36" belt drive walk behind. Less than 100 hours. 16 hp Briggs & Stratton Vanguard engine. Optional mulching plate. I purchased this in 2015 from another user as part of a package. When I purchased it, it still had break in oil in engine as he never used it. It has always been my backup machine that I never had to use. Only used to mow my own lawn a few times a year.
