If you have a manual push mower today, it likely uses design elements from 19th Century Black American inventor John Albert Burr's patented rotary blade lawn mower.
On May 9, 1899, John Albert Burr patented an improved rotary blade lawn mower. Burr designed a lawn mower with traction wheels and a rotary blade that was designed to not easily get plugged up from lawn clippings. John Albert Burr also improved the design of lawn mowers by making it possible to mow closer to building and wall edges.
