I have been coming to this site for awhile now and just decided to sign up. I am just now doing research to start a new business. I am researching mowers and feel the only one's I can afford are W/B's. Do walk behinds leave the same distinct lawn stripes as a Z. I know that SCAG has a roller sytem that is designed just to leave stripping. Do any other brands use a similiar system? Thanks in advance for everybodies help.
