I have a 4115 w/ 47" FM blower. I was skeptical with it more narrow than the wheelbase. Dealer said don't worry, it will eat what you throw at it. No snow worth discussing this year but, last year it ate anything I threw at it. Not having had a real good dump of snow, last year, I decided to see what it would do with the 3' packed snow on my woodroad that had not been cleared all winter. Admittedly, I had to go a bit slow but, the blower threw it all 50' off into the woods, clearing about 300' of 3' deep snow in maybe 15-20 minutes. Price? Yup, choked on it but beats turning around to use the rear blade or having bought a rear blower. JMHO
