Dont get me wrong I think Gravely is a good company but I really hated the X Factor deck when it first came out. Now I never tried to side discharge with it I needed a mulching mower. I spent countless hrs under it looking for flaws that were causing cutting issues, it was worse than my XR7 by far. Maybe I got a messed up mower. I sent pics to Gravely I checked pitch, tire pressure to no avail. Nice looking mower at first but then it turned to hate I could not even use it on my jobs. The pics below show the cut quality.
