Rotary and reel
The CPSC mower standard (16 CFR Part 1205) defines two cutting styles. A rotary mower has one or more blades that turn in a flat, horizontal plane. A reel mower turns helical blades against a fixed cutter bar or bed knife, which gives a shearing action.
Walk-behind mowers
The same standard defines a walk-behind power lawn mower as one that is pushed or self-propelled, has a cutting width of at least 12 inches, uses an engine or motor, and is normally controlled by an operator walking behind it. Ohio State University Extension says small walk-behind mowers have single blades and relatively narrow cutting widths.
Riding mowers
Ohio State says riding mowers have multiple blades and wider cutting widths, and are best suited for larger lawns where their size and maneuverability can be accommodated.
Robotic mowers
UF/IFAS Extension describes robotic mowers that use a boundary wire or GPS to define the mowing area, work inside that boundary, and return to a charging station on their own.
Which type fits a lawn?
Ohio State says to choose a power mower based on the size of the lawn, operator experience, and preference. We do not pick a type or a model.
FAQ
General information only. Read the operator's manual before you mow. Keep children and pets indoors or well away from the area you mow, and never let a child ride on a mower as a passenger. The American Academy of Pediatrics says that, in general, children should be at least 12 years old to operate a walk-behind power mower safely and at least 16 to operate a riding mower safely. Before you clear, adjust, or service the blade area, turn the mower off, wait for the blade to stop, and disconnect the spark plug wire; on a battery or corded electric mower, follow the manual to disconnect its power. Refuel outdoors, only with the engine off and cool. Wear sturdy closed-toe shoes and eye and hearing protection. In an emergency, call 911.
