So I looked up these engines and they all turn 3600 RPM's. Snow variables greatly effect the blowers ability to throw along with blower width. The blower width is determined by engine size. Travel speed is a variable also so lets select low and use 4" of fluffy snow as our constant. Lets put the forward lever at full and plow right into it. Shouldn't each tractor throw snow the same distance? What are your thoughts? This post is about distance of snow travel out of the shoot not it's abilities in difficult situations.
