 And I think they're referring to the human power, the old push type mower. So some places are referred to as a cylinder mower, but reel mowers is a common term for them. So they have a reel that turns, and they cut grass differently than a rotary mower, which had blades that turn. So the blade on a reel mower is stationary, whereas the blade on a rotary mower is the one that spins.
