What happens when you run out of places to push the snow?
As far as the ex mower, I'm watching this thread too. Been using brush mulchers on skid steers for about 10 years and looking at trying an excavator mulcher for some specialty jobs and for use on my own place. I've not owned a US mower but they look like they would hold up well.
