If you have a particularly large area of grass to mow, over a tennis court in size, you will benefit greatly from purchasing a large pedestrian lawnmower, machines that usually have cutting widths of 53cm to 56cm. These are broad, bulky machines that are all self propelled and necessarily so, they are simply too big to push around for any length of time. If you have ornaments or detailed areas to negotiate, buy a machine with speed control to enable you to adjust your working pace to the conditions in front of you. The grass bags of these mowers are large to accommodate the extra grass clippings that are produced, and you may find that if you have mixed types of grass, as large gardens often do, a 4 wheel rotary mower will be your first choice due to its ability to adapt to differing conditions. However, if your grass is uniform and the lawn area is free of obstacles, a large rear roller lawnmower will be an excellent choice, especially if you like the idea of stripes on your lawn.
