It is 54 inches. 1/2 inch narrower than what the tractor tires are set at right now. It was too good of a deal to pass up on for a used blower. List price was close to 9000 dollars and I picked it up for 1750. The blower had 8 hours of use on it and came with an extension for loading into a truck. I could narrow up the rear tires, but I like them where they are at. Seems to be working real nice. It really launches the snow compared to my old JD 666 blower. The blower is rated for 50-90 HP but I am real pleased with it at 33 HP
