Reel mowers have between three and seven blades depending on the model type.
Reel mowers are usually powered by people pushing them or tractors pulling them. Golf courses are most often cut with reel mowers which are pulled by a tractor. Reel mowers which are pushed by people do not cut very high grass well or easily. However, once the lawn is under control, the reel mower's scissor-like cut is healthier for the lawn. Rotary mowers usually have one blade which rotates very fast.
