Thats excellent to read!
Its ashame it was a Sunday and no one was around to talk too. The one with the square leg barrels...(they steer too?) and whats the PTO/gearbox with the handle on it? You engage the clutch by hand? The costs of mobilization of those big machines has ended their careers, two halflane mills can outproduce them easily these days and cost much less to run.
It looked like 2 of those PR1200 mills came from Arizona Pavement Profiling. One of the other ones had an L&L logo faded of it, they are a big outfit from Michigan.
Still, I'd love to see one of them in the ground at full rip....
