Whole lotta NOPE for me on that plow! :laughing:
As for the angle, I got to thinking about it. If you angle the blade to push snow to the right, that would kick the front to the left if it jammed on something, which could force the rear of the machine to the right, and off your rear goes over the edge.
So conversely, if you angle the blade to push the snow to the left, you'll see if the front starts getting pushed to the right if the blade jams on something, and stop before the front goes over the edge.
That's my guess. Someone go interview the drivers and see what they say.
