So who would go for a 60" rear discharge mowing deck on their current mowing deck if it was available. The ability to use a 60" deck, trim right and left, and not worry about any clumping or clippings in beds on small to medium residentials would be a huge time savings. Upsides: Trim both sides Even discharge of grass Never have clippings in flower beds Little to no clippings on driveway, street, sidewalks, etc... Requires less power since the deck is more open (less airflow restriction). Saves on gas. Great for cutting tall over grown properties. Downsides: Will cost a little more due to extra baffeling if done correctly. Does not mulch as well as side discharge, but will discharge much better. Can't really use a bagger, but who does anyway.
