how do lawn mowers work?

Answer 1

gasoline combusts in the engine by the spark plug, and causes a mini explosion within the machine, and the pressure of the 'explosion' causes the pistons to fire down and then a little gas pours onto the piston again and the piston springs up and hits the sparkplug and then the gas turns into a mini explosion again and fires down again. This design is so clever that it causes the piston to keep doing this and thus causes the creation of power. The moving of pistons is converted into a spinning wheel which the blades are attached thereof. 

Don't touch the blade while it is spinning however, or it will chop your fingers and hands off..

Answer 2

There are several types of lawn mowers:people you hire, machines with manual power and machines with motorized power.  Most power mowers tear the tops off the grass with rapidly spinning blades.  The manual mower I grew up with turns sharp blades against an anvil, cutting the grass like large scissors.  Some of those were later redesigned with motors to turn the blades if not also to move the wheels.

Answer 3

they have cutters underneath that cut the grass and petrol to get the engine working.

Answer 4

Chlorophyll stalk slicers of the typical engine/rotating blade type do not cut grass they basically rip the blades in half from the sheer speed of the blade, which is why golf courses don't use them.
