Cool video, thanks for posting it. Snowblowers sure are the great equalizers in tractor size aren't they? The setup you have there seems to work great!
Here's what you can do with chains on the front and rear tires. Once you run out of space to pile the snow you have little choice but to go higher.
I am going to try and find a used snow blower this week
Great video, I have a four month old pto mounted snowblower, mounted on a four month old Kubota B7510, don't know how I kept my 300' gravel driveway clear before I got this setup.
