Mowing the lawn doesn't have to involve smelly noisy lawn mowers. It can be a sleek and quiet operation. ECO Mowers has an extensive learning section teaching about the impact of mowing the lawn, plus the products they've lined up to help you do it a better way.
Most of the products they have are reel motors, so yeah it will involve manual effort.
They also carry electric mowers and other gizmos for low impact yard care.
