My selfpropelled LawnBoy is about 3-4 years old and runs great. This is the 3rd one I have owned over the last 25 years. Only this one, I can't mow up leaves in my yard. With the stupid little plastic 'fingers' mounted under the front deck, it just pushed the leaves out of the way. I cut the 'fingers' off today and thought that would help, but the mower just wants to blow the leaves to the front and side. I think it's because of the mulching blade. Does anyone else have any ideas?
