My 9 y.o. MTD walk behind mower just will not mulch at all and leaves lines of clumped clippings everywhere I mow, for any cutting length greater than, oh, maybe an inch or two.
Is this possibly remedied by getting a new blade and not simply sharpening my old one over and over? I'm suspicious that my dremel tool sharpening of the old blade is not maintaining the precise curve it once had. Does that matter?
I may be getting a new mower---hence my companion post in this ng.
