The 20" wide mower has two quick-release levers easily set the cutting height from 1 7/8" to 3. The four-wheel design adds stability, with 10" front wheels and 6" rear wheels. This 30 lb, five-blade mower comes with the grass catcher. Used for about 1 season, initial cost about $200. I don’t need this one as I recently got a very good deal on a battery mower.
