A wheeled device with a specifically crafted blade designed for
cutting grass. Usually has 4 wheels and is pushed along like a
shopping trolley, though sometimes they are small, automated 2 wheel machines, and in some cases are much larger and
have a seat for riding on, for especially large lawns. The medium ones are often characterised by having a very sudden and forceful yanking of a cord to start the motor, or sometimes the noise they make.
