OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Walk Behind Lawn Mower Frames Question On Scott Bonnar Cylinder Mowers Scott Bonnar 45 17"

It cuts only the outside 2" .I have cut he grass (couch) and the result is very good the best I have ever seen but i get a line each side of the cut and it requires me to go over it again to even the cut. The mower has a new bed plate and it may be the problem .Thanks for the response.
