I have a 60" blade on my 50" Razor. When set at an angle, it just clears the tires. It'll take a little more power to push a 66". I don't know if the Honda has it or not. Mine is an 800. I bought it 4 years ago just as we were entering a drought that's still going. I haven't plowed more than 4" at a time in 4 years.

“In a time of deceit telling the truth is a revolutionary act.”
― George Orwell

It's not over when you lose. It's over when you quit.
