An engine pumps as fast as a car to spin a blade over 50 times a second.

The blade’s twisted ends act like helicopter propellers,creating air currents that suck the grass up and into a container at the back.

The breakneck speed of the blade whips a belt around the machine at the speed of a chain saw,powering the wheels,making this 100-pound machine effortless to maneuver.It can manicure a lawn in minutes.

It’s called the governor,and it’s the lawn mower’s cruise control. It uses flyweights to detect the speed of the blade.

If the crankshaft slows down,the flyweights decelerate,fall inwards,and trigger a lever to open the throttle an pump in more fuel.

This boosts the engine’s power and spins the blade back up to the perfect cutting speed of 3000 times a minute.
