Hover mowers are a niche mower, usually used for a single purpose. They operate similar to a regular rotary mower with a twist. Hover mowers have no wheels and literally "hover" on the surface of the grass. The hover mower's unique ability to float on a cushion of air makes it perfect for mowing steep slopes where wheeled walk behind mowers could slip, mow unevenly or pose a danger.
Hover mowers are often found on golf courses where they are used to mow steep bunker faces and other irregular or extremely contoured areas.
