all the snow....
