Does this product have a catch bag for grass? If not, what do you do with the cut grass?

It's best for your lawn not to remove clippings, and I never see rows of grass clippings b/c this mower throws them in front of the mower, unlike a side discharge gas mower that often can leave rows of grass clippings.

Thank you for contacting Fiskars. Yes, this mower does have a grass catcher available. Here is a link for more information: http://www2.fiskars.com/Products/Gardening-and-Yard-Care/Reel-Mowers/StaySharp-Max-Grass-Catcher-18

Fiskars makes a grass catcher, but it may be hard to find. My technique is to mow frequently so that the clippings are an inch or less. Reel mowers are most effective when used frequently.
